Respiratory syncytial virus: immunopathology and control.
Respiratory syncytial virus (RSV) is the primary cause of serious upper and lower respiratory tract infections in infants and children worldwide. RSV infection in infancy may lead to the onset of asthma or other health problems later in life. An effective vaccine is not yet available against RSV infection. Humans respond to RSV infection by mounting an immune response, but the antiviral immunity is incomplete, thus repeat RSV infections continue throughout life. The precise mechanism of RSV-induced infection and immunopathology remains unclear. The limited knowledge of RSV immunity is a major problem in designing a protective vaccine. In this review, the biology of RSV infection, its immunopathology, the role of innate and adaptive immunity, as well as the understanding of how to control RSV infection based on prophylactic and therapeutic approaches are discussed.
