T lymphocytes, which are a subtype of white blood cell, play a central role in cell-mediated immunity. They are distinguished from other lymphocytes, such as B cells and natural killer (NK) cells, by the expression of a T cell receptor (TCR) on the cell surface. Team 1 has been working for decades on the immunobiology of human T lymphocytes that express either αβ or γδ TCR. The team was made of three subgroups which addressed complementary issues dealing with the immunobiology of human T lymphocytes and their immunotherapeutic use against infections and cancers.

In line with recent observations made by the team and its unique expertise that was recently strengthened by additional members and clinicians, our joint objectives are to pursue from a fundamental standpoint the analysis of the specificity and function(s) of human T lymphocyte subsets (e.g., αβ/γδ T and NK cells) and the impact of selected interleukins, such as IL-15, in physiopathological contexts. From both preclinical & clinical standpoints, the research work focuses on:
(i) the ways to optimize immunotherapies targeting human lymphoid subsets (e.g., development of orthotopic in vivo models);
(ii) the analysis of alloreactive T lymphocyte responses elicited along allograft transplantation, in relation with both clinical status and allograft outcome in patients;
(iii) the design of novel in vitro tools for medium-throughput screening approaches of lymphoid cell-mediated reactivities induced by therapeutic antibodies;
(iv) the biology of IL-15 and its therapeutical applications.
