Autocrine Signaling Peptides

Meaning

Autocrine Signaling Peptides are a class of regulatory molecules, typically small protein fragments, secreted by a cell that subsequently bind to specific receptors located on the surface of that same originating cell. This mode of localized communication allows the individual cell to self-regulate its own function, including its rate of proliferation, differentiation, or programmed cell death. These self-directed signals are fundamentally important in processes requiring precise local control, such as immune response modulation and the initial stages of tissue repair.
