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)
