Impact of Vesicular Stomatitis Virus M Proteins on Different Cellular Functions
Fig 5
Subcellular localization of VSV M proteins.
BHK-T7 cells were transfected for 2 h with pTM1 encoding VSV M1 (A-D), M2 (E-F) or M3 (G-H), and fixed 6 h later. Expression and localization of viral proteins were analyzed by immunofluorescence using specific monoclonal antibodies against M1 that also recognize M2 and M3, and the corresponding mouse secondary antibody conjugated to Alexa 488. Localization of M1 in intracellular membranes and dot-like structures at the nuclear envelope or at the cell surface is shown in panels A, B and C, respectively. Localization of M2 and M3 in intracellular compartments (E and G) or surrounding the nucleus (F and H) is shown. Images were acquired with an Axiovert microscope connected to a digital camera.
