An FCER2 polymorphism is associated with increased oral leukotriene receptor antagonists and allergic rhinitis prescribing
CLINICAL AND EXPERIMENTAL ALLERGY(2021)
摘要
The Fc Fragment of IgE Receptor II (FCER2) is expressed in several cells, such as macrophages, eosinophils, B cells and platelets. Studies have suggested that FCER2 is involved in the regulation of IgE responses, growth and differentiation of T and B cells, cellular adherence and antigen presentation. The activation of the receptor results in down-regulation of IgE-mediated immune responses. Two studies found that individuals with asthma on inhaled corticosteroids (ICS) with the CC genotype of the rs28364072 polymorphism had a two-fold increased odds of asthma exacerbations and uncontrolled asthma than individuals with at least one copy of the T allele (CT/TT).
