WebNov 6, 2024 · Superantigens bind into the homodimer interface of CD28 and of B7-2, regions remote from where these two receptors interact, yet it is the binding of superantigen that triggers the CD28–B7-2 interaction (Figure 1A). To induce an inflammatory cytokine storm, superantigens thus subvert the costimulatory axis. WebMar 24, 2024 · A drug whose efficacy and affinity are sufficient for it to be able to bind to a receptor and affect cell function is an agonist. A drug with the affinity to bind to a receptor but without the efficacy to elicit a response is an antagonist. After binding to a receptor, an antagonist can block the effect of an agonist.
WebPlasma protein binding refers to the degree to which medications attach to proteins within the blood. A drug's efficiency may be affected by the degree to which it binds. The less bound a drug is, the more efficiently it can traverse or diffuse through cell membranes.Common blood proteins that drugs bind to are human serum albumin, … WebSep 13, 2024 · A cell receptor is a protein molecule to which substances like hormones, drugs, and antigens can bind.
