Impact of treatment with melatonin on cerebral circulation in old rats.

abstract：BACKGROUND AND PURPOSE:Proteinase activated receptor 2 (PAR2) is a GPCR associated with inflammation, metabolism and disease. Clues to understanding how to block PAR2 signalling associated with disease without inhibiting PAR2 activation in normal physiology could be provided by studies of biased signalling. EXPERIMENT...
