Peptide Signalling Pathways

Meaning

Peptide Signalling Pathways are the intricate cellular communication networks mediated by short chains of amino acids (peptides) that act as ligands to initiate specific biological responses in target cells. These pathways are crucial modulators of virtually every physiological process, including growth, metabolism, immunity, and tissue repair, often acting as fine-tuning agents for the larger endocrine system. In the longevity and hormonal health domain, these peptides, such as Growth Hormone Releasing Hormone (GHRH) or various gut-derived peptides, represent powerful tools for tissue regeneration and metabolic optimization. They are key components of the body’s intrinsic repair and maintenance system.
