The Role of IgA in the Manifestation and Prevention of Allergic Immune Responses.
Purpose of review: Immunoglobulin A (IgA) mediates immune exclusion of antigens in the gut. Notably, IgA plays also a role in the prevention of IgE-mediated allergies and induction of immune tolerance. The present review addresses the role of IgA in the manifestation of IgE-mediated allergies, including allergen-specific immunotherapy (AIT), the regulation of IgA production, and the mechanism of IgA in immune cell activation.
Recent findings: The majority of studies report an association of IgA with the induction of immune tolerance in IgE-mediated allergies. However, reports on the involvement of humoral and mucosal IgA, IgA subtypes, monomeric and polymeric IgA, and the mechanism of IgA-mediated immune cell activation are confounding. Effects by IgA are likely mediated by alteration of microbiota, IgE-blocking capacity, or activation of inhibitory signaling pathways. However, the precise mechanism of IgA-regulation, the contribution of serum and/or mucosal IgA, and IgA1/2 subtypes, on the manifestation of IgE-mediated allergies, and the underlying immune modulatory mechanism are still elusive.
期刊介绍：
The aim of Current Allergy and Asthma Reports is to systematically provide the views of highly selected experts on current advances in the fields of allergy and asthma and highlight the most important papers recently published. All reviews are intended to facilitate the understanding of new advances in science for better diagnosis, treatment, and prevention of allergy and asthma.
We accomplish this aim by appointing international experts in major subject areas across the discipline to review select topics emphasizing recent developments and highlighting important new papers and emerging concepts. We also provide commentaries from well-known figures in the field, and an Editorial Board of internationally diverse members suggests topics of special interest to their country/region and ensures that topics are current and include emerging research. Over a one- to two-year period, readers are updated on all the major advances in allergy and asthma.
