Description

Vasoactive Intestinal Peptide represents a naturally occurring 28-amino acid neuropeptide with diverse physiological functions including vasodilation, neurotransmission, and regulation of various organ systems. The compound demonstrates activity at VIP receptors (VPAC1 and VPAC2) and related receptors, leading to activation of adenylyl cyclase and increased cyclic adenosine monophosphate (cAMP) levels. VIP functions as both a neurotransmitter and hormone, with widespread distribution throughout the nervous system and peripheral tissues. The peptide demonstrates multiple biological activities including vasodilation, bronchodilation, regulation of gastrointestinal function, and modulation of immune responses. Research applications include investigation of neuropeptide signaling mechanisms, cardiovascular regulation, gastrointestinal physiology, respiratory function, and the role of VIP in various neurological and physiological processes.
