Role of gelatinase B and elastase in human polymorphonuclear neutrophil migration across basement membrane.

abstract：:Airway infections or irritant exposures during early postnatal periods may contribute to the onset of childhood asthma. The purpose of this study was to examine critical periods of postnatal airway development during which ozone (O(3)) exposure leads to heightened neural responses. Rats were exposed to O(3) (2 ppm) or...
