Protease-activated receptors and itch.
Protease-activated receptors (PARs) have been implicated in a variety of physiological functions, as well as somatosensation and particularly itch and pain. Considerable attention has focused on PARs following the finding they are upregulated in the skin of atopic dermatitis patients. The present review focuses on recent studies showing that PARs are critically involved in itch and sensitizatio...
متن کاملProtease-activated receptors in hemostasis.
Protease signaling in cells elicits multiple physiologically important responses via protease-activated receptors (PARs). There are 4 members of this family of G-protein-coupled receptors (PAR1-4). PARs are activated by proteolysis of the N terminus to reveal a tethered ligand. The rate-limiting step of PAR signaling is determined by the efficiency of proteolysis of the N terminus, which is reg...
متن کاملProtease-activated receptors and inflammatory hyperalgesia.
Recent advances in basic science pointed to a role for proteinases, through the activation of proteinase-activated receptors (PARs) in nociceptive mechanisms. Activation of PAR1, PAR2 and PAR4 either by proteinases or by selective agonists causes inflammation inducing most of the cardinal signs of inflammation: swelling, redness, and pain. Sub-inflammatory doses of PAR2 agonist still induced hy...
متن کاملRho: theme and variations
In addition to their roles in organizing the actin cytoskeleton, members of the Rho family of GTP-binding proteins have recently been implicated in a plethora of other functions, including the activation of kinase cascades and transcription factors, and the control of endocytosis and secretion. Alongside this expansion is proposed functions has been the identification of multiple target protein...
متن کاملProtease-activated receptors in cardiovascular diseases.
Thrombosis associated with the pathophysiological activation of platelets and vascular cells has brought thrombin and its receptors to the forefront of cardiovascular medicine. Thrombin signaling through the protease-activated receptors (PARs) has been shown to influence a wide range of physiological responses including platelet activation, intimal hyperplasia, inflammation, and maintenance of ...
