Augmenting Immunotherapy Impact by Lowering Tumor TNF Cytotoxicity Threshold


ABSTRACT: Wild-type or TRAF2 mutated melanoma cells were treated with TNFalpha or co-cultured with activated T-cells for various short incubations (5min to 6 hours). Cells were harvested and analyzed using mass spectrometry for treatment induced changes at the proteome and phosphoproteome level.

New opportunities are needed to increase immune checkpoint blockade (ICB) benefit. Whereas the interferon (IFN)γ pathway harbors both ICB resistance factors and therapeutic opportunities, this has not been systematically investigated for IFNγ-independent signaling routes. A genome-wide CRISPR/Cas9 screen to sensitize IFNγ receptor-deficient tumor cells to CD8 T cell elimination uncovered several hits mapping to the tumor necrosis factor (TNF) pathway. Clinically, we show that TNF antitumor activ  ...[more]
