 AB    Alcoholic patients often have impaired immune function, yet little is
       known about the precise mechanism(s) of this impairment. We have
       previously shown that ethanol consumption by mice alters
       copolymer-specific humoral and cellular immune responses. In this study,
       we asked whether alcohol consumption by mice would phenotypically alter
       lymphocyte populations. Female C57BL/6 mice were fed a nutritionally
       complete liquid diet containing 35% ethanol-derived calories for up to 8
       days. As controls, mice either were fed a liquid control diet that
       isocalorically substitutes sucrose for ethanol or remained on a standard
       solid diet and water ad libitum. Although mice fed ethanol-containing
       liquid or pair-fed control liquid diets have decreased numbers of spleen
       cells compared with solid diet controls, only the ethanol-containing
       diet allowed normally nonresponder C57BL/6 spleen cells to make antibody
       responses to the poly(Glu50Tyr50) synthetic copolymer antigen. Flow
       cytometric analysis of splenic lymphocyte populations of mice on the
       ethanol-containing diet shows an increase in the relative proportion of
       T-lymphocytes as compared with mice on either solid or liquid control
       diets. No such change is seen for either B-cell or natural killer cell
       populations in these same mice. Both liquid control and liquid ethanol
       diets caused a slight decrease in the CD4:CD8 ratios of splenic
       T-lymphocytes. We see the relative percentage of T-cells bearing the
       alpha beta T-cell receptor (TcR) increases in the spleens of liquid
       ethanol diet mice; a smaller increase TcR alpha beta usage is seen in
       the spleens of liquid control mice, compared with solid diet
       mice.(ABSTRACT TRUNCATED AT 250 WORDS)
