Mouse splenic CD4 + T cell were isolated from spleen by using
mouse anti-CD4 microbeads (Miltenyi Biotec, Germany). To isolate Treg cells, CD4 + T-cells were cultured with plate-bound
anti-mouse CD3 (1 μg/mL; BD Biosciences),
soluble anti-mous CD28 (1 μg/mL; BD Biosciences),
anti-IFN-γ (2 μg/ml),
anti-IL-4 (2 μg/ml),
human recombinant transforming growth factor-β (TGF-β; 5 ng/mL; PeproTech, London, UK), and
Retinal (0.1 μM; Sigma-Aldrich, St. Louis, MO)(16).
Human CD4 + T cells were isolated from PBMC by using
human anti-CD4 microbeads (Miltenyi Biotec, Germany). To isolate human Treg cells, human CD4 + T-cells were cultured with plate-bound anti-human CD3 (1 μg/mL), soluble anti-human CD28 (1 μg/mL),
anti-IFN-γ (2 μg/ml),
anti-IL-4 (2 μg/ml), human recombinant TGF-β (5 ng/mL) and
Retinal (0.1 μM).
After three days, the induced Treg cells were stained with CD4, CD25 and then sorted using a MoFlo cell sorter to obtain a ~ 95% pure CD4 + CD25 + population.
