A) Representative flow plot for frequency of CD69+CD43+ of CD4+ CD44hi at 24h. B) Representative flow plot for frequency of CD69+CD43+ of CD4+ CD44hi at 72h. C) By 24h, there was significant increase in CD69+ CD43+ population in naïve CD4s in water sepsis (H2O sham 0.4±0.04% vs H2O CLP 1.6±0.4%, p = 0.03). This population was not increased in alcohol sepsis. By 72h, both water septic and alcohol septic groups showed significant increase in the CD69+ CD43+ population (H2O sham 0.3±0.08% vs H2O CLP2.5±0.4%, p = 0.02; EtOH sham 0.3±0.05% vs EtOH CLP 3.5±0.5%, p = 0.01). D) In memory CD4s, at 24h there was a significant increase in CD69+ CD43+ population in water sepsis (H2O sham 6.2±0.7% vs H2O CLP 23.7±4.2%, p = 0.02) but not alcohol sepsis. By 72h, both water and alcohol septic groups show significant increase in this population above sham controls (H2O sham 11.4±-.2% vs H2O CLP 30.8±1.8%, p = 0.04; EtOH sham 10.3±0.9% vs EtOH CLP 32.9±2.6%, p = 0.005). n = 4-8/group.
