A protein called TRAILshort may act as a central immune brake that limits T-cell responses and CAR-T therapy. Cancer cells can weaken the immune system by producing a protein that prevents its most important defenders from attacking. Mayo Clinic researchers have identified how this protein works, revealing a possible target for treatments designed to improve [...]

T cells may use a previously unknown CD64-dependent pathway to attack acute myeloid leukemia. T cells are generally thought to identify cancer through a well-established molecular recognition system. Yet when researchers removed a key part of that system from acute myeloid leukemia (AML) cells, the immune cells continued killing them. The unexpected result led scientists [...]
