  1. As a part of the big picture, I am interested in the immunological aspects of the regulation of inflammation. Inflammatory response can be viewed as a consequence of events when certain cell players act at a certain time. All events of the inflammation start with the trigger, which is known in some cases such as infection, or still unknown (e.g. most of autoimmune diseases). After trigger, initial damage of the tissue occurs followed by reaction of certain cell types within certain time frame. Platelets respond to damage within seconds, tissue resident macrophages within minutes, granulocytes within hours, peripheral macrophages within days, T and B cells within weeks, and memory T cells and antibodies can persists for years. My research focuses on a very early events of inflammation. Particularly I am interested in the role of tissue resident macrophages (microglia) in the regulation of autoimmune inflammation in the central nervous system (CNS) and the role of platelets in teh initiation of inflammatory response in the CNS.
  2. The role of microRNAs in adaptation of macrophages and microglia to CNS microenvironment.
  3. The role of brain-specific glycolipids in lipid rafts of astrocytes and neurons in the regulation of CNS inflammation.
  4. The role of platelet-lipid raft interactions in the regulation of neuroinflammation, neurodegeneration and development.
