主要方法:

在1989年至2023年期间接受治疗的52名HIV-2感染者队列的回顾性分析.
基于血病毒载荷 (<200副本/毫升) 和CD4+T细胞计数 (>350细胞/毫米3) 的精英控制者的分类.
评估各种HIV-2疾病进展表型,包括非病毒性进展者和再控制者.

主要成果:

在40名被分析的参与者中,有13人被确定为精英控制者 (EC).
观察到不同的HIV-2轨迹,包括非病毒性进展者,失控者,经典进展者和独特的再控制器.
该队列主要来自西非 (80.8%),随访时间中位数为16年.

结论:

该研究在HIV-2精英控制者 (EC) 中确定了不同的临床和病毒学轨迹.

Retrovirus Life Cycles

Retrovirus Life Cycles

Retroviruses have a single-stranded RNA genome that undergoes a special form of replication. Once the retrovirus has entered the host cell, an enzyme called reverse transcriptase synthesizes double-stranded DNA from the retroviral RNA genome. This DNA copy of the genome is then integrated into the host’s genome inside the nucleus via an enzyme called integrase. Consequently, the retroviral genome is transcribed into RNA whenever the host’s genome is transcribed, allowing the...

Retroviruses

Retroviruses

Retroviruses and retrotransposons both insert copies of their genetic elements into the genome of the host cell. Thus, the viral genes are passed on when the host genome is replicated or translated. A typical retroviral DNA sequence contains 3-4 genes that encode the different proteins required for its structural assembly and function as a molecular parasite. This DNA is transcribed into a single mRNA, which is very similar in structure to conventional mRNAs, i.e., it is capped at the 5’...
