Monolayers of NB41A3 (MNB) cells were exposed to pharmacologic doses of dexamethasone (DXM). After 24-h, the cells were infected with herpes simplex virus type 1 (HSV-I) at a multiplicity of infection (m.0.i.) = 0.1. After every 24-h period, extracellular and intracellular virus aliquots were collec

β¦ Synopsis
In this study, the effect of the synthetic glucocorticoid hormone dexamethasone (DXM) on HSV replication was studied in a DXM receptor-positive mouse neuroblastoma (NB) cell line. In cells treated with 10-7M DXM and then infected with HSV, there was a statistically significant 9-1 8-fold increase in the amount of virus produced in these cells compared to untreated controls. Adsorption kinetic studies with HSV were performed in DXM-treated NB cells and untreated controls. It was found that there was a significant increase in the adsorption rate of HSV in the DXM-treated cells as compared with the controls. During the course of these studies, a strain of NB cells was noted to have lost its ability to stimulate HSV replication

## Abstract ## BACKGROUND In preclinical models, infection of tumors by oncolytic strains of herpes simplex virus 1 (HSVβ1) resulted in the destruction of tumor cells by viral replication and release of progeny virion that infected and destroyed adjacent tumor cells. However, complete tumor regres
