Novel targets to improve allogeneic hematopoietic stem cell transplantation
B cells are pivotal in chronic graft-versus-host disease (cGVHD), which is the most common cause of late non-relapse morbidity and mortality after allogeneic hematopoietic stem cell transplantation. Recent single-cell RNA-sequencing studies demonstrated that AIM2 (absent in melanoma 2) is upregulated in cGVHD patient B cells. Upon DNA binding, the AIM2 protein induces AIM2 inflammasome formation and triggers pro-inflammatory cytokine secretion. Other related studies showed that the enzyme DNase1L3 regulating extracellular DNA exposure could play a pivotal role in B cell development. The EU-funded DABAT project will investigate AIM2 and DNase1L3 in human B cells and in mouse in vivo models. The research will address intrinsic molecular programmes underpinning B cell pathobiology and agents targeting B cells which can be developed for cGVHD treatment.
