Research interests

The splenic marginal zone and gut mucosa can be viewed as interfaces between the immune system and the circulation or external environment, respectively. My group studies how B cells strategically positioned at these interfaces make antibodies against circulating or intraluminal antigens, including intestinal microbes. We are particularly interested in the mechanism whereby splenic stromal cells or splenic innate immune cells, including neutrophils, dendritic cells, macrophages and innate lymphoid cells, facilitate the activation of splenic marginal zone B cells. We are also analyzing how intestinal B cells generate antibodies to commensal bacteria and how these antibodies shape the composition of the gut microbiota. Finally, we study the alterations of B cells in patients with primary antibody deficiency, including selective IgA deficiency and common variable deficiency. Our research is relevant to infections, inflammation, autoimmunity, immunodeficiency and vaccine development.
