虽然在HIV/SIV感染中生发中心(GC)的形成、滤泡辅助T(TFH)细胞向淋巴器官内B细胞滤泡的募集以及淋巴组织结构的变化已经被证实,但其潜在的免疫病理学仍不清楚。在这里,我们总结已知的关于TFH细胞和GC B细胞在感染过程中的动力学以及与淋巴室结构变化相关的潜在的免疫病理学特征。本文还探讨了细胞动力学在病毒抑制抗逆转录病毒治疗前后次级淋巴器官增生性滤泡中病毒库的形成和维持中的意义。
Although the dynamics of germinal center (GC) formation, follicular helper T (TFH) cell recruitment to B cell follicles within lymphoid organs, and changes of lymphoid tissue architecture in HIV/SIV infection have been documented, the underlying immunopathology remains unclear. Here, we summarize what is known regarding the kinetics of TFH cells and GC B cells during the course of infection as well as the potential immunopathological features associated with structural changes in the lymphoid compartment. This review also explores the implications of cell dynamics in the formation and maintenance of viral reservoirs in hyperplastic follicles of secondary lymphoid organs before and after viral suppressive antiretroviral therapy.
