Background

Pertussis toxin (islet-activating protein) is a toxin, first isolated from B. pertussis, that is used to study G protein-coupled receptor signaling in cells and experimental autoimmune encephalomyelitis (EAE) in animals. Pertussis toxin catalyzes the transfer of the ADP-ribose moiety of NAD to the α subunits of heterotrimeric Gi/o proteins, resulting in the receptors being uncoupled from Gi/o proteins.[1],[2] Pertussis toxin is also used as an adjuvant, given with specific antigens, to immunize animals and induce EAE, an animal model of multiple sclerosis.[3],[4] Pertussis toxin was first described as an islet-activating protein because it caused a sustained potentiation of the secretory response of pancreatic islet cells to various stimuli that stimulate Gi-linked α-adrenergic receptors.[5],[6]
