Figure 2. Improved nitric oxide (NO), but not EDHF-dependent vasodilation accounts for the vascular protective effects by anti-TNF-α, anti-LOX-1 and adiponectin.
Improvement of ACh-induced vasodilation in coronary arterioles in ApoE KO treated with anti-TNF-α antibody (A), anti-LOX-1 antibody (B) or adiponectin (C) was abolished by incubation with the nitric oxide synthase (NOS) inhibitor L-NAME. D. EDHF-induced vasodilation (ACh-induced dilation in the presence of L-NAME and indomethacin) was not significantly different among all groups. Data represent mean ± SEM. n=6–7 mice. Data were shown as mean ± SEM. *P<0.05 vs. WT, # P<0.05 vs. ApoE KO.
