Clinical Trial Summary

The objective of this study is to quantify the expression levels of the HIV-1 unspliced sense transcript and of total HIV-1 antisense transcripts in PBMCs of HIV-1-infected persons, either still untreated or virologically controlled on treatment, and to investigate their correlations with the HIV reservoir as assessed by the quantification of total and integrated HIV-1 DNA.

Clinical Trial Description

The research team will quantify the expression level of total HIV-1 antisense transcripts in PBMCs from two groups of HIV-1-infected persons: still untreated and virologically controllled on treatment. The research team will also study (i) the correlation between the expression level of total HIV-1 antisense transcripts and the levels of total and integrated HIV-1 DNA in PBMCs, (ii) the correlation between the expression level of the unspliced HIV-1 sense transcript and the levels of total and integrated HIV-1 DNA in PBMCs, (iii) the correlation between the expression levels of total HIV-1 antisense transcripts and the level of the unspliced HIV-1 sense transcript in PBMCs, (iv) whether the correlations are different in the two groups of HIV-1-infected persons : still untreated patients vs. patients with virological control on antiretroviral treatment. Quantification of viral transcripts will rely on quantitative RT-PCRs, yielding the quantity of viral RNAs, normalized on the expression of 2 housekeeping genes, and on a digital RT-PCR, yielding the absolute number of viral RNA copies. The quantification of total and integrated HIV-1 DNA will rely on a quantitative PCR yielding the number of HIV-1 DNA copies/million of PBMCs, according to the technique described in Tremeaux P et al, EBioMedicine 2019;41:455-64. The percentage of intact proviral DNA will be estimated according to the technique described in Bruner KM et al, Nature 2019; 566 :120-5 ;
