Effects of NEDD4 or MARCH8 silencing on BST2 subcellular localization. siRNA-transfected HeLa cells were permeabilized before fixation and immunostained with antibodies against BST2 (green) and transferrin receptor (TfR, early/recycling endosomes; red) (A) or HRS (endosomes/MVBs; red) (C) along with DAPI (blue) to visualize the nucleus of the cells. Cells were observed with a confocal microscope. Scale bars: 10 µm. (B,D) Colocalization between BST2 and TfR or BST2 and HRS was assessed by calculating the Pearson's correlation coefficient on eight images per condition. Each dot represents the Pearson's correlation coefficient of one image featuring at least three cells. Error bars represent the mean±s.e.m. from each image (n=3), ***P<0.001 (Student's t-test).
