The role of myosin 1 and 6 during the internalisation of viral antigens. (A) Confocal images of the internalisation process at different times post antibody addition, in which the antigen-antibody complexes was visualised with FITC (green signal). Myosins were visualised in red with Texas Red (Myo1) or Alexa Fluor 594 (myo6). (B + C) The effect of ML-7 on the recruitment of myosin 1 (B) or myosin 6 (C) in the internalisation of antigen-antibody complexes. Cells were pretreated with ML-7 for 30 min. Cells were fixed before or 30 min after antibody addition. Antigen-antibody complexes were visualised in green and myosin in red. Arrowheads indicate colocalisation of myosins with antigen-antibody complexes. All images show a single optical section through the cell. Scale bars represent 5 μm.
