FIG. 7.

CD4⁺ CD25^high T cells express high FoxP3, IL-10, and TGF-β mRNA levels. Real-time PCR for (A) FoxP3 and (B) IL-10 and TGF-β isoforms with RNA isolated from CD4⁺ CD25^high or CD4⁺ CD25⁻ T cells sorted from populations incubated with H. pylori-infected cells and compared to that of naïve T cells from the same donor illustrates that the CD25^high population of T cells produced more RNA for these genes than the CD25⁻ population. The mean (+SEM) increase over naïve T cells is shown for triplicates.
