Department of Cytology

Prof. Galyna Skibo

Department of Cytology has been established in 1996 based on the Laboratory of Neurocytology. Its organizer and the only chair until nowadays is [G.G.Skibo|Prof. Galyna Skibo], the corresponding member of NAS of Ukraine, laureate of State Prize of Ukraine in sciences and engineering, Bogomoletz and Kostiuk Prizes of NAS of Ukraine.

Our research

The research activity of the Department of Cytology is focused on the study of cellular and molecular mechanisms of neurodegeneration in different parts of the nervous system and the search for neuroprotective approaches. The current research topics of the Department are:

• genetically determined molecular mechanisms of intercellular and intracellular signaling in norm and pathology in vitro (brain ischemia, Alzheimer’s disease)
• molecular and cellular mechanisms of endogenous neuroprotection in the models of neurodegenerative diseases in vivo and in vitro (brain ischemia)
• regenerative properties of different origin stem cells and peculiarities of their application at experimentally induced neurodegenerative pathologies in vivo (brain ischemia, perinatal CNS pathology, neuroinflammation)
• development of biosafety criteria for stem cell cultivation
• cell mechanisms driving brain tissue degeneration in the rotenone model of Parkinson's disease
• dependence of structural and functional features of the brain on the function of the gastrointestinal tract (metabolic syndrome, exocrine pancreatic insufficiency) in vivo and in vitro
• effect of substances with antioxidant properties on the nervous tissue recovery of experimental animals during the brain ischemia-reperfusion
