MetadataShow full item record
P-selectin is stored in the a granules of blood platelets. Following platelet activation by different agonists, P-selectin is expressed on the cell surface where it mediates adhesion primarily to leucocytes.The aim of the study was to evaluate the direct effect of Proteus mirabilis lipopolysaccharides on the P-selectin expression on the platelet surface measured by cytometric method. The obtained results showed that LPS in vitro induced the expression of P-selectin (CD62) on platelets. It indicates that endotoxin from Gram-negative bacteria can activate blood platelets.
