PGRN-deficient CD4+CD25+ Treg decreased the suppressive capacity to Teff proliferation.

Abstract

<p>Freshly isolated, CFSE-labeled CD4+CD25- T cells from Thy1.1 mice were used as Teff and co-cultured with Tregs at ratios of 1∶2, 1∶1, 2∶1, 4∶1 and 8∶1. CFSE-based Teff proliferation suppression assay in vitro in which 5×10<sup>5</sup> CFSE-labeled Teff cells were stimulated with CD3 antibody in the presence of mitomycin-treated APC cells and different ratios of FACS sorted wild type or PGRN-deficient Tregs. The CFSE proliferation was evaluated by FACS. All data are representative of three separate experiments. (A) Negative control. (B) Positive control. (C) The CFSE dilution when Teff co-cultured with Tregs at ratios of 1∶2. (D) The CFSE dilution when Teff co-cultured with Tregs at ratios of 1∶1. (E) The CFSE dilution when Teff co-cultured with Tregs at ratios of 2∶1. (F) The CFSE dilution when Teff co-cultured with Tregs at ratios of 4∶1. (G) The CFSE dilution when Teff co-cultured with Tregs at ratios of 8∶1. Data represent as a means ±SE of a representative experiment. *<i>p</i><0.05; **<i>p</i><0.01.</p
