Intraocular varicella-zoster virus (VZV) and HSV type 1 (HSV-1) infections cause sight-threatening uveitis. The disease is characterized by an intraocular inflammatory response involving herpesvirus-specific T cells. T cell reactivity to the noncausative human alphaherpesvirus (αHHV) is commonly detected in the affected eyes of herpetic uveitis patients, suggesting the role of cross-reactive T ...

Herpes simplex virus type 2 (HSV-2) is transmitted through the genital mucosa during sexual encounters. In recent years, HSV-1 has also become commonly associated with primary genital herpes. The mechanism of viral entry of HSV-1 and HSV-2 in the female genital tract is unknown. In order to understand the molecular interactions required for HSV entry into the vaginal epithelium, we examined the...

Previous studies have revealed that herpes simplex virus type 1 (HSV-1) corneal stromal lesions do not develop in the absence of a cell-mediated immune (CMI) response to HSV-1 antigens. HSV-1 glycoprotein C (gC) has been shown to play an important role in the induction of the cytotoxic T lymphocyte (CTL) response to HSV-1 infections at anatomical sites other than the eye. Here we report that a ...

Multiple cell surface molecules (herpesvirus entry mediator [HVEM], nectin-1, nectin-2, and 3-O-sulfated heparan sulfate) can serve as entry receptors for herpes simplex virus type 1 (HSV-1) or HSV-2 and also as receptors for virus-induced cell fusion. Viral glycoprotein D (gD) is the ligand for these receptors. A previous study showed that HVEM makes contact with HSV-1 gD at regions within ami...

PURPOSE To investigate the therapeutic efficacy of periocular vaccination with herpes simplex virus (HSV) recombinant glycoprotein D from HSV-1 (gD1) or HSV-2 (gD2) in decreasing HSV-induced recurrent dendritic keratitis and HSV-induced recurrent ocular shedding in rabbits latently infected with HSV-1. METHODS Rabbits latently infected with HSV-1 were vaccinated periocularly (by subconjunctiv...

A multitude of different polymerase chain reactions (PCRs) have been described for detection and typing of Herpes simplex virus (HSV). This paper compares two PCRs coupled to enzymatic restriction (PCR/RFLP) to detect and type HSV. A primers set was designed to amplify a HSV DNA fragment from UL30 and UL 15 genes. Typing was done by restriction of the UL30 and UL15 amplicons with Ava II and Hpa...

We determined type-specific antibodies to herpes simplex virus type 1 (HSV-1) and type 2 (HSV-2) by an indirect enzyme-linked immunosorbent assay, using as antigens HSV-1 glycoprotein gC-1 and a HSV-2-specific polypeptide purified on affinity columns of monoclonal antibodies. All sera were initially screened for HSV antibodies by the enzyme-linked immunosorbent assay with a pool of Triton X-100...

PURPOSE Primary and recurrent infections of the cornea by herpes simplex virus 1 (HSV-1) are important causes of eye disease. Three unrelated classes of glycoprotein D receptors for HSV-1 entry into cells have been identified. This study was undertaken to uncover the relative significance of nectin-1 as an entry receptor in corneal infection and HSV-1 spread to the trigeminal ganglia (TG), a si...

Apoptosis of virus-infected cells occurs either as a direct response to viral infection or upon recognition of infection by the host immune response. Apoptosis reduces production of new virus from these cells, and therefore viruses have evolved inhibitory mechanisms. We previously showed that laboratory strains of herpes simplex virus type 1 (HSV-1) protect infected cells from apoptosis induced...

conclusions advocacy and publicity to raise awareness of the potential public health impact of hsv and hiv co-infection in nigeria, where anti-hsv testing is not generally performed in all populations, is therefore recommended. background herpes simplex virus 1 (hsv-1) is normally associated with orofacial (orolabial) infections and encephalitis, whereas hsv-2 usually causes genital infections ...
