About B Cells – A New Class of Cellular Medicines

Imagine what could “Be?” In nature, a single B cell engrafts in the bone marrow and can produce thousands of proteins per second at constant levels over decades. B cells are nature’s exquisite medicine factories, manufacturing proteins to fight disease and maintain health. Unleashing the power of B cells is driving a new class of cellular medicines – Engineered B Cell Medicines (BeCM). BeCMs have the potential to be durable, allogeneic, redosable and administered without toxic conditioning. The promise of BeCMs could transform therapeutic biologics with broad application — across protein classes, patient populations and therapeutic areas.
