Peptides Molecular Signaling

Meaning

Peptides Molecular Signaling refers to the vast, complex network of cellular communication mediated by short chains of amino acids, known as peptides, which act as highly specific regulatory molecules. Unlike classical hormones, peptides often exhibit paracrine or autocrine effects, acting locally on adjacent cells or the cell that secreted them, in addition to systemic endocrine functions. This signaling is critical for modulating a wide array of processes, including inflammation, appetite, tissue repair, and neuroprotection. The precise action of these peptides is central to regenerative and longevity medicine.
