Telomere Maintenance Peptides are a class of short-chain amino acids or peptide sequences specifically designed or naturally occurring to influence the activity of telomerase, the enzyme responsible for adding repetitive nucleotide sequences to the ends of chromosomes (telomeres). The clinical objective is to support the preservation of telomere length, thereby protecting genomic integrity and slowing the rate of cellular senescence. These agents are a focus area in longevity and cellular health research.
Origin
The concept is a direct application of Nobel Prize-winning research on telomeres and telomerase, linking chromosomal end-cap shortening to cellular aging. Maintenance highlights the goal of preserving existing telomere length, while peptides specifies the molecular class of the therapeutic agents used to modulate this process.
Mechanism
These peptides operate by either directly activating the telomerase enzyme or by modulating upstream signaling pathways that regulate telomerase expression and function within the cell nucleus. By preserving telomere length, the cell is protected from reaching the Hayflick limit prematurely, thus extending its replicative lifespan. This mechanism is crucial for maintaining the regenerative capacity of tissues and supporting overall hormonal organ health.
