MetabolomicsLoss of p53 exacerbates autoimmunity by reprogramming propionyl-CoA metabolism and epigenetics in Treg cells

Metabolic regulation is central to the tumor suppressor function of p53. Here we report that propionyl-CoA metabolic remodeling and epigenetic changes underpin p53-mediated restraint of autoimmunity through regulatory T (Treg) cells. By analyzing the human patients with autoimmune diseases, we fo...

MetabolomicsPolyamines regulate adaptive antitumor immunity by functional specialization of regulatory T cells

In cancer, metabolic changes and uncontrolled tumor growth alter nutrient availability, impacting antitumor immune responses. Regulatory T (Treg) cells are a subset of T cells with immunosuppressive properties that has been found to additionally possess the ability to control tissue homeostasis a...

MetabolomicsRegulatory T cells promote endurance exercise adaptation by shielding muscle mitochondria from damage

Exercise enhances physical performance and reduces the risk of many disorders such as cardiovascular disease, type 2 diabetes, dementia and cancer. Exercise characteristically incites an inflammatory response, notably in skeletal muscles. While some effector mechanisms have been identified, regul...

TranscriptomicsmiRNA expression in CD4+CD25- conventional (Tconv) and CD4+CD25+ regulatory T (Treg) cells
miRNA expression profiling in highly purified murine CD4+ Tconv and Treg cells. FoxP3-GFP-hCre1a(high) reporter mice were used to separate both populations based on surface markers and presence or absence of GFP. Two-condition experiment, Tconv vs. Treg. Biological replicates: 1 Tconv, 1 Treg, purif...

MetabolomicsAMPK activation induces RALDH+ tolerogenic dendritic cells by rewiring glucose and lipid metabolism.
Dendritic cell (DC) activation and function are underpinned by profound changes in cellular metabolism. Several studies indicate that the ability of DCs to promote tolerance is dependent on catabolic metabolism. Yet the contribution of AMP-activated kinase (AMPK), a central energy sensor promoting c...

ProteomicsTime-course proteomics analysis of human regulatory T cell (Treg) differentiation
Human naïve CD4+ T cells (CD4+ CD45RA+ CD25- CD45RO- CD8- CD14- CD15- CD16- CD19- CD34- CD36- CD56- CD123- TCRγ/δ- HLA-DR- and CD235a-) were magnetically negatively isolated from peripheral blood. Cells were stimulated with anti-CD3/anti-CD28 antibodies plus IL-2, and samples were taken at 6h, 24h, ...

TranscriptomicsCXCR3+ Treg cells suppress Th1-immune responses through expression of the co-inhibitory receptors CD85k and Lag-3
CD4+Foxp3+ Treg cells are essential for maintaining self-tolerance and preventing excessive immune responses. In the context of Th1 immune responses, co-expression of the Th1 transcription factor T-bet with Foxp3 is essential for Treg cells to control Th1 responses. T-bet-dependent expression of CXC...

TranscriptomicsRegulatory and effector T cells in Lymphocytic choriomeningitis virus WE infection
In this study, we determined the signature of CD4+Foxp3- effector T cells and CD4+Foxp3+ Treg cells in naive animals and following LCMV WE infection. In addition, transcriptional signatures were determined in CXCR3+ CD4+Foxp3+ Treg cells arising in Th1 settings following LCMV infection.

TranscriptomicsRNA-Seq of human regulatory T cells and effector T cells cultured at standard 37C temperature and in mild hypothermia (33C).
Regulatory T cells (Tregs) play crucial role in maintenance of peripheral tolerance. Numerous clinical trials confirmed safety and efficacy of Treg treatment of for deleterious immune responses. However, Tregs lose their characteristic phenotype and suppressive potential during expansion ex vivo. In...

TranscriptomicsPRONOUNCED PHENOTYPE IN ACTIVATED TREG CELLS DURING A CHRONIC HELMINTH INFECTION
Although several markers have been associated with the characterization of regulatory T cells (Treg) and their function, no studies have investigated the dynamics of their phenotype during infection. Since the necessity of Treg to control immunopathology has been demonstrated, we used the chronic he...
