摘要
Studies are summarized demonstrating that the inflammatory cytokines, interleukin IL-6 and IL-8, play a direct role in asbestos lung diseases and are produced by lung epithelial cells in direct response to the fibers. This response is controlled by changes in the cellular oxidative/state induced by iron present in the fiber through Fenton-type chemistry. As a result of this oxidative stress, the redox sensitive transcription factors, NF-kappa B and NF-IL-6, which help regulate cytokine gene expression, are activated.
