Interleukin 33 Promotes Liver Sinusoidal Endothelial Cell Dysfunction and Hepatic Fibrosis in Diabetic Mice.
Article in Diabetes & metabolism journal, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
backgruoundInterleukin 33 (IL33) drives liver fibrosis, and individuals with type 2 diabetes mellitus are more likely advanced to liver fibrosis. However, the role of IL33 in diabetic liver fibrosis remains unclear, prompting our investigation.
methodsWe developed a diabetes model in wild-type, IL33-/-, and suppression of tumorigenicity 2 (ST2-/-, IL33 receptor) mice. Furthermore, wild-type diabetic mice were injected with IL33 neutralizing antibody (αIL33). We also co-cultured human liver endothelial cells and human hepatic stellate cells to identify the role of IL33 in high palmitic acid and high glucose conditions.
resultsHepatic collagen deposition was increased in diabetic mice, which was alleviated by IL33 knockout, ST2 knockout, or administration of αIL33. Also, αIL33 treatment blunted liver sinusoidal endothelial cell (LSEC) dysfunction and inflammation during diabetic liver fibrosis progression. Recombinant IL33 (rIL33) treatment aggravated autophagy disruption in the presence of palm acid and high glucose in LSECs, which was blunted by autophagy agonist rapamycin administration and ERK/MAPK inhibitor PD98059 treatment. Hepatic stellate cell line LX-2 co-cultured with rIL33-pretreated LSECs displayed augmented activation, which was also attenuated by rapamycin or PD98059 pretreated.
conclusionIL33 drives LSEC dysfunction and promotes diabetic hepatic fibrosis, thus a potential therapeutic target for diabetic liver fibrosis.
