Cancer-Fighting Immune Cells Could Soon Be Engineered Inside Our Bodies
Researchers are developing techniques to genetically modify cancer-fighting immune cells directly inside patients rather than in expensive laboratory facilities, potentially making CAR-T therapy accessible to far more people.

Researchers are developing techniques to genetically modify cancer-fighting immune cells directly inside patients rather than in expensive laboratory facilities, potentially making CAR-T therapy accessible to far more people.Current CAR-T treatments require removing a patient's T cells, shipping them to specialized facilities for genetic engineering, then returning them weeks later at costs around $500,000 per dose. The new "in vivo" approaches use viral vectors or RNA-loaded nanoparticles to deliver genetic instructions directly to T cells circulating in the bloodstream, which could reduce costs by an order of magnitude. Companies including Capstan Therapeutics, co-founded by Nobel laureates, and AstraZeneca-backed EsoBiotec have launched early human trials.
