Effects of loss of TLR4 on vasodilatation and vascular senescence. A Effect of aging and TLR4 knockout on the endothelium-dependent vascular relaxation response to acetylcholine. B Effect of aging and TLR4 knockout on the endothelium-independent vascular relaxation response to sodium nitroprusside. C Representative Western blots of p16 and p53 in aortas of mice in different groups. F Statistical results of p16 and p53 in aortas. n = 6 for each group. *P < 0.05, **P < 0.01, ***P < 0.001, ****P < 0.0001 vs. Young Group. #P < 0.05, ###P < 0.001 vs. Aged Group
