WebFeb 12, 2024 · We recently discovered that global knock-out of the thrombin receptor, also known as Protease Activated Receptor 1 (PAR1), accelerates myelin development. Here we demonstrate that knocking out PAR1 also promotes myelin regeneration. Outcomes in two unique models of myelin injury and repair, that is lysolecithin or cuprizone-mediated ... WebApr 9, 2000 · PAR1 is a high-affinity thrombin receptor, and PAR4 is a low apparent affinity thrombin receptor of uncertain function. The goal of these studies is to determine the kinetics of thrombin activation of PAR1 and PAR4 and to relate the individual inputs from each receptor to platelet Ca 2+ signaling, secondary autocrine stimulation, and aggregation.

WebNov 8, 2013 · The proposed model for PAR1 or PAR3 enhancing PAR4 activation is that after cleavage of PAR1 or PAR3, thrombin remains bound to the hirudin-like sequence via exosite I and cleaves an adjacent PAR4. In addition to recruiting thrombin to the surface of cells, the exosite I interaction is likely holding thrombin in the protease conformation for ...
