First-ever 3D view shows how killer T cells destroy cancer
Scientists have captured the first 3D view of how killer T cells precisely target and destroy cancer cells within real tumors using advanced cryo-expansion microscopy. The imaging reveals detailed structural features of the immune synapse and cytotoxic granules, showing how these immune cells minimize damage to surrounding healthy tissue. This breakthrough provides new insights into the molecular organization of T cell activity and could enhance immuno-oncology research.
