JAK Inhibition Prevents Bone Loss and Reduces Inflammation in Experimental Periodontitis.
Article in Journal of periodontal research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
aimsThis study aimed to investigate the role of Janus kinase (JAK) signaling in the pathogenesis of periodontitis by evaluating the effects of pharmacological inhibition of JAK isoforms (JAK1 and JAK3) on periodontal inflammation and ligature-induced alveolar bone loss.
methodsExperimental periodontitis (EP) was induced by ligature placement around the mandibular first molars of rats. Concurrently, animals (n = 10 per group) received either a JAK1-3 inhibitor (JAK1-3i group), a JAK3 inhibitor (JAK3i group), or distilled water (EP group) via daily intragastric gavage for 7 days. A control group received only distilled water without ligature placement. Following euthanasia, the mandibles were evaluated using microcomputed tomography for bone loss, stereometric analysis for inflammatory infiltrate and blood vessels, Second Harmonic Generation Microscopy for collagen quantification, and immunohistochemistry to quantify CD45+ and CD3+ cell populations. Gingival tissues were assessed for inflammatory markers by RT-qPCR (Il-6, Tnf-α, and Rankl) and ELISA (TNF-α).
resultsLigature placement resulted in significant alveolar bone loss, increased osteoclast numbers, leukocyte infiltration, extracellular matrix degradation, and elevated expression of inflammatory markers. Treatment with both JAK1-3i and JAK3i effectively prevented bone loss and reduced osteoclast numbers. Histological and stereometric analyses showed reduced inflammatory infiltrate and improved tissue organization in both treated groups. JAK1-3i preserved collagen content more effectively and significantly reduced the number of CD45+ cells. Compared to the Experimental Periodontitis (EP) group, both inhibitors significantly downregulated the mRNA expression of Il-6, Tnf-α, and Rankl, and also reduced TNF-α protein levels in gingival tissues.
conclusionCollectively, the findings establish a mechanistic link between JAK signaling and inflammation-driven periodontal tissue destruction, providing new insights into the cellular and molecular events underlying the pathogenesis of experimental periodontitis.
