PLATELET IMMUNOLOGY & FUNCTION

Blood platelets are small anucleated cells with a variety of functions in hemostasis, inflammation and immunity. Platelets interact with neutrophils and monocytes, thereby, promoting different mechanisms of the innate immune response such as extravasation, phagocytosis, NETosis, oxidative burst and release of various inflammatory cytokines and enzymes. As a consequence platelets get activated via different signaling pathways and release soluble factors (cytokines, chemokines, growth factors) stored in granules. For a better understanding of the molecular mechanisms our current research is focused on the characterization of different receptors involved in platelet adhesion and activation including P-selectin, ADP receptor (P2Y12), thromboxane A2 receptor (TBXA2R) and C-type lectin-like receptor 2 (CLEC-2).

Receptors and molecules that mediate platelet interaction with leukocytes and endothelial cells. Our research is focused on P-selectin/PSGL-1 and CLEC-2/PDPN.
