Research Interests

We are focusing our research interests on the investigation of the molecular mechanisms that neurotrophic factors and their receptors are using to regulate the regenerative capacity of the adult nervous system. Neurotrophins, control brain development and maintenance during adulthood and in aging, while they importantly participate in neuronal survival, differentiation and repair. Our studies are ranging from neurotrophin receptors’ signaling to adult hippocampal neurogenesis to development of novel ligands with specific effects on these receptors (mainly the Trks and p75NTR receptors) and their therapeutic potential on animal models of neurodegenerative diseases (Alzheimer’s Disease).

Research Interests

Translational research in psychiatry with a focus on developing and exploring valid translational paradigms in humans for research in the psychoses, affective processing in mood disorders, anxiety and arousal. We study (endo)phenotypes such as the prepulse inhibition of the acoustic startle response, aspects of cognition and the modulation of startle and the pupillary light reflexes by affective states, threat, and arousal. We investigate the genetic architecture of these phenotypes, their association with cognitive functions, personality dimensions and their response to pharmacological and psychological interventions in healthy subjects, high risk populations and patients. The central aim is to characterize these phenotypes, in the belief that learning about them will inform us on core pathophysiological dimensions and the neurobiology of psychosis and anxiety. We hope that this will aid psychiatric diagnosis, facilitate the development of customized treatments and ultimately improve patient care. A large part of this work is focused on the neurobiology and genetics of schizophrenia-spectrum disorders.

Research Interests

Axoglial interactions during myelination
: Our work focuses on a) elucidating axoglial interactions in the juxtaparanodal regions of myelinated fibers in health and demyelinating pathologies b) utilizing models of demyelination/remyelination in vivo and in vitro to test molecules that may influence these processes c) investigating the role of autophagy in CNS myelin homeostasis.
Neuronal migration and cortical interneuron development and function: Cortical Interneurons control the balance of excitation and inhibition and are implicated in  neurodevelopmental pathologies (epilepsy, autism, schizophrenia, bipolar disorder). We are studying the molecular, cellular and functional changes of cortical interneurons in two mouse models of decreased inhibition that we have generated due to the ablation of the small RhoGTPases Rac1 and 3.
