Pectin alleviates alcohol-associated liver disease partly through cell-type-specific aryl hydrocarbon receptor signaling in female mice.

Pectin reduces alcohol-associated liver disease in female mice through activation of AhR across multiple cell types, despite cell-specific AhR deficiencies.

• Why it matters: Understanding the cellular mechanisms of AhR in ALD is crucial because it may reveal targeted strategies for treatment, as AhR is expressed in various organs and cell types.
• What they did: Researchers generated conditional AhR knockout mice in intestinal epithelial cells, hepatocytes, dendritic cells, and Rorγt-positive cells, then induced ALD with the Lieber-DeCarli model and supplemented with pectin.
• The result: Pectin provided strong protection against ALD in all models, indicating that activation of AhR across multiple cell types, rather than a single cell type, mediates its protective effects.
