Research advances of PAR-2 and gastrointestinal motility / 医学研究生学报

ABSTRACT

Proteinase activation receptor-2 (PAR-2) is one of the G protein coupling receptor family members.It exists in all over the epithelial cell surface of gastrointestinal tract,and is easy to expose to the proteinase that can activate it.It is a direct exocrine regulator of many digestive glands,and directly affects the capability of gastrointestinal tract.At present,the PAR-2's unique activation way,its wide distribution in digestive system and its complicated physiological functions,especially the relation between PAR-2 and the gastrointestinal movement and perception,are being highly concerned.
