Effect of abrogated DNA-binding of thyroid hormone receptor alpha on the gene expression in CD25- CD4+ naive T cells and CD25+ CD4+ regulatory T cells

ABSTRACT: Thyroid hormones (TH) have emerged as important regulators of the immune system, mediating pro- and anti-inflammatory actions. However, the role of TH in T cells, which are central players of protective immunity has remained largely elusive. To address the impact TH on CD4 T cell immunity, we used RNA-sequencing analysis of naive CD4 T cells and Treg isolated from spleens of mice with a mutation in the DNA binding domain of TRα (TRαGS) or WT littermates. In absence of canonical TRα signaling gene expression profile of naive CD4 T cells was altered with enriched differential expression of genes involved in T cell homeostasis and migration. In TRαGS Treg increased expression of activation and migratory markers was found. Moreover, abrogated canonical TRα signaling was also related to changes in NFκB signaling pathway in Treg, which has been previously related to Treg induction and function. Hence, our findings provide new insight in the effect of canonical TRα singlaing in CD4 T cell immunity.

Gene expression profiles of CD4+CD25+ regulatory T cells during acute and chronic viral infection

Project description:Regulatory T (Treg) cells act as terminators in the case of T cell immunity during the acute phase of viral infection. However, their roles in chronic viral infection are not completely understood. We compared the phenotype and function of Treg cells during acute and chronic viral infection using lymphocytic choriomeningitis virus-infected mouse models. Chronic infection, unlike acute infection, led to induction of Treg cells and upregulation of various inhibitory receptors. Treg cells isolated from chronically infected mice (chronic Treg cells) displayed greater suppressive capacity for inhibiting T cell proliferation and subsequent cytokine production than those from naM-CM-/ve (naive Treg cells) or acutely infected mice (acute Treg cells). These gene expression profiles provided evidence that chronic Treg cells display characteristics distinct from either naive or acute Treg cells. Mouse splenic CD4+CD25+ regulatory T cells were analyzed at 0 day and 16 day after acute or chronic viral infection with LCMV Arm or CL13, respectively.

miRNA expression in CD4+CD25- conventional (Tconv) and CD4+CD25+ regulatory T (Treg) cells

Project description: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, purified from the same pooled mice. One replicate on 1 array.

Project Title: Proteome analysis of CD4+ T cell subsets

Project description:Functionally distinct CD4+ helper T (Th) cell subsets, such as Th1, Th2, Th17, and regulatory T cells (Treg), play a pivotal role in the host-defense against pathogen invasion and the pathogenesis of inflammatory disorders. In this project, DIA-MS-based proteome analysis was performed on naïve CD4+ T, Th0, Th1, Th2, Th17 and iTreg cells using Q Exactive HF-X (Thermo Fisher Scientific) to search for proteins that differ among the cell subsets.

Human Fetal and Adult Peripheral Naïve CD4+ T cells and CD4+CD25+ Treg cells

Project description:We compared differences in fetal and adult T cells by performing whole genome profiling on sort-purified T cells (naïve CD4+ and Treg cells) from human fetal specimens (18-22 gestational weeks) and adult specimens (age 25-40 years old). Fetal and Adult Naïve CD4+ T cells phenotype: CD3+CD4+CD45RA+CCR7+CD27+, Fetal and Adult CD4+CD25+ Treg phenotype: CD3+CD4+CD25bright Four different groups were analyzed: Fetal Naïve CD4+ T cells, Adult Naïve CD4+ T cells, Fetal Treg cells, Adult Treg cells. For each group three independent donors were analyzed.

Systemic inflammation drives rapid conversion of conventional CD4+ T cells to Treg in vivo.

Project description:The immune system faces a task that approximates cognition in its complexity as it processes a multitude of intrinsic and extrinsic signals and integrates these into responses of the appropriate class, specificity, magnitude, and duration for a given threat, with the host’s life often depending on the outcome. CD4+ T lymphocytes occupy a unique role in the generation and regulation of immunity within this context and influence multiple innate and adaptive cell types. With respect to CD8+ cytotoxic T lymphocytes (CTL), CD4+ T cells function early in the response as ‘helpers’ (TH) to increase its magnitude and functionality, and later as regulatory cells (Treg) to restore homeostasis and avoid immune pathology. Using a Listeria monocytogenes (Lm) infection model, we probed whether the conditions of initial pathogen encounter could influence the generation of TH versus Treg. Infection induces rapid polyclonal conversion to functional FoxP3+CD25+ Treg within 24 hours. These findings resolve long-standing questions regarding the requirement for TH and reveal a remarkable degree of plasticity in the function of CD4+ T cells, which can be quickly converted to Treg in vivo in response to acute inflammation.

At low dose infection, CD4+ T cells ‘help’ CTLs via CD40-CD40L signaling, while high dose infection induces rapid polyclonal conversion to functional FoxP3+CD25+ Treg within 24 hours. These findings resolve long-standing questions regarding the requirement for TH and reveal a remarkable degree of plasticity in the function of CD4+ T cells, which can be quickly converted to Treg in vivo in response to acute inflammation.
