Alcohol delays O-glycosylation of CD43 on memory CD4+ T cells in sepsis.

<p>A) At 24h, there was no significant increase in CD43 expression in total CD4 cells in either water or alcohol-fed mice due to sepsis. By 72h, both water sepsis and alcohol sepsis groups increased CD43 expression over shams (H2O sham 81.4±7.0 vs H2O CLP 334.5±27.6, p = 0.004; EtOH sham 96.6±3.7 vs EtOH CLP 420.0±65.0, p = 0.04). B) At 24h, there was no significant increase in CD43 expression in naïve CD4 cells. By 72h, both water sepsis and alcohol sepsis groups increased CD43 expression over shams (H2O sham 1.6±0.4% vs H2O CLP 12.9±1.6%, p = 0.01; EtOH sham 1.7±0.1% vs EtOH CLP 20.2±4.8%, p = 0.01). C) At 24h, water septic mice showed significant upregulation of CD43 on memory CD4s (H2O sham 27.8±0.5% vs H2O CLP 55.4±4.2%, p = 0.02), while alcohol septic mice did not. By 72h, CD43 expression is increased in both water and alcohol sepsis groups compared to sham (H2O sham 31.9±0.5% vs H2O CLP 56.7±3.3%, p = 0.03; EtOH sham 29.1±1.4% vs EtOH CLP 50.6±4.5%, p = 0.02).
