Role of endotoxin in tumor necrosis factor alpha expression from alveolar macrophages treated with urban air particles.

abstract：:Diesel exhaust particles (DEP) are associated with respiratory disease and exposure to diesel exhaust induces an inflammatory response associated with marked leukocytic infiltration in the lung. This study examined whether neutrophils are activated by the active component of DEP (methanol extract of DEP [me-DEP]). The...
