IL-27 signaling is not associated with CD44hi T cell apoptosis in septic mice
(A) Representative flow cytometric plots showing Caspase 3/7 (x axis) by SSC (y axis) on CD44hi memory CD4+ T cells in wild-type and Il27ra−/− mice on days 1 and 2 after sham surgery (“sham”) or CLP surgery (left). The frequency of apoptotic (Caspase 3/7+) CD44hi memory CD4+ T cells is summarized on the right.
(B) Representative flow cytometric plots showing Caspase 3/7 (x axis) by SSC (y axis) on CD44hi CD8+ T cells after sham or CLP surgery in wild-type and Il27ra−/− mice on days 1 and 2 after surgery (left). The frequency of apoptotic (Caspase 3/7+) CD44hi memory CD8+ T cells is summarized on the right. Data are representative of two experiments with n = 5–9 mice per group. Error bars represent the mean ± the standard deviation.
