Resumen en inglés | The present study was designed to examine the effects of atorvastatin on vascular inflammatory responses in human coronary artery endothelial cells(HCAECs), when challenged by lipopolysaccharide (LPS), a Toll-like receptor-4 (TLR4) ligand. HCAECs were pretreated with atorvastatin and induced by LPS. The expression of TLR4, interleukin -6(IL-6), monocyte chemoattractant protein 1(MCP-1), vascular cell adhesion molecule-1 (VCAM-1), intercellular adhesion molecular-1(ICAM-1), nuclear factor-κB (NF-κB) and p38 mitogen activated protein kinase(p38 MAPK) were evaluated using Real-time polymerase chain reaction, cytokine ELISA assay and Western blotting. The results showed that pretreatment with atorvastatin down-regulated the expression of TLR4 in LPS-activated HCAECs. Atorvastatin also attenuated the LPS-induced expression of interleukin IL-6 and MCP-1, at both the transcription and translation level in HCAECs. LPS-induced endothelial cell adhesion molecules, ICAM-1 and VCAM-1 expression were also reduced by pretreatment with atorvastatin. Furthermore, atorvastatin efficiently suppressed LPS-induced phosphorylation of NF-κB and p38 MAPK in HCAECs. These findings show that atorvastatin suppresses endothelial cell inflammation, suggesting that atorvastatin may be suitable for development as a therapeutic agent for inflammatory cardiovascular disease |
