The study aims to investigate how epithelial MLCK deficiency affects alcohol-associated liver disease (ALD) through the dendritic-Th17 cell pathway.
Utilized intestinal epithelial-specific Mylk knockout in a model of ALD.
Assessed gut permeability levels before and after Mylk knockout.
Evaluated changes in dendritic and Th17 cell interactions in the context of alcohol exposure.
MLCK deficiency significantly reduced gut permeability compared to controls (p<0.01).
Dendritic cell activation and Th17 cell expansion were decreased in Mylk knockout animals, suggesting a protective mechanism.
Significant reduction in markers of liver inflammation and damage related to alcohol exposure was observed.
Abstract
Highlights The MLCK-mediated leak pathway is upregulated in ALD. Intestinal epithelial-specific Mylk knockout protects against gut permeability and alcohol
