Project description
Insight into lymph node biology
Lymph nodes (LN) are small organs found throughout the body that play a vital role in the immune system by filtering lymph fluid and trapping pathogens. LN stromal cells form the supportive framework of LNs, controlling the movement, activation, and survival of lymphocytes. Funded by the European Research Council, the STROMA project is interested in understanding the biology of LN stromal cells because of their essential role in immune system regulation. Researchers propose to develop advanced mouse models and computational approaches to track the fate of individual stromal cells in their natural environment. The aim is to uncover their spatiotemporal behaviour during inflammation and provide valuable insights into LN stromal cell development and remodelling.
Objective
In 1984, Nossal wrote ‘‘A readership consisting of primarily anatomists has every right to question the favorite sport of research workers in cell immunology. This is to take a lymphoid tissue and totally destroy its beautiful and elaborately designed architecture to obtain simple cell suspension of lymphocytes, which are then asked to do more or less all the jobs of the original anatomic masterpiece’’. Growing evidence that lymph node (LN) stromal cells control the motility, activation and survival of lymphocytes has reinforced this view. These architectural cells assemble in 3D networks that regulate LN homeostasis and control its ability to remodel during inflammation. Understanding stromal cell biology is thus mandatory to our full comprehension of the immune system but this ambitious objective is technically challenging. As the complexity of the LN cannot be modelled in culture, knowledge gained from in vitro experiments is limited and will not address many relevant questions related to the biology of LN stromal cells, in particular (i) the elucidation of their origin and the precursor/product relationships that link them, (ii) the determination of their behavior in inflamed LNs and (iii) their subsequent fate in LNs that have returned to homeostasis. To this aim, I have developed several original, cutting-edge multicolor fluorescent reporter mouse models and computational modeling approaches to map the fate of single stromal cells and their progeny in situ. Using this innovative approach, my group will investigate the spatio-temporal behavior and molecular cues that orchestrate the development and dynamics of the major LN stromal cell populations in vivo, at steady state and under inflammatory conditions, at the single cell level. Because the proposed studies will unravel the precursor/product relationships linking the various stromal cell types, we anticipate to provide the first “Phylogenetic tree” of LN stromal cell development and remodeling.
