The cellular stress response increases measles virus-induced cytopathic effect.
Plaque area is a measure of the degree of cytopathic effect and a predictor of neurovirulence for tissue culture adapted morbilliviruses. In the present work, the cellular stress response was shown to be a determinant of the expression of distinct measles virus large plaque phenotypes in Vero cells. The emergence of these large plaque phenotypes was associated with increased mean viral transcriptional activity and expression of the viral fusion glycoprotein, but not upregulation of the virus receptor CD46.
