Regulatory B Cells and Allergy: Uncovering the Link.

Abstract

Regulatory B (Breg) cells are recognized as immunosuppressive cells. During the last few years, several subsets of Breg cells with different phenotypes and suppressive mechanisms have been described in the literature. We review the role of Breg cells in allergy based on an extensive literature search in PubMed. We describe the types and mechanisms of action of B cells and their role in the pathogenesis of several allergic diseases (allergic asthma, allergic rhinitis, food allergy, contact hypersensitivity, and anaphylaxis).
