AIM: To study the levels of membrane interleukin-2 receptor(mIL-2R ) and T cell subsets in peripheral bloodmononuclear cells (PBMC) from patients with hepatitis Cand their role in the pathogenesis of hepatitis C.METHODS: The levels of mlL-2R and T cells subsets in PBMCWere detected by biotin- streptstividin (BSA) technique beforeand after stimulation with PHA in 203 patients with hepatitis Cwith HCV-RNA( + ), anti-HCV( + ), anti-HCV(-).RESULTS: The total expressive levels of mlL-2R before andafter stimulation with PHA(0.03 ± 0.01, 0.03 ± 0.02, 0.04 ± 0.02, 0.36±0.03), and Tcell subsets in PBMC (0.62±0.06,0.37 ± 0.05, 0.35 ± 0.07) were all lower in patients withhepatitis C than those in normal controls (0.66 ± 0.07, 0.41± 0.06, 0.31 ± 0.05, P < 0.01 ). Among the patients, thelevels of mlL-2R were lower in silence than those in situationof PHA inducting (P< 0.01). However, the levels of mlL-2Rwere similar in acute hepatitis C to that in chronic hepatitis C(P>0.05). The levels of CD3+, CD4+, CD4 +/CD8+ Were lov erand CD8 + was higher in patients with acute and chronichepatitis C with anti-HCV( + ) than those in normal controls (0.62±0.06, 0.37±0.05, 0.35±0.07, 1.18±0.30, 0.61±0.07, 0.37±0.05, 1.39±0.33, 0.31±0.05, P<0.05-P<0.01).CONCLUSION: The cellular immunity is obviously changed inpatients with hepatitis C. The levels of mlL-2R end activationof T cells am closely associated with chronicity of hepatitis C.
AIM: To study the levels of membrane interleukin-2 receptor (mIL-2R) and T cell subsets in peripheral blood mononuclear cells (PBMC) from patients with hepatitis C and their role in the pathogenesis of hepatitis C. METHODS: The levels of mIL-2R and T cells subsets in PBMC were detected by biotin- streptatividin (BSA) technique before and after stimulation with PHA in 203 patients with hepatitis C with HCV-RNA(+), anti-HCV(+), anti-HCV(-). RESULTS: The total expressive levels of mIL-2R before and after stimulation with PHA(0.03+/-0.01, 0.03+/-0.02, 0.04+/-0.02, 0.36+/-0.03), and T cell subsets in PBMC (0.62+/-0.06, 0.37+/-0.05, 0.35+/-0.07) were all lower in patients with hepatitis C than those in normal controls (0.66+/-0.07, 0.41+/-0.06, 0.31+/-0.05, P<0.01). Among the patients, the levels of mIL-2R were lower in silence than those in situation of PHA inducting (P<0.01). However, the levels of mIL-2R were similar in acute hepatitis C to that in chronic hepatitis C (P>0.05). The levels of CD(3)(+), CD(4)(+), CD(4)(+)/CD(8)(+) were lower and CD(8)(+) was higher in patients with acute and chronic hepatitis C with anti-HCV(+) than those in normal controls (0.62+/-0.06, 0.37+/-0.05, 0.35+/-0.07, 1.18+/-0.30, 0.61+/-0.07, 0.37+/-0.05, 1.39+/-0.33, 0.31+/-0.05, P<0.05-P<0.01). CONCLUSION: The cellular immunity is obviously changed in patients with hepatitis C. The levels of mIL-2R and activation of T cells are closely associated with chronicity of hepatitis C.
