Chronic Ethanol Consumption Inhibits Hepatic Natural Killer Cell Activity and Accelerates Murine Cytomegalovirus‐Induced Hepatitis

Abstract: Taken together, these findings suggest that chronic ethanol consumption decreases hepatic NK activity, thereby accelerating MCMV-induced hepatitis and liver injury.

“…Second, activation of NK cells by poly I:C or IFN-γ inhibited liver fibrosis in pair-fed mice but not in ethanol-fed mice (Figures 2 and 4). Third, it has been well documented that alcohol consumption decreases NK cell activity and count in animal experiments 34,35 and in human alcoholics. 36 Down-regulation of hepatic NK cell number and activity after alcohol feeding was also confirmed in this study (Figure 3).…”

“…Показа-но, що при хронічній дії етанолу в організмі пригнічується природжений імунітет: пору-шується дозрівання Т-клітин, зменшується активність натуральних кілерів, розвивається запальний процес і знижується стійкість ор-ганізму до інфекційних захворювань [2,3].…”

“…In addition, decreased macrophage phagocytosis (12)(13)(14) and an increased Th2 response (11,15,16) were demonstrated in alcoholics. A decrease in the Ag-presenting abilities of dendritic cells (17), perforin/granzyme expression, IFN-g production by conventional NK cells (18,19), and Th1/Th17 responses (20)(21)(22) also were reported. All of these immune dysfunctions may be involved in the increased susceptibility of alcoholics to these infections.…”

“…Because such infections do not usually develop in healthy individuals, certain immune dysfunctions related to alcohol abuse are considered the underlying causes of the increased susceptibility of alcoholics to these infections. In fact, various host antibacterial immune functions are strongly influenced by chronic alcohol consumption (7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20)(21)(22). Decreased immune functions associated with chronic alcohol consumption include granulopoiesis (8), tissue recruitment of neutrophils (9), TLR responsiveness of macrophages (10), and production of IL-12 (11).…”
