Endogenous Signaling Pathways

Meaning

Endogenous Signaling Pathways represent the complex, intrinsic communication networks within a cell that transmit information from the cell surface to the nucleus or other intracellular targets. These pathways are activated by native, or endogenous, molecules such as hormones, growth factors, and neurotransmitters, governing all cellular activities. They are the fundamental machinery that dictates cell fate, metabolism, and proliferation.
