English: PR8 PB1-F2 peptide induces ASC speck formation. NLRP3-deficient macrophages reconstituted with ASC-cerulean (blue) and NLRP3 were cultured in optical culture dishes (Ibidi) and treated with pHrodo-labeled (red) PB1-F2 peptide and visualized in 3D by z-stack collection (6 confocal planes) every 6 mins for 3.5 hours. Rapid phagocytosis of PB1-F2 peptide induces increased fluorescence of labeled peptide due to decreased pH of phagolysosomal compartment. Uptake of PB1-F2 peptide induces oligomerization of ASC in cytosol to form multimeric ASC speck. Movie is a maximum intensity projection of 3D image series from Imaris. Movie is representative of three independent experiments. |
