CD28 Deficiency Ameliorates Blast Exposure-Induced Lung Inflammation, Oxidative Stress, Apoptosis, and T Cell Accumulation in the Lungs via the PI3K/Akt/FoxO1 Signaling Pathway
CD28 deficiency ameliorates blast exposure-induced lung tissue apoptosis. (a, b) Representative images and semiquantitative analysis of lung tissue apoptosis (TUNEL staining, ). (c–g) Representative western blot images and quantitative analysis of Caspase-3, Caspase-8, Bcl-2, Bax, and β-actin in each group. Fold changes of WT (green bar) and CD28-/- (red bar) expressions are shown. All experiments were repeated at least three times. Results are expressed as the ( per group). versus the control group; versus the WT group (two-way ANOVA; Bonferroni post hoc test). WT: C57BL/6 wild-type mice; CD28-/-: CD28 knockout mice.
