doi: 10.4049/immunohorizons.1700047

Figure Lengend Snippet: PBMCs from subjects before and after Depo-Provera injection were isolated and the percentage and MFI of integrin α4β7 (A), HIV co-receptor CCR5 (B), and activation marker CD38 (C) were analyzed within the CD3+CD4+ T cell population by flow cytometry. Wilcoxon matched-pairs signed rank test was used to compare values from before Depo-Provera (visit 1), one month after Depo-Provera (visit 2), and 3 months after Depo-Provera (visit 3). Each dot represents one donor. Bars represent median and interquartile range. p≤0.05 was considered significant, p>0.05 was not significant (ns).

Figure Lengend Snippet: The percentage and MFI of cell surface markers integrin α4β7, CCR5, and CD38 on CD3+CD4+ T cells from freshly isolated PBMCS was analyzed within patients who identified as either black (A) or Hispanic (B) by flow cytometry. Each dot represents one donor. Bars represent median and interquartile range. Wilcoxon matched-pairs signed rank test was used for analysis. p≤0.05 was considered significant, p>0.05 was not significant (ns).

Figure Lengend Snippet: PBMCs exposed to HIV-1BaL (MOI 0.01) were cultured for 10 days. In HIV infected PBMCs, cell surface marker expression of integrin α4β7, CCR5, and CD38 cell surface marker expression (A–C) and T cell subsets (D) were measured on HIV p24−CD4+ T cells and HIV p24+CD4+ T cells. Uninfected cells were included as a comparison. Each dot represents one donor. Bars represent median and interquartile range. The Mann-Whitney test was used to compare cell surface marker expression between uninfected, HIV p24− or HIV p24+CD4+ T cells. p≤0.05 was considered significant, p>0.05 was not significant (ns).

Figure Lengend Snippet: Changes in integrin α4β7, CCR5, and CD38 cell surface marker expression (A–C) and CD4+ T cell subsets (D) between study visits were analyzed on HIV p24+CD4+ T cells by FACS analysis. Each dot represents one donor. Bars represent median and interquartile range. Wilcoxon matched-pairs signed rank test was used to compare differences between study visits. p≤0.05 was considered significant, p>0.05 was not significant (ns).

Article Title: Blockade of NF-κB Translocation and of RANKL/RANK Interaction Decreases the Frequency of Th2 and Th17 Cells Capable of IL-4 and IL-17 Production, Respectively, in a Mouse Model of Allergic Asthma

doi: 10.3390/molecules26113117

Figure Lengend Snippet: Effect of inhibitors of IKK (BMS-345541 (BMS)), NF-κB translocation (dehydroxymethylepoxyquinomicin (DHMEQ)) and RANK/RANK-L interaction (osteoprotegerin (OPG)), and glucocorticosteroid (methylprednisolone (MP)) administration on the number of IL-4- and IL-17-producing CD8 + T cells. The relative count ( A , D ) is expressed as a percentage of IL-4- or IL-17-producing cells within CD8 + T cells. The absolute count ( B , E ) represents the number of IL-4- or IL-17-producing CD8 + T cells per lung sample collected from individual mice. * p < 0.05, ** p < 0.01, *** p < 0.001. Examples of dot plot cytograms showing the distribution of IL-4- or IL-17-producing and non-producing cells within CD8 + T cells ( C and F , respectively).

Article Snippet: Subsequently, the cells were stained for surface antigens with fluorochrome-conjugated monoclonal antibodies (mAbs): PerCP-Cy 5.5 rat anti-mouse CD4 (clone RM4-5, IgG2a, κ), APC-Cy7 rat anti-mouse CD8a (clone 53-6.7, IgG2a, κ) and PE-Cy7 rat anti-mouse CD25 (clone PC61, IgG1, λ; all from BD Biosciences).

Figure Lengend Snippet: Gating strategy for flow cytometric data analysis and calculation of the absolute cell counts of lymphocyte subsets. Lymphocytes were identified based on forward and side scatter (FSC/SSC) properties, and then gated for expression of CD4 or CD8 surface receptors. CD4 + T cells were analyzed for expression/co-expression of CD25 and Foxp3. On this basis, Treg (Foxp3 + CD25 + CD4 + ) and non-Treg (the remaining CD4 + T cells, i.e., non-Foxp3 + CD25 + CD4 + T cells) cells were distinguished. Subsequently, IL-4-, IL-10-, IL-17- and TGF-β-producing cells were identified within particular cell subsets. Absolute cell counts of lymphocyte subsets (i.e., number of cells from particular subpopulations per mediastinal lymph node or lung sample) were calculated using the dual platform method, as shown above.
