Project description:Graft versus host disease (GVHD) is the most common complication of hematopoietic stem cell transplant (HCT). However, our understanding of the molecular pathways that cause this disease remains incomplete, leading to inadequate treatment strategies. To address this, we measured the gene expression profile of non-human primate (NHP) T cells during acute GVHD. In this study we specifically interrogated the transcriptional signatures of animals treated with FR104 monotherapy and FR104/Sirolimus combination therapy

Project description:Graft versus host disease (GVHD) is the most common complication of hematopoietic stem cell transplant (HCT). However, our understanding of the molecular pathways that cause this disease remains incomplete, leading to inadequate treatment strategies. To address this, we measured the gene expression profile of non-human primate (NHP) T cells during acute GVHD. This transcriptome analysis enables an unsupervised approach to the identification of targets for disease control using a model with an immune system that closely overlaps with the human and has a high degree of cross-reactivity with human antibody-based therapeutics.

Project description:Graft versus host disease (GVHD) is the most common complication of hematopoietic stem cell transplant (HCT). However, our understanding of the molecular pathways that cause this disease remains incomplete, leading to inadequate treatment strategies. To address this, we measured the gene expression profile of non-human primate (NHP) T cells during acute GVHD (GSE73723). Within these profiles we discovered potentially druggable targets not previously implicated in GVHD, prominently including aurora kinase A (AURKA). In this study, we performed a planned comparison of AURKA gene expression in HCT-recipients with clinical GVHD and compared it to expression in HCT-recipients without clinical GVHD.

Project description:Rapid CD137 upregulation on alloreactive T-cells upon allogeneic stimulation suggests that their selective elimination could prevent acute graft-versus-host disease (aGVHD) after allogeneic hematopoietic stem cell transplantation (HCT). Here, we developed a novel aGVHD prophylactic regimen consisting of a single dose of an anti-CD137 antibody-drug conjugate (CD137-ADC) administered on the day of transplant without additional immunosuppression. The CD137-ADC depleted both human and non-human primate (NHP) activated T-cells and proved highly effective in preventing xenogeneic aGVHD in mice receiving human peripheral blood mononuclear cells (PBMC), as well as in NHP undergoing MHC-haploidentical HCT. Flow cytometry analysis of NHP T-cells indicated specific depletion of activated PD-1+ CD4 and CD8 T-cells, while sparing naïve and PD-1-OX40+ memory T-cell subsets during the first week after HCT. CD137-ADC-treated NHP recipients demonstrated robust hematopoietic and immune reconstitution. Hallmarks of T-cell recovery after CD137-ADC, which were associated with long-term aGVHD-free survival, included reconstitution of CD4 memory T-cells expressing TRAIL, terminally-differentiated CD8 T-cells expressing CX3CR1, and CD4 FoxP3+ Tregs – cell types not expected to be involved in aGVHD pathogenesis. CD137-ADC-treated recipients demonstrated a higher risk of reactivation of rhLCV (the rhesus macaque EBV analogue), which was associated with reconstitution of follicular helper T-cells, interferon signaling-associated memory, and gamma-delta T-cell subsets. This reactivation was controllable with rituximab administration. These results document effective depletion of alloreactive T-cells and prevention of aGVHD following a single dose of CD137-ADC, suggesting that clinical translation should be carefully explored.

Project description:Tissue-specific T cell immune responses play a critical role in maintaining organ health, but can also drive immune pathology during both auto- and alloimmunity. The mechanisms controlling intra-tissue T cell programming remain unclear. Here, we leverage a non-human primate model of acute graft-versus-host disease (aGVHD) after allogeneic hematopoietic stem cell transplantation (HCT) to probe the biological underpinnings of tissue-specific alloimmune disease, using a comprehensive systems immunology approach.Transcriptional profiling revealed substantial biological differences between T cells, infiltrating the lung and liver during aGVHD.
