1 · What the graph read from it

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.

2 · The registry

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

Inflammatory brain damage is an important factor contributing to mortality or lasting neurological sequelae in CNS infections, such as cryptococcal meningoencephalitis (CM), but little is known about natural immunoregulatory mechanisms in the infected brain. Here we report that regulatory T cells (Tregs) are a central immunoregulatory component in CM. Tregs are present within the CNS in both human CM patients and in the experimental murine CM. Treg-depletion exacerbates Th1-driven brain inflammation and neurological symptoms, accelerating mortality, despite enhanced fungal clearance in mouse CM. Aligned brain NanoString, scRNA-seq, and flow cytometry analyses revealed that Tregs reduce brain inflammation, especially T-cell recruitment activation and differentiation, shielding the brain from neurological damage. The major CNS-Treg recruitment appears to be chemokine receptor CCR8-mediated, supporting the importance of the CCR8/CCL1 axis in Treg recruitment into the brain. Tregs in CM are major producers of anti-inflammatory IL-10 and the growth factor Amphiregulin (Areg), which is implicated in neuronal repair. IL-10 deletion in murine CM phenocopies Treg depletion. Areg deletion showed no survival effect; however, IFN-γ production by effector T cells in the brain was reduced, supporting Aregs as a potential internal regulator of Treg immunosuppressive function. Finally, a Treg-enhancing immunotherapy using low dose IL-2-immune complex treatment substantially improves mouse survival and neurological outcomes. Together, we identified that Tregs are crucial for neuronal protection in CM, predominantly via IL-10 production, the CCR8-CCL1 axis is an important CNS-Treg recruitment mechanism and Treg enhancement is a potential therapeutic strategy to mitigate immunopathology during CM, and possibly other forms of meningitis.
