Recognition of dsRNA byproducts released from apoptotic and necrotic cells is a recently proposed mechanism for the amplification of toxicity, suggesting a pivotal participation of TLR3 in viral infection, as well as in lung diseases where apoptosis plays a critical role, such as asthma and chronic obstructive pulmonary disease. In addition to metabolic control, insulin signaling was postulated to be protective by inhibiting apoptosis. Therefore, we explored the role of insulin signaling in protecting against TLR3-mediated apoptosis of human bronchial epithelial cells. Significant TLR3-mediated apoptosis was induced by polyinosinic-polycytidylic acid, a dsRNA analog, via caspase-8\u2013dependent mechanisms. However, insulin efficiently inhibited TLR3\/ polyinosinic-polycytidylic acid-induced human bronchial epithelial cell apoptosis via PI3K\/Akt and ERK pathways, at least in part, via upregulation of cellular FLIPs and through protein synthesis-independent mechanisms. These results indicate the significance of TLR3-mediated dsRNA-induced apoptosis in the pathogenesis of apoptosis-driven lung disease and provide evidence for a novel protective role of insulin.<\/jats:p>","DOI":"10.4049\/jimmunol.1004218","type":"journal-article","created":{"date-parts":[[2011,6,7]],"date-time":"2011-06-07T04:54:41Z","timestamp":1307422481000},"page":"510-519","source":"Crossref","is-referenced-by-count":23,"title":["Insulin-Dependent
