Fig. 3. Increased naïve CD8+ T cells and reduced IFN-γ-producing CD8+ T cells in the PLN of Tyk2-deficient NOD mice.

Fig. 3

a Cell number (#) or frequency among CD45+ cells (%) of CD8+ T cells in the PLN and pancreas measured by flow cytometry. Pancreas; 6w (Tyk2+/−, n = 6; Tyk2−/−, n = 6), 11w (Tyk2+/−, n = 5; Tyk2−/−, n = 9), 14w (Tyk2+/−, n = 11; Tyk2−/−, n = 15), and normoglycemic 24w (Tyk2−/−, n = 8) female NOD mice. PLN; 6w (Tyk2+/−, n = 9; Tyk2−/−, n = 7), 11w (Tyk2+/−, n = 11; Tyk2−/−, n = 11), 14w (Tyk2+/−, n = 11; Tyk2−/−, n = 11), and normoglycemic 24w (Tyk2−/−, n = 3) female NOD mice. b Frequency of naïve (CD44lo CD62L+), effector memory (CD44hi CD62L-), and central memory (CD44hi CD62L+) CD8+ T cells in the PLN of 6w female mice (Tyk2+/−, n = 6; Tyk2−/−, n = 6). c Frequency of Ki67+ cells among the indicated immune cells in the PLN of 6w female mice (Tyk2+/−, n = 11; Tyk2−/−, n = 10). d (Left) Representative flow cytometry plots of IFN-γ and IL-17-producing CD8+ T cells upon PMA/iono stimulation in the PLN of 6w female mice. (Right) The graphs indicate the frequency of IFN-γ and IL-17-producing CD8+ T cells among CD8+ T cells in the PLN at the indicated ages (6w (Tyk2+/−, n = 9; Tyk2−/−, n = 7), 11w (Tyk2+/−, n = 9; Tyk2−/−, n = 10), and 14w (Tyk2+/−, n = 14; Tyk2−/−, n = 14)). NT not tested. Data represent the mean ± SEM. P-values were calculated using two-tailed Student’s t tests.
