Summary of the 2019 Alcohol and Immunology Research Interest Group (AIRIG) meeting: Alcohol-mediated mechanisms of multiple organ injury.

Abstract On November 15, 2019, the 24th annual Alcohol and Immunology Research Interest Group (AIRIG) meeting was held as a satellite conference during the annual Society for Leukocyte Biology meeting in Boston, MA. The 2019 meeting focused on alcohol, immunity and organ damage and included two plenary sessions. The first session highlighted new research exploring the mechanisms of alcohol-induced inflammation and liver disease including effects on lipidomics and lipophagy, regulatory T cells, epigenetics, epithelial cells and age-related changes in the gut. The second session covered alcohol-induced injury of other organs, encompassing diverse areas of research ranging from neurodegeneration, to lung barrier function, to colon carcinogenesis, to effects on viral infection. The discussions also highlighted current laboratory and clinical research used to identify biomarkers of alcohol use and disease.
