- Role tissue transglutaminase (TG-2) in neuronal physiology and pathology.
- Retinoic acid-induced neurogenesis.
- The Ca2+ and cAMP-signaling interplay in determination of neuronal fate, outgrowth and in acute and persistent stress.
- Neuronal homeostasis and plasticity in response to acute injury (e.g. brain injury, stroke, epilepsy), and in neurodegeneration (e.g. HD, PD) and in psychiatric conditions (e.g. depression).
Primary in my research, I am interested in the role of TG-2 in determination of neuronal fate, neurogenesis, maturation and regeneration of neurons, and in theirs response to pathological conditions (e.g. excitotoxicity). Secondly, because Ca2+ and cAMP-signaling play a prominent role in above processes and TG-2 is known modulate or to be modulated by Ca2+ and cAMP-signaling, I am interested in a relationship between TG-2, and Ca2+/cAMP-signaling in neurons and cells destined to become neurons, especially during response of CNS neurons to acute and persistent stress. In my study, I use transgenic and knock-out mouse models, acute mouse brain slices, mouse neuronal cell culture and culture of neuronal-like human neuroblastoma SH-SY5Y cells.
In future, I intend, by using the mouse models, to investigate how RA, TG-2, Ca2+, cAMP-signaling molecules and signaling pathways are engaged in plasticity and in stress response of young and adult neurons in neurological (e.g. epilepsy) and psychiatric conditions such as major depression, bipolar disorder and schizophrenia.
