Abstract
Bats are the natural reservoir host for a number of zoonotic viruses, including Hendra and Nipah viruses of Henipavirus genus, which are highly pathogenic in humans and numerous other mammalian species. Despite being infected, bats present limited signs of disease but still retain the ability to transmit the infection to other susceptible hosts, presenting thus a permanent source of new viral outbreaks. Different mechanisms have evolved in fruit bats permitting them to efficiently control the Henipavirus infection. These mechanisms likely allow bats to establish an adequate equilibrium between viral tolerance and antiviral defense, enabling them thus to avoid both uncontrollable virus expansion as well as immunopathology linked to excessive antiviral responses.
期刊介绍:
Current Opinion in Virology (COVIRO) is a systematic review journal that aims to provide specialists with a unique and educational platform to keep up to date with the expanding volume of information published in the field of virology. It publishes 6 issues per year covering the following 11 sections, each of which is reviewed once a year: Emerging viruses: interspecies transmission; Viral immunology; Viral pathogenesis; Preventive and therapeutic vaccines; Antiviral strategies; Virus structure and expression; Animal models for viral diseases; Engineering for viral resistance; Viruses and cancer; Virus vector interactions. There is also a section that changes every year to reflect hot topics in the field.
