Early treatment and PD1 inhibition enhance HIV-specific functionality of follicular CD8+ T cells.
Article in JCI insight, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
People living with HIV treated during acute infection are the group for whom achieving functional cure appears most viable. Follicular CD8+ T cells could contribute to HIV reservoir clearance by accessing B cell follicles through CXCR5 expression. This study examines peripheral follicular CD8+ T cells using flow cytometry, transcriptome analyses, and functional assays in people treated during acute (n = 37) and chronic (n = 18) infection, as well as in individuals naturally controlling HIV (n = 20) and living without HIV (n = 10). Our results reveal that early, as opposed to late, treatment initiation preserves antiviral effector functions of follicular CD8+ T cells, which are further enhanced by PD1 inhibition. We also identify a correlation between follicular CD8+ T cells and intact proviral HIV DNA levels in acute, but not chronic, infection. Longitudinal transcriptomic analysis of peripheral effector cells after 48 weeks of suppressive therapy indicated traits of recent antigen exposure, suggesting potential recirculation into lymphoid tissue. These findings underscore the pivotal role of follicular CD8+ T cells in anti-HIV responses and support investigating targeted cure strategies, such as anti-PD1 therapy, especially in individuals initiating treatment during acute infection.
