Patterns of Cytopathology and Lysosomal Enzyme Release in Poliovirus-infected HEp-2 Cells Treated With Either 2-(α-Hydroxybenzyl)-Benzimidazole or Guanidine HCl Guskey, L. E. and Smith, P. C. and Wolff, D. A.,, 6, 151-161 (1970), doi = https://doi.org/10.1099/0022-1317-6-1-151, publicationName = Microbiology Society, issn = 0022-1317, abstract= SUMMARY The viral inhibitors guanidine hydrochloride and 2-(α-hydroxybenzyl)- benzimidazole (HBB) were used to study the relationship between lysosomal enzyme release and the development of poliovirus-induced cytopathic effect (CPE) in HEp-2 cells. Lysosomal enzyme release, the development of CPE and virus replication were inhibited or delayed if these antiviral agents were added up to 2 to 3 hr after infection. When added later the agents were no longer effective. It is suggested that a virus-induced protein produced during 3 hr after infection is responsible for lysosomal enzyme release., language=, type=
