PGRN deficiency does not affect the conversion of naïve CD4+CD25- T cells into iTreg mediated by TGF-β.

Abstract

<p>Naïve CD4+ CD25- T cells isolated from both wildtype (WT) and PGRN-deficient mice were stimulated with plate-bound CD3 Ab and solute CD28 Ab and cultured the cells for 3-4 days in the presence or absence of TGF-β, and the expression of GFP was measured by FACS. (A) The GFP levels in CD4+ T cells in the absence of TGF-β. (B) The GFP levels in CD4+ T cells in the presence of 1 ng/ml TGF-β. (C) The GFP levels in CD4+ T cells in the presence of 10 ng/ml TGF-β. All data were repeated three times with similar results.</p
