Project description:Mucosal-associated invariant T (MAIT) cells, the most abundant unconventional T cells in the lung, have been recently linked to tissue protection and repair. Their role, especially in sterile lung injury, is unknown. Using single cell RNA sequencing (scRNA-seq), spectral analysis and adoptive transfer in a bleomycin-induced sterile lung injury, we found that bleomycin activates murine pulmonary MAIT cells and induces an accompanying tissue repair programme, associated with a protective role against bleomycin-induced lung injury. MAIT cells drive the accumulation of type 1 conventional dendritic cells (cDC1), limiting tissue damage in a DNGR-1 dependent manner. Human scRNA-seq data revealed that MAIT cells were activated, with increased cDC populations in idiopathic pulmonary fibrosis patients. Thus, MAIT cells enhance defence against sterile lung injury by fostering cDC1-driven anti-fibrotic pathways.

Project description:Mucosal associated invariant T (MAIT) cells, already differentiated and located at mucosal sites, are critical in the body’s first wave of defenses against invading pathogens. Bcl11b KO MAIT cells fail to be maintained both in the thymus and peripheral organs. Furthermore, MAIT cells fail to fully develop in the thymus without Bcl11b, failing to upregulate RORγt, and that phenotype remains in the lungs and livers of these mice. Bcl11b deletion in MAIT cells causes dramatic shifts in the activation and TH17 programs, due to the binding of Bcl11b in many of those genes, which we have seen in the human MAIT cells. MAIT cells rely on PLZF and RORγt for their development and function, while also heavily relying on Bcl11b. These data show the key interplay of Bcl11b with PLZF and RORγt in a T cell leading to its development and necessary function to protect the body against diseases.

Project description:Lung ischemia-reperfusion (I/R) injury remains one of the common complications after various cardiopulmonary surgeries. I-R injury represents one potentially maladaptive response of the innate immune system which is featured by an exacerbated sterile inflammatory response triggered by tissue damage. Thus, understanding the key components and processes involved in sterile inflammation during lung I-R injury is critical to alter care and extend survival for patients with acute lung injury.
