According to the results of immunoinformatics analysis, the obvious variation of HLA-A2 associated T cell epitopes between SARS vires and HCoV-229E was found as follows： （1） Disappearance of HIA-A2 binding site; （2） variation sequence on the HLA-A2 associated epitope; （3） emergence of a new HLA-A2 associated epitope. The immunoinfomatics results were evidenced by T2 cell binding assay, ELISPOT and DimerX staining. In conclusion, immunoinformatics is a useful method to analyze the immunological character of a new finding infectious pathogen, like SARS-CoV. These findings of immunoinformatics are confirmed by lab and clinical experiments. In this case, immunoinformatics seems a very useful tool in the study of immune response and the evaluation of vaccine in infectious diseases, such as SARS.展开更多
