- Abstract
- Background. Influenza virus infection triggers acute cardiovascular events. Several studies have demonstrated that influenza A virus infection was associated with immune cell influx and increased production of inflammatory cytokines in the atherosclerotic plaque lesion, but the underlying mechanism for these findings is not clear. Methods. We examined the expression levels of matrix metalloproteinases (MMPs) by influenza A virus infection in human cells using quantitative real-time polymerase chain reaction, Western blot, and human MMP-13 enzyme-linked immunosorbent assay. In an animal study, protein expression in the plaque lesions of apolipoprotein E (ApoE)-deficient mice were analyzed by immunohistochemistry and Western blot. Results. We confirmed that MMP-13 was increased in influenza A virus-infected cells. In the aorta of infected ApoE-deficient mice, MMP-13 was increased at 3 days after infection. Immunohistochemical staining results suggested that collagen was degraded in the MMP-13 expression area and that macrophages were the main source of MMP-13 expression. Furthermore, the expression of MMP-13 was regulated by influenza A virus through activation of the p38 mitogen-activated protein kinase (MAPK) signaling pathway. Conclusions. In this study, we demonstrated that p38 MAPK-mediated MMP-13 expression by influenza A virus infection led to destabilization of vulnerable atherosclerotic plaques in the artery.
