Chronic Cholestatic Liver Disease Induced by Larval Ascariasis: Novel Insights Into Immune‐Mediated Pathogenesis and Hepatic Fibrosis in Mice

The FASEB Journal, Volume 40, Issue 10, 31 May 2026.
Liver alterations induced by single infection (SI) or reinfection (RE) with 250 or 2500 Ascaris suum eggs in mice. Histological analysis shows inflammatory cell infiltration (eosinophils, lymphocytes, macrophages, and neutrophils), fibrotic areas, and bile duct proliferation in infected animals compared with uninfected controls.
