Activation and counteraction of antiviral innate immunity by KSHV: an update

Xiaoqin Wei;Ke Lan;State Key Laboratory of Virology, College of Life Sciences, Medical Research Institute, Wuhan University;  
The innate immune responses triggering production of type I interferons and inflammatory cytokines constitute a nonspecific innate resistance that eliminates invading pathogens including viruses. The activation of innate immune signaling through pattern recognition receptors (PRRs) is by sensing pathogenassociated molecular patterns derived from viruses. According to their distribution within cells, PRRs are classified into three types of receptors:membrane, cytoplasmic, and nuclear. Kaposi’s sarcomaassociated herpesvirus (KSHV), a large DNA virus, replicates in the nucleus. Its genome is protected by capsid proteins during transport in the cytosol. Multiple PRRs are involved in KSHV recognition. To successfully establish latent infection, KSHV has evolved to manipulate different aspects of the host antiviral innate immune responses. This review presents recent advances in our understanding about the activation of the innate immune signaling in response to infection of KSHV. It also reviews the evasion strategies used by KSHV to subvert host innate immune detection for establishing a persistent infection.
