CD47

CD47,白細(xì)胞表面抗原 CD47,也被稱為整合素相關(guān)蛋白(IAP)或MER6蛋白。CD47屬于免疫球蛋白超家族成員,廣泛表達(dá)于多種細(xì)胞表面,由人類CD47基因編碼。CD47的作用機(jī)制主要涉及與信號(hào)調(diào)節(jié)蛋白α的相互作用,通過磷酸化激活SIRPα,招募和激活SHP磷酸酶,進(jìn)而介導(dǎo)肌球蛋白2a去磷酸化,導(dǎo)致巨噬細(xì)胞對(duì)攜帶CD47的細(xì)胞的吞噬作用減弱,從而負(fù)調(diào)節(jié)吞噬作用。CD47在維持良性細(xì)胞的免疫耐受中起著關(guān)鍵作用,確保自體細(xì)胞不會(huì)被不適當(dāng)?shù)赝淌?。然而,許多不同類型的癌癥細(xì)胞利用CD47的高表達(dá)來介導(dǎo)免疫逃逸,逃避被巨噬細(xì)胞吞噬的命運(yùn)。CD47的阻斷劑正在被開發(fā)用于促進(jìn)巨噬細(xì)胞吞噬腫瘤細(xì)胞,作為癌癥治療的潛在策略。
