The single-cell immune landscape of HIV-associated aggressive B-cell lymphoma.

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
Background: Human immunodeficiency virus (HIV)-associated lymphomas (HAL), mainly aggressive B-cell lymphomas, pose a significant challenge in cancer research due to their multifaceted pathogenesis and aggressive clinical course. Despite the clinical importance, the genomic and immune characteristics of these lymphomas remain poorly elucidated. Methods: We employed single-cell RNA sequencing (scRNA-seq) on lymph node samples from aggressive B-cell lymphomas, mainly including 6 cases of diffuse large B-cell lymphoma (DLBCL) and 5 cases of Burkitt lymphoma (BL) from people living with HIV (PLWH), along with 3 DLBCL cases from individuals without HIV for comparison. Results: Malignant B cells in HAL consistently exhibited high proliferative and oxidative phosphorylation (OXPHOS)-type metabolic signatures. Moreover, these cells demonstrated loss expression of major histocompatibility complex class I (MHC-I), strategically reducing tumor immunogenicity. HAL harbors special populations of naive and atypical memory B cells that exhibited high metabolic and immune-activated transcriptional profiles. Additionally, HAL exhibited senescence-like dysfunction in T cells, characterized by the reductions in regulatory activity of Treg and cytotoxic activity of CD8 Conclusions: Our findings clearly indicate that HAL differs significantly from non-HAL, ranging from malignant B cells to the immune microenvironment. This study provides a comprehensive single-cell atlas of HIV-associated aggressive B-cell lymphomas, offering new insights into aggressiveness and immune evasion observed in HAL.
