The kinetics of the fusion process between erythrocyte ghosts, as induced by Sendal virus, were readily revealed by a simple fluorescence procedure previously employed to characterize the fusion of viruses with biological membranes. The method relies on the relief of fluorescence selfquenching of the membrane-inserted probe octadecyl Rhodamine B chloride (R18) as occurs when labeled membranes fuse with unlabeled counterparts. The kinetics of R18 insertion into ghost membranes, the non-exchangeable properties of the fluorophore and the kinetics, and some characteristics of Sendai virus-induced fusion of ghosts, are described. We propose that the experimental approach may be particularly advantageous to obtain insight into the efficiency and mechanism of a wide range of fusogens, capable of inducing fusion of erythrocyte membranes.

The membrane fusion and cell swelling stages of Sendai virus-mediated cell-cell fusion have been studied by thin-section and freeze-fracture electron microscopy. Sites of membrane fusion have been detected in human erythrocytes arrested at the membrane fusion stage of cell fusion and in virtually all cases a fused viral envelope or envelope components has been identified thus providing further direct evidence that cell-viral envelope-cell bridge formation is the membrane fusion event in Sendai virus-induced cell fusion. Radial expansion of a single virus bridge connecting 2 cells is sufficient to produce a fused cell. Membrane redistribution which occurs during this cell swelling stage of the fusion process is often accompanied by the formation of a system of membrane tubules in the plane of expansion of the virus bridge. The tubules originate from points of fusion between the bridging virus envelope and the erythrocyte membrane and also expand radially as cells swell. Ultimately membrane rupture occurs and the tubules appear to break down as small vesicles. When previously observed in cross-sectioned cells these membrane tubules were interpreted as sites of direct membrane fusion. The present study indicates that this interpretation is incorrect and shows that the tubules are generated subsequent to membrane fusion when 2 cells connected by a virus bridge are induced to swell. A mechanism to explain the formation of this system of membrane tubules is proposed.
