为深入探讨鸡马立克氏病T细胞受体亚群的变化与疾病发生与发展的相互关系,本实验以马立克氏病强毒株人工感染1日龄SPF雏鸡,在不同的感染期,以流式细胞仪分析脾脏、胸腺、外周血淋巴细胞中TCR1+和TCR2+T细胞的动态变... 为深入探讨鸡马立克氏病T细胞受体亚群的变化与疾病发生与发展的相互关系,本实验以马立克氏病强毒株人工感染1日龄SPF雏鸡,在不同的感染期,以流式细胞仪分析脾脏、胸腺、外周血淋巴细胞中TCR1+和TCR2+T细胞的动态变化。结果表明,感染鸡脾脏中TCR1+T细胞异常增高,而TCR2+T细胞在脾脏和外周血中表现为暂短的升高,其后迅速下降。TCR1+T细胞与TCR2+T细胞的这种异常变化是vMDV感染雏鸡后T细胞表型变化的重要特征之一。 展开更多

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. 展开更多
