Using trypsin to render intact, isolated rat glomeruli permeable to antibody, and using an electron microscopic immunoperoxidase technique, we have localized a phagocytic immunologically-relevant cell bearing Ia determinants to the renal mesangium. Thus there are at least two functionally distinct cell types in the renal mesangium: one is a contractile smooth musclelike cell, and the other a phagocytic cell that bears immunologically-relevant surface determinants.
我们使用胰蛋白酶使完整分离的大鼠肾小球对抗体具有通透性,并采用电子显微镜免疫过氧化物酶技术,将一种带有Ia决定簇的与免疫相关的吞噬细胞定位到肾系膜。因此,肾系膜中至少存在两种功能不同的细胞类型:一种是具有收缩功能的平滑肌样细胞,另一种是带有与免疫相关表面决定簇的吞噬细胞。
