Immune tolerance, both to exogenous antigens and autoantigens, is essential for restraining undesired inflammatory responses that might result in severe damage to body tissues or cause chronic diseases. During the past few decades, different cell populations and molecules by them secreted have been associated with suppressing and regulatory mechanisms of immune responses. Although B cells typically acquire relevance as precursors of antibody-producing cells, they can also develop potent regulatory functions through the production of soluble molecules or by establishing direct cellular interactions mediated by different surface proteins implicated in signal transduction. While most studies of regulatory B cells define the role of these lymphocytes in autoimmune diseases, evidence of their importance and mechanisms of action in allergic diseases has accumulated in recent years. As a result, regulatory B cells appear to be relevant elements for the establishment or loss of allergen tolerance in different allergic diseases, although they still have been little explored.
