Parietal pleural plaques and visceral pleural fibrosis are well-recognized stigmata of occupational asbestos exposure. However, their pathogenesis is poorly understood. Conceivably, phagocytosis of asbestos fibers by pleural mesothelial cells may sti

Silicosis is characterized by mononuclear cell aggregation with mineral particles and fibrosis. Lymphocytes are abundant in these lesions. We exposed inbred strains of mice to a respirable aerosol of cristobalite silica (70 mg/m3, 5 h/d, 12 d) or sha

The cytokines interleukin-1beta (IL-1beta) and tumor necrosis factor-alpha (TNFalpha), derived from macrophages and other cells, may promote mononuclear cell inflammation and fibrosis in pulmonary silicosis. C3H/HeN mice were exposed to control air o

Experimental silicosis allows study of the mechanisms of lung injury, inflammation, and fibrosis. Inbred mice are an attractive species in which to study these mechanisms because of recent progress in murine immunology, molecular biology, and genetic

Transforming growth factor-alpha (TGF-alpha) a cytokine having potent mitogenic activity for epithelial and mesenchymal cells, may play a role in the lung remodeling of silicosis. Lung macrophages are among the major cells producing TGF-alpha in a lu

Knowledge about the health effects of exposure to formaldehyde associated with automotive emissions is of pivotal importance in the risk assessment of this agent. Mobile sources emit many combustion-derived pollutants, including formaldehyde, in asso

Alpha-cristobalite causes pulmonary interstitial disease in humans and experimental animals. Aerosol exposure of rats to cristobalite for 8 days results in early and sustained alveolar type II cell hyperplasia in areas of inflammation characterized b

Cristobalite is a crystalline silicon dioxide that elicits pulmonary inflammation and fibrosis in humans and experimental animals. Exposure of rats to aerosols of respirable cristobalite for 8 days led to a rapid influx of neutrophils and macrophages
