WebLike vacuoles formed during SV40 infection, HRas-induced vacuole formation in glioblastoma cells was independent of ERK signaling and blocked by chemical inhibition of Rac1 . Furthermore, in both ras-activated glioblastoma cells and SV40-infected cells, vacuoles contain endosomal markers such as Lamp-1 and undergo extracellular fluid … Total destruction of the host cell monolayer is the most severe type of CPE. To observe this process, cells are seeded on a glass surface and a confluent monolayer of host cell is formed. Then, the viral infection is introduced. All cells in the monolayer shrink rapidly, become dense in a process known as pyknosis, and detach from the glass within three days. This form of CPE is typically seen with enteroviruses.

Webthe thusly modified endosomes/lysosomes are termed cytopathic vacuoles or CPVs. In the first study, a RUBV expressing a FLAG epitope-tagged P150 was used to co-immunoprecipitate putative interacting cell proteins from an infected cell lysate fraction enriched for CPVs using differential centrifugation. WebVirus accumulates within the inclusions but nucleocapsids do not. ‘Type-1 cytopathic vacuoles’ (Grimley, Berezesky & Friedman, 1968) are not found. Between 40 and 60 h after infection, the cell-associated virus titre falls by 1 log unit. Cytoplasmic inclusions lose electron-dense material and are transformed into microvesiculated vacuoles.
