Effect of Ethanol-exposure on Innate Immune Response in Sepsis

J Leukoc Biol. 2023 Dec 8:qiad156. doi: 10.1093/jleuko/qiad156. Online ahead of print.ABSTRACTAlcohol use disorder, reported by one in eight critically ill patients, is a risk factor for death in sepsis patients. Sepsis, the leading cause of death kills over 270,000 patients in the United States alone and remains without targeted therapy. Immune response in sepsis transitions from an early hyper-inflammation to persistent inflammation and immunosuppression and multiple organ dysfunction during late sepsis. Innate immunity is the first line of defense against pathogen invasion. Ethanol exposure is known to impair innate and adaptive immune response and bacterial clearance in sepsis patients. Specifically, ethanol-exposure is known to modulate every aspect of innate immune response with and without sepsis. Multiple molecular mechanisms are implicated in causing dysregulated immune response in ethanol-exposure with sepsis, but targeted treatments have remained elusive. In this manuscript, we outline the effects of ethanol-exposure on various innate immune cell types in general and during sepsis.PMID:38066660 | DOI:10.1093/jleuko/qiad156
