We previously demonstrated that both synthetic ( Exosurf ) and modified natural surfactant ( Survanta ) downregulated endotoxin-stimulated inflammatory c ytokine mRNA levels and protein products ( tumor necrosis factor-alpha [ TNF ] , interleukin-1-beta [ IL-1 ] , interleukin-6 [ IL-6 ] ) in human alveolar macrophages .
