Erythrocyte patch for enhanced B cell depletion therapy
A novel living cell therapy uses blood cells to enhance B cell depletion in blood cancers and autoimmune diseases, introducing a fundamentally new mechanism compared to existing drugs.
A novel living cellular therapeutic (CD20 EryPatch) that co-opts natural erythrocyte shape change to mechanically cross-link CD20 across large B cell surface areas while simultaneously flagging cells for macrophage clearance outperforms standard anti-CD20 monoclonal antibodies in preclinical disease models. Published in Science Advances, this represents a conceptually novel approach to B cell depletion therapy for hematologic malignancies and autoimmune diseases.
