Selective targeting of malignant T cells.

Targeted therapies that use small-molecule inhibitors for the treatment of T cell blood cancer exist only for certain subtypes, and the development of immunologically based CAR T cell therapies has been challenging. A study now exploits the fact that malignant T cells express one of two T cell receptor-β variants and investigates strategies for targeting these malignant cells while sparing half of the non-malignant T cells.
