A chronic inflammatory disorder of the respiratory airways, asthma is characterized by
bronchial airway inflammation resulting in increased mucus production and airway hyper …

Concentrations of endotoxin in urban air pollution have not previously been extensively
characterized. We measured 24-hr levels of PM10 (particulate matter< 10 microm in …

Several studies show that ultrafine particles have a larger surface area than coarse particles,
thus causing a greater inflammatory response. In this study, we investigated chemical and …

Epidemiological and toxicological studies have suggested that the health effects associated
with exposure to particulate matter (PM) are related to the different physicochemical …

Essential cytoskeletal functions of macrophages are migration, phagocytosis of foreign
materials, and intracellular transport and digestion The influence of fine and ultrafine test …

Lung inflammation is a key response to increased levels of particulate air pollution (PM);
however, the cellular mechanisms leading to this response are poorly understood. To …

Infectious viruses and bacteria can trigger multiple sclerosis (MS) exacerbations. Seasonally
changing concentrations of ambient air pollutants are known to predispose to transmissible …

Polycyclic aromatic hydrocarbons (PAHs) appear to be significant contributors to the
genotoxicity and carcinogenicity of air pollution present in the urban environment for …

Interactions between alveolar macrophages (AMs) and epithelial cells may promote
inflammatory responses to air pollution particles. Normal rat AMs, the alveolar type II …

Recent epidemiological studies associate health effects and particulate matter in ambient
air. Exacerbation of the particle-induced inflammation can be a mechanism responsible for …
