GDF3 promotes adipose tissue macrophage-mediated inflammation via altered chromatin accessibility during aging.
Article in Nature aging, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
Aging is characterized by amplified inflammation, including proinflammatory macrophages and increased susceptibility to endotoxemia. Here we uncover a mechanism by which macrophages maintain their inflammatory phenotype through autocrine GDF3-SMAD2/3 signaling, which ultimately exacerbates endotoxemia. We show that inflammatory adipose tissue macrophages display an age-dependent increase in GDF3, a TGFβ-family cytokine. Lifelong systemic or myeloid-specific Gdf3 deletion leads to reduced endotoxic inflammation. Using pharmacological interventions to modulate the GDF3-SMAD2/3 axis, we demonstrate its role in regulating the inflammatory adipose tissue macrophage phenotype and endotoxemia lethality in old mice. Mechanistically, single-cell RNA sequencing and assay for transposase-accessible chromatin with sequencing analyses suggest that GDF3 induces a shift toward an inflammatory state by limiting methylation-dependent chromatin compaction. Leveraging human adipose tissue samples and 11,084 participants from the atherosclerosis risk in communities study, we validate the relevance of GDF3 to aging in humans. These findings position the GDF3-SMAD2/3 axis as a critical driver of age-associated chromatin remodeling and a promising therapeutic target for mitigating macrophage-related inflammation in aging.
