Research Comparison
MOTS-c vs VIP (Vasoactive Intestinal Peptide)
A side-by-side research comparison of MOTS-c and VIP (Vasoactive Intestinal Peptide) drawn from Cobalt Peptides' peptide database records.
MOTS-c
MOTS-c (Mitochondrial Open Reading Frame of the 12S rRNA-c) is a 16-amino acid mitochondrial-derived peptide encoded by mitochondrial DNA. It functions as a mitohormone, regulating metabolic homeostasis, insulin sensitivity, and cellular stress responses. Unlike nuclear-encoded peptides, MOTS-c is produced within mitochondria and can translocate to the nucleus under metabolic stress, where it influences gene expression. Its primary activity involves activation of the AMPK pathway via the folate-AICAR axis, making it a key regulator of energy metabolism and mitochondrial function.
VIP (Vasoactive Intestinal Peptide)
Vasoactive Intestinal Peptide (VIP) is a 28-amino acid neuropeptide with potent anti-inflammatory, immunomodulatory, and neuroprotective properties. Acting through VPAC1 and VPAC2 receptors, VIP regulates immune function, vascular tone, circadian rhythms, and neurological activity. VIP has been extensively studied in inflammatory, pulmonary, and neurological conditions. Intranasal delivery enables direct CNS access via olfactory and trigeminal pathways, while systemic administration influences immune and vascular systems. It is particularly notable in research involving chronic inflammatory response syndrome (CIRS), respiratory dysfunction, and neuroimmune regulation.
