Abstract:
The entry of herpes simplex virus (HSV) into an oral epithelial cell line, primary normal human oral keratinocytes (NHOK) and gingival fibroblasts (GF) was examined. Infection of these cells by HSV-1 and HSV-2 was blocked by heparin. Further examination indicated that heparin reduced viral attachment but not penetration. Moreover, neomycin inhibited HSV-1 infection more effectively than HSV-2 infection in GF, but not in NHOK. In conclusion, our results elucidated some aspects of the HSV entry process into oral cells and revealed some differences in HSV entering into NHOK and GF.
