All major coagulation reactions do not occurs in blood plasma itself, these processes are actually two-dimensional reactions localized to thephospholipid membranes. Almost all blood cells, lipoproteins, and microparticles provide assembly of protein complexes. A central role among them are played by platelets and platelet-derived microparticles. On their membranes occurs the most important coagulation reactions such as activation of prothrombin by prothrombin complex, activation of factor X by complexes intrinsic and extrinsic tenase. This reactions are important for processes activation of the contact path coagulation, activation factor XI by thrombin, appearance of enzymatic activity of factor VIIa etc. This review is focused on the membrane-dependent reactions, here are discussed mechanisms and regulation these reactions and the possible prospects of the study.
