Figure 1 Antiatherogenic Effects of Adiponectin
Adiponectin has novel vascular actions to directly stimulate production of nitric oxide (NO) in endothelial cells using phosphatidylinositol (PI) 3-kinase-dependent pathways involving phosphorylation of endothelial nitric oxide synthase (eNOS) by adenosine-monophosphate-activated protein kinase (AMPK) (7) and reduces expression of adhesion molecules and decreases cytokine production from macrophage by inhibiting nuclear transcription factor kappa B (NF- B) signaling through cyclic adenosine-monophosphate-dependent pathways (23,24).
