Cigarette smoking is the major factor responsible for chronic obstructive lung disease, but it occurs in only a minority of smokers. Smoking is associated with increased susceptibility to pulmonary infections and with a neutrophil- and macrophage-rich inflammation of the small airways. We compared concentrations of tumor necrosis factor (TNF), interleukin(More)
The pyrogenic cytokines tumor necrosis factor-alpha (TNF-alpha) and interleukin-6 (IL-6) appear in the circulation during infections and injuries, but TNF-alpha and IL-6 are regulated differently in macrophages. We compared the effects of elevated temperatures within the usual febrile range on the expression of TNF-alpha and IL-6 in vitro in(More)
Cigarette smoking is the major factor responsible for chronic obstructive pulmonary disease (COPD). COPD occurs in a minority of smokers, but the host factors that modify risk of disease have not been clearly elucidated. There is significant clinical and histopathologic overlap between COPD and asthma, including the accumulation and activation of airway(More)
This chapter summarizes data from epidemiologic and animal model studies which demonstrate that an inherited predisposition influences the incidence of lung cancer. The authors review the cell biologic events that contribute to neoplastic transformation and the biologic processes that influence tumor progression. They describe how host mechanisms may limit(More)
ABSTRACT: Although considerable evidence suggests that bronchopulmonary dysplasia (BPD) is the result of prolonged inflammation and impaired healing of the immature lung, the mediators that regulate inflammation in neonatal lung injury have not been completely elucidated. We examined whether the cytokines IL-6 and tumor necrosis factor-α (TNF) interact to(More)
