A specific type of glycosylation-sialylation-is more common on immunoglobulin E from individuals with a peanut allergys than from non-atopic people, suggesting that it has a role in regulating anaphylaxis.


Approximately one-third of the world'  s population suffers from allergies(1). Exposure to allergens crosslinks immunoglobulin E (IgE) antibodies that are bound to mast cells and basophils, triggering the release of inflammatory mediators, including histamine(2). Although IgE is absolutely required for allergies, it is not understood why total and allergen-specific IgE concentrations do not reproducibly correlate with allergic disease(3-5). It is well-established that glycosylation of IgG dictates its effector function and has disease-specific patterns. However, whether IgE glycans differ in disease states or affect biological activity is completely unknown(6). Here we perform an unbiased examination of glycosylation patterns of total IgE from individuals with a peanut allergy and from non-atopic individuals without allergies. Our analysis reveals an increase in sialic acid content on total IgE from individuals with a peanut allergy compared with non-atopic individuals. Removal of sialic acid from IgE attenuates effector-cell degranulation and anaphylaxis in several functional models of allergic disease. Therapeutic interventions-including removing sialic acid from cell-bound IgE with a neuraminidase enzyme targeted towards the IgE receptor Fc epsilon RI, and administering asialylated IgE-markedly reduce anaphylaxis. Together, these results establish IgE glycosylation, and specifically sialylation, as an important regulator of allergic disease.

Governments see coronavirus apps as key to releasing lockdowns. In exchange for people'  s health data, they must promise to work together to develop the highest standards of safety and efficacy.

People who carry the gene variant APOE4 are at higher-than-average risk of developing Alzheimer'  s disease. It emerges that this variant is linked to defects in the blood-brain barrier and subsequent cognitive decline.
