Use of the Herpes Simplex Viral Genome to Construct Gene Therapy Vectors
Abstract
Herpes simplex virus (HSV) is an enveloped double-stranded DNA virus (see Fig. 1A-reviewed in ref. 1). The mature virion consists of the following components:
1.  A trilaminar lipid envelope, in which are embedded 10 viral glycoproteins-these are responsible for several functions including receptor-mediated cellular entry (25).
2.  A matrix of proteins, the tegument, which form a layer between the envelope and the underlying capsid. Functions of the tegument proteins include: induction of viral gene expression (68); shutoff of host protein synthesis immediately following infection (912); virion assembly functions.
3.  An icosadeltahedral capsid, typical of the herpesvirus family (13,14).
4.  A core of toroidal double-stranded DNA (dsDNA) (1416).
