Differential Incorporation of Cholesterol by Sindbis Virus Grown in Mammalian or Insect Cells

Abstract excerpt

Cholesterol has been shown to be essential for the fusion of alphaviruses with artificial membranes (liposomes). Cholesterol has also been implicated as playing an essential and critical role in the processes of entry and egress of alphaviruses in living cells. Paradoxically, insects, the alternate host for alphaviruses, are cholesterol auxotrophs and contain very low levels of this sterol. To further evaluate...
