Researchers from the University of California, Los Angeles, have unveiled a new platform that combines a flexible material called graphene oxide with antibodies to closely mimic the natural interactions between immune cells. The investigators found that this platform shows a high capacity for stimulating T cells to reproduce, while preserving their versatility and potency. The advance could make CAR-T cell therapy more effective and accessible. In this type of therapy, patients' own immune cells are collected, genetically engineered so that they specifically target cancer cells, and then returned to the body. The new technology enhanced the efficiency of engineering immune cells, leading to a five-fold increase in CAR-T cell production, compared to the standard process.
