Summary from the GEO: "We analyzed open chromatin regions in thymic Treg cells, their immediate precursors (CD25+ Foxp3-), and mature and semi-mature CD4 single positive cells. We wished to understand which chromatin regions become accessible in response to TCR-stimulation and then Foxp3 expression as Treg cells develop. Examination of chromatin accessibility in developing CD4SP thymocyte subsets,...

Summary from the GEO: "Immune checkpoint blockers (ICBs) have failed in all phase III glioblastoma (GBM) trials. Here, we show that regulatory T (Treg) cells play a key role in GBM resistance to ICBs in experimental gliomas. Targeting glucocorticoid-induced TNFR-related receptor (GITR) in Treg cells using an agonistic antibody (αGITR) promotes CD4 Treg cell differentiation into CD4 effector T cells,...

Summary from the ENA: "Antibiotic exposure early in life, and other practices impacting the vertical transmission and ordered assembly of a diverse and balanced gut microbiota, are associated with a higher risk of immunological and metabolic disorders such as asthma and allergy, autoimmunity, obesity, and susceptibility to opportunistic infections. Here, we use a model of perinatal exposure to the...

Summary from GEO: "Regulatory T (Treg) cells expressing the lineage-defining transcription factor Foxp3 are essential for the maintenance of immune tolerance. Foxp3 expression can be induced in a subset of developing self-reactive thymocytes to yield thymic Treg (tTreg) cells, critical for tolerance against self-antigens. Alternatively, activation of mature naïve T cells under non-inflammatory conditions...

Summary from GEO: "The aim of the study was to compare gene expression between Treg cells in the bone marrow and the spleen." Overall design from GEO: "2 male Foxp3-DTR-GFP were used for the study. Single cells suspension from BM and spleen were prepared, then enriched for CD4 by magneic beads and sorted by gating on CD4+TCRb+. GFP was used to differentiate between Tregs and CD4conv. CD4conv...

Summary from GEO: "Although allogeneic hematopoietic cell transplantation (allo-HCT) is curative for high-risk pediatric acute myeloid leukemia (AML), disease relapse remains the primary cause of post-transplant mortality. To identify pressures imposed by allo-HCT on AML cells that escape the graft-versus-leukemia effect, we evaluated immune signatures in bone marrow samples from four pediatric patients...

Summary from GEO: "Based on RNA-seq technology, we studies gene expression profiles in Treg cells isolated from mouse tumors and spleens. We identified differential gene expressions comparing OX40hi Treg with OX40lo Treg cells from tumors and spleens. The difference of Trges in tumors and spleens were also identified." Overall design from GEO: "Foxp3-GFP mice were intradermally implanted with...

Summary from GEO: "Tolerance to self- or innocuous foreign antigens is vital for preservation of organismal health. Within the thymus, medullary thymic epithelial cells (mTECs) expressing AutoImmune Regulator, Aire, play a critical role in self-tolerance through deletion of autoreactive T cells and promotion of thymic regulatory T (Treg) cell development. A second wave of Treg cell differentiation...
