Full textChronic GVHD (cGVHD) remains a major complication of allogeneic stem cell transplantation and its pathogenesis poorly understood. Previous reports established the role of T cells and B cells during cGVHD, but the quality of their interaction and T cell subsets involved remain to be defined. T cell – B cell crosstalk occurs in the germinal center generating memory B cells and high affinity antibody secreting cells consecutively to signals provided by T follicular helper cells (TFH) which are tightly controlled by a regulatory subset (TFR). The opportunity to interrogate events occurring in the germinal center through the analysis of their circulating contingent (c), allowed us to better understand cGVHD pathogenesis. cTFH phenotypic signature suggest an enhanced function during cGVHD, confirmed in functional studies, and correlating with observed B cell phenotype. In addition, regulatory mechanisms appeared defective during cGVHD, as cTFR showed a numerical deficiency, explained by a defect in resistance to apoptosis and low proliferative capacity. We also studied a T cell subset expressing CD4+CD146+CCR5+, giving the capacity to migrate through endothelial structures and toward inflammatory sites. This population is significantly increased during cGVHD, and cGVHD murine models receiving splenocytes from CD146-/- mice showed improved clinical score. CD146 expression is associated with a Th17 polarization justifying a treatment by TMP778 (RORγt inhibitor) improving cGVHD in mice. The analysis of these different populations revealed an abnormal effector-regulator balance and potential therapeutic targets to evaluate in clinic

Full textAllogeneic hematopoietic stem cell transplantation (HSCT) remains the only curative treatment for many patients with haematological malignancies. In almost half of the cases, it is complicated by chronic graft-versus-host disease (cGVHD). Regulatory B cells are a population of B cells secreting interleukin (IL)-10 that can inhibit the immune responses. We have shown that in patients with active cGVHD, the frequency of regulatory B cells is decreased in the peripheral blood. Regulatory B cells are enriched in the memory B cell and plasmablast B cell pools. Increased plasmablasts frequencies and decreased memory B cells frequencies were found in patients with active cGVHD, suggesting alterations in the terminal differentiation of B cells. Our work also focused on NK cells that have a cytotoxic role. We identified one surface receptor of NK cells, CD245, as myosin 18A. Myosin 18A is involved in the organization of the cytoskeleton and is a receptor of the surfactant A. We have shown that myosin 18A was a coactivating receptor of the NK cytotoxicity and that this increase in cytotoxicity could be linked to the stimulation of the expression of CD137 (4-1BB) on the surface of the NK lymphocyte. These results suggest a potential therapeutic role of the use of specific CD245 agonist antibodies

Full textGraft versus host disease (GVHD) is the primary cause of mortality and morbidity following hematopoietic stem cell transplantation. Many patients remain refractory to current treatments, emphasizing the need to develop new therapeutic strategies. In the present study, we have used a novel therapeutic agent, TH9402, and shown that once activated by visible light (514 nm), this photosensitizer becomes specifically cytotoxic toward activated T cells while preserving resting T cells and regulatory T cells (Tregs). Preserved Tregs can display anti GVHD activity through IL-10 and CTLA-4 dependent mechanisms. Furthermore, CTLA-4 signaling was associated with an increased Treg population. This increase resulted from FOXP3 induction in CD4+CD25- cells and not selective proliferation of Tregs. In the second part of this study, we showed that CTLA-4 signaling was associated with enhanced expression of indoleamine 2,3 dioxygenase (IDO). The expression of IDO results in the generation of anti GVHD activity and an increase in the Treg population following TH9402 treatment. This increased Treg population was mediated by tryptophan degradation and implied acute phase protein GCN2 activity. Finally, we show that the infusion of TH9402 treated cells in patients suffering from chronic GVHD resulted in an increase of the Treg population as early as 8 weeks after treatment initiation without causing lymphopenia or hyporesponsiveness toward viral antigens. Furthermore, the increase of IDO corresponded to patient response to treatment. These results suggest that TH9402 represents a most interesting therapeutic approach for patients with refractory chronic GVHD. IDO expression could also be used to predict patient responsiveness to the treatment. This could increase the quality of the treatment as well as the quality of life of patients suffering from refractory chronic GVHD.
