Mitochondrial-Derived Peptides: Implication in the Therapy of Neurodegenerative Diseases.

Mitochondrial-derived peptides (MDPs), including humanin, MOTS-c, and small humanin-like peptides (SHLPs), have emerged as promising therapeutic candidates for neurodegenerative diseases such as Alzheimer's disease (AD), Parkinson's disease (PD), and Huntington's disease (HD). This review systematically evaluates current literature retrieved from databases including PubMed, Scopus, and Web of Science using keywords such as "mitochondrial-derived peptides," "neurodegeneration," "humanin," "MOTS-c," and "SHLPs." Studies were included based on their relevance to mitochondrial function, oxidative stress, neuroprotection, and anti-inflammatory mechanisms in AD, PD, and HD models.
