Mechanizmy molekularne przekazywania sygnału aktywacji przez wybrane receptory błonowe płytek krwi

Abstract

This review paper concerns molecular mechanisms of signal transduction by various receptor systems and the role of various agonists in the activation of blood platelets. Authors present the physiological pathways leading to platelet activation and release reaction, as well as those responsible for the natural feedback inhibition of platelet activation. The significance of the conformational changes in platelet receptor glycoproteins, the reorganisation of platelet cytoskeleton, the mobilisation of calcium, processes of phosphorylation/déphosphorylation, and lipid bilayer fluidity in the modulation of the triggering of platelet signal transduction is discussed.
