產(chǎn)品詳情介紹
腫瘤壞死因子（tumor necrosis factor，TNF） ，主要由活化的單核/巨噬細(xì)胞產(chǎn)生，能殺傷和抑制腫瘤細(xì)胞，促進(jìn)中性粒細(xì)胞吞噬，抗感染，引起發(fā)熱，誘導(dǎo)肝細(xì)胞急性期蛋白合成，促進(jìn)髓樣白血病細(xì)胞向巨噬細(xì)胞分化，促進(jìn)細(xì)胞增殖和分化，是重要的炎癥因子，并參與某些自身免疫病的病理?yè)p傷[1-3]。根據(jù)其來(lái)源和結(jié)構(gòu)不同分為兩種類型，即TNF-α和TNF-β。TNF-α前體由233個(gè)氨基酸組成，其中包含由76個(gè)氨基酸殘基組成的信號(hào)肽，在TNF轉(zhuǎn)化酶TACE的作用下，切除信號(hào)肽，形成成熟的157個(gè)氨基酸殘基的TNF-α[4-5]。
