Molecular Signaling Peptides

Meaning

Molecular Signaling Peptides are short chains of amino acids that function as highly specific biological messengers, binding to cell surface receptors or entering the cell to regulate diverse physiological processes. Unlike classical hormones, these peptides often exhibit pleiotropic effects, coordinating complex cellular behaviors such as cell proliferation, differentiation, tissue repair, and immune modulation. Their precise and potent action makes them critical components of the body’s internal communication network.
