Through mechanisms yet to be fully elucidated, VEGF orchestrates a cascade of events pivotal for vascular repair following ischemic insult, thereby fostering an environment conducive to neuronal survival and functional recovery (Yasuhara and Shingo 2004)
But the glucagon-driven metabolic improvements, including better lipid profiles, reduced inflammation markers, and improved insulin sensitivity, suggest benefits beyond what weight loss alone would explain

A comprehensive 2008 review of -MSH and related tripeptides in Endocrine Reviews situates KPV within the broader melanocortin anti-inflammatory literature and its potential in immune-mediated inflammatory disease
This activates protein kinase A (PKA), which phosphorylates and stabilizes MITF (microphthalmia-associated transcription factor), driving transcriptional upregulation of tyrosinase, TRP-1, and TRP-2rate-limiting enzymes in the eumelanin biosynthesis pathway (Abdel-Malek et al., Pigment Cell Research, 2001)
