Lung Resident Memory B Cells Maintain Allergic Ige Responses In The Respiratory Tract, Alexander James Nelson

Dissertations

Immunoglobulin E (IgE) is the primary cause of allergic asthma. Allergen-specific IgE can be detected in the airway of allergic asthma patients even in the absence of circulating IgE, suggesting that IgE can be synthesized locally in the respiratory tract. However, the source of IgE-producing B cells, as well as how IgE responses arise and persist at mucosal sites are not fully understood. To address these questions, we modeled allergic asthma in mice by repeated intranasal administration of ragweed pollen and ovalbumin (OVA). We found that allergen exposure induced the production of local IgE in the airway and formation of …
