Descripción del proyecto A recent paradigm shift is that B cells are pivotal in chronic graft-versus-host-disease (cGVHD), which is the most relevant cause of late non-relapse morbidity and mortality after allogeneic haematopoietic stem cell transplantation. DABAT’s project hypothesis is that 1) DNA-sensing by AIM2 supports cGVHD pathological B cells through autocrine regulations and that 2) their DNase1L3 expression modulates DNA-sensing by AIM2. Doctor Sarantopoulos (Duke University, US, supervisor for the outgoing phase) recently performed a single cell RNA-Sequencing experiment showing that AIM2 is upregulated in cGVHD patient B cells. Upon DNA binding, the AIM2 protein induces AIM2 inflammasome formation that triggers pro-inflammatory cytokines secretion. The survival and function of pathological B cells in cGVHD seem to be based on similar mechanisms to those of marginal zone (MZ) B cells. Doctor Sisirak (Bordeaux University, France, supervisor for the incoming phase) showed that DNase1L3, a major enzyme regulating extracellular DNA exposure, could play a pivotal role in MZ B cells development. The researcher will conduct the DABAT project under the supervision of these two internationally recognized experts in cGVHD B cells and DNase1L3. He will study AIM2 and DNase1L3 in human B cells and in mouse models. This fellowship will provide him with advanced technical training in B cell studies, flow cytometry, transcriptomic, histopathology and animal handling. He could identify intrinsic molecular programs underpinning B cell pathobiology, so that agents targeting B cell can be developed to treat cGVHD. He will be the main spokesperson of the project to a large audience. This fellowship will be a crucial step to extend his knowledge, to develop his communication, management and leadership skills, and to enlarge his international professional network. He will then become a mature and independent researcher enriching EU expertise and networking in Immunology and Transplant Immunology.
