...is to study viral variants with expanded host range. We have pursued this approach with two serotypes of rhinovirus. Wild-type human rhinovirus type 16 (HRV16) productively infects mouse ICAM-L cells =-=(33)-=-, but viral yields are low and cytopathic effect is absent. Variants of HRV16 with improved growth in these cells were selected by alternately passaging the virus between HeLa and mouse L cells produc...

... permissive nor susceptible to infection with most major group HRVs. While the block to replication of HRV14 and HRV16 in mouse L cells is relieved upon synthesis of hICAM-1, HRV39 fails to replicate =-=(17)-=-. Passage of HRV39 in mouse cells producing hICAM-1 led to the identification of a virus, HRV39/L, that can replicate in these cells (16). Amino acid changes in viral proteins 2B and 3A mediate HRV39 ...

Abstract - Add to MetaCart
Respiratory tract (RT) infections by members of the enterovirus (EV) genus of the Picornaviridae family are the most frequent cause for the common cold and a major factor in the exacerbation of chronic pulmonary diseases. The lack of a practical small-animal model for these infections has obstructed insight into pathogenic mechanisms of the common cold and their role in chronic RT illness and has hampered preclinical evaluation of antiviral strategies. Despite significant efforts, it has been difficult to devise rodent models that exhibit viral replication in the RT. This is due mainly to well-known intracellular host restrictions of EVs with RT tropism in rodent cells. We report the evolution of variants of the common-cold-causing coxsackievirus A21, an EV with tropism for the human intercellular adhesion molecule 1 (hICAM-1), through serial passage in the lungs of mice transgenic for the hICAM-1 gene. This process was accompanied by multiple changes in the viral genome, suggesting exquisite adaptation of hICAM-1-tropic enteroviruses to the specific growth conditions within the RT. In vivo mouse RT-adapted, variant coxsackievirus A21 exhibited replication competence in the lungs of hICAM-1 transgenic mice, providing a basis for unraveling EV-host interactions in the mouse RT. The common cold (acute nasopharyngitis) is a frequent ail-ment, primarily of viral etiology, recognized since antiquity. The incidence in adults and children ranges from 2 to 4 and 6

Similarly, poor replication of HRVs 16 and 39 in mouse L fibroblasts expressing hICAM-1 significantly improved upon acquisition of adaptation mutations in viral nonstructural proteins 2B, 2C, or 3A =-=(23, 24)-=-. We report here the generation of an hICAM-1-tropic EV strain with replication competence in the murine RT. Our efforts focused on the laboratory strain CAV21(Kuykendall), referred to as CAV21 here. ...

However, because cell entry does not necessarily result in lysis, as replication might be blocked intracellularly in some cell types =-=(9, 17, 40)-=-, this does not prove that HRV85 cannot bind ICAM-1-negative cells.
