receptor
n. countablen. a special part of a cell or a nerve ending that catches signals. It reacts to things like light, heat, or chemicals so your body can respond to them.
n. a protein molecule or specialized cell surface structure that binds to a specific signaling molecule, such as a hormone or neurotransmitter, to initiate a physiological response.
The drug works by blocking a specific receptor in the brain.
When the hormone attaches to its target receptor, it triggers a series of chemical changes inside the cell.
Genetic mutations can alter the shape of a receptor, preventing it from binding correctly with its intended ligand and leading to various metabolic disorders.
From Middle English receptour, from Old French receptour or Latin receptōrius, from recipiō (“receive”), from re- (“back”) + capiō (“I hold”).
Commonly followed by the preposition 'for' to indicate the specific substance it detects.
