Calcitonin Gene Related Peptide (CGRP) (83-119), rat (TFA) is a 37 amino acid calcitonin family of neuropeptide, acts through calcitonin receptor-like receptor (CRLR). IC50 & Target: CRLR^[1]. In Vitro: Calcitonin Gene Related Peptide (CGRP) (83-119), rat (TFA) belongs to the calcitonin family of neuropeptides which also includes adrenomedullin, amylin, calcitonin, intermedin and calcitonin receptor-stimulating peptide. Calcitonin Gene Related Peptide (CGRP) has two isoforms (alphaCGRP and betaCGRP), and acts through calcitonin receptor-like receptor (CRLR)^[1]. Calcitonin Gene Related Peptide (CGRP) plays a key role in migraine pathophysiology and is associated with activation of the trigeminovascular system. CGRP prossibly acts postjunctionally in these areas putatively involved in primary headaches^[2]. In Vivo: Calcitonin Gene Related Peptide (CGRP) (83-119), rat (TFA) is a potent inducer of oedema in rat orofacial tissue. CGRP (100 uL; 8-33 pM) induces a rapidly developing (5-15?min) and long-lasting (6?h), dose-dependent oedema in the rat cheek. CGRP induces a smaller oedematogenic effect in the rat hind paw also blocked by the CGRP antagonist. CGRP (16 pM) potentiates the oedema induced by co-injected substance P (3.7 nM)^[3].
