| Research Abstract |
This study demonstrated that Asian sand dust aggravated allergic airway inflammation, Japanese cedar pollinosis and atopic dermatitis along with the expression of pro-inflammatory mediators in experimental animal studies. Moreover, ASD caused the changes of inflammatory transcription factors and genetic susceptibility factors for exacerbation of allergic diseases. ASD aggravates allergic airway inflammation along with fibrous thickening of the subepithelial layer in the airway, whereas long -term sensitization attenuates these changes, suggesting that long-term sensitization may cause immune tolerance mediated by TGF-β. In epidemiology study, ASD event aggravated nasal, eye and pharygeal symptoms in young adults with and without allergic rhinitis. As for chronic obstructive pulmonary disease (COPD), the relation with ASD was not observed. Also ASD event caused an increase of clinic visits for allergic rhinitis, Japanese cedar pollinosis and asthma. These results suggest ASD is an environmental agent which aggravates allergic diseases including Japanese cedar pollinosis and asth ma.
