HDAC Inhibitors as Epigenetic Regulators

RBC infected with mature schizonts were enriched by using MACS separation columns (Miltenyi, Auburn, CA, USA) as described [29]. To examine whether is associated with T-cell hyporesponsiveness, we stimulated PBMC from Fil+ and Fil- subjects with the antigens described above. their size and complexity; D, Selection of viable cells; E, Selection of CD3+ cells; F, Selection of CD4+ T cells. Expression of intracelular CD39 (G), CTLA-4 (H), OX-40 (I), LAP-TGF- (J), GITR (L), and LAG-3 (M) was evaluated as shown.(DOCX) pntd.0006327.s003.docx (426K) GUID:?946BB3E8-2337-4B88-90EF-A35925BE723D S4 Fig: Gating strategy to define CD4+ T cell subpopulations (co)expressing CD39 and FOXP3 and HLA-DR, CD69, TNFRII, PD-1, and CTLA-4.

We compared the frequencies of CD39+ and CD39- Treg cells (defined as CD4+CD25hiCD127-FoxP3+ T cells) that expressed a range of regulatory and activation markers. Data are shown for 48 Fil+ and 33 Fil- subjects and were compared using the Wilcoxon signed rank test. Only significant values after controlling for any false discovery rate (= 9) are shown.(DOCX) pntd.0006327.s006.docx (295K) GUID:?5E1AAF6D-C07A-4F7E-B492-8722EE5E0C23 S7 Fig: Changes in the proportions of CD4+ T cells producing IFN-, IL-2, TNF-, Th2-type cytokines, and IL-10 in the presence of anti-CD39 antibody are reversed by adding 2mM adenosine. PBMC from microfilaremic (Fil+) and uninfected (Fil-) subjects TSPAN9 were stimulated with enterotoxin B (SEB) in the presence or absence of anti-CD39 antibody, stained for intracellular cytokines, and then incubated with 2mM adenosine. The % of CD4+ T cells generating each cytokine was estimated by circulation cytometry. Data are offered for 11 Fil+ and 5 Fil- subjects and were compared using the Wilcoxon signed rank test. Only significant values after controlling for any false discovery rate (= 5 for each group [Fil+ and Fil-] and each pair of experimental conditions [SEB vs. SEB+anti-CD39, SEB vs. SEB+anti-CD39+adenosine; SEB+anti-CD39 vs. SEB+anti-CD39+adenosine]) are shown.(DOCX) pntd.0006327.s007.docx (204K) GUID:?1C2E485D-BFEC-4329-85BF-16EAAF3C4599 S1 Table: Panel 1: Monoclonal antibodies used to characterize regulatory and activation markers on CD4 + T cells.
