Interferon-γ production by neutrophils during bacterial pneumonia in mice.

abstract：:Cigarette smoking causes the development of chronic bronchitis and chronic obstructive pulmonary disease. We hypothesized that exposure to cigarette smoke might initiate release of inflammatory mediators by bronchial epithelial cells. To evaluate this, the effect of cigarette smoke extract (CSE) on IL-8 release from c...
