Figure Lengend Snippet: FACS analysis showed an increase of CD4 +ve CD25 +ve CD127 low/- Treg population after PTP1B and DUSP4 (MKP-2) siRNA-based knockdown in PBMCs of PMOS (n=12) subjects. A: bar graph representation showing the gene expression of PTP1B and DUSP4 across the PTP1B, DUSP4, and both silenced PBMCs. B: Dot plot and histogram representation of gating strategy with P1 shows lymphocyte population, P2 shows CD4-FITC +ve population, P3 shows CD25-PE Cy7 +ve population and P4 shows CD127 low/- Treg population. Gating is based on histogram of unstained and stained population (FITC, PE Cy7 and Alexa Fluor 647 respectively). C: Dot plot representation of CD4-FITC +ve CD25-PECy7 +ve CD127-Alexa Fluor 647 low/- (P4) Treg population of all treatment conditions including; untreated, IL-2 treated, control siRNA silenced, control siRNA silenced with IL-2, PTP1B siRNA silenced without IL-2 and with IL-2, DUSP4 siRNA silenced without IL-2 and with IL-2, and PTP1B+DUSP4 siRNA silenced without IL-2 and with IL-2. D: Dot and truncated violin plot representation of the percentage of CD4 +ve CD25 +ve CD127 low/- Treg population in lymphocyte events across all the treatments. Each dot represents an individual subject. One-way ANOVA was performed using GraphPad Prism 8 and p-value< 0.05 were considered as statistically significant.
Article Snippet: After 24 hours of siRNA treatment, the cells were stimulated with 300IU of recombinant IL-2 (rIL-2) (#130-097-743, Miltenyi Biotech, Germany).
