NF-κB is highly activated in epithelial cells in vivo in high-level infection. (A?E) Cohorts of twenty NFκB:EGFP fish were infected by immersion with C. albicans CAF2-dTomato and imaged by confocal microscopy at 5 dpi. (A?C) In vivo expression of GFP in high-level-infected (A) and uninfected (B) swimbladder; yellow arrows indicate the epithelial layer. (C) Magnification of image A (white box), with C. albicans inside a phagocyte (white arrows). (D,E) Ex vivo dissected swimbladder expression of EGFP from high-level infected zebrafish (D) with highlighted epithelial (green arrow towards green box) and mesothelial (black arrow towards gray box) layers and uninfected swimbladder (E). Scale bars: 100 μm (A,B,D,E) and 20 μm (C). Maximum projections of n slices: n=8 for A and B, n=1 for C?E. Images are representative of four independent experiments.
