IL-1β signaling modulates T follicular helper and regulatory cells in human lymphoid tissues.

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
Dysregulation of T follicular helper (Tfh) and T follicular regulatory (Tfr) cell homeostasis in germinal centers (GCs) can lead to antibody-mediated autoimmunity. While IL-1β modulates the GC response via IL-1R1 and IL-1R2 receptors on follicular T cells in animal models, its role in humans remains unclear. We analyzed Tfh and Tfr phenotypes in human secondary lymphoid organs (tonsils, spleen, and mesenteric lymph nodes) using flow cytometry, single-cell transcriptomics, and in vitro culture, comparing findings with samples from autoimmune patients. We observed organ-specific Tfh/Tfr phenotypes according to activation status and IL-1 receptor expression. An excess of IL-1R1 over IL-1R2 expression promoted a unique activated Tfr subset with Treg and GC-Tfh features. IL-1β signaling via IL-1R1 enhanced follicular T cell activation and Tfh-to-Tfr differentiation, while IL-1β inhibition upregulated IL-1R1, indicating a tightly regulated process. In autoimmune patients, high IL-1β and circulating Tfr levels correlated with increased autoantibody production, linking inflammation, IL-1β signaling, and Tfr/Tfh balance. Our findings highlight the critical role of IL-1β in follicular T cell activation and suggest that targeting IL-1β signaling in Tfh and Tfr cells could be a promising strategy for treating antibody-mediated autoimmune diseases.
