Mechanism of entry of human rhinovirus 2 into HeLa cells. 1987

C Neubauer, and L Frasel, and E Kuechler, and D Blaas

Internalized human rhinovirus 2 (HRV2) undergoes a rapid conformational change leading to recognition by the C-determinant-specific monoclonal antibody 2G2. In the presence of the ionophore monensin, the virus accumulates in the cells in its native conformation and infection is strongly inhibited. At 20 degrees but not at 34 degrees the inhibitory effect of monensin can be overcome by a short incubation of the infected cells at low pH as late as 2 hr after inoculation. Incubation of infected cells at 20 degrees prior to addition of monensin permits virus synthesis to occur, depending on the time of preincubation.

UI MeSH Term Description Entries
D008985 Monensin An antiprotozoal agent produced by Streptomyces cinnamonensis. It exerts its effect during the development of first-generation trophozoites into first-generation schizonts within the intestinal epithelial cells. It does not interfere with hosts' development of acquired immunity to the majority of coccidial species. Monensin is a sodium and proton selective ionophore and is widely used as such in biochemical studies. Coban,Monensin Monosodium Salt,Monensin Sodium,Monensin-A-Sodium Complex,Rumensin,Monensin A Sodium Complex
D009940 Organoids An organization of cells into an organ-like structure. Organoids can be generated in culture, e.g., self-organized three-dimensional tissue structures derived from STEM CELLS (see MICROPHYSIOLOGICAL SYSTEMS). They are also found in certain NEOPLASMS. Organoid
D011487 Protein Conformation The characteristic 3-dimensional shape of a protein, including the secondary, supersecondary (motifs), tertiary (domains) and quaternary structure of the peptide chain. PROTEIN STRUCTURE, QUATERNARY describes the conformation assumed by multimeric proteins (aggregates of more than one polypeptide chain). Conformation, Protein,Conformations, Protein,Protein Conformations
D002213 Capsid The outer protein protective shell of a virus, which protects the viral nucleic acid. Capsids are composed of repeating units (capsomers or capsomeres) of CAPSID PROTEINS which when assembled together form either an icosahedral or helical shape.
