Sodium vanadate enhanced Newcastle disease virus (NDV)‐induced cell fusion in L cells, and there was a direct correlation between the degree of cell fusion and the dose of vanadate added. When anti‐F protein of NDV monospecific antiserum was added to the culture fluid of L cells infected with NDV, the enhancement of cell fusion was suppressed. In contrast, neither anti‐HN nor anti‐M protein monospecific antiserum inhibited the enhancement. Incubation at low temperature (4 C) and addition of sodium azide to the culture fluid suppressed the enhancement. The suppression by azide was seen only when the drug was added within 5 min after the beginning of incubation of NDV‐infected L cells with vanadate. On the other hand, incubation at low temperature inhibited the enhancement at any time during incubation with vanadate. Cytochalasin D also inhibited the enhancement if it was added at any time during incubation with vanadate.
