WebIn healthy colonic environment, epithelial cells from the top of crypts metabolize specifically butyrate (but not acetate, propionate) through Acyl-CoA Dehydrogenase (ACADs) leading to reduced levels of butyrate at the bottom of crypt. WebJan 5, 2024 · Transcriptomic signatures from adult cell populations, such as crypt top colonocytes and myofibroblasts, also localized to appropriate anatomical locations (Figure 2B). Furthermore, individual gene expression aligned with morphology; RET showed spot-specific expression at myenteric plexuses and PTPRC (CD45) at submucosal lymphoid …

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 ...
