A Potential Central Hub of Histamine in the Microbiota-Gut-Joint Axis in Rheumatoid Arthritis: Mechanisms and Translational Implications.
Review in International journal of molecular sciences, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Rheumatoid arthritis (RA) is a chronic autoimmune disease characterized by pain, persistent synovial inflammation, progressive joint destruction, and systemic immune dysregulation. Increasing evidence has revealed that the microbiota-gut-joint axis represents a crucial communication network linking intestinal dysbiosis to aberrant immune responses in RA. Among the diverse gut-derived metabolites implicated in this axis, we propose that histamine may act as a central signaling node linking microbial alterations to joint inflammation. Both host- and microbiota-derived histamine, synthesized via histidine decarboxylase (HDC), regulate immune and stromal cell activity within the joint microenvironment through histamine receptors H1R, H2R, and H4R. In addition, histamine interacts with other microbial metabolites-such as short-chain fatty acids (SCFAs) and tryptophan derivatives-forming an intricate metabolic-inflammatory network that amplifies fibroblast-like synoviocyte activation, osteoclastogenesis, and chronic inflammation. Despite accumulating evidence supporting the immunomodulatory role of histamine, the precise molecular mechanisms mediating its crosstalk with microbial and host immune pathways remain incompletely defined. This review provides a comprehensive overview of histamine-mediated regulation within the microbiota-gut-joint axis, emphasizing its interplay with other microbial metabolites and its contribution to RA pathogenesis. A deeper understanding of this histamine-centered microbiota-gut-joint axis will help elucidate its mechanistic role in immune dysregulation and may ultimately inform future strategies for restoring immune balance and preventing joint damage in RA.
