Supplementary MaterialsS1 Fig: All medical groups have similar viability post activation. = 6 (B) IGRA-ve; N = 4 (A) and N = 7 (B) IGRA+ve and N = 5 ATT (B) donors. P value was determined by non-parametric One-Way ANOVA KruskalCWallis test with Dunns multiple comparisons test. **p 0.01, *p 0.05.(PDF) ppat.1007289.s002.pdf (60K) GUID:?C2CB2EFA-8E7D-456B-81FA-F610094C14C8 S3 Fig: Treg mediated suppression is lower in PTB CD4+ Teff cells activated with an antigen specific stimulus. Treg and PBMC minus Treg fractions were sorted with the help of circulation cytometry. The PBMC minus Treg portion was cultured only (1:0) or along with autologous Treg at a 1:1 percentage. Cells were triggered with 10 g/ml lysate and IFN secretion was measured after 4 days by ELISA (A). Based upon levels of IFN in absence and presence of Treg cells, percent suppression was determined (B). Data demonstrated is median rate of recurrence/range from 10 PTB donors and 4 IGRA-ve donors. value between paired samples was determined by Wilcoxon matched-pairs authorized rank test and between unpaired by Mann Whitney test.(PDF) ppat.1007289.s003.pdf (59K) GUID:?EAF861CE-DC67-41D8-B48A-E2E66E3FBE63 S4 Fig: Expression of CD38 and PD-1 does not vary about Teff cells from different medical categories. Thawed PBMC were stained with Avid, anti-CD3, anti-CD4, anti-CD45RA, anti-CD127, anti-CD25 anti-CD38 and anti-PD-1. Stained samples were acquired on a FACS Aria Fusion after using appropriate single color payment settings. A sequential gating strategy was employed to arrive at live CD3+CD4+CD45RA-CD127hiCD25lo Teff cells. Representative FACS plots of CD38+ (A) and PD-1+ (C) Teff cells from all medical groups are demonstrated. Teff frequencies of CD38+ (B) and PD-1+ (D) were determined and plotted. Data demonstrated is median rate of recurrence with range from multiple donors (IGRA-ve N = 9, IGRA+ve N = 11, PTB N = 27, ATT 6 months N = 8) in each medical category. P value was determined by non-parametric One-Way ANOVA KruskalCWallis test.(PDF) ppat.1007289.s004.pdf (233K) GUID:?37E7A31D-EF08-48FC-809F-9CBCDFA585E7 S5 Fig: Expression of HLA-DR, CD38 and PD-1 does not consistently vary about Treg cells from different medical categories. Thawed PBMC were Rabbit Polyclonal to TAS2R1 stained with Avid, anti-CD3, anti-CD4, anti-CD45RA, anti-CD127, anti-CD25, anti-HLA-DR, anti-CD38 and anti-PD-1. Stained samples were acquired on a FACS Aria Fusion after using appropriate single color payment settings. A sequential gating strategy was employed to arrive at live CD3+CD4+CD45RA-CD127loCD25hi Treg cells. Frequencies of HLA-DR+ (A), CD38+ (B) and PD-1+(C) Treg cells were determined and plotted. Data demonstrated is median rate of recurrence with range from multiple donors (IGRA-ve N = 9, IGRA+ve N = 11, PTB N = 27, ATT 6 months N = 8) in each medical category. P value was determined by non-parametric One-Way ANOVA KruskalCWallis test with Dunns multiple comparisons test. *p 0.05.(PDF) ppat.1007289.s005.pdf (83K) GUID:?B5DD50B0-F249-4403-8253-D4B66326CD0E S6 Fig: HLA-DR+ Teff cells from PTB subject matter are resistant to Treg mediated suppression. Sorted PTB total, HLA-DR- and HLA-DR+ Teff cells were co-cultured with autologous Treg cells at a percentage of 1 1:1. Cells were triggered with anti-CD3/anti-CD28 beads at beads: Teff cell percentage of 1 1:1. After 4 days, Hyodeoxycholic acid culture supernatants were collected and IFN was measured by ELISA. Percentage suppression was determined based on IFN secretion in control cultures without Tregs and in cultures with Treg cells. Data demonstrated is median rate of recurrence/range N = 4 for each cellular subset. P value was determined by non-parametric One-Way ANOVA KruskalCWallis test with Dunns multiple comparisons test. * p 0.05.(PDF) ppat.1007289.s006.pdf (25K) GUID:?6ADC7A30-3D2B-409A-B356-90F71FFDEF58 S7 Fig: Treg mediated suppression of specific responses is restored post depletion of HLA-DR+CD4+ T cells in PTB. Treg and PBMC minus Treg (denoted as Hyodeoxycholic acid total Teff) fractions were sorted with the help of circulation cytometry from PTB donors. An additional subset of PBMCs depleted of Tregs and HLA-DR+CD4+ Teff (denoted as HLA-DR- Teff) was also sorted from your same PTB donors. Total and HLA-DR- Teff PBMC fractions were cultured Hyodeoxycholic acid only (1:0) or along with autologous Treg at a 1:1 percentage. Cells were triggered with 10 g/ml lysate and IFN secretion was measured after 4 days by ELISA (A). Based upon levels of IFN in absence and presence of Treg cells, percent suppression was determined (B). Data demonstrated is median rate of recurrence/range from 6 donors each from PTB. value between paired samples was determined by Wilcoxon matched-pairs authorized rank test. *p 0.05.(PDF) ppat.1007289.s007.pdf.
