Figure Lengend Snippet: Figure 3. ISKNV infection induces ferroptosis in CPB cells. (A) Transmission electron microscopy of CPB cells treated with DMSO (72 h), erastin (10 µmol/L, 72 h), and ISKNV (100 MOI, 24 h, 48 h, 72 h). Scale bars = 1 µm. (B) Analysis of Fe2+ levels in CPB cells after treatment with ISKNV (100 MOI) using the fluorescent probe FerroOrange by laser scanning confocal microscopy. Scale bars = 20 µm. (C) Quantitative analysis of the mean fluorescence intensity of (B) using Image J. (D) Analysis of intracellular ROS levels using DCFH-DA staining, and laser scanning confocal microscopy of CPB cells treated with ISKNV (100 MOI) for 24–72 h. Scale bars = 10 µm. (E) Quantitative analysis of the mean fluorescence intensity of (D) using Image J. (F–H) Detection of Fe2+, ROS, and MDA levels in cell lysates treated with ISKNV (100 MOI) for 24–72 h by microplate reader. * p < 0.05, ** p < 0.01, and *** p < 0.001, with p > 0.05 considered not significant (ns).

Article Snippet: The Fe2+ content of the cells was detected by laser scanning confocal microscopy and a microplate reader using the fluorescent probe FerroOrange (Elabscience, E-BC-F101, Wuhan, China).
