Since the majority of MHC class II expression in RNAseq data from melanoma samples is derived from APCs [48] and tumor-infiltrating APCs are generally GILT and MHC class II positive (current study and [31]), there is a need to assess GILT and other MHC class II pathway components in specific cell types, such as tumor cells, as performed in the current study. This evidence concerns the gene IFI30 and melanoma.
