title: Sequential onset of permeability changes in mouse ascites cells induced by Sendai virus.
abstract: The addition of haemolytic Sendai virus to cells induces membrane changes in the following sequence: (i) Increased permeability to ions, (ii) increased permeability to low molecular weight metabolites, (iii) increased permeability to proteins. The consequences of an increased permeability to ions are: (a) alteration of membrane potential, (b) net changes in intracellular cations and (c) cell swelling, in that order. Depending on virus: cell ratio, Ca2+ concentration and temperature, it is possible to observe ion leakage without metabolite or protein leakage, and ion and metabolite leakage without protein leakage. A model for the induction of permeability changes is presented.
