cell receptors

; cell membrane receptors protein structures within cell membranes, activated by ligands (i.e. drugs, enzymes, biochemicals or hormones) to cause a cell membrane or intracellular effect; receptor numbers rise and fall in response to local needs and demand, e.g. receptor upregulation occurs when ligand-driven demand increases, and vice versa
