Contenu scientifique du programme de la thèse (en anglais)
Rudolf Virchow postulated more than 150 years ago that inflammation might be linked to cancer
development. Although a large body of experimental evidence accumulated to date strongly supports
such a link, it is less clear whether the immune system plays a beneficial or detrimental role in this
process. Innate lymphoid cells (ILCs), including natural killer cells, are a diverse family of hematopoietic
effectors that rapidly produce cytokines and can play anti- or pro-inflammatory roles in infection,
transformation and tissue homeostasis. The roles for NK cells in the anti-tumor response are well
described, however, the impact of other ILC subsets in cancer immunology remains less defined.
This project aims at identifying novel genetic traits that regulate the anti-tumor activities of NK
cells and other ILC using an unique mouse resource, the Collaborative Cross (CC). CC is a panel of
recombinant inbred mice derived from randomized breeding of eight laboratory inbred strains combining
high genetic diversity with the advantage of inbred mouse strains. We have identified CC strains that
diverge in their anti-tumor immune responses and are characterizing the molecular mechanisms
responsible for these differences. Ultimately, these diverse genetic traits may lead to the development of
novel therapies for cancer.
The practical part of this project involves molecular and cellular methodology and state-of-the-art
equipment and technologies as well as bioinformatical analyses.
This project is funded by La Ligue National Contre le Cancer. We are seeking outstanding PhD students for
this project.
