An active HIV reservoir during ART is associated with maintenance of HIV-specific CD8+ T cell magnitude and short-lived differentiation status
Bibliographic record
Abstract
Before initiation of antiretroviral therapy (ART), HIV-specific CD8 + T cells are dysfunctional and short lived. To better understand the relationship between the HIV reservoir in CD4 + T cells and the magnitude and differentiation status of HIV-specific CD8 + T cells, we investigated these cells from acute and chronic HIV-infected individuals after 2 years of ART. Although both the HIV reservoir and the CD8 + T cell responses declined significantly after 2 years of ART, sustained HIV-specific CD8 + T cell responses correlated with a greater reduction of integrated HIV provirus. However, the magnitude of CD8 + T cells specific for HIV Gag, Pol, Nef, and Vif proteins positively associated with the active reservoir size during ART, measured as cell-associated RNA. Importantly, high HIV DNA levels strongly associate with maintenance of short-lived HIV-specific CD8 + T cells, regardless of ART initiation time. Our data suggest that the active reservoir maintains HIV-specific CD8 + T cell magnitude but prevents their differentiation into functional cells.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
