To establish a functional relevance of HMGB1-RAGE activation in microglia-mediated neuroinflammation, we used both pharmacological and genetic approaches involving HMGB1 translocation inhibitor ethyl pyruvate (EP), anti-HMGB1 siRNA, and NOX-inhibitor mitoapocynin. Interestingly, EP effectively reduced HMGB1 nucleocytoplasmic translocation and RAGE expression along with reactive oxygen species (ROS) generation and TNF- and IL-6 production but not NF-B activation. HMGB1 knockdown by siRNA also reduced both ROS and reactive nitrogen species (RNS) and IL-6 levels but not TNF-. NOX2 inhibitor mitoapocynin significantly reduced RNS levels. Collectively, our results demonstrate that organic dust activates HMGB1-RAGE signaling axis to induce a neuroinflammatory response in microglia and that attenuation of HMGB1-RAGE activation by EP and mitoapocynin treatments or genetic knockdown TBA-354 can dampen the neuroinflammation. and (rat, mice, and human volunteers) models (Charavaryamath models of microglial cells have been used to unravel mechanisms of neuroinflammation (Sarkar em et al. /em , 2017). Therefore, we tested a hypothesis that OD-exposure of microglial cells induces cell activation and inflammation through HMGB1-RAGE signaling. In the current manuscript, we show that OD-exposure of microglia induces microglial activation, production of reactive species and inflammatory cytokines. OD exposure leads to nucleocytoplasmic translocation of HMGB1, contributing to increased cell activation and inflammation. Using EP or anti-HMGB1 siRNA treatment, we demonstrate that OD-induced microglial activation and inflammation could be abrogated via HMGB1-RAGE signaling.
