Study on the Cytotoxic T Lymphocytes Clone Specific for the Nucleocapsid Protein of Hantaan Virus from Peripheral Blood in Patients with Hemorrhagic Fever with Renal Syndrome
In order to elucidate the molecular and immunological mechanisms as well as the pathogenesis of hemorrhagic fever with renal syndrome (HFRS), the CD8+ cytotoxic T lymphecytes (CTL) clone was established directly from peripheral blood mononuclear cells (PBMC) of patients with HFRS. The activities of CTL were detected as usual with EBV-transformed lymphoblastoid cell line (BLCL) as target cells. The results showed that the CTL clone could recognized and killed the targetcells with specificity of nucleocapsid protein of Hantaan virus (HTNVNP) with the cytotoxicity percentages of 50.2%,25.4% and 39.0% respectively. These results demonstrated that the antigenic epitopes of HTNVNP mainly located on the C-temainal of the viral nucleocapsid protein.
