Figure 4From: The bradykinin BK2 receptor mediates angiotensin II receptor type 2 stimulated rat duodenal mucosal alkaline secretionHypothetical depiction of mechanisms involved in CGP42112A-stimulated alkaline secretion. Hypothetical depiction of mechanisms involved in CGP42112A-stimulated alkaline secretion. Black arrows indicate alkaline secretions from crypts and the villi (#1-Flemstrom [1]). Red and blue arrows indicate precapillary and postcapillary blood flow, respectively (#2 – Jodal et al [29]). Green area indicates the location of iNOS protein involved in acid-induced alkaline secretion by the villus epithelium (#3 -Holm et al [9, 18]). The location of AT2 receptors is indicated by dotted area (#4 -Johansson et al [3]). Orange areas indicate the location of BK2 receptors (#5 – Ewert et al, present study).Back to article page
