Job description

Project information
The Peeper lab uses functional oncogenomic and other advanced technology to combat immunotherapy resistance. The introduction of ICB, most commonly in the form of CTLA-4 and PD-1 antibodies but also other therapies like TIL and CAR-T, has been clinically transformative.
However, most patients fail to respond (durably), often because of upfront or acquired resistance. Several resistance mechanisms have been described, including tumor cell-intrinsic and T cell-dependent ones. To develop therapeutic solutions, it is imperative that we understand the underlying mechanisms. Furthermore, given the diversity of this problem, there is a need to find specific solutions. Here, we focus on a therapeutic strategy to break tumor cell-intrinsic immune resistance.

We have recently uncovered a critical and conserved mechanism of tumor cell-intrinsic resistance involving TNF-mediated survival signaling. By genetic screening, we discovered that ablation of TRAF2, a key TNF signal transducer sharply lowered the tumor TNF cytotoxicity threshold, thereby augmenting tumor T cell- and ICB-impact in vitro and in preclinical murine models. Furthermore, loss of TRAF2 in patient tumors increases immune sensitivity, which was independently confirmed in a large-scale genetic analysis of clinical specimens. In this project, we focus on a druggable target in this pathway that we have discovered, aiming to not only understand its mechanism of action but also to explore clinical translation.
