Abstract

: A comparative analysis of cellular and soluble markers of immune activation in HIV-infected women on combination antiretroviral therapy showed that the upper genital tract (UGT) compared to the lower female genital tract was characterized by higher frequencies of potential HIV target cells and increased inflammatory molecules. Despite the activated UGT milieu, HIV RNA could not be detected in paired samples of plasma, cervicovaginal or endometrial lavage. As antiretroviral concentrations were ≥3-fold higher in the endometrium than in the lower genital tract, high antiretroviral penetration and/or metabolism may limit viral replication in the UGT.

摘要

对接受联合抗逆转录病毒治疗的HIV感染女性的免疫激活细胞和可溶性标志物进行的比较分析表明,与女性下生殖道相比,上生殖道(UGT)的特征是潜在HIV靶细胞频率更高且炎症分子增加。尽管上生殖道环境处于激活状态,但在血浆、宫颈阴道或子宫内膜灌洗的配对样本中未检测到HIV RNA。由于子宫内膜中的抗逆转录病毒浓度比下生殖道高≥3倍,高抗逆转录病毒穿透率和/或代谢可能会限制上生殖道中的病毒复制。
