['Calcitonin gene-related peptide (CGRP) is thought be involved in the modulation of intestinal motility. CGRP receptor is composed of receptor activity-modifying protein (RAMP) 1 combined with calcitonin receptor-like receptor (CRLR) for CGRP. We investigated the role of CGRP in mice with experimentally induced colitis.', 'We used dextran sodium sulfate (DSS) to induce colitis in mice. We compared the severity of colitis in wild-type (WT) mice, mice treated with a CGRP receptor antagonist (CGRP', 'The severity of inflammation in DSS-induced colitis increased markedly in CGRP'] Does rAMP1 suppress mucosal injury from dextran sodium sulfate-induced colitis in mice?
