Effects of cytochalasin B on actin and myosin association with particle binding sites in mouse macrophages: implications with regard to the mechanism of action of the cytochalasins

The intracellular distribution of F-actin and myosin has been examined in mouse peritoneal macrophages by immunofluorescence microscopy. In resting, adherent cells, F-actin was distributed in a fine networklike pattern throughout the cytoplasm. Myosin, in contrast, was distributed in a punctate patt...
