Super-resolution microscopy reveals ultra-low CD19 expression on myeloma cells that triggers elimination by CD19 CAR-T

CD19 CAR-T cells have achieved some success in treating myeloma patients despite the limited detection of the CD19 antigen. Here, the authors show using dSTORM that 10/14 myeloma samples studied express ultra-low levels of CD19, which are sufficient for engaging CAR-T cells in vitro.
