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

Adenosine signaling plays protective roles in gingival mitochondrial health and inflammation control, with the ectoenzyme CD73 implicated in periodontitis. Here, we investigated the effects of selective adenosine A2a receptor (A2aR) stimulation using the agonist CGS21680 in a mouse model of ligature-induced periodontitis (LIP) and in gingival fibroblast mitochondrial function. Mature C57Bl/6 mice underwent LIP and received daily intraperitoneal injections of CGS21680 (0.1 mg/Kg) or saline. After 8 days, gingival tissues and maxillae were analyzed for alveolar bone loss and Il-1β levels. In parallel, murine gingival fibroblasts (mGFs) were treated with Tnf-α (5 ng/mL) ± CGS21680 (10 µM) to assess mitochondrial function, morphology, and quality control. A2aR activation significantly reduced alveolar bone loss and Il-1β expression in vivo. In vitro, CGS21680 suppressed Tnf-α-induced Cxcl10 and Cxcl12 expressions and enhanced Vegf production. Mitochondrial analysis revealed increased mitochondrial complex levels, membrane potential, and mass, alongside reduced reactive oxygen species (ROS), proton leak, and mitochondrial stress. Ultrastructural studies showed elongated, healthier mitochondria and increased pro-fusion markers, indicating enhanced mitochondrial quality control. Overall, A2aR stimulation attenuates periodontal inflammation and confers mitoprotective effects on gingival fibroblasts, supporting its potential as a therapeutic strategy to both mitigate periodontitis progression and preserve tissue bioenergetics supporting cellular resilience.
