title: Antigenic cross-reactions among herpes simplex virus types 1 and 2, Epstein-Barr virus, and cytomegalovirus.
abstract: Polyvalent rabbit antisera against herpes simplex virus type 1 and 2 (HSV-1 and HSV-2), cytomegalovirus (CMV), and Epstein-Barr virus (EBV), monospecific antisera against affinity-purified HSV-2 glycoproteins gB and gG, and a panel of monoclonal antibodies against HSV and EBV proteins were used to analyze cross-reactive molecules in cells infected with the four herpesviruses. A combination of immunoprecipitation and Western blotting with these reagents was used to determine that all four viruses coded for a glycoprotein that cross-reacted with HSV-1 gB. CMV coded for proteins that cross-reacted with HSV-2 gC, gD, and gE. Both CMV and EBV coded for proteins that cross-reacted with HSV-2 gG. Antigenic counterparts to the p45 nucleocapsid protein of HSV-2 were present in HSV-1 and CMV, and counterparts of the major DNA-binding protein and the ribonucleotide reductase of HSV-1 were present in all the viruses. The EBV virion glycoprotein gp85 was immunoprecipitated by antisera to HSV-1, HSV-2, and CMV. Antisera to CMV and EBV neutralized the infectivity of both HSV-1 and HSV-2 at high concentrations. This suggests that cross-reactivity between these four human herpesviruses may have pathogenic as well as evolutionary significance.
