Human CD4+CD25+CD127loFOXP3+Treg Activation by IL-4 and Alloantigen Induces Activated Treg that do not Express CD45RA and Express the IL-5 Receptor Alpha (CD125)Effector T cells have functional subpopulations with distinct cytokine, cytokine receptor, chemokine receptor and transcript...

RESULTS. No differences in Treg populations or CD4+ T-cell naivety (CD45RA+) were found between genotype groups at steady-state. In nave CD4+ T-cells, following 48-hour stimulation, significantly fewer CD25+ T-cells were observed in the minor allele group, with a similar trend observed ...
Treg,其细胞膜表面高表达CD25,并在其胞内特 异性高表达叉头/翼状螺旋转录因子(forhead/ wingedhelixtranscriptionfactor,Foxp3) [2] 。因 此,目前将CD4 + CD25 hi 、CD4 + CD25 + Foxp3 + 作 为鉴别Treg的标记。最近这个研究小组又发现 Treg因其表型和功能的不同又可分成三个不同亚 群即CD45RA + Foxp3...
This response to IL-2 was not restricted to the IL-6Rhi Treg compartment (Fig. 1C), and was consistent with the expansion of total CD4+ CD127lowCD25+ Tregs reported previously [15]. The IL-2-induced increase in IL-6Rhi Treg frequency was sustained for up to three days after ...
Population IV includes activated effector CD4+T cells that do not express CD45RA, CD25 or Foxp3. Population V identifies C D4+ cells with high CD45RA expression and no CD25 and Foxp3. Activation of CD4+ T cells would expand Population IV while activation of Treg would increase...
CD4+T cells can be divided into five populations using CD45RA and either Foxp3 or CD25 expression37,43(Fig.1A). Population I mainly contains thymus derived resting Treg that express CD45RA, CD25 and Foxp3 and is large at birth but decreases with age42. Population II identifies activated ...
Autoantibodies induce various autoimmune diseases, including systemic lupus erythematosus (SLE). We previously described that CD4+CD25−LAG3+ regulatory T cells (LAG3+ Treg) are regulated by Egr2, a zinc-finger transcription factor required for the ind
In some cases (C), the box and whiskers are all at 0 and not represented on the graph. Available samples from arm A (n = 18) and arm C (n = 40) were tested for Treg (CD4+CD127-CD25+FOXP3+) (Figure 3D) and central memory (CD4+CD45RA-CCR7+) phenotype (Figure...
Gating strategy and definition of cell populations Cells were gated for lymphocytes on the basis of for- ward and side scatter profiles and further gated for CD4 expression. By using the cell surface markers CD25 and CD127, the Treg population was identified as CD4+ CD25+/highCD127−/low ...
