Pneumonitis in human cytomegalovirus infection

Abstract

Human cytomegalovirus (HCMV) is a β herpes virus with a double stranded DNA genome of 240kbp. The virus is prevalent and establishes a latent infection in most adults. HCMV is an opportunistic pathogen for patients with impaired cellular immunity. HCMV pneumonia is a common presentation of HCMV disease in immunocompromised patients. The incidence of HCMV pneumonitis can be as high as 90% in lung transplant recipients. This paper takes a fresh look at the challenging perspectives of molecular, immunologic, cellular, diagnostic, clinical, and therapeutic characteristics of HCMV infection as future targets for development of antiviral strategies.
