Abstract

Background Human rhinovirus (HRV) infections are the predominant cause of the common cold and are associated with exacerbations of asthma. Nitric oxide (NO) may play an important role in host defense by means of its potent antiviral properties.Objective We sought to determine whether epithelial expression of type 2 nitric oxide synthase (NOS 2), which produces NO, is induced on rhinovirus infection in vitro and in vivo.Methods Primary cultures of human airway epithelial cells were infected with HRV-16, and NOS 2 mRNA expression was assessed by conventional and real-time RT-PCR and NOS 2 protein by using Western blot analysis. Human subjects were also infected with HRV-16 in vivo, and mRNA for NOS 2 was assessed in nasal epithelial scrapings obtained before and after infection.Results NOS 2 mRNA levels increased within 8 hours after HRV-16 infection of cultured cells and remained elevated up to 48 hours after infection. NOS 2 protein was elevated at 24 hours. Induction of NOS 2 did not occur with UV-inactivated HRV-16 but could be reproduced by using double-stranded RNA, indicating that induction was dependent on viral replication. Increased NOS 2 expression was also observed in nasal epithelial scrapings during symptomatic colds.Conclusion Increased epithelial expression of NOS 2 mRNA occurs as part of the host response to HRV infection in vitro and in vivo. Given the antiviral effects of NO, we speculate that increased host production of NO may play an important role in host defense during HRV infections.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
