The Epstein-Barr virus receptor on two nasopharyngeal carcinoma model cell lines.
It was reported that the OKB7 monoclonal antibody to C3d receptor could directly inhibit Epstein-Barr virus (EBV) attachment to and infection of B-lymphocytes. So we tested whether the OKB7 could inhibit superinfection of two epithelial NPC model cell lines (D98/HR-1 and NPC-KT) with EBV. Pretreatment of B-lymphocytes with the OKB7 significantly inhibits EBV infection. However, pretreatment with the OKB7 had no effect on superinfection of D98/HR-1 and NPC-KT cells. These data suggest that an EBV receptor, unrelated to C3d receptor, exists.
