α-CGRP (mouse, rat)  (Synonyms: CGRP (83-119), mouse, rat)

α-CGRP (mouse, rat), a neuropeptide (calcitonin gene-related peptide (CGRP)) mainly expressed in neuromuscular junction, is a potent vasodilator. α-CGRP (mouse, rat) can lead to a fall in blood pressure and an increase in heart rate by peripheral administration, also relax colonie smooth muscle. α-CGRP (mouse, rat) has the potential in cardiovascular, pro-inflammatory, migraine and metabolic studies^[1][2][3][4].

α-CGRP (mouse, rat) can regulate the innate lymphoid cell response in 2 groups^[1].
α-CGRP (mouse, rat) regulates insulin secretion and reduces the risk of type 2 diabetes^[2].

α-CGRP (mouse, rat) (0.25, 0.5, 1 μg/kg/min, intravenous) dose-dependent decreases mean arterial blood pressure, while heart rate and systemic vascular conduction increased, while cardiac output remained unchanged^[3].
α-CGRP (mouse, rat) plays an important role in the regulation of Kainic acid (KA) induced pyramid-cell death in hippocampal CA3 region^[4].
