CONCLUSION rh EPO treatment in hemodialysis patients exerts its improving effect on immune function via the increment of circulating red blood cell count, which directly influences. T lymphocyte function through combination of RBC LFA 3 with lymphocyte CD2 to enhance cytokine secretion. 结论:rhEPO不是直接影响患者免疫功能,而是增加RBC数量,间接通过红细胞表面LFA3与淋巴细胞表面CD2受体直接结合,增加细胞因子的分泌,影响T细胞功能。
