A terminal differentiation antigen, the senescent cell antigen, appears on the surface of senescent and damaged cells. Appearance of this antigen initiates immunologic binding of physiologic IgG autoantibodies and removal of the cells by macrophages. The senescent cell antigen appears to be derived from band 3, the major anion transport protein of erythrocytes. Both the senescent cell antigen and band 3 have been demonstrated in the membranes of all cells examined.
一种终末分化抗原,即衰老细胞抗原,出现在衰老和受损细胞的表面。这种抗原的出现引发生理性IgG自身抗体的免疫结合,并由巨噬细胞清除这些细胞。衰老细胞抗原似乎源自带3,即红细胞的主要阴离子转运蛋白。衰老细胞抗原和带3在所有检测细胞的膜中均已得到证实。
