Nucleotide metabolic rewiring enables NLRP3 inflammasome hyperactivation in obesity.

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
Obesity is a major disease risk factor due to obesity-associated hyperinflammation. We found that obesity induced Nod-like receptor pyrin domain-containing 3 (NLRP3) inflammasome hyperactivation and excessive interleukin (IL)-1β production in macrophages by disrupting SAM and HD domain-containing protein 1 (SAMHD1), a deoxynucleoside triphosphate (dNTP) hydrolase crucial for nucleotide balance. This caused aberrant accumulation of dNTPs, which can be transported into mitochondria, and initiated mitochondrial DNA (mtDNA) neosynthesis, which increased the presence of oxidized mtDNA and triggered NLRP3 hyperactivation. Deletion of SAMHD1 promoted NLRP3 hyperactivation in cells isolated from zebrafish, mice, and humans. SAMHD1-deficient mice showed elevated circulating IL-1β, insulin resistance, and metabolic dysfunction-associated steatohepatitis. Blocking dNTP mitochondrial transport prevented NLRP3 hyperactivation in macrophages from obese patients and SAMHD1-deficient mice. Our study revealed that obesity by inhibiting SAMHD1 rewired macrophage nucleotide metabolism, thereby triggering NLRP3 inflammasome hyperactivation to drive disease progression.
