Kisspeptin‑10 (KP‑10) is a short, bioactive cleavage product of the KiSS1 precursor peptide that has gained prominence as a central regulator of neuroendocrine systems. While originally linked to pubertal onset and regulation of the reproductive axis, emerging research suggests that KP-10 may have broader roles across multiple domains, including neuroprotection, hormonal regulation, and support for behavioral and affective processing.
