IFNG and neoplasm: Analysis of treated tumors revealed significantlyhigher MHC-Iexpression on tumor cells with both 4-1BBL/IL-12 NPs and 4-1BBL/IL-12/IFNγNPs as well as 4-1BBL/IL-12 NPs with anti-PD1 in vivo, and there was a trend toward higher MHC-I expression in the grouptreated with 4-1BBL/IL-12/IFNγ NPs and anti-PD-1.
