Th17 and Th17.1 cells in MS. (a) Representative data demonstrating IL-17A+ and IFNγ+ expression (gated on CD4+ memory cells). Numbers represent the percentage of cells within the quadrant, with negative gates set based on unstimulated controls. (b) Data demonstrating CCR6 expression on IL-17+ cells (gated on CD4+ memory cells). The histograms (Figures (c) and (d)) show CCR6 status of IL-17A+ cells and IL-17A+ IFNγ+ cells, respectively. Th17 as a proportion of CD4+ memory cells (e) in MS vs HV, (f) in RRMS vs SPMS and HV, and (g) in relapse vs remission. Th17.1 as a proportion of CD4+ memory cells (h) in MS vs HV, (i) in RRMS vs SPMS and HV, and (j) in relapse vs remission. Bars indicate the median value for each group. HV: healthy volunteers; IL-17A: interleukin 17A; IFNγ: interferon gamma; MS: multiple sclerosis; REL: relapse; REM: remission; RR: relapsing–remitting multiple sclerosis, SP: secondary progressive multiple sclerosis; Th17: T-helper 17 cell. Mann-Whitney test was performed for comparison of cross data between HV and MS; and between REL and REM. Kruskal-Wallis test was performed for the comparison between HV, RR and SP groups. Bars indicate median values (*p < 0.05, **p < 0.01, ***p < 0.001); all other comparisons were nonsignificant (p > 0.05).
