Hypoxia drives progression of multiple sclerosis by enhancing the inflammasome activation in macrophages with Porphyromonas gingivalis infection.

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
Porphyromonas gingivalis (Pg), a gram-negative anaerobic bacterium, is a leading pathogen causing periodontitis. It secretes several virulence factors, including gingipains, lipopolysaccharides (LPS), and outer membrane vesicles (OMVs), which can trigger the release of inflammatory cytokines such as interleukin (IL)-1β, tumor necrosis factor alpha (TNFα), and IL-6 through inflammasome activation and Toll-like receptor (TLR) signaling. We demonstrated that Pg infection under hypoxic conditions enhances NLRP3 inflammasome activation in macrophages. Additionally, we observed that toll-interleukin-1 receptor domain-containing adaptor-inducing interferon-β (TRIF)-mediated hypoxia-inducible factor 1 alpha (HIF-1α) regulation exacerbates inflammasome activation under hypoxia. Notably, HIF-1α deficiency in myeloid cells reversed neurological symptoms and reduced IL-1β and IL-17 production in a mouse model of multiple sclerosis with Pg infection. Our findings indicated that hypoxia modulates inflammasome activation in response to periodontitis-related bacterial infections, contributing to the progression of autoimmune diseases.
