- Humanin(Mitochondrial peptide)· Mitochondrial Health & Energy
- Humanin is one of the most fascinating peptides in biology — a tiny molecule encoded inside your mitochondria that appears to protect cells from many kinds of stress, especially in the brain. Levels of Humanin decline with age, and people with higher Humanin tend to have better metabolic and cognitive markers. It is a frequent topic in longevity research alongside MOTS-c and NAD+.
What is it?
Humanin is a 24-amino-acid mitochondrial-derived peptide encoded within the mitochondrial 16S rRNA gene. It was discovered in 2001 by researchers searching for endogenous factors that protect neurons from Alzheimer's-related toxicity. Humanin is one of the first identified mitochondrial-derived peptides (MDPs), a class that also includes MOTS-c and the SHLPs. It is studied for neuroprotection, metabolic health, and longevity, and is sold strictly for laboratory research.
In plain English
Humanin is one of the most fascinating peptides in biology — a tiny molecule encoded inside your mitochondria that appears to protect cells from many kinds of stress, especially in the brain. Levels of Humanin decline with age, and people with higher Humanin tend to have better metabolic and cognitive markers. It is a frequent topic in longevity research alongside MOTS-c and NAD+.
How it works
Humanin binds a heterotrimeric receptor complex (CNTFR/WSX-1/gp130) and engages another receptor (FPR2) on target cells. It activates STAT3 signaling, suppresses apoptosis under stress, improves insulin sensitivity, and protects neurons from amyloid-beta toxicity in Alzheimer's models. It is considered a key 'cellular survival' signal sent from mitochondria to the rest of the body.
