CD48

CD48(又稱BLAST-1或SLAMF2)為糖基磷脂酰肌醇(GPI)連接的免疫球蛋白超家族成員。CD48作為一個(gè)免疫共刺激分子和黏附分子,參與免疫性疾病的調(diào)控。人CD48基因定位于染色體1q21-23,其編碼產(chǎn)物為一種糖蛋白,分子量約為45kD。CD48表達(dá)于NK細(xì)胞、T細(xì)胞、單核細(xì)胞和嗜堿性粒細(xì)胞表面,參與這些細(xì)胞的粘附和活化途徑。CD48表達(dá)在炎性條件下會(huì)增加。研究發(fā)現(xiàn)當(dāng)IFN-α、IFN-β、IFN-γ等細(xì)胞因子暴露時(shí),可增加人外周血單核細(xì)胞CD48的表達(dá)。CD48的配體主要有CD2,CD244,F(xiàn)imH。CD48與多種配體結(jié)合,它的激活會(huì)引起脂質(zhì)筏中信號(hào)因子的重新排列、Lck激酶的活性以及酪氨酸磷酸化,從而發(fā)揮不同的免疫功能。大量研究表明,CD48在B和T淋巴細(xì)胞、NK細(xì)胞、肥大細(xì)胞和嗜酸性粒細(xì)胞中參與免疫調(diào)節(jié)機(jī)制,在自身免疫、炎癥、過(guò)敏、造血以及腫瘤中的發(fā)揮重要的作用。
