Cardiovascular responses mediated by protease-activated receptor-2 (PAR-2) and thrombin receptor (PAR-1) are distinguished in mice deficient in PAR-2 or PAR-1.
We developed mice deficient in protease-activated receptor-2 (PAR-2) or PAR-1 to explore the pathophysiological functions of these receptors. In this report, we evaluated mean arterial pressure and heart rate (HR) changes in response to PAR-1 or PAR-2 activation in anesthetized wild-type (WT), PAR-1-deficient (PAR-1(-/-)), and PAR-2-deficient (PAR-2(-/-)) mice. In WT mice, TFLLRNPNDK, a PAR-1 s...
متن کاملProtease-activated receptor (PAR)-2 is required for PAR-1 signalling in pulmonary fibrosis
Idiopathic pulmonary fibrosis is the most devastating diffuse fibrosing lung disease of unknown aetiology. Compelling evidence suggests that both protease-activated receptor (PAR)-1 and PAR-2 participate in the development of pulmonary fibrosis. Previous studies have shown that bleomycin-induced lung fibrosis is diminished in both PAR-1 and PAR-2 deficient mice. We thus have been suggested that...
متن کاملProtease-activated receptor-2 (PAR-2)-related peptides induce tear secretion in rats: involvement of PAR-2 and non-PAR-2 mechanisms.
Protease-activated receptor-2 (PAR-2) plays an extensive role in the regulation of digestive exocrine secretion. The present study examined whether PAR-2-related peptides could modulate tear secretion in rats and analyzed the underlying mechanisms. SLIGRL-NH(2), a PAR-2-activating peptide (PAR-2-AP) derived from mouse/rat PAR-2, when administered i.v. in combination with amastatin, an aminopept...
متن کاملExpression of protease activated receptor-2 (PAR-2) in central airways of smokers and non-smokers.
BACKGROUND Protease activated receptor-2 (PAR-2) is a transmembrane G protein coupled receptor preferentially activated by trypsin and tryptase. The protease activated receptors play an important role in most components of injury responses including cell proliferation, migration, matrix remodelling, and inflammation. Cigarette smoking causes an inflammatory process in the central airways, perip...
متن کاملDifferential expression of functional protease-activated receptor-2 (PAR-2) in human vascular smooth muscle cells.
The protease-activated family of G protein-coupled receptors includes PAR-1 and PAR-3, which are activated by thrombin, and PAR-2, which is activated by trypsin and tryptase. PAR-2 has recently been shown to be expressed in human endothelial cells. In the present studies, we have examined the expression of PAR-2 in other cells, particularly vascular smooth muscle, and tested whether the recepto...
