Targeted delivery of DNA encoding herpes simplex virus type-1 glycoprotein D enhances the cellular response to primary viral challenge

Intravenous injection of plasmid DNA encoding herpes simplex virus type-1 glycoprotein D (gD-1) complexed with asialoorosomucoid-poly-L-lysine (gD-ASOR) targets foreign DNA to the liver, leading to hepatic expression of gD-1. BALB/c mice were given two intravenous injections of gD-ASOR, pBK-ASOR (plasmid lacking the gD-1 gene but complexed with ASOR), or PBS. The skin was inoculated with 1 x 10(4) PFU of HSV-1 or sham-inoculated, and analyzed...
