Abstract:
Human cytomegalovirus (HCMV) is a highly prevalent infection and it has become a paradigm for viral immune evasion due to its unique multitude of immune-modulatory strategies on host innate and adaptive immune response.Following primary infection,CMV can persist as a subclinical,recurrent infection for the lifetime of an individual because human immune system is unable to clarify.However,the immune evasion mechanism of CMV remains unclear.Recent data has revealed an astounding variety of methods in immune evasion to suppress host immune system,including inhibiting antigen presentation on infected cell surfaces to protect against T cell recognition and regulating the balance between natural killer cell inhibitory/activating receptor and ligand pairs to avoid NK cell attack.This review summarizes the latest literature regarding how CMV encodes a multitude of immune modulatory mechanisms devoted to escaping the host antiviral response,presents the future perspective of immunotherapy,and provides references for in-depth understanding of the immune evasion mechanisms leading to the control of CMV.
