A nano-engager for iNKT cells in cancer

Invariant natural killer T cells (iNKT cells) are innate-like CD1d-restricted T cells that have NK cell–like properties and bear an invariant T cell receptor (iTCR). iNKT cells have shown potential for cancer immunotherapy. A study now shows that stabilization of the iTCR–CD1d complex via a single-chain bi-specific antibody stimulates iNKT cell–mediated anti-tumor immunity.
