  • Title: Influence of cellular functions on the evolution of persistent infections with Junin virus.
    Author: Candurra NA, Damonte EB.
    Journal: Arch Virol; 1985; 86(3-4):275-82. PubMed ID: 2998303.
    Abstract:
    Vero cell cultures persistently infected with Junin virus and subjected to different cultural conditions were established. The production of infectious plaque-forming virus, ts mutants and interfering viral particles was determined at different times during 110 days after infection. Carrier cultures maintained in stationary conditions continuously released PFU while proliferating persistent cultures exhibited a cyclical pattern which tends to a rapid PFU disappearance. Concomitantly, in stationary cultures the production of interfering particles was delayed and was lower than in actively growing persistent cells. The metabolic state of the infected cells did not affect the release of ts mutants. The results suggest that a cellular function is involved on the regulation of Junin virus persistent infections.
