Effect of different levels of alcohol consumption on natural killer and lymphokine activated killer cells

The effect of alcohol consumption on natural killer (NK) cell activity is controversial as both increased and decreased levels have been reported. It was the purpose of this study to determine the effects of feeding BDF1 mice different levels of alcohol on NK and lymphokine activated killer (LAK) cell activity. After four-six weeks of chronic alcohol feeding, mice were sacrificed, spleen cells obtained and assayed for NK and IL-2 boosted NK activity against YAC-1 cells in a traditional {sup 51}chromium release assay. Cells were also cultured in the presence of IL-2 for five days and tested for cytolytic activity using P815 cells as targets. Cells from each group were passed over a nylon wool column and the adherent (AD) and nonadherent (NAD) populations collected and tested as above. Increased NK, 24 hour IL-2 boosted NK and 5 day LAK activity were observed only in the spleen cells obtained from mice on 20% alcohol. Also, NAD populations had a 2-4 fold higher lytic unit values (LU{sub 20}) at all levels of alcohol consumption and in all assays, as compared with the unseparated spleen cells. Analysis of cell surface markers on these three populations of cells show that there were differences in MAC-2, Asialo GM-1, Thy 1.2, B220 and NK 1.1 that may correlate with the differences observed in the cytolytic assays. These data suggest that different levels of alcohol affect the cytolytic activity of NK and LAK cells and may result from alterations in the cell subset populations.
