Cellular Signaling Peptides

Meaning

Cellular Signaling Peptides are short chains of amino acids that function as critical communication molecules, facilitating precise information transfer between cells, tissues, and organs. In endocrinology, these peptides act as ligands, binding to specific cell surface receptors to initiate a cascade of intracellular events. They regulate fundamental processes such as growth, metabolism, immune response, and the secretion of other hormones, serving as essential components for maintaining physiological homeostasis.
