Allergic immune responses help fight bacterial infections

Researchers from CeMM Research Center of Molecular Medicine of the Austrian Academy of Sciences, the Medical University of Vienna and Stanford University School of Medicine, have found that a module of the immune system, which is best known for causing allergic reactions, plays a key role in acquiring host defense against infections triggered by the bacterium Staphylococcus aureus. This “allergy module”, constituted by mast cells and Immunoglobulin E, can grant protection and increased resistance against secondary bacterial infections in the body. These findings indicate a beneficial function for allergic immune responses and are now published in the renowned journal Immunity.
