Humanin (HN) is a 24-amino acid mitochondrial-derived peptide (MDP) that plays a critical role in cytoprotection, reducing inflammation, and regulating metabolic homeostasis.
Primarily discovered in 2001 in Alzheimer’s patients, it offers significant neuroprotective and anti-apoptotic effects.
Humanin shows therapeutic potential in age-related diseases, including Alzheimer’s, Parkinson’s, and diabetes, often by enhancing mitochondrial function.
Biological Role
Discovered in 2001, Humanin acts as a cytoprotective factor that suppresses neuronal cell death induced by Alzheimer’s-related insults, such as amyloid-beta (Aβ) peptides. It functions by:
- Inhibiting Bax-dependent apoptosis by preventing Bax from translocating to the mitochondria.
- Binding to cell surface receptors, including the trimeric receptor (CNTFR/WSX-1/gp130) and Formyl Peptide Receptor 2 (FPR2).
- Improving metabolic health and insulin sensitivity in animal models.
