First-ever 3D view shows how killer T cells destroy cancer

Cytotoxic T lymphocytes act as the immune system's specialized "killer" cells, seeking out and eliminating infected or cancerous cells with remarkable precision. Their effectiveness depends on a tightly controlled contact point called the "immune synapse," where they release toxic molecules that destroy the target while leaving surrounding healthy cells unharmed. Until recently, scientists struggled to observe the fine structure of this process in detail. Now, researchers from the ...
