Joca Lab - Translational Neuropharmacology

How pscyhoactive drugs affect our brain to regulate mood, motivation and cognitive aspects associated with stress-related psychiatric disorders (e.g. depression and anxiety)? How can we use this information to understand disease neurobiology and foster the development of improved therapeutic for mental disorders?

These are some of the questions that our group is trying to answer. Our research focus is the mechanism of action of psychoactive drugs, primarly antidepressants, examining how these unique molecules influence neural plasticity, stress responses, and emotional regulation. We are particularly interested in understanding how lipid mediators, such as endocannabinoids, affect neuroplasticity and behavior.

We use translational approaches combining animal models of stress-related psychiatric disorders, in vitro models for drug testing (primary and immortalized cell cultures), molecular biology methods for protein and mRNA quantification, evaluation of drug-receptor interactions, neurochemical analysis (neurotransmitters and lipid mediators), and microscopy (immunofluorescence, confocal). We collaborate with different groups at Aarhus University and abroad to tackle our research questions with different methodological approaches and perspectives.
