Additionally, NK cells infiltrating Axl KO tumors displayed enhanced cytotoxicity as shown by increased production of cytotoxic proteins, including IFN-gamma and granzyme B. Importantly, the delayed tumor growth observed in Axl KO tumors was reversed upon NK cell depletion, underscoring the pivotal role of NK cells in mediating this effect. The gene discussed is IFNG; the disease is neoplasm.
