Modulation of innate immune signalling pathways by viral proteins.
In recent years an explosion of information on the various strategies viruses employ to penetrate and hijack the host cell has led to an increased understanding of both viruses themselves and the host immune response. Despite their simplicity viruses have evolved a number of strategies to not only evade the host immune response but also modulate immune signalling to favour their replication and survival within the cell. The innate immune response provides the host with an early reaction against viruses. This response relies heavily upon the recognition of pathogen-associated molecular patterns (PAMPs) by a number of host pattern recognition receptors (PRRs), leading to activation of innate signalling pathways and altered gene expression. In this chapter we outline the signalling pathways that respond to viral infection and the various methods that viruses utilize to evade detection and modulate the innate immune response to favour their survival.
