IL24 armored with CAR‐iNK cells showed enhanced proliferation and antitumor effect, and produced lower levels of IFN‐γ and GM‐CSF, which were correlated with a decreased risk of CRS and neurotoxicity compared to CAR19‐iNK cells, which might be safer following the prior reports and IL24 in lymphoma patients seems to be downregulated.24 This evidence concerns the gene CSF2 and lymphoma.
