Isolated epstein-barr virus bzlf2 proteins that bind mhc class ii beta chains

摘要

Isolated viral proteins, and pharmaceutical compositions made therefrom, are disclosed which are capable of binding to a beta chain of a Class II Major Histocompatibility Complex antigen, thereby functioning to inhibit an antigen-specific response. The viral proteins also have superantigen-like activity, and inhibit EBV infection.
