英文摘要：

Killer cell immunoglobulin-like receptors （KIRs） which are mainly expressed on natural killer （NK） cells are implicated in many virus infections. However, it is unclear whether or not KIRs are associated with susceptibility to Epstein-Barr virus （EBV） infection related diseases. Therefore, the purpose of our study was to investigate possible correlation between polymorphisms of KIR genes and infectious mononucleosis （IM）/EBV-associated hemophagocytic Iymphohistiocytosis （EBV-HLH）. The polymorphisms of KIR genes were detected by polymerase chain reaction with sequence-specific primers （PCR-SSP）. The results would contribute to clarify the association of KIRs with EBV induced diseases, and provide new insights into the role of NK cells and innate immune response against viral infections and/or subsequent progression.
