Conclusion
gp91phox plays a critical role in the differentiation of proinflammatory hepatic MΦs to a tissue-restorative phenotype, likely through programming for efferocytosis, and thereby lessens the severity of ALD. These findings enhance our understanding of the tissue environmental cues that regulate MΦ phenotypes. This knowledge could help in designing MΦ-targeting strategies to prevent and treat ALD.
