Dexamethasone-conjugated polyethylenimine/MIF siRNA complex regulation of particulate matter-induced airway inflammation.
Abstract Inhalation of airborne particulate matter (PM), such as silicon dioxide (SiO2) and titanium dioxide (TiO2), induces acute lung inflammation. siRNA therapy has been proposed as a method to repair acute lung inflammation. To determine whether DEXA-PEI/MIF siRNA contributes to SiO2-induced acute lung inflammation repair, we administered Dexa-PEI/MIF siRNA in SiO2-treated Beas-2b cells and instilled DEXA-PEI-MIF siRNA intratracheally in mice with SiO2-induced acute lung inflammation. Using genetic (MIF mRNA RT-PCR), histological (H&E and PAS) and immunohistochemical (MIF and Muc5ac) analyses, we estimated...
