Liver-specific expression of ANGPTL8 promotes Alzheimer's disease progression through activating microglial pyroptosis.
Article in Journal of neuroinflammation, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
introductionLiver dysfunction contributes to Alzheimer's disease (AD) pathogenesis, and evidence suggests that the liver is involved in amyloid β (Aβ) clearance, and regulates Aβ deposition in the brain. However, the specific regulatory mechanism remains elusive.
objectivesAngiopoietin-like protein 8 (ANGPTL8), a high expression of liver-specific secreted proinflammatory factor, crosses the blood‒brain barrier from the bloodstream to abnormally activate microglia and promote AD progression.
methodsThe ANGPTL8
resultsANGPTL8 knockout improved cognitive function and reduced Aβ deposition by reducing microgliosis and microglial activation in 5xFAD mice. Mechanistically, ANGPTL8 crossed the blood‒brain barrier and interacted with the microglial membrane receptor PirB/LILRB2. This interaction subsequently activated the downstream NLRP3 inflammasome, leading to microglial pyroptosis and exacerbating the Aβ-induced release of inflammatory factors, thereby accelerating AD progression. Furthermore, the administration of metformin, an ANGPTL8 inhibitor, improved learning and memory deficits in 5 × FAD mice by negating microglial pyroptosis and neuroinflammation.
conclusionsANGPTL8 aggravates microglial pyroptosis via the PirB/NLRP3 pathway to accelerate the pathogenesis of AD. Targeting high expression of ANGPTL8 in the liver may hold potential for developing therapies for AD.
