Expression data from Tregs purified from WT-CD3KO or IIKO-CD3KO chimeras

Project description:Disruption of TCR /MHC class II interactions leads rapidly to alterations of the common CD4 Treg transcriptional signature Self-deprived, non-functional Tregs were compare to fully functional Tregs by microarrays. CD3ε-/- mice were lethally irradiated and their immune system reconstituted with WT mouse (WT-CD3KO chimeras) or IIKO mouse (IIKO-CD3KO) Bone Marrow cells. Twenty eight days later, peripheral Tregs from these chimeras were purified for RNA extraction and hybridization on Affymetrix microarrays.

Expression data from self-deprived regulatory CD4 T cells

Project description:Disruption of TCR /MHC class II interactions leads rapidly to alterations of the common CD4 Treg transcriptional signature Self-deprived, non-functional Tregs were compare to fully functional Tregs by microarrays. Total T cells from the periphery of WT mice were adoptively transferred into CD3ε-/- recipient mice lacking or not MHC class II molecule expression (MHC II- or MHC II+ recipient mice, respectively). Five days later, peripheral Tregs transferred in MHC II - competent (CD4CD25B6) or - deficient (CD4CD25IIko) recipient were purified for RNA extraction and hybridization on Affymetrix microarrays.

IL-2 therapy preferentially expands adoptively transferred donor-specific Tregs improving skin allograft survival.

Project description:Regulatory T cells (Tregs) have unique immunosuppressive properties and are essential to ensure effective immunoregulation. In animal models, Tregs have been shown to prevent autoimmune disorders and establish transplantation tolerance. Therefore, the prospect of harnessing Tregs, either by increasing their frequency or by conferring allospecificity, has prompted a growing interest in the development of immunotherapies. Here, employing a well-established skin transplant model with a single major histocompatibility complex mismatch, we compared the therapeutic efficacy of adoptively transfer Treg with or without donor specificity and the administration of IL-2 to promote in vivo expansion of Treg. We showed that IL-2 treatment preferentially enhances the proliferation of the allospecific Tregs adoptively transferred in an antigen-dependent manner. In addition, donor-specific Tregs significantly increased the expression of regulatory-related marker, such as CTLA4 and inducible costimulator (ICOS), in the skin allograft and draining lymph nodes compared to endogenous and polyclonal transferred Tregs. Importantly, by combining IL-2 with donor-specific Tregs, but not with polyclonal Tregs, a synergistic effect in prolonging skin allograft survival was observed. Altogether, our data suggest that this combination therapy could provide the appropriate conditions to enhance the immunoregulation of alloimmune responses in clinical transplantation.

Single cell RNAseq of adoptively transferred Tregs in rhesus macaques

Project description:Animal R.401 was infused with ex-vivo expanded T-regulatory cells. After adoptive transfer, PBMC were obtained and stained with surface antibodies. Single cell libraries from sorted populations were generated using a UMI-based droplet-partitioning platform (10X Genomics) and sequenced using a NextSeq 500 (Illumina). Resulting reads were processed using Cellranger software (10X Genomics) and downstream analysis was performed using Monocle6,7 using a negative binomial model of distribution with fixed variance.

Cyclosporine A but Not Corticosteroids Support Efficacy of <i>Ex Vivo</i> Expanded, Adoptively Transferred Human Tregs in GvHD.

Project description:Reshaping the immune balance by adoptive transfer of regulatory T-cells (Tregs) has emerged as a promising strategy to combat undesired immune reactions, including in Graft-versus-Host Disease (GvHD), which is the most lethal non-relapse complication of allogeneic hematopoietic stem cell transplantation. Currently however, little is known about the potentially inhibitory in vivo effects of conventional immunosuppressive drugs, which are routinely used to treat GvHD, on adoptively transferred Tregs. Here we demonstrate drug-specific effects of the conventional immunosuppressive drugs Cyclosporine A, Mycophenolate mofetil and methylprednisolone on adoptively transferred Tregs in a humanized NOD/SCID/IL2Rgamma-/- GvHD mouse model. The clinical course of GvHD and postmortem organ histology, including cellular organ infiltration, showed that co-administration of Cyclosporine A and Tregs is highly beneficial as it enhanced Treg accumulation at inflammatory sites like lung and liver. Similarly, co-administration of Mycophenolate mofetil and Tregs improved clinical signs of GvHD. In contrast, co-administration of methylprednisolone and Tregs resulted in reduced Treg recruitment to inflammatory sites and the fast deterioration of some animals. Consequently, when clinical trials investigating safety and efficacy of adjunctive Treg therapy in GvHD are designed, we suggest co-administering Cyclosporine A, whereas high doses of glucocorticosteroids should be avoided.

Proteomic analysis of rest and activated Tregs

Project description:The aim of the project is to do proteomic analysis of total cell lysate from rest and activated mouse Tregs. The proteomic data were mapped to the Gene Ontology Cellular Component (GOCC)database to obtain the list of membrane proteins on activated Tregs. The set of membrane proteins identified were compared with the potential Siglec-1 counter-receptors on activated Tregs.
