title: Ca2+-sensitive permeability changes caused by influenza virus.
abstract: Influenza virus added to Lettré cells at pH 5.3 induces a permeability change similar to that elicited by Sendai virus at pH 7.4: K+ and Na+ equilibrate across the plasma membrane and low-molecular-weight phosphorylated compounds leak out of cells, which remain impermeable to trypan blue.
