Research Topics
Our research explores how naturally occurring endogenous extracellular vesicles (EVs) can be leveraged to improve immune responses. Fusion of antigen with PS-binding proteins allows us to target antigens specifically to endogenous extracellular vesicles, creating a novel mode of antigen delivery. Such EV-targeted antigen (EVtAg) enables rapid and immune complex-independent delivery of antigen to follicular dendritic cells, accelerating activation of B cells and enhancing the quality of the adaptive immune response. Our findings uncover a new physiological pathway for B cell activation, which we are currently exploiting to create more effective vaccines.
