WebJul 1, 1998 · Previous studies demonstrate that both 5-hydroxytryptamine (5-HT) and cyclic AMP (cAMP) induce chloride efflux from crypt colonocytes in the rat distal colon; antagonist studies suggest that the 5-HT response is mediated primarily by the 5-HT4 receptor. Since this receptor is known to be positively coupled to adenylate cyclase, we postulated ... WebDec 1, 2024 · The columns represent keratin distribution on the crypt bottom to crypt top axis, and the thickness of each column represents the relative amount of each keratin in the crypt. Striped columns indicate less studied keratins, for which the actual expression pattern in crypts still needs to be confirmed.
