Roles of FcgammaRIIB in nasal eosinophilia and IgE production in murine allergic rhinitis.

abstract：:Despite the increasing attention to the relationship between asthma and work exposures, occupational asthma remains underrecognized and its population burden underestimated. This may be due, in part, to the fact that traditional approaches to studying asthma in populations cannot adequately take into account the healt...
