Most human Herpesvirus infect placental cells and may be harmful in pregnancy, leading to obstetrical and/or neonatal complications. Although a correlation between human herpesvirus 8 (HHV-8) infection and abortion or low birth weight in children has been reported [1, 2] presently no information has been published regarding HHV-8 tropism for placenta.
Materials and methods
In this study, a placenta histoculture system was used to evaluate the susceptibility of placental cells to “in vitro” HHV-8 infection. Quantitative detection of HHV-8 was performed by real-time PCR, and virus expression was evaluated by immunohistochemistry for latent and lytic HHV-8 antigens.
We here demonstrated for the first time that HHV-8, like other human herpesviruses, may productively infect placental cells in vitro, thus providing evidence that this phenomenon might influence vertical transmission and pregancy outcome in HHV-8-infected women.
