Expression of IL-21, IL-6, Bcl-6 and c-Maf mRNA in PBMC from HC, ITP (-) and ITP (+) patients. (A): Levels of the relative expression of IL-21 mRNA in PBMC from HC, ITP (-) and ITP (+) patients; (B) Levels of the relative expression of IL-6 mRNA in PBMC from HC, ITP (-) and ITP (+) patients; (C) Levels of the relative expression of Bcl-6 mRNA in PBMC from HC, ITP (-) and ITP (+) patients; (D) Levels of the relative expression of c-Maf mRNA in PBMC from HC, ITP (-) and ITP (+) patients. Each data point represents an individual subject, and the data of each sample was an average value of three independent experiments with similar results. The horizontal lines show means. *, p<0.05; **, p<0.01; ***, p<0.001; ns, no significant difference.
