尽管抗逆转录病毒治疗,但艾滋病毒在组织部位的持续存在是艾滋病毒治愈的主要障碍。对原生淋巴结组织环境中HIV感染细胞和免疫反应的详细研究对于深入了解影响组织避难所中HIV持续存在和清除的免疫机制至关重要。我们比较了14名在Fiebig I/II期开始治疗的患者、5名Fiebig III-V期治疗的患者和17名在Fiebig VI期及以后开始ART治疗的晚期患者的淋巴结活检中的HIV持久性和HIV特异性T细胞反应。使用多色免疫荧光染色和原位杂交,我们检测了14名Fiebig I/II患者中12人的HIV RNA和/或蛋白质,这些患者接受了1至55个月的抑制治疗,以及晚期治疗的持久性抗原患者。CXCR3+ T滤泡辅助细胞含有最多的gag mRNA转录物。值得注意的是,HIV特异性CD8+ T细胞反应与较低的HIV抗原负荷相关,这表明这些反应可能有助于治疗期间淋巴结中的HIV抑制。这些结果揭示了尽管在超急性感染中开始抗逆转录病毒治疗,但艾滋病毒仍然存在,并强调了在抑制性抗逆转录病毒治疗期间组织庇护所中病毒特异性反应对艾滋病毒抑制的贡献。尽管抗逆转录病毒治疗,艾滋病毒经常在组织避难所持续存在。在这项工作中,作者研究了在Fiebig I期及以后开始抗逆转录病毒治疗的个体的淋巴结活检中HIV的持久性和T细胞反应。
HIV persistence in tissue sites despite ART is a major barrier to HIV cure. Detailed studies of HIV-infected cells and immune responses in native lymph node tissue environment is critical for gaining insight into immune mechanisms impacting HIV persistence and clearance in tissue sanctuary sites. We compared HIV persistence and HIV-specific T cell responses in lymph node biopsies obtained from 14 individuals who initiated therapy in Fiebig stages I/II, 5 persons treated in Fiebig stages III-V and 17 late treated individuals who initiated ART in Fiebig VI and beyond. Using multicolor immunofluorescence staining and in situ hybridization, we detect HIV RNA and/or protein in 12 of 14 Fiebig I/II treated persons on suppressive therapy for 1 to 55 months, and in late treated persons with persistent antigens. CXCR3+ T follicular helper cells harbor the greatest amounts of gag mRNA transcripts. Notably, HIV-specific CD8+ T cells responses are associated with lower HIV antigen burden, suggesting that these responses may contribute to HIV suppression in lymph nodes during therapy. These results reveal HIV persistence despite the initiation of ART in hyperacute infection and highlight the contribution of virus-specific responses to HIV suppression in tissue sanctuaries during suppressive ART. Despite antiretroviral therapy, HIV often persists in tissue sanctuary sites. In this work, authors investigate HIV persistence and T cell responses in lymph node biopsies obtained from individuals who initiated antiretroviral therapy in Fiebig stage I and beyond.
