Abstract

Antigenic analysis of Herpes simplex type 2 virus was performed and its major antigen was localized using an immunoelectron microscopy. Antigens of 32, 43, 59 and 69 kDa were constantly expressed during the course of infection for 48 hr in the infected Vero cell. An antigen of 51 kDa was turned out to be the major one in inducing a immune response in Western-blot analysis. The 51 kDa antigen was localized on the surface of HSV-2 by immunoelectron microscopy using colloidal golds and anti-HSV 2 polyc1onal antibody. Immunofluorescence assay indicated that viral antigens were found throughout the infected cell and, especially, on the surface of the cell.

단순포진 바이러스 감염을 유발하는Herpes simplex2형 바이러스의 감염에 관여하는 항원들과 중화항체 생산을 유발하는 주요 항원들의 위치를 확인하였다. Vero cell에 감염하였을 때 48시간 동안 31, 43, 59, 69 kDa 바이러스 항원들이 지속적으로 발현되었으며, 감염된 쥐에서 생산한 항체와의 반응에서는 51 kDa 항원이 가장 강한 반응을 보였다. 면역전자현미경으로 위치를 확인한 결과 colloidal gold가 바이러스 표면에 발견되는 것으로 보아 이 항원이 바이러스 표면에 존재하고 있는 것으로 확인되었다. 형광현미경 분석은 이 항원들이 감염된 세포 내에서 전반적으로 발견되었고 특히 세포 표면에서 많이 발현되고 있었다.
