Mechanism of entry of human rhinovirus 2 into HeLa cells

Virology. 1987 May;158(1):255-8. doi: 10.1016/0042-6822(87)90264-9.

Abstract

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.
