Structural components of the arenavirus Pichinde

Abstract: Pichinde virions grown in monolayers of BHK-21 cells were found to contain three major species of virion proteins as described previously (Ramos et al., J. Virol. 10:661-667, 1972). Two of the proteins were glycosylated (G1, molecular weight = 64,000; G2, molecular weight = 38,000) and were present in similar proportions on the outer surface of the virions. A third protein (N, molecular weight = 66,000) was not glycosylated and, in association with the viral RNA species, was the major protein component of the … Show more

“…In ultrathin sections of virus particles or virus infected cells, internal structural details concerning the arrangement of the nucleocapsid have been difficult to resolve. Only after negative staining, threadlike circular nucleocapsid strands could be observed after solubilization of the virion envelope by detergents (Vezza et al 1977;Compans 1993). Assembly, maturation and egress of arenaviruses occur by budding at the plasma membrane where the clubshaped surface projections of 6-10 nm in length are visible on the virus envelope (for review see Dubois-Dalcq, Holmes & Rentier 1984;Compans 1993;Southern 1996;King et al 2012).…”

“…En las microfotografías electrónicas el interior de los viriones aparece constituido por una materia amorfa constituida principalmente por citoplasma celular con gránulos electrondensos en cantidad variable, que son ribosomas. Su origen celular fue demostrado tanto por métodos genéticos como bioquímicos (Pedersen, 1970a(Pedersen, , 1970b(Pedersen, , 1970cCarter et al, 1973;Farber y Rawls, 1975;Anón et al, 1976;Vezza et al, 1977Vezza et al, , 1978. El rRNA es metilado y su incorporación en los viriones puede inhibirse por actinomicina D (Carter et al, 1973;Rawls et al, 1973).…”
