Speaker 1: Prof. Dr. rer. nat. Carsten Culmsee, Institute for Pharmacology and Clinical Pharmacy, Faculty of
Pharmacy, University of Marburg, Germany

Title of the talk: Role of Mitochondria in converging points of oxidative cell death and neuroinflammation

About Speaker:  Carsten Culmsee is Professor for Clinical Pharmacy and Vice Dean of the Faculty of Pharmacy at the University of Marburg, Germany. His research focus is on the regulation of mitochondrial integrity and function in paradigms of programmed cell death, inflammatory processes and metabolic impairment contributing to neuronal dysfunction and death in neurodegenerative diseases, such as Alzheimer’s and Parkinson’s disease, in ischemic brain damage, and in psychiatric diseases. In addition to the experimental work he also leads a group of Clinical Pharmacy where he guides research in the clinic and in public pharmacies on contribution of pharmacists in drug safety and interprofessional patient care. In the seminar he will provide latest results on the role of mitochondria and metabolic regulation in paradigms of oxidative cell death and neuroinflammation with relevance to age-related disorders and longevity.


Speaker 2: Assistant Professor, Paola Perrez Pardo, Utrecht Institute of Pharmaceutical Sciences | Division of Pharmacology

Dept of Pharmaceutical Sciences | Faculty of Science | Utrecht University

Title of the talk: Gut vibes in Parkinson’s disease: The microbiota-gut-brain axis.

Abstract: The causes of Parkinson’s Disease (PD) remain unknown, but many data indicate that neuroinflammatory responses, including activated microglia and increased cytokine expression, exacerbate dopaminergic neurons degeneration. Thus, targeting the signaling pathways responsible for (neuro)inflammation may represent a promising new therapeutic approach to preserve remaining neurons in PD patients and possibly also to extend the window of efficacy of existing symptomatic drugs. The intestinal tract and its microbiota community can be regarded as a contributing factor to the neurodegenerative processes in PD through the dysregulation of the gut-brain axis which is a bidirectional communication system between the central nervous system and the intestinal tract. Mucosal inflammation and intestinal dysfunctions are common in PD and sometimes begin decades before the onset of motor symptoms. In this talk, I will  focus on the in vivo and in vitro work we perform at our group to study the contribution of the gut microbiome in PD and how microbial derived therapies might impact disease progression.


10th of April 2024, 16-17:00 CET

Speaker 1: Associate Professor, Linette Willemsen, Pharmacology, Utrecht University, Mucosal Immunology and Pharma & Nutrition

Title of the talk: Allergy preventive effects of (human milk) oligosaccharides in preclinical models of allergic sensitization

About Speaker: My research focusses on the mechanisms by which specific dietary components such as fermentable fibers and their bacterial fermentation products, or n-3 long chain poly-unsaturated fatty acids reduce the risk of developing non-communicable immune disorders such as food allergy or asthma. These components improve mucosal and/or systemic immune function as we showed in vivo, and in human in vitro co-culture models studying the crosstalk between structural (epithelial cells) and immune cells. Recently we developed a sequential series of co-culture models mimicking the allergic sensitization cascade, in which we studied the immunomodulatory effect of human milk oligosaccharides on allergen induced type 2 activation. By creating awareness for the beneficial effects of dietary components on immune health, I hope this will lead to their future use as adjunct therapy to support pharma. In this talk, I will explain the rational behind our recently developed in vitro models to study allergic sensitization and I will show some allergy and asthma protective effects of non-digestible oligosaccharides.


Speaker 2: Assistant Professor, Karim Rafie, Molecular pharmacology, Groningen Research Institute of Pharmacy, Groningen

Title of the talk: Visualising human adenovirus capsid structures with cryo-EM – Insights into tissue selectivity and receptor binding

Abstract:  Viruses are one of the most ubiquitous pathogens and are a constant cause of disease. However, our understanding of how viruses alter our cells to benefit their replication is still poorly understood. In my lab, we aim to elucidate the mechanisms through which viruses modify mitochondria to facilitate viral replication. Our comprehensive approach combines x-ray crystallography, cryo-EM, and in situ cryo-ET with techniques from biochemistry, cell biology, and virology. The knowledge gained from our studies will contribute to the development of novel antiviral strategies.


6th of March 2024, 16-17:00 CET

Speaker 1: Prof. Wiktor Szymański, Department of Medicinal Chemistry, Photopharmacology and Imaging, Groningen Research Institute of Pharmacy, University of Groningen

Title of the talk: Photopharmacology: concepts, tools and applications

About Speaker: Molecular photomedicine holds the promise for precise treatments, which avoid systemic adverse effects and development of drug resistance. This promise is supported by current medical imaging modalities that are able to reveal the nature and location of malignancies, such as cancer and infections. At the same time, biomedical engineering has recently created methods to deliver light deep into human body. The photomedicine puzzle is currently missing its final piece – the way of translating light into a therapy. To address this challenge, drugs could be introduced whose activity could be reversibly or irreversibly controlled. The aim of this presentation is to describe the emerging concept of photopharmacology, which is currently being developed and applied to precisely control the activity of drugs using light.


Speaker 2: Dr. Angelica Sabogal, Department of Molecular, Cell Biology and Immunology, Amsterdam UMC
(The presented work was performed during my Postdoctoral fellowship at the University of Groningen)

Title of the talk: The importance of microglia in metabolic changes of the brain: A world to explore

Abstract: Our research within the group of Dr. Dolga (University of Groningen, The Netherlands) focusses on understanding metabolic changes in basal and pathological conditions. Microglia are involved in metabolic reprogramming in response to inflammatory stimuli. In order to delineate inflammatory responses that are specific to murine and human microglia, we investigated the transcriptomic and metabolic profiles of mouse and iPSC-derived human microglia challenged with the TLR4 agonist LPS. We found that both species undergo metabolic reprogramming and displayed an overall increased glycolytic gene signature in response to LPS, although the metabolic pathways involve different enzymes in human microglia compared to murine microglia. We highlight these species-specific pathways involved in immunometabolism and the importance of considering these differences in translational research for potential therapeutic agents in neurodegeneration.


21st of February 2024, 16-17:00 CET

Speaker: Prof. dr. ir. Ingrid Dijkgraaf, Dept. of Biochemistry, Maastricht University

Title of the talk: Peeking at blood-sucking parasites to treat cardiovascular diseases

About Speaker: Our research within the Department of Biochemistry at CARIM (Cardiovascular Research Institute Maastricht, The Netherlands) focusses on peptides and proteins that play a major role in cardiovascular diseases. Ticks express a vast variety of anticoagulant, anti-inflammatory, immuno-modulatory, and vasodilating proteins that evade or counteract host defense mechanisms. Therefore, these
organisms represent major sources of lead compounds for the development of pharmacological tools, such as imaging agents to unravel molecular pathways, and potentially useful therapeutic agents for treatment of haemostatic disorders and cardiovascular diseases.


31st of January 2024, 16-17:00 CET


Speaker 1: Prof. Matthew Groves, Associate Professor, Faculty of Science and Engineering, University of Groningen, Groningen, The Netherlands

Title of the talk: Allosteric inhibition in aspartate transcarbamylase: Applications from malaria to herbicides

Abstract: Pyrimidine biosynthesis is an essential function in all living cells and is supported by two distinct pathways:   de novo synthesis and salvage. Different cell types are more dependent upon different pathways, but generally rapidly dividing cells are dependent on de novo synthesis. Aspartate transcarbamylase catalyses the first committed reaction in this pathway and is therefore an attractive drug target for multiple systems. However, the current ATCase gold standard inhibitor is a transition state mimic and has limited selectivity between human and pathogens. In this talk, I will describe the discovery of a new allosteric inhibitor of ATCase and its potential in multiple disease systems and as a herbicide.


Speaker 2: Hong Yan, PhD student at the department of Molecular Pharmacology, Groningen Research Institute of Pharmacy, Groningen, The Netherlands.

Title of the talk:Air pollution particles accelerate RSL-3-induced ferroptosis in HT22 cells via cAMP-Epac1 pathway

Abstract: Air pollution exposure is one of the important threats to human health. Diesel combustion produces diesel exhaust particles (DEP) which seem to contribute to the onset of different neurological diseases due to the induction of oxidative stress, inflammation, and neuronal degeneration. Underlying molecular mechanisms are ill-defined. RSL-3-induced neurotoxicity has been linked to the newly identified iron-dependent form of cell death ferroptosis. Cyclic adenosine monophosphate (cAMP) seems to be linked to the ferroptosis type of cell death in processes involving Epac (exchange protein directly activated by cAMP. In this talk, I will describe a potential interaction between RSL-3-induced neurotoxicity and DEP, and discuss the role of the cAMP-Epac1 pathway in the combined cell death.


13th of December 2023, 16-17:00 CET

Speaker 1: Dr. Rick Greupink, Department of Pharmacy, Division of Pharmacology and Toxicology, Radboud university medical center, Nijmegen.

Title of the talk: Development and application of in vitro, ex vivo and in silico models to assess placental transfer and effects of drugs

Abstract: The placenta plays a key role in maintaining a healthy pregnancy. To improve drug safety during gestation, it is relevant to understand to which extent and at which rate drugs are transferred across the placenta. While crossing the placenta, pharmaceuticals may also affect placental function. Pregnant women are not readily enrolled in clinical pharmacology trials, therefore data on drug efficacy and safety during pregnancy are scarce or become available only at a late stage after market introduction of a pharmaceutical. Translational pharmacology studies based on human tissues and cells are becoming increasingly important to fill this knowledge gap. In my talk I will highlight several ex vivo and in vitro models that we use to investigate the placental disposition and effects of small and large molecule pharmaceuticals, as well as how non-clinical pharmacokinetic data may be used in combination with physiology-based pharmacokinetic (PBPK) modeling to better understand clinical pharmacology during pregnancy.


Speaker 2: Dr. Manoe Janssen, Div. of Pharmacology, Department of Pharmaceutical Sciences, Utrecht University, the Netherlands

Title of the talk: Advanced in vitro cell models to study genetic kidney diseases – An in vitro adventure

About Speaker: My research group is embedded in the group of Prof Dr Roos Masereeuw at the division of Pharmacy at Utrecht University. I specialize in the field of genetics and genetic disease, with a focus on genetic kidney diseases and lysosomal storage diseases. We use CRISPR/cas technology to develop new disease models and therapies. It is my ambition to improve the translational value of in vitro models and in this way contribute to the development of new therapies.



22nd of November 2023, 16-17:00 CET

Speaker 1: Dr. Ard Teisman, Dept. Global Safety Pharmacology – Jansen Pharmaceutica / Johnson & Johnson Innovative Medicines, Beerse, Belgium

Title of the talk: The Use of Stem Cell Models in a Drug Selection De-Risking Cascade

About Speaker: since I joined Janssen Pharmaceutica back in 2001, I’ve been involved in Safety Pharmacology and helped drug discovery-projects in their search of finding the best and safest drug-candidates to move this forward along the pipeline. The field of Safety Pharmacology differentiates on one end from Pharmacology in that it assesses unfavorable side effects of drug candidates and on the other end from Toxicology in that it looks for unfavorable physiological changes and not for direct structural tissue damage. This objective has an impact for the models, methods and strategy used. Within our team we apply in silico, in vitro and in vivo models in an integrated cascading fashion and look for complementary end-points across the models. Along my career the use of stem-cells models in de-risking strategies gained importance and at a certain point in time replaced a traditional animal-based pharmacology model. The learning curve, stepped approach, characterization (understanding opportunities and limitations) and decisions leading to this transition will be illustrated in this webinar.


Speaker 2: Annika Jüttner, PhD candidate, Pharmacology and Vascular Medicine, Erasmus Medical Centre, Rotterdam

Title of the talk: Effects of hibernation inspired modified 6-chromanol SUL-238 on vascular aging

Short summary:Vascular aging is marked by decreased vasodilation including lower nitric oxide (NO)– cyclic guanosine monophosphate (cGMP) –signaling. This can be partially and transiently compensated by endothelium-derived hyperpolarization (EDH) to avoid total loss of vascular function. Increased levels of reactive oxygen species (ROS) in the vasculature, believed to be produced by mitochondria, lead to loss of NO during aging. Both vasodilator pathways, NO-cGMP- and EDH-signaling, are potential drug targets to alleviate aging-related dysfunctions and targeting both would be an ideal mechanism for a new drug. The recently developed drug class of SUL-compounds, modified 6-chromanols, was shown to decrease ROS-production by inhibiting reverse mitochondrial electron transfer. In this talk, the effect of chronic treatment with the compound SUL-238 on vascular aging in mouse models will be discussed, highlighting NO-cGMP signaling, EDH signaling, and other aspects of vascular disease.


15th of March 2023, 16-17:00 CET

Speaker 1: Dr. Matthijs Blankesteijn, Dept. of Pharmacology&Toxicology, CARIM, Maastricht University

Title of the talk: Interventions in WNT signaling stimulate cardiac regeneration

Short summary: Myocardial infarction (MI) is a common cardiovascular event, frequently causing heart failure. This is due to cardiomyocyte loss and replacement by scar tissue in the infarct area, resulting in excessive dilatation of the ventricles. During normal wound healing after MI, the low rate of proliferation of cardiomyocytes in adult mammals prevents regeneration of the lost cardiac tissue, shifting the balance towards a massive fibrotic response. Therefore, investigations aiming to redirect the wound healing process away from scar formation, into the direction of cardiac regeneration have high scientific and societal potential. Interestingly, complete regeneration of the heart after injury has been demonstrated in zebrafish and newborn mice, underscoring its potential. Previous research has shown that multiple signaling pathways, including WNT signaling, are associated with the induction of cardiac regeneration in zebrafish and new-born mice. In the meantime, a rapidly growing body of literature has been published, showing the beneficial effects of interventions in WNT signaling in infarct healing in adult mammals. In this presentation, I will discuss the different pathophysiological mechanisms involved in infarct healing and the potential effects of interventions in WNT signaling on them.


Speaker 2: Wulf Tonnus, MD, clinician scientist, University Hospital Dresden

Title of the talk: Drugging cell death to modulate inflammation

Short summary: Based in intensive care medicine, nephrology, and solid organ transplantation, Dr. Tonnus works on the delicate interplay of regulated cell death and inflammation. Whereas apoptosis was long seen as a synonym for regulated cell death, this nowadays encompasses various forms or regulated necrosis. Thus, necrosis became druggable raising new questions: Why so many pathways of regulated cell death? Why so complicated biochemistry to just get rid of a cell? Dr. Tonnus utilizes translational models of acute kidney injury to investigate the relative contribution of various forms of regulated necrosis such as necroptosis, ferroptosis, and pyroptosis and their inflammatory consequences. Whereas necroptosis and pyroptosis rely on enzymatic reactions to proceed, these are relatively easy to pharmacologically modulate. As ferroptosis relies on iron-dependent lipid peroxidation, this mode of cell death is particularly difficult to block in vivo. Here, Dr. Tonnus already demonstrated efficacy of different radical trapping agents in ameliorating acute kidney injury. Furthermore, he was involved in the development of the first combined inhibitor of both necroptosis and ferroptosis, Nec-1f. Dr. Tonnus aims to bring modulation of regulated cell death from bench to bedside.


15th of February 2023, 16-17:00 CET

Speaker: Dr. Robert I. Menzies, Director of Bioscience, Research and Early Development Cardiovascular, Renal and Metabolism, BioPharmaceuticals R&D, AstraZeneca

Title of the talk: Driving the next generation of drug discovery for kidney diseases

Short summary:The next generation of treatments for kidney disease demands drugs that can achieve ever greater efficacy with the potential to stop disease processes, or maybe even cure them. This bold ambition requires a significant investment in research and development. In this talk you will learn about why we in AstraZeneca place great importance on scientific innovation together to drive drug development, and will highlight how we are using state of the art technologies and data resources to select the right therapeutic target for kidney disease. Time allowing, examples in small molecule and RNA approaches will show how we are developing novel pharmacological capabilities.


18th of January 2023, 16-17:00 CET

Speaker: Professor Elizabeth (Liesbeth) de Lange, Predictive Pharmacology research group, Division of Systems Biomedicine & Pharmacology at the LACDR, University of Leiden

Title of the talk: Predicting Drug Pharmacokinetics in the Central Nervous System – The Physiology-Based LeiCNSPK3.0 Mathematical Model and its applications

Short summary: Professor Elizabeth (Liesbeth) de Lange started researching neurotransmitters in fish brains at the Department of Neurology at the UMCG (then AZG) and graduated in Biophysical Chemistry at the University of Groningen. Her studies included a lot of mathematics and animal research. She then came to LACDR for her PhD research into a method for measuring brain concentrations as a function of time and location in laboratory animals: the microdialysis technique. Subsequently, this technique was further used and refined and brought many new insights into, among other things, the blood-brain barrier transport and brain distribution of drugs. This technique can be used to measure in human CNS, but this is highly limited by ethical restrictions, to only exceptional cases. The translation to humans must therefore take place via laboratory animal research and advanced mathematical modelling.

Liesbeth’s motto is that we cannot gain deep insights and make good predictions about complex situations if we use a simple approach. We need longitudinal and interrelated plasma and microdialysis data from different locations in the CNS in individual animals (smart data). This is complex and demanding, but necessary for the development of more general mathematical models that capture in-depth knowledge and insights. In addition, it contributes to the reduction and replacement of laboratory animals.

The Predictive Pharmacology research group (PI Liesbeth de Lange) continues to focus on CNS pharmacology and mathematical model development, but also on systems biology of rat Alzheimer’s disease using metabolomics and molecular biological techniques.


7h of December 2022

Speaker 1: Assistant Professor Sébastien Foulquier, Pharm.D., Dept. of Pharmacology- Toxicology, Maastricht University

Title of the talk: Hypoxic signaling in oligodendrocyte precursor
cells: relevance for cerebral small vessel disease

Short summary: White matter lesions are a hallmark of cerebral small vessel disease. Imaging studies have shown their association with decreased cerebral blood flow and increased blood brain barrier permeability. In this lecture, I will highlight the impact of hypoxia on oligodendrocyte precursor cells and how this may affect the cerebral small vessels.



Speaker 2: PhD student, João Faria, Dept. of Pharmaceutical Sciences, Utrecht Institute for Pharmaceutical Sciences

Title of the talk: Efficacy of mesenchymal stromal cells in ameliorating renal ischemia-reperfusion injury in vitro

Short summary:  Kidney ischemia/reperfusion injury (IRI) is the leading cause of acute kidney injury (AKI). The current standard of care is focuse on treatments to support kidney function, stating the need for more efficient and specific therapies aiming to revert the injury. Mesenchymal stromal cells (MSCs) have been proposed as a novel cell-based regenerative therapy, showing promising results in several preclinical applications. However, its full potential in AKI is still unknown. In this talk, I will describe an in vitro model that can replicate key IRI features and discuss the role of MSCs in treating this type of injury.

29th of June 2022

Speaker: Prof. Dr. A.H. (Anke-Hilse) Maitland-van der Zee , Hoogleraar Precision Medicine in Respiratory, Amsterdam UMC

Title: Precision Medicine in Respiratory Diseases

Abstract: Chronic respiratory diseases are multifaceted diseases. They comprise multiple phenotypes, which might benefit from treatment with different types of targeted therapies. Refining these phenotypes and understanding their underlying biological structure would help to apply precision medicine approaches. Using different omics methods, such as (epi)genomics, transcriptomics, proteomics, metabolomics, microbiomics, and exposomics, allowed to view and investigate respiratory diseases from diverse angles. In this talk I will give some examples of precision medicine approaches that are (hopefully) close to
implementation in clinic.

16th of March 2022 

Speaker 1: Prof. dr. R.H. (Rob) Henning, Professor of Pharmacology, Faculty of Medical Sciences, University of Groningen

Title: Hibernation inspired drug development.

Rob Henning explores the molecular mechanisms enabling the miracles of mammalian hibernation: a repetitive, rapid and reversible reduction of metabolism by over 90%, leading to a drop in body temperature close to freezing. Endogenous production of H2S takes center stage in protecting cells from damage during hibernation dictated swings in physiology. He will explain why hibernators inspired the team to search for allosteric modulators of cystathionine beta synthase (CBS) and how they approach the discovery of this new drug class.



Speaker 2: PhD candidate Mohammed Saleh, Leiden Academic Center for Drug Research

Mohammed studied pharmacy in Egypt and did his master’s in pharmaceutical sciences at Utrecht University. In between, he gained experience on the drug industry at Novartis.


Title: LeiCNS-PK3.0: a framework leveraging multiscale data for accurate brain PK predictions

Abstract: Assessment of the unbound drug concentration in the central nervous system (CNS) is crucial for drug development to evaluate efficacy of CNS drugs and the safety of non-CNS drugs. Measuring the unbound drug concentration in the CNS target sites, i.e. brain cells and the surrounding extracellular fluid (brain ECF), is limited by ethical restriction of the human brain sampling, while lumbar cerebrospinal fluid (CSF) has been shown to be an inaccurate surrogate of the drug concentrations in the brain. The Leiden CNS pharmacokinetic predictor (LeiCNS-PK3.0) is a physiologically based pharmacokinetic model that was previously demonstrated to adequately predict the CNS PK profiles. LeiCNS-PK3.0 accounts mechanistically for the CNS physiology, a feature that allows interpopulation and interspecies translations of the PK profiles. In this webinar, we will explore the LeiCNS-PK3.0 model development and application to predict the brain PK profiles in Alzheimer’s patients.


16th of February 2022 

Speaker 1: Dr. Amalia Dolga, Associate Professor in Regenerative Neuropharmacology at the University of Groningen

Upon appointment as a Rosalind Franklin Fellow at the Groningen Research Institute of Pharmacy, she established a molecular neurobiology unit within the molecular pharmacology department. Her laboratory aims at identifying the molecular mechanisms responsible for cell death and at elucidating their involvement in human diseases.


Abstract: Progressive neurodegenerative diseases, including Alzheimer’s or Parkinson’s disease afflict millions of people worldwide. To address this unmet clinical need, it is important to gain more insight into the molecular mechanisms that drive neurodegenerative disease pathology. As mitochondrial dysfunction and inflammation are responsible for the initiation and progression of the neuropathology, proteins that prevent deregulation of both pathways are considered as drug targets. During this talk, I will discuss about mitochondrial dysfunction in iPSC-derived neurons from Alzheimer’s disease, and metabolic reprogramming in mouse microglia and human iPSC-derived microglia.

Pharmacology in a company setting: contributions to ‘go/no go’ for drug selectivity in a translational science context; to MOA, and Biomarkers.

Abstract: Pharmacologists fulfil essential roles in drug development projects, no matter if the drugs are biologics or chemical entities. In a company setting there is always multidisciplinary teamwork in the non-clinical, and clinical context. Activity of a potential drug is always considered in the context of its safety and ADME properties in humans as the ultimate goal. This presentation will give examples of projects with specific ‘context’ problems and how these problems were overcome to get a clear ‘go’ or ‘no go’ for the project.

Title: Application of the Adverse Outcome Pathway (AOP) concept to understand the impact of environmental risk factors on the progression of age-related memory loss leading to Alzheimer’s Disease.

Abstract: While aging and genetics are important risk factors for acquiring sporadic Alzheimer’s disease (sAD), systemic and environmental factors are increasingly recognized to contribute to this risk in a still poorly understood way. Inspired by the tau-cascade hypothesis, a tau-driven AOP towards memory loss was constructed using existing (primarily) human data selected according to predefined selection/rejection criteria. Sequences of key events (KEs) and plausible key event relationships (KERs) triggered by the bidirectional relationship between brain cholesterol and glucose dysmetabolism were captured. To portray how environmental factors may contribute to sAD progression, information on chemicals and drugs, that experimentally or epidemiologically associate with the risk of sAD were mapped on this AOP. The result suggests that chemicals may accelerate sAD progression by plugging into 26 different sAD relevant molecular initiating events (MIEs). A complex network of aging-related homeostatic pathways that are sensitive to an accelerated deterioration in the presence of risk factors is implicated in the pathogenesis of e.g., sAD. Since sAD pathology and neurotoxicity share microRNAs (miRs) regulating common as well as overlapping pathological processes, literature was searched for miRs associated with human sAD and environmental neurotoxicity. Functional miR analysis using PathDip resulted in miR-target interaction networks linked to brain cholesterol and glucose dysmetabolism as well as KEs of the tau-driven AOP. While miR analysis confirmed most of the retrieved findings, 40 miRs were found to be involved in both sAD and neurotoxicity and to dysregulate key processes of the AOP. Creating miR-target interaction networks related to the pathological processes involved in early sAD progression, and environmental chemical-induced neurotoxicity, respectively, provided overlapping miR-target interaction networks. This overlap offers an opportunity to create an alternative picture of the mechanisms underlying early sAD progression. Looking at initiation and progression of sAD from this new angle may open for new biomarkers and novel drug targets for sAD before the appearance of the first clinical symptoms.


15th of December 2021

Prof. Martina Schmidt, Department of Molecular Pharmacology, University of Groningen

Title: Pharmacological targeting of nanocompartments in COPD and Alzheimer’s disease.

Abstract: Chronic diseases afflict millions of people of our worldwide aging society causing individual suffering and an enormous economic burden on our health care system. Chronic obstructive pulmonary disease (COPD) and Alzheimer’s dementia are common chronic diseases threatening the world population. COPD and Alzheimer’s dementia show tissue degeneration, inflammation and oxidative stress. Environmental stressors such as air pollutants and smoke are traditionally linked to COPD. Recent research had shown that people living in highly polluted areas have a higher risk in developing Alzheimer’s dementia. Despite the global impact of COPD and Alzheimer’s dementia, there have been very limited breakthroughs in our understanding and insights into the underlying mechanisms into their causes, treatment or cure. Clustering of cyclic nucleotide (and calcium) signaling in defined subcellular compartments/microdomains (signalosomes) has developed as a promising route to pursue to shed light into the mechanism enabling cells to exert their highly specialized tasks. Drugs used to alleviate COPD and Alzheimer’s dementia symptoms are beta-agonists and phosphodiesterase (PDE) inhibitors. The molecular drug targets of these drugs – beta-adrenergic receptors and PDEs – are key players in compartmentalization. Our research team enrolled unconventional compartment players such as A-kinase anchoring proteins and exchange proteins directly activated by cAMP, and yet to be further characterized targets. We showed that endogenous signaling properties of these multi-protein complexes define drug action – processes being disturbed under disease conditions. To increase the probability to reprogram these multi-protein complexes and to subsequently restore their cellular function, we used approved drugs in combination with novel druggable components to achieve direct pharmacological targeting of nanocompartments. Our concept potentially not only holds for COPD and Alzheimer’s dementia but also for other chronic diseases.

I reach out to colleagues – both at university and company settings – to share knowledge, tools and compounds to develop novel compartmentalized treatment strategies.

Title: Underlying mechanisms of ferroptosis in Alzheimer’s disease.

Abstract: Alzheimer’s disease (AD), the most common form of dementia, currently affects 40–50 million people worldwide. Despite the extensive research into amyloid β (Aβ) deposition and tau protein hyperphosphorylation (p-tau), an effective treatment to stop or slow down the progression of neurodegeneration is missing. Emerging evidence suggests that ferroptosis, an iron-dependent and lipid peroxidation-driven type of programmed cell death, contributes to neurodegeneration in AD. Therefore, how to intervene against ferroptosis in the context of AD has become one of the questions addressed by studies aiming to develop novel therapeutic strategies. However, the underlying molecular mechanism of ferroptosis in AD, when ferroptosis occurs in the disease course, and which ferroptosis-related genes are differentially expressed in AD remains to be established. Our objectives are to 1. analyze which ferroptosis-related genes are differentially expressed in AD brain dependent on cell type, disease progression and gender, and 2. to compare the expression of ferroptotic markers between a) white and grey matter, b) Aβ versus non Aβ areas containing areas and c) high p-tau versus low p-tau-related areas of human post-mortem brains. Future studies should focus on developing new tools able to demonstrate where and when cells undergo ferroptosis in AD brain and build more translatable AD models for identifying anti-ferroptotic agents able to slow down neurodegeneration.

Title: Modeling of vascular aging and drug target identification with DNA repair mutant mice.

Aging is the single largest cause of disease in economically advanced societies. Cardiovascular disease is strongly represented in this context. Non-atherosclerotic vascular aging is a growing topic, its implications in health and life span being increasingly appreciated. This used to be a problematic filed of research due to the lack of convenient methods. In recent years I have developed mouse models to explore this type of vascular aging, namely by partial inactivation of DNA repair in vascular cells. Persistent activation of DNA damage response leads to accelerated development of aging features independently from the presence of risk factors. In my presentation I will illustrate how this impacts cardiovascular function in comparison to the typical risk factor-induced problems.  Also, I will show how my lab has identified relevant drug targets using accelerated vascular aging mice.

Very recently I have developed an interest in redox regulation, and I am trying to develop this as a research line, again placing drug development center stage. My lab does not have all the required experience and facilities to examine important aspects of redox regulation, and I kindly invite anyone skilled for collaboration. Furthermore, we are collecting tissues continuously and I would be happy to share tissues with anyone who is interested.

Title: Pharmacological targeting of tissue remodeling and repair in the respiratory tract.

My current research interests are focused on mechanisms that regulate structural remodelling and repair of the airways and lung parenchyma in asthma and COPD. Identifying novel therapeutics for chronic lung disease is my long-term scientific goal. In this endeavour, I focus my work on the one hand on asthmatic airway remodeling, and in particular on the regulation of this pathological process by cholinergic receptors and the airway cholinergic system. Using in vivo and in vitro models the aim is to unravel the muscarinic receptor subtypes and signaling involved. Moreover, we are interested in the mechanisms that regulate plasticity of the airway neural network in asthma for which we recently established stem cell-derived airway cholinergic neurons. A second focus of my work is regenerative pharmacology of the distal lung in COPD and IPF. Here, my research interests are mainly centered around the function and dysfunction of distal lung stem cells/progenitors in health and disease. In particular, I am interested in understanding progenitor cell-niche interactions in disease as a potential background for the discovery of novel drug targets. In my presentation, I will shortly discuss both research lines and invite collaboration in each of these areas.
