“…Kokkotou et al [35] recently reported that CRFR2-null mice developed reduced the severity of intestinal inflammation following luminal exposure to Clostridium difficile toxin A, and this effect was recapitulated by pretreatment with astressin 2B, suggesting the mediation of inflammatory responses by CRF/CRFR2. We also observed recently that Ucn I aggravated the intestinal ulcerogenic response to ischemia/reperfusion, together with an increase of MPO activity, in an astressin 2B-inhibitable manner [51]. Thus, it is possible that CRF might worsen the tissue injury via the CRFR2, if the motility does not play any role in the pathogenic mechanism.…”
