Progress in the association of high affinity IgE receptor with asthma / 国际儿科学杂志

Childhood asthma is one of type Ⅰ allergic diseases,and IgE is indispensable factor in development of asthma.IgE-antigen crosslinking of hish affinity IgE receptor(FcεRⅠ)leads to degranulation of mast cell,leukotriene synthesis and cytokine production.As a re8ult.such changes will bring about inflammation of airway and spasm of airway smooth muscle.Recent researches suggest that Src tyresine kinase play a vital role in their combination.This review discusses the regulation and signaling trannduction of FcεR Ⅰ and the relationship between FcεRⅠ and asthma.
