中药复方提取物HNA-1对SIV慢性感染恒河猴胸腺输出及胸腺细胞发育的影响
Effects of HNA-1 Extracted from a Chinese Medicine Compound on the Thymic Output and Thymocyte Development in Rhesus Macaques with SIV Chronic Infection
摘要
Abstract
〔Abstract〕 Objective To investigate the effect of Chinese herbal extract HNA-1 on HIV-1 infection and AIDS. Methods Eight Chinese rhesus macaques had been infected by SIVmac239 for 16 to 21 months were enrolled into this study, the treatment group received HNA-1, control group received normal saline for consecutively 2 months, respectively. In predesigned time-points, peripheral blood were drawn for DNA extraction, and thereby thymic output was evaluated by T-cell receptor excision circle (TRECs) quantification. The thymocyte cells were seperated by enzyme digestion, the proportions of CD34 + cells and thymocytes in various development stages were analyzed by flow cytometry. Results Compared with control group, the thymic output function obviously was elevated in HNA-1 group (P<0.05). And the proportion of CD34+Lin-cells was significantly increased (P <0.05). More interestingly, the thymocytes in double positive (DP) stageⅡdecreased dramatically, while thymocytes in stage DP Ⅲ and stage DP Ⅳ increased. Conclusion Enhanced thymic output function may contribute to the effect of HNA-1 on AIDS treatment with underlying mechanisms involving increased thymic progenitor cells and promoted development of thymocytes from stage DPⅡ to stage DP Ⅲ.关键词
