Columbia researchers created super-sensitive CAR T cells that wiped out solid tumors in mice by targeting low-level CD70, offering hope for hard-to-treat cancers.
Researchers at Columbia University have developed ultra-sensitive CAR T cells, called HIT receptors, that successfully eradicated kidney, ovarian, and pancreatic tumors in mice by targeting CD70, a protein present at very low levels on solid tumor cells.
Unlike conventional CAR T cells, these engineered cells detect minimal CD70 expression, enabling them to eliminate cancer cells previously missed, including those deemed CD70-negative.
The therapy, which spares healthy tissues, shows promise for treating a range of solid tumors resistant to current immunotherapies.
The team plans to seek funding for human trials, with potential applications in nearly 20 cancer types.
