P . AERUGINOSA TYPE III AND TYPE VI SECRETION SYSTEMS MODULATE EARLY RESPONSE GENE EXPRESSION IN TYPE II PNEUMOCYTES IN VITRO

P . aeruginosa type III and type VI secretion systems modulate early response gene expression in type II pneumocytes in vitro

Abstract Background Lung airway epithelial cells are part of innate immunity and the frontline of defense against bacterial infections.During infection, airway epithelial cells secrete proinflammatory mediators that participate in the recruitment of immune cells.Virulence factors expressed by bacterial pathogens can alter epithelial cell gene expre
