TNF and leukemia: The expanded T cells from patient SH7152 (CMML), that recognized HLA-A02:01-restricted peptides SLVSKVWHKV (ERVE-3) and FLLTSFTTGRV (ERVS71-1) (Fig. 2b and Table 1), showed increased cytokine production (IFN-γ and TNF-α) and degranulation (CD107a) upon incubation with HLA-matching leukemia cell line THP-1, but not when THP-1 cells were blocked with anti-HLA-A antibodies (Fig. 4b).
