Immuno-Biology & Immuno-Oncology
Our research, based on Cellular and Molecular Immunology, chases fundamental questions related to the biology of white blood cells (leukocytes), such as:
- How do leukocytes develop and differentiate into immune effectors?
- What is the contribution of the various leukocyte populations to tumor progression?
- What roles do leukocytes play in tissue (patho)physiology, including upon infection?
- What are the functional implications of having leukocytes in the brain meninges?
In our Immuno-Oncology research line, we are particularly interested in T cells and macrophages, which are key players in the tumor microenvironment (TME). We study their cellular and molecular crosstalks within the TME, trying to boost anti-tumor mechanisms (based on cytotoxicity and interferon-gamma secretion) over pro-tumor effects (linked to inflammation and angiogenesis). Moreover, we have applied seminal knowledge we produced on gamma-delta (γδ) T cells onto the development of a new methodology for adoptive cell therapy of cancer – Delta One T (DOT) cells – within a spin-off company, Lymphact SA, acquired in 2018 by GammaDelta Therapeutics (London, UK). We continue to study DOT cells, their functional regulation and their molecular mechanisms of tumor cell recognition, in tight collaboration with GammaDelta Therapeutics.
In a more fundamental Immuno-Biology research line, which has been funded by the European Research Council (ERC) over the past decade, we strongly focus on gamma-delta (γδ) T cells as to better understand their differentiation and functions. Our projects range from their thymic development and effector cell differentiation, to the dissection of the functional roles in peripheral immune responses to pathogens such as Plasmodium (malaria), or their contribution to brain (patho)physiology in health (cognition) and disease (neurodegeneration).
