In a melanoma mouse model, dabrafenib significantly increased the infiltration of CD8+ T cells, and trametinib in BRAF wild-type tumor cells appears to upregulate human leukocyte antigen (HLA) molecule expression while downregulating certain immunosuppressive factors such as PD-L1, IL1, IL8, CD73, and vascular endothelial growth factor A (VEGFA) [72]. This evidence concerns the gene BRAF and neoplasm.
