Cytopathic vacuoles
WebNov 10, 2014 · These spherules are then rapidly endocytosed and ultimately accumulate in the classic cytopathic vacuoles (CPVs) seen in cells containing SFV replicons . In the case of SFV replicons that encode VSV G, endocytosis of the spherules may be inhibited by VSV G (22, 23), resulting in trapping of spherules on the cell surface (Fig. 6B). These ... 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.
