In the long human struggle against blood cancers, science has found a new ally in iNKT cells — immune sentinels that bridge the body's instinctive and learned defenses. Researchers publishing in Nature have shown that by carefully engineering these cells with optimized CAR structures, and pairing them with a purpose-built molecular engager, it becomes possible to attack multiple myeloma from two directions at once — closing the escape routes that have long allowed this cancer to outlast treatment. The work is a reminder that resilience in medicine, as in life, often comes not from a single pow
