IL-12 Mediates T-bet-Expressing Myeloid Cell-Dependent Host Resistance against Toxoplasma gondii.
Article in ImmunoHorizons, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
To defend against intracellular pathogens such as Toxoplasma gondii, the host generates a robust type 1 immune response. Specifically, host defense against T. gondii is defined by an IL-12-dependent IFN-γ response that is critical for host resistance. Previously, we demonstrated that host resistance is mediated by T-bet-dependent ILC-derived IFN-γ by maintaining IRF8+ conventional type 1 dendritic cells during parasitic infection. Therefore, we hypothesized that innate lymphoid cells are indispensable for host survival. Surprisingly, we observed that T-bet-deficient mice succumb to infection quicker than do mice lacking lymphocytes, suggesting an unknown T-bet-dependent-mediated host defense pathway. Analysis of parasite-mediated inflammatory myeloid cells revealed a novel subpopulation of T-bet+ myeloid cells (TMCs). Our results reveal that TMCs have the largest intracellular parasite burden compared with other professional phagocytes, suggesting they are associated with active killing of T. gondii. Mechanistically, we established that IL-12 is necessary for the induction of inflammatory TMCs during infection and these cells are linked to a role in host survival.
