This study examines the effects of blocking the nectin-1 and Herpes Virus Entry Mediator (HVEM) receptors on Neuro-2a (N2a) cells in order to prevent HSV-1 infection. These two receptors have been identified as a primary and secondary mode of entry for HSV-1. Since there was some debate about the correct serum level to be used in growth media for healthy N2a cells, three concentrations (2%, 5%, 10%) were used to examine relative growth and neurite development, in addition to examining possible differences in infectivity levels in all other experiments. There was a difference in general morphology, with neurite abundance and …

To more closely mimic the in vivo progression of HSV-1 a novel in vitro method was created. In this study HEL-30 keratinocytes were infected with a 0.1 MOI of HSV-1 and plated unto a membrane with 8μm diameter pores. The membrane insert was then placed into culture wells that contained Neuro-2a cells (N2A). The neurites from the neuronal cells made cell-to-cell contact with the infected HEL-30 cells and the virus was transmitted into the neuronal cells. To determine if infection occurred in the N2A cells the cells were lysed and the lysate incubated with Vero cells to titrate virus plaque …

This study examined the effects of HSV-1 infection and IFN-γ treatment on Neuro-2A cells. HSV-1 induces expression of SOCS1 and SOCS3 in infected cells, inhibiting the ability of these cells to produce the pro inflammatory, antiviral cytokine IFN-γ (Nowoslawski and Benveniste, 2011). SOCS1 and SOCS3 levels were determined in IFN-γ-treated cells, virus-infected cells, and cells that were both IFN-γ-treated and virus-infected. Results were compared with untreated, uninfected control cells. Flow cytometry data analysis showed a slight decrease in SOCS1 and SOCS3 protein levels in cells treated with IFN-γ for 6 hours compared to control cells. A significant decrease in SOCS1 …
