Vasoactive Intestinal Peptide (VIP) is a 28–amino acid neuropeptide. It is found across different biological systems and cellular environments. In research settings, it is mainly examined for how it interacts with specific peptide receptors and participates in intracellular signaling processes.

More specifically, studies look at VIP as a ligand in receptor-mediated pathways. This is particularly associated with cyclic adenosine monophosphate (cAMP) signaling. Because of its structure, it has been shown to bind to class B G protein-coupled receptors, particularly VPAC1 and VPAC2. This way, it continues to be explored in molecular signaling research.

Working Mechanism of Vasoactive Intestinal Peptide

Vasoactive Intestinal Peptide is primarily studied for how it engages with receptor systems and initiates intracellular signaling cascades. These are explored in controlled environments to better understand peptide-receptor interactions at the molecular level. Moreover:

• It has been shown to interact with VPAC1 and VPAC2 receptors, both part of the G protein-coupled receptor (GPCR) family
• VIP has been studied to activate adenylate cyclase following receptor binding, leading to increased intracellular cAMP levels in experimental models.
• Studies suggest activation of protein kinase A (PKA)-dependent signaling pathways downstream of cAMP production.
• It has been studied for its role in modulating ion channel activity and intracellular calcium signaling through secondary messengers
• It has been associated with transcription-related pathways via cAMP response element-binding protein (CREB) signaling
