产品描述

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]

百日咳毒素(胰岛激活蛋白)是一种毒素,最初从百日咳杆菌中分离出来,用于研究细胞中的G蛋白偶联受体信号传导和动物实验性自身免疫性脑脊髓炎(EAE)。 百日咳毒素促进将NAD的ADP核苷酸转移给异源三聚体Gi / o蛋白的α亚基,导致受体与Gi / o蛋白解耦。 百日咳毒素也被用作佐剂,与特定抗原一起给动物接种以诱发多发性硬化症的动物模型EAE。 百日咳毒素最初被描述为胰岛激活蛋白,因为它引起了胰岛细胞对各种刺激产生持久增强的分泌反应,并刺激了Gi-连接α肾上腺能受体。
