dc.description.abstract | High mobility group box 1 (HMGB1) protein is a danger-signaling molecule, known to activate an inflammatory response via TLR4 and RAGE. HMGB1 can be either actively secreted or passively released from damaged alveolar epithelial cells. Previous studies have shown that IL-1 beta, a critical mediator acute lung injury in humans that is activated by HMGB1, enhances alveolar epithelial repair, although the mechanisms are not fully understood. Herein, we tested the hypothesis that HMGB1 released by wounded alveolar epithelial cells would increase primary rat and human alveolar type II cell monolayer wound repair via an IL-1 beta-dependent activation of TGF-beta 1. HMGB1 induced in primary cultures of rat alveolar epithelial cells results in the release of IL-1 beta that caused the activation of TGF-beta 1 via a p38 MAPK-, RhoA- and alpha v beta 6 integrin-dependent mechanism. Furthermore, active TGF-beta 1 accelerated the wound closure of primary rat epithelial cell monolayers via a PI3 kinase alpha-dependent mechanism. In conclusion, this study demonstrates that HMGB1 released by wounded epithelial cell monolayers, accelerates wound closure in the distal lung epithelium via the IL-1 beta-mediated alpha v beta 6-dependent activation of TGF-beta 1, and thus could play an important role in the resolution of acute lung injury by promoting repair of the injured alveolar epithelium. | - |
