Figure 4. NET release from synovial cells and peripheral PMNs from patients with gout.
A) NET formation by synovial cells, peripheral PMNs from patients with gout and from control PMNs treated with synovial fluid or serum from patients with gout, as assessed by immunofluorescense microscopy after co-staining with DAPI (blue) and MPO (green). Inhibitory effect of treatment with 3-MA on the release of NETs from synovial cells. Scale bars, 30 µm. Original magnification 400x. One out of six independent experiments is shown. B) The effect of treatment with 3-MA or bafilomycin A in the percentage of NET releasing cells presented in panel A. Data are representative of six independent experiments and presented as mean ± SD. ‡ P<0.05 compared to control, * P<0.05.
