[Morphofunctional and molecular bases of pineal gland aging].
Editor's note
This narrative review surveys how the pineal gland changes with age — its morphology, molecular biology, and function — and how those changes might be corrected. The authors note that the pineal's functional activity declines with age, altering melatonin levels, even though the gland shows no marked structural atrophy. They summarise long-running work reporting that the pineal extract epithalamin and its synthetic tetrapeptide epithalon (epitalon) were associated with restored melatonin secretion and broad regulatory activity across neuroimmunoendocrine and antioxidant systems. As a review from the research lineage that originated these peptides, it is a synthesis of that group's own body of work rather than an independent appraisal, and its claims inherit the methodological limits of the underlying preclinical and translation-limited human literature. It is useful for orientation to epitalon's proposed pineal role. Independent replication and rigorous human data are needed before clinical conclusions can be drawn.
Plain-language abstract
This is a review article summarising how the pineal gland — a small brain structure that helps regulate sleep, hormones, and the body's clock — changes as we age, and how those changes might be addressed. The authors explain that the pineal gland's activity drops with age, which changes melatonin levels, even though the gland itself does not shrink dramatically. They summarise many years of research reporting that a pineal extract called epithalamin and its synthetic peptide version, epithalon (epitalon), were linked to restored melatonin production and to broad regulatory effects on the nervous, immune, hormone, and antioxidant systems. Because this review comes from the same research group that developed these peptides, it mainly reflects that group's own findings. It does not report a new controlled trial or side-effect data, and its conclusions would need confirmation by independent human studies.
