Technician in Peeper Lab for NWO XL project

Function description

Defining the functional T cell:Tumor interactome

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
A functional immune defense against cancer depends on many parameters, including specific physical and dynamic contacts between cytotoxic CD8+ T cells and tumor cells, triggering numerous signaling events between and within these cell types. Whereas disruptions in T cell:tumor cell interactions contribute to immune evasion and cancer, pharmacologic intervention of interactions like PD-1:PD-L1 has significant clinical benefit. Interactions between CD8+ T cells and other immune cells have been well-characterized, but we lack a detailed map of functional interactions between CD8+ T cells and tumor cells. We hypothesize that high-resolution mapping and functional dissection of the T cell:tumor cell interactome will both provide new insight into the underlying mechanism and signaling events and identify novel pharmacologic targets to improve immunotherapy.

Together with co-PIs Karin de Visser (in vivo tumor suppression by immune cells, NKI) and Maarten Altelaar (proteomics, Utrecht), we recently received a 3M€ NWO-XL grant to study these questions. We have already established several mouse and human T cell:tumor cell co-cultures and humanized and syngeneic mouse models, which will be applied and expanded.

Job requirements

An ambitious technician with mouse model experience.
We seek an enthusiastic and accurate animal technician. It is strictly necessary that you hold a license for working with laboratory animals (art. 6/9/12). You should also have expertise in immunology and/or molecular biology. You will be responsible for carrying out animal experiments in collaboration with researchers on this project. Furthermore, you will contribute to wet-lab experiments and contribute to some lab management tasks. Proficiency in English and good communicative skills are important requirements, as is a team player mentality.



The vacancy is available this Fall. You will be employed for a minimum period of 2 years, with the possibility for extension. The gross salary per month can range from € 2.554,- to € 3.468,- (salary scale 45 according to the Collective Labour Agreement General Hospitals based on proven qualifications). The terms of employment will be in accordance with the CAO Hospitals and includes an end-of-year bonus and holiday pay. Acquisition for this vacancy is not appreciated.
