Regulatory B (Breg) cells are recognized as immunosuppressive cells. During the last years, several subsets of Breg cells, with different phenotypes and suppressive mechanisms, have been described in the literature. We aim to present a review based on an extensive literature research in PubMed, about the role of Breg cells on allergy.
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). 

Key words: Regulatory B cells, Allergy, Allergic disease, Allergen tolerance, B10, Br1, Asthma, Food allergy, Hymenoptera venom allergy, Pregnancy
