Transgenic mouse-derived human monoclonal antibodies targeting EBV gp350 and gp42 provide basis for therapeutic development.

ABSTRACT: Epstein-Barr virus (EBV) causes infectious mononucleosis and contributes to neurodegenerative disorders and malignancies, particularly in immune-compromised hosts. Transplant patients face high risk of post-transplant lymphoproliferative disease, a life-threatening EBV-driven lymphoma. There are no EBV-specific vaccines or treatments; however, neutralizing antibodies against EBV glycoproteins may offer utility as therapeutic agents. EBV entry into B cells involves gp350, which binds complement receptors, and gp42, which engages HLA class II to trigger fusion. Most existing monoclonal antibodies (mAbs) against these antigens are non-human, limiting clinical use. Using a transgenic mouse model, we generate two gp350 and eight gp42 genetically human neutralizing mAbs that block receptor bindi
