The protease-activated receptors (PARs) play a pivotal role in inflammatory and nociceptive processes. PARs
have raised considerable interest because of their capacity to regulate numerous aspects of viscera physiology and
pathophysiology. The present article summarizes research on PARs and proteases as signalling molecules in visceral pain.
In particular, experiments in animal models suggest that PAR2 is important for visceral hypersensitivity. Moreover,
endogenous PAR2 agonists seem to be released by colonic tissue of patients suffering from irritable bowel syndrome,
suggesting a role for this receptor in visceral pain perception. Thus, PARs, together with proteases that activate them,
represent exciting targets for therapeutic intervention on visceral pain.
