IFN-γ is a central regulatory cytokine in the initiation and maintenance of aGVHD due to its crucial function for CD4 + Th1 cells differentiation and CD8 + T cells function during the priming and expansion phase ( 6). In GVHD, the donor T cells recognize the host antigens, activate, differentiate and traffic to the target organs under guidance of cytokines and chemokines, and result in inflammatory damages in the target organs ( 5). Alloreactive T cells were the major detrimental factors during the pathogenesis of aGVHD ( 3, 4). In summary, our results indicate LYG1 regulates aGVHD by the alloreactivity of CD4 + T cells and the balance of Th1 and Treg differentiation of allogeneic CD4 + T cells, targeting LYG1 maybe a novel therapeutic strategy for preventing aGVHD.Īcute graft- versus-host disease (aGVHD) is medical complication which mainly destroy host tissues including the skin, liver, colon and the lung after allogeneic hematopoietic cell transplantation (allo-HSCT), representing a major cause for morbidity and non-relapse mortality ( 1, 2). Furthermore, LYG1 deficiency in donor T cells preserved graft-versus-tumor response. The effect of rhLYG1 could partially be abrogated with the absence of IFN-γ. Furthermore, administration of recombinant human LYG1 protein intraperitoneally aggravated aGVHD by promoting IFN-γ production and inhibiting FoxP3 expression.
The function of LYG1 in aGVHD was also confirmed using haploidentical transplant model. By using major MHC mismatched aGVHD model, LYG1 deficiency in donor T cells or CD4 + T cells attenuated aGVHD severity, inhibited CD4 + T cells activation and IFN-γ expression, promoted FoxP3 expression, suppressed CXCL9 and CXCL10 expression, restrained allogeneic CD4 + T cells infiltrating in target organs. LYG1 deficiency reduced the activation of CD4 + T cells and Th1 ratio, but increased Treg ratio in vitro by MLR assay. In this study, we characterized the role of a previously identified novel classical secretory protein with antitumor function-LYG1 (Lysozyme G-like 1), in aGVHD. The mechanism involves the recognition of host antigens by donor-derived T cells which induces augmented response of alloreactive T cells.
