Biology of viral satellites and their role in pathogenesis

Extraviral components that can influence the accumulation and pathogenesis of their associated helper viruses are known as ‘satellites’. The maintenance of satellites requires their ability to associate with their helper viruses. Satellites can be categorized as either satellite viruses or satellite nucleic acids based on their ability to encode capsid proteins. Understanding the biology of satellites is important since they are pathogenic to a wide range of plant, animal, and yeast organisms. Most satellites influence the pathogenesis of their helper viruses by altering the interaction between the host and helper virus. However, the molecular mechanism that governs the trilateral interaction between host, satellites, and helper virus remains largely unexplored. This review comprehensively describes details of the association and interaction of helper viruses with satellite viruses, satellite RNAs, and satellite DNAs, and their implications for pathogenesis.See it on Scoop.it, via Viruses, Immunology & Bioinformatics from Virology.uvic.ca
