Abstract
To study the correlation between the levels of IFN-γ and IL-4 and the expression of Fas and Bcl-2 in peripheral blood lymphocytes (PBL) in hemodialysis patients, the indirect immune fluorescein labeling method of flow cytometry and solid sandwich enzyme-linked immunosorbent assay were performed for detecting the expression of Fas and Bcl-2 in PBL and the levels of IFN-γ and IL-4 in the serum of 30 hemodialysis patients, respectively. It was found that the expression of Fas in PBL and the level of IL-4 in the serum of hemodialysis patients were significantly higher (P < 0.01), whereas Bcl-2 in PBL and IFN-γ in the serum were significantly lower (P < 0.01) than those of the normal controls. According to statistical analysis, the expression of Fas in PBL had a negative correlation with the level of IFN-γ, but a positive correlation with IL-4 in the serum of hemodialysis patients. Contrarily, the expression of Bcl-2 had a positive correlation with IFN-γ, but a negative correlation with IL-4 in the serum of hemodialysis patients. These results suggest that hemodialysis patients have a suppressed secretion of Th1-associated cytokine IFN-γ, but an increased secretion of Th2-associated cytokines IL-4, and these two aspects may play an important role in the abnormal apoptosis of PBL and its accompanying immune deficiency.
