Pneumoviruses are single-stranded, negative-sense, nonsegmented RNA
viruses of the family Paramyxoviridae, subfamily
Pneumovirinae, and include pathogens that infect humans
(respiratory syncytial virus and human metapneumovirus), domestic
mammals (bovine, ovine, and caprine respiratory syncytial viruses),
rodents (pneumonia virus of mice), and birds (avian metapneumovirus).
Among the topics considered in this review are recent studies focused
on the roles of the individual virus-encoded components in promoting
virus replication as well as in altering and evading innate antiviral
host defenses. Advances in the molecular technology of pneumoviruses
and the emergence of recombinant pneumoviruses that are leading to
improved virus-based vaccine formulations are also discussed. Since
pneumovirus infection in natural hosts is associated with a profound
inflammatory response that persists despite adequate antiviral therapy,
we also review the recent experimental treatment strategies that have
focused on combined antiviral, anti-inflammatory, and immunomodulatory
approaches.
