1 Stimulation of alpha7 nicotinic acetylcholine receptor by nicotine increases suppressive capacity of naturally occurring CD4+CD25+ regulatory T cells in mice in vitro. Nicotine CD4 antigen Mus musculus
2 We found that CD4(+)CD25(+) Tregs from naive C57BL/6J mice positively expressed alpha7 nAChR, and its activation by nicotine enhanced the suppressive capacity of Tregs. Nicotine CD4 antigen Mus musculus
3 In the supernatants of CD4(+)CD25(+) Tregs/CD4(+)CD25(-) T-cell cocultures, we observed a decrease in the concentration of IL-2 in nicotine-stimulated groups, but nicotine stimulation had no effect on the ratio of IL-4/interferon (IFN)-gamma, which partially represented T-cell polarization. Nicotine CD4 antigen Mus musculus
4 In the supernatants of CD4(+)CD25(+) Tregs/CD4(+)CD25(-) T-cell cocultures, we observed a decrease in the concentration of IL-2 in nicotine-stimulated groups, but nicotine stimulation had no effect on the ratio of IL-4/interferon (IFN)-gamma, which partially represented T-cell polarization. Nicotine CD4 antigen Mus musculus
5 In the supernatants of CD4(+)CD25(+) Tregs/CD4(+)CD25(-) T-cell cocultures, we observed a decrease in the concentration of IL-2 in nicotine-stimulated groups, but nicotine stimulation had no effect on the ratio of IL-4/interferon (IFN)-gamma, which partially represented T-cell polarization. Nicotine CD4 antigen Mus musculus
6 In the supernatants of CD4(+)CD25(+) Tregs/CD4(+)CD25(-) T-cell cocultures, we observed a decrease in the concentration of IL-2 in nicotine-stimulated groups, but nicotine stimulation had no effect on the ratio of IL-4/interferon (IFN)-gamma, which partially represented T-cell polarization.
