Zusammenfassung
Herpes genitalis wird durch Herpes-simplex-Viren (HSV) hervorgerufen und gehört zu den häufigsten Geschlechtskrankheiten weltweit. Bislang steht noch kein effektiver und sicherer Impfstoff gegen HSV zur Verfügung. CJ9-gD ist ein absolut replikationsdefektes rekombinantes HSV-1, das in Koinfektionen die Replikation von Wildtyp-HSV-1/-2 blockiert (dominant-negativer Effekt) und eine frühe und starke Expression des HSV-Hauptantigens Glykoprotein D gewährleistet. Die Immunisierung mit CJ9-gD induziert starke und lang anhaltende humorale und TH1-gewichtete zelluläre Immunantworten gegen HSV-1 und HSV-2 bei Mäusen und schützt diese deutlich gegen genitale Infektionen mit HSV-1 oder HSV-2. Bei Meerschweinchen erzielt die Immunisierung mit CJ9-gD einen signifikanten Schutz gegen primäre und rezidivierende genitale HSV-2-Infektion sowie eine Reduktion der latenten Infektion.
Abstract
Genital herpes caused by herpes simplex virus (HSV) is one of the most common sexually transmitted diseases worldwide. Currently, no safe and effective vaccine against HSV is available. CJ9-gD is a completely replication-defective HSV-1 recombinant which inhibits replication of wild-type HSV-1/-2 in co-infected cells (dominant-negative effect). Moreover, it expresses high levels of HSV-1 major antigen glycoprotein D (gD). Immunization with CJ9-gD induces strong and long-lasting humoral and Th1-like cellular immune responses against both HSV-1 and HSV-2 in mice protecting immunized animals significantly against genital challenge with HSV-1 or HSV-2. Guinea pigs immunized with CJ9-gD were significantly protected against primary and recurrent HSV-2 genital disease and latent infection.
