Representative images of IL-17Aþ MCs (tryptaseþ cells) in synovia from an OA patient (A) and an RA patient (B). Immunochemical staining of synovia with anti-tryptase mAb (green, a) and anti-IL-17A (red, b) Ab, and a merged image (yellow, c). The cells were stained with DAPI (blue). The white arrow heads indicate tryptase-IL-17A double-positive cells. Bar ¼ 10 mm. (C) As negative controls, a synovium sample from an OA patient was stained with mouse IgG1 and goat IgG. The results are representative of separate analyses using 6 patients with OA and 6 patients with RA.

doi: 10.3390/biomedicines9091095

Figure Lengend Snippet: Histologic examination of the lung tissue from SKG mice at 20 weeks after a curdlan injection with/without PLAG treatment. ( A ) Hematoxylin and eosin (upper panels) and Masson’s trichrome (lower panels) staining of the lung tissues. Severe lung inflammations were observed in the curdlan-induced SKG mice and these features were attenuated in the PLAG-treated curdlan-induced SKG mice. ( B ) Opal multiplexed immunofluorescent images and semi-quantitation of the total, GM-CSF + and IL-17A + neutrophil accumulation in the lung tissues. The GM-CSF + neutrophil accumulation was significantly decreased in the PLAG-treated curdlan-induced SKG mice compared with those without PLAG treatment whereas the IL-17A + neutrophil accumulation was not attenuated. The values represent the mean of three independent experiments ± SEM. * p < 0.05. PLAG: acetylated diacylglycerol 1-palmitoyl-2-linoleoyl-3-acetyl-rac-glycerol.

Figure Lengend Snippet: Construction of recombinant cytokine OMVs and their pattern diagram for immunization as adjuvant (A). HEK-293T and GES-1 cells were divided into three groups each: 100 μg of OMVs delivering cytokine IFN-γ (EGFP) was added to the first group, 100 μg of OMVs delivering cytokine IL-17A (mCherry) was added to the second, and 50 μg each of OMVs delivering cytokine IFN-γ (EGFP) or IL-17A (mCherry) was added to the third, followed by incubation in a cell culture incubator. Eukaryotic expression plasmids are highly expressed in both HEK-293T and GES-1 cells as observed by laser confocal microscopy (B).

doi: 10.1101/2023.06.26.546595

Figure Lengend Snippet: MLN cells and splenocytes of mice were isolated after 8 weeks of immunization, and the expression levels of cytokines IL-17 and IFN-γ in different groups were assessed by quantitative ELISA after immunization with UreB (A, C) or WCV (B, D) as vaccine antigens combined with recombinant OMVs or CT as adjuvants. Each group comprised nine mice, and data are expressed as mean ± SD per group. The least significant difference test was performed to determine whether the distinctions between the means of the groups were significant. P < 0.05 and P < 0.01 represent the differences between the related groups.
