Engineered T cells Flt around their targets

Antigen escape by solid tumors has limited the efficacy of genetically modified T cells. T cells engineered to secrete the cytokine Flt3L induce the activation of endogenous T cells, enabling a broader repertoire of tumor antigens to be targeted via the expansion of intratumoral antigen presenting cells, significantly improving tumor responses.
