Herpes simplex virus-1 (HSV-1) is a ubiquitous virus which is implicated in diseases ranging from self-curing cold sores to life-threatening infections. The 2500 Å diameter herpes virion is composed of a glycoprotein spike containing, lipid envelope, enclosing a protein layer (the tegument) in which is embedded the capsid (which contains the dsDNA genome). The B-, and A- and C-capsids, representing different morphogenetic stages in HSV-1 infected cells, are composed of 7, and 5 structural proteins respectively. The three capsid types are organized in similar T=16 icosahedral shells with 12 pentons, 150 hexons, and 320 connecting triplexes. Our previous 3D structure study at 26 Å revealed domain features of all these structural components and suggested probable locations for the outer shell proteins, VP5, VP26, VP19c and VP23. VP5 makes up most of both pentons and hexons. VP26 appeared to bind to the VP5 subunit in hexon but not to that in penton.

Confirmation of herpes simplex virus (HSV) from genital lesions of obstetrical (OB) patients may affect both the management of the delivery and of the neonate.(l,2) During 1992 and 1993, 4,450 genital specimens from OB patients were submitted in viral transport media for herpes culture. The specimens were inoculated into MRC-5, Vero, and A-549 tissue culture tubes, incubated, and examined daily for 7 days for cytopathic effect (CPE). The original specimens were frozen at −70° C until final reports were issued. Culture tubes with CPE were tested by the Dupont Herpchek enzyme immuno assay (EIA) to confirm the presence of herpes simplex virus (HSV). (3,4) 170 OB patient specimens were positive by culture and confirmed by EIA.There were also 63 cultures exhibiting CPE ressembling HSV which were negative by EIA testing, which failed to pass in fresh tissue culture cells or progress to more enhanced CPE in culture. These original specimens were screened by electron microscopy after direct ultracentrifugation employing the Beckman airfuge with the EM 90 rotor on to formvar carbon-coated 300 mesh copper grids and negatively stained with 2% PTA.

SummaryHerpes simplex virus (HSV) infection is histopathologically associated with vascular injury, fibrinoid necrosis and inflammatory cell infiltrates. We have previously shown in vitro that HSV infection of human umbilical vein endothelial cells (HUVEC) promotes a procoagulant phenotype manifest by the induction of tissue factor, the loss of thrombomodulin, and an increase in platelet adhesion. In these studies we examined the effects of HSV infection on HUVEC plasminogen activator inhibitor type 1 (PAI-1) and tissue plasminogen activator (t-PA). HSV infection caused the loss of PAI-1 in the extracellular matrix (ECM) and that released into the supernatant of HUVEC. Both activity and antigen levels of the Serpin inhibitor are diminished as a result of HSV infection. The loss of inhibitor is not secondary to diminished vitronectin (Vn), the primary binding protein of PAI-1 in the ECM, but appears to be secondary to decreased synthesis at the RNA level. Tissue plasminogen activator (t-PA). synthesis is also decreased in endothelial HSV infection. PAI-1 loss may further promote a procoagulant phenotype in HSV infection in vivo.
