Humanin was identified during a search for factors that protected cells from Alzheimer-related laboratory insults. That discovery opened a new research direction. Later work examined interactions with Bax, a protein involved in programmed cell death. Humanin is also linked to a short sequence within mitochondrial DNA. The biology is more complicated than a mitochondrial anti-ageing switch. Related nuclear sequences and the source of the peptide have also been investigated. Protecting cultured cells does not demonstrate prevention of dementia or longer human life. Keep humanin’s experimental promise separate from clinical claims that require direct testing in people.
