From: Expression of CD39 on FoxP3+ T regulatory cells correlates with progression of HBV infection
CD39 was expressed variably but preferentially on memory Treg cells. PBMCs from healthy donors were stained with anti-CD4, -CD39, -CD45RA, or -FoxP3 monoclonal antibodies (mAbs) and analyzed by FACS. Dot plots gated on CD4+ T cells are shown from a representative sample. (A) Expression of CD39 in the gated CD4+ T cells of PBMCs. (B) Co-expression of CD39 and FoxP3 in the gated CD4+ T cells of PBMCs. Bar graph for (B) shows the percentage of CD39 expression on FoxP3+CD4+ T cells. (C) Co-expression of CD39 and CD45RA in the gated CD4+ T cells of PBMCs. The bar graph for (C) shows the percentage of CD39 expression on CD45RA-CD4+ T cells. *** P < 0.001.
