Fig. 8. Time-course transcriptomics data and T cell subtype composition highlight deregulation of IL-17 signaling and related changes in IL-17 producing T cell types in PD.

A Core genes with an increased expression in PD samples indicate deregulation of IL-17 signaling. Corresponding expression data for PD patients (P1, P2, P3, P4, P5) are shown in relative comparison to HCs (C1, C1_2, C2, C3, C4). The data were normalized for each of the represented genes to the median result of HCs at the respective time-point. B, C Time-course mRNA expression data (0, 2, 4, 8, 12, and 24 h) of the transcription factors RORC and BATF are shown for PD patients and HCs. Median results are indicated by bars and total expression ranges by single data points. P-values for the comparison between PD and HC groups are indicated for the individual time-points by asterisks (ns: not significant; *p-value ≤ 0.05; **p-value ≤ 0.01). DG Flow cytometric analysis was done for CD4+ T cells, 6 h after CD4+ T cell activation. D Purity of the isolated CD4+ T cells was confirmed for HC and PD groups. E, F Significant increase of Th17 (IL-17+) and gamma delta (γδTCR+) subtypes were detected amongst the CD4+ T cells of the PD group. G Significant increase of IL-17 producing T cells was detected amongst the γδTCR + CD4+ T cells subpopulation (γδTCR + IL-17+) of the PD group. Median results of HC and PD groups are indicated by horizontal lines and total percentage ranges by individual data points. P-values for the comparison between PD and HC groups are specified.
