CD4受體,全稱“表面抗原分化簇4受體”(Cluster of Differentiation 4 receptors),是輔助T細(xì)胞的表面標(biāo)記(surface markers)之一,也是輔助T細(xì)胞行使其功能的重要受體。當(dāng)抗原呈遞細(xì)胞(主要是巨噬細(xì)胞、棘狀細(xì)胞及B細(xì)胞本身)將外來病菌分解,把抗原與主要組織相容性復(fù)合體結(jié)合后,呈遞給輔助T細(xì)胞(即與輔助T細(xì)胞表面的CD4受體結(jié)合),輔助T細(xì)胞再接著刺激B細(xì)胞產(chǎn)生抗體,此即體液性免疫反應(yīng)的基本過程。
