Previous data have suggested that B-cell–depletion therapy may induce the settlement of autoreactive long-lived plasma cells (LLPCs) in the spleen of patients with autoimmune cytopenia. To investigate this process, we used the AID-CreERT2-EYFP mouse model to follow PCs engaged in an immune response....
Naturally occurring FoxP3+CD4+CD25+high regulatory T cells (Tregs) play an important role in dominant tolerance, suppressing auto-reactive CD4+CD25- T cell activity. Although Tregs from T1D subjects are functionally deficient, there is little knowledge of the molecular mechanisms that orchestrate th...
This study evaluated changes in gene expression upon IL-7 treatment in human naive and memory Treg. CD4+CD25+CD127low naïve and memory Treg were isolated from fresh PBMC and separately stimulated with ?CD3?/CD28 coupled beads (Invitrogen-Dynal) at a 1:10 bead/T cell ratio, treated with or without 10...
In this study we determined whole genome gene expression of murine naive CD4+ T cells, in vitro differentiated Th17 cells, and CD4+ T cells isolated from experimental autoimmune encephalitomyelitis (EAE)-affected animals either after adoptive transfer of Th17 cells or after immunization with MOG35-5...
Autoimmune diseases are often associated with HLA molecules. Multiple sclerosis (MS) is a prototypical example with the HLA-DR15 haplotype as strongest genetic factor. How it contributes to MS is not clear, but key to understand this and other autoimmune diseases. Autoreactive CD4+ T cells and proin...
Experimental autoimmune encephalomyelitis (EAE) is a murine model of multiple sclerosis, a chronic neurodegenerative and inflammatory autoimmune condition of the central nervous system (CNS). Pathology is driven by the infiltration of autoreactive CD4+ lymphocytes into the CNS where they attack neur...
After positive selection in the thymus, the newly generated single positive (SP) thymocytes are phenotypically and functionally immature and undergo apoptosis upon antigen stimulation. In the thymic medullary microenvironment, SP cells progressively acquire immunocompetence. Negative selection to r...
CNS autoimmunity is induced by autoreactive T cells reactive against CNS antigen. However how these T cells become able to transgress the blood brain barrier is not CNS autoimmunity is induced by autoreactive T cells reactive against CNS antigen. Here a gene expression profile of the pathogenic T ...
For metabolic profiling of human CD4+ T cells，stable isotope labeling (SIL) and metabolomics SIL experiments were performed with in vitro-activated T cells using liquid chromatography (LC) coupled to mass spectrometry (MS).
