Department of Cytology is primarily interested in the effects of cerebral ischemia on neural and synaptic plasticity in the mammalian hippocampus. Various kinds of experimental model systems used (dissociated and organotypic cultures and in vivo models) allow us to study different aspects of synaptic remodeling, which is likely to be associated with ischemia-induced changes in neurons. The contacts is highly experienced in light and electron microscopy, including ultrastructural analysis, histochemistry, immunohistochemistry (including gold-immunolabeling), computer-assisted morphometry, and 3-dimensional (3D) reconstruction. The Department is equipped with electron microscopes (Jeol 1010 and Selmi TEM100M) and light microscopes, and has sufficient facilities for cell and slice culturing and in vivo experiments. The Department pioneered the neural tissue culturing in Ukraine, and we have good experience of using various tests to estimate cell viability in the cultures. We particularly focus on quantitative analysis of morphological correlates of synaptic plasticity in normal and pathological development. Computer programs for image analysis and morphometry, both commercial (Bioquant image analysis system) and developed in the Department can be adapted to new tasks as needed.

Science Department of Cytology aims to study the molecular and cellular mechanisms of nervous tissue damage arising from the development of neurodegenerative diseases (cerebral ischemia, Alzheimer's disease, Parkinson's disease) or accompanying pathological states (perinatal pathology of the central nervous system, brain injury, stress, exocrine pancreatic failure), and study approaches to the prevention and correction of neurodegenerative processes. An important part of research is testing pharmacological agents to identify their neuroprotective properties. Started studying the possibilities of using embryonic nervous tissue and stem cells to correct neurodegenerative processes caused by cerebral ischemia.

[[File:Synapsys.jpg|300px|thumb|Types of synapses red arrow - simple, yellow - perforated, green - multiple]] Scientists department found that short-term cerebral ischemia in model systems (in vitro and in vivo) causes the development of destructive changes of neurons and synaptic reorganization of staff in CA1 area of the hippocampus - a brain structure that is responsible for the processes of memory formation and learning and is highly sensitive to lack of oxygen and glucose. When using light and electron microscopy were investigated structural characteristics of delayed neuronal death of hippocampal CA1 area in ischemic effects of varying duration and period of reperfusion. Established in early periods of ischemic damage occurs synaptic remodeling apparatus, namely changing the spatial distribution of synaptic vesicles at presynaptic terminals, increasing the thickness and density of postsynaptic podovzhenist, changing the ratio of types of synaptic terminals upwards and multiple perforated significantly increased volume astrohlialnyh processes and their contact area of pre- and postsynaptic elements synapses. These data suggest that ischemic effect induces synaptic plastic adjustment device, and a clear correlation between changes in structural elements confirms the concept of "tripartite synapse", according to which astrohliyiyi processes that envelop the synapse, the third functional component with presynaptic and postsynaptic bud terminallyu.

It was discovered structural and functional connection between the manifestations of destructive changes of neurons and glial reactivity level cells (microglia hyperplasia and hypertrophy of astrocytes) in ischemic hippocampal impact.

[[File:Hippocamp.jpg|250px|thumb|Three-dimensional reconstruction to study synaptic plasticity of hippocampal neurons and glial response to ischemic lesions|left]] In the model of cultured hippocampal slices was shown that a shortage of oxygen and glucose pyramidal neurons of the hippocampus CA1 area are the most vulnerable. Intercalary, astrohlialni and microglial cells compared were more resistant to oxygen-glucose derivation (SRM), moreover, their activation is observed, indicating the potential for interneurons and glia modulate pyramidal neurons function and affect the functioning of the system. Shows the change in the level of expression of subunits HIF-1α, HIF-3α, SERCA2b and PMCA1-2 in neurons and CA1 hippocampal area SA3 in response to holding SRM and anoksychnoho prekondytsionuvannya and reduce the number of damaged cells in both areas of the hippocampus with a stabilization of HIF-1.

It developed an original computer program image analysis using simulation in which cerebral ischemia in vivo and in vitro was investigated synaptic changes in the spatial distribution of vesicles in the terminal area CA1 of the hippocampus. It is shown that after an ischemic episode spatial cluster formed vesicles become more diffuse, and most organelles were removed from the active zone of the synapse.
 +
In the study of correction of ischemic brain damage data were obtained regarding the neuroprotective action of aromatic amino acids, FGL - peptide mimetics NCAM, bioflavonoids, including Corvitin. In terms of experimental cerebral ischemia was found neuroprotective effect of hypoxic pre- and postkondytsionuvannya the state CA1 area of the hippocampus.

It was found dependent morphological and functional state of neurons of the hippocampus of exocrine pancreatic function and the data on the possibility of correcting pancreatic encephalopathy using enzyme replacement therapy.

[[File:Stemcell.jpg|300px|thumb|The integration of stem cells in the nervous tissue in ischemic damage]] In model systems in vivo and in vitro study was conducted regenerative potential of stem cells of different origins in ischemic lesions. It is shown that stem cells transplanted after experimental ischemic impact in both models are able to survive in the long term the recipient tissue, differentiate into mature neurons as well as in cells astrohliyi, and integrate into the fabric of the recipient. Established that stereotactic transplantation neural progenitor cells promotes restoration of spatial memory in animals after ischemic brain damage.

When the clinic in patients with ischemic stroke frequency of allelic polymorphism studied genes encoding subunits of constitutional and imunoproteasom. When played ischemic stroke in vivo measurements were performed three types of proteolytic activity of the proteasome (trypsynopodibna, himotrypsynopodibna and peptydhlutamil peptydhidrolazna) in the brain tissue of rats. These data suggest proteasome dysfunction in conditions of ischemic stroke.
