  • Publication number: 20220081481
    Abstract: Sustained hepatic and systemic inflammation, in particular originating from monocyte/macrophages, is a driving force for chronic liver disease progression to cirrhosis and underlies the development of multiorgan failure. Therefore, reprogramming mono-cyte/macrophage phenotype has emerged as an interesting strategy to limit inflammation during chronic liver injury. The inventors report here that a non-canonical form of autophagy, LC3-associated phagocytosis (LAP), is endogenously enhanced in blood and liver monocytes from cirrhotic patients and is negatively correlated to the levels of inflammatory markers in these patients. Pharmacological inhibition of LAP components or genetic disruption of LAP (Rubicon-deficient mice in myeloid cells), exacerbates the inflammatory signature in isolated human cirrhotic monocytes and the hepatic inflammatory profile in mice with chronic liver injury, resulting in enhanced liver fibrosis.

  • Publication number: 20210403573
    Abstract: Persistent inflammation is a driving force of fibrosis progression. Mucosal-Associated Invariant T (MAIT) cells are non-conventional T cells that display altered functions during chronic inflammatory diseases. Here, the inventors report a loss of circulating MAIT cells in cirrhotic patients and their hepatic accumulation in an activated phenotype within the fibrotic septa. Using two models of chronic liver injury, the inventors demonstrate that mice enriched in MAIT cells (V?19TCRTg) show exacerbated liver fibrosis and higher number of hepatic fibrogenic cells than wild type counterparts, whereas MAIT cell-deficient mice (MR1?/?mice) are resistant. The results highlight the profibrogenic functions of MAIT cells and suggest that 1 targeting MAIT cells may constitute an attractive antifibrogenic strategy during chronic liver injury.
