Neuropeptide Receptors

Meaning

Neuropeptide Receptors are specialized protein structures embedded in the cell membranes of neurons and other peripheral cell types that specifically bind to neuropeptides, which are small, protein-like molecules used by neurons for intercellular communication. These receptors mediate the profound, long-lasting, and modulatory effects of neuropeptides on complex physiological functions, including mood, stress response, appetite regulation, and pituitary hormone release. Their function is crucial in the neuroendocrine system, acting as the final biological switch that translates a signaling molecule’s presence into a sustained cellular action, thereby governing complex behaviors and emotional states.
