Postdoc vacancy in Peeper Lab for ERC Advanced project

Function description

Reversing T cell dysfunction in cancer by multimodal genetic screening

The Netherlands Cancer Institute (NKI) Located in Amsterdam, NKI is an internationally renowned institute dedicated to fundamental, translational and clinical cancer research, and the only comprehensive cancer center in The Netherlands. It is a dynamic institute accommodating over 50 research groups and many advanced core facilities, including flow cytometry, proteomics, genomics, biobank and a mouse cancer center.

Project information T cell dysfunction is a key problem in cancer, enabling not only tumorigenesis but also causing resistance to immunotherapy. A better mechanistic understanding is imperative for improving immunotherapy. We recently received an ERC Advanced grant for “ReverT”, a function-based genetic CRISPR-Cas9 screening program to identify genes, ablation of which reverses T cell dysfunction in vivo. This will be done in a pooled and multimodal fashion, analyzing multiple dysfunction phenotypes in parallel, like immune checkpoints, exhaustion, metabolism, recruitment and proliferation. We have already identified several exciting candidates, including “nodal” factors, operating in several seemingly different dysfunction settings. We will use a collection of ex patient tumor models for validation and mechanistic characterization. Lastly, we will translate our findings to a preclinical setting, aiming to achieve more durable clinical responses.
