title: Similarities between cytomegalovirus-induced cell rounding and contraction of smooth muscle cells.
abstract: Cytomegalovirus infection of human fibroblastic cell cultures resulted in rounding of the cells and a subsequent decrease in their size. Smooth muscle relaxing agents such as papaverine, hydralazine, diazoxide, nitroprusside and verapamil blocked these early cytopathogenic effects suggesting that cell rounding results from a contractile-like response involving an influx of calcium ions.
