A B-lymphocyte binding peptide from BNRF1 induced antibodies inhibiting EBV-invasion of B-lymphocytes

Epstein–Barr virus (EBV) infects human target cells mainly through gp350/220-CD21 and gp42-MHCII interactions; however, it has been shown that these interactions are dispensable for EBV-invasion of susceptible cells, suggesting that other viral proteins are involved in this process. It is probable t...
