1 Here we show that TNF plays an important part in silica-induced pulmonary fibrosis in mice in that (1) a single instillation of silica leads to a marked increase in the level of lung TNF messenger RNA which lasts for greater than 70 days, while there are no obvious changes in the amounts of IL-1 alpha or TGF-beta mRNAs; and (2) silica-induced collagen deposition is almost completely prevented by anti-TNF antibody, but is significantly increased by continuous infusion of mouse recombinant TNF. Silicon Dioxide transforming growth factor, beta 1 Mus musculus
