Figure Legend Snippet: Increased IL-26 levels in the serum of psoriatic arthritis (PsA) and rheumatoid arthritis (RA) patients. IL-26 serum levels were quantified by ELISA in 35 HCs (white), 29 axial spondyloarthritis (axSpA) (black), 20 PsA (red) and 15 RA (blue) patients. Preincubation with heat-aggregated bovine IgG and signal amplification with biotinyl-tyramide were applied in order to minimize false results through interfering antibodies . Statistical analysis: mean ± SEM, ** p < 0.01, *** p < 0.001 (one-way ANOVA followed by Dunnett post-test for multiple comparisons).
Techniques Used: Enzyme-linked Immunosorbent Assay, Amplification
Figure Legend Snippet: IL26 -expressing cells are only slightly increased in circulating CD4 + and CD8 + T cells from patients with axSpA and PsA. (A) Representative flow cytometry plots of total IL26 + CD4 + T cells with the PrimeFlow assay in a PsA patient. RPLA13A represents the positive control for the assay. (B) Percentages of total IL26 + CD4 + T cells (left) and percentages of IL26 + cells of CD26 + CD161 + CD4 + T cells (right) for HCs ( n = 15; white) and axSpA ( n = 15; black) and PsA ( n = 14; red) patients gated from PBMCs stimulated in vitro with PMA and ionomycin in the PrimeFlow assay. (C) Representative flow cytometry plots of total IL-1R1 + Th17 cells in a PsA patient comparing IL-2 stimulation to unstimulated conditions. (D) Percentages of IL-1R1 + Th17 cells (Th17 cells gated as CD4 + CD45RO + CD161 + CCR6 + CCR4 + CXCR3 − ) of CD4 + cells from HCs ( n = 21; white) and axSpA ( n = 22; black), PsA ( n = 14; red), and RA ( n = 13; blue) patients after in vitro stimulation with IL-2 (1,000 IU/ml) overnight (left) and percentages of IL-1R1 + CD26 + CD161 + cells of CD4 + cells (right). (E) Percentages of total IL26 + CD8 + T cells (left) and percentages of IL26 + cells of CD26 + CD161 + CD8 + T cells (right) for HCs ( n = 15; white) and axSpA ( n = 15; black) and PsA ( n = 14; red) patients gated from PBMCs stimulated in vitro with PMA and ionomycin. Statistical analysis: mean ± SEM, * p < 0.05, ** p < 0.01 (one-way ANOVA followed by Dunnett post-test for multiple comparisons).
Techniques Used: Expressing, Flow Cytometry, Positive Control, In Vitro
Figure Legend Snippet: CD4 + T cells from axSpA patients are prone to IL26 expression under typical Th17-favoring conditions in vitro . (A) Total CD4 + T cells from HCs ( n = 20; white) and axSpA ( n = 19; black), PsA ( n = 18; red), and RA n = 13; blue) patients were incubated with different Th17-favoring cytokine combinations in vitro for 6 days, and the expression of IL26 and IL17A was analyzed by qPCR in triplicates. Expression was normalized to two control genes ( ACT and RPL13A ) and is shown as fold expression in relation to basal stimulation with IL-2 only. (B) CD4 + T cells from the same cohort as in (A) were stimulated with IL-2, IL-1β, and IL-23 for 6 days in vitro , and fold expression (triplicates each) of the respective genes is shown in relation to HCs after normalizations for ACT and RLP13A . Statistical analysis: mean ± SEM, * p < 0.05, ** p < 0.01, *** p < 0.001 [ (A) repeated-measures ANOVA and (B) one-way ANOVA followed by Dunnett post-test for multiple comparisons].
