Intrastrain variants of herpes simplex virus type 1 isolated from a neonate with fatal disseminated infection differ in the ICP34.5 gene, glycoprotein processing, and neuroinvasiveness.

Two intrastrain variants of herpes simplex virus type 1 (HSV-1) were isolated from a newborn with fatal disseminated infection. A small-plaque-producing variant (SP7) was the predominant virus (\textgreater99%) in the brain, and a…

Ligand epitope antigen presentation system vaccines against herpes simplex virus.

The Ligand Epitope Antigen Presentation System (L.E.A.P.S.) approach to vaccine development allowed construction of immunogens from defined T cell epitopes from herpes simplex virus (HSV) proteins that conferred protection against lethal challenge by…

Synthesis of radioactive single-stranded DNA probes using asymmetrical PCR and oligonucleotide random priming.

Strain-dependent structural variants of herpes simplex virus type 1 ICP34.5 determine viral plaque size, efficiency of glycoprotein processing, and viral release and neuroinvasive disease potential.

The ability of certain strains of herpes simplex virus type 1 (HSV-1) to cause encephalitis or neuroinvasive disease in the mouse upon peripheral infection is dependent on a combination of activities of specific forms of viral proteins. The…

Analysis of the thymidine kinase of a herpes simplex virus type 1 isolate that exhibits resistance to (E)-5-(2-bromovinyl)-2'-deoxyuridine.

The mechanism responsible for the decreased sensitivity of a clinical herpes simplex virus type 1 (HSV-1) isolate, HSV-145, to (E)-5-(2-bromovinyl)-2'-deoxyuridine (BVDU) was examined. Measurements of 50% inhibitory doses of several drugs…

Immunization with a LEAPS heteroconjugate containing a CTL epitope and a peptide from beta-2-microglobulin elicits a protective and DTH response to herpes simplex virus type 1.

A ligand epitope antigen presentation system (LEAPS) heteroconjugate vaccine containing a CTL epitope (H1) from the HSV-1 immediate early protein ICP27 (322-332) and a peptide sequence (J) from beta-2-microglobulin (35-50) elicited protection from…

A L.E.A.P.S. heteroconjugate vaccine containing a T cell epitope from HSV-1 glycoprotein D elicits Th1 responses and protection.

The L.E.A.P.S. heteroconjugate vaccine antigen (JgD), composed of a T cell epitope from glycoprotein D (gD(8-23)) of herpes simplex virus (HSV) linked with a peptide sequence from beta-2-microglobulin (aa38-50), elicited protection against lethal…

Changes in BiP (GRP78) levels upon HSV-1 infection are strain dependent.

BiP (grp78) is a chaperone protein which can also regulate the unfolded protein response of the cell. Levels of BiP increased in cells infected by the small plaque producing, cell associated, neuroinvasive strains of HSV-1 (SP7, 490) but decreased in…

Resveratrol inhibition of herpes simplex virus replication.

Resveratrol, a phytoalexin, was found to inhibit herpes simplex virus types 1 and 2 (HSV-1 and HSV-2) replication in a dose-dependent, reversible manner. The observed reduction in virus yield was not caused by the direct inactivation of HSV by…

J-LEAPS vaccines initiate murine Th1 responses by activating dendritic cells.

The Ligand Epitope Antigen Presentation System (LEAPS) converts a peptide containing a T cell epitope as small as 8 amino acids into an immunogen and directs the nature of the subsequent response. Tandem synthesis of the J peptide (a peptide from the…

Resveratrol suppresses nuclear factor-kappaB in herpes simplex virus infected cells.

Resveratrol inhibits herpes simplex virus (HSV) replication by an unknown mechanism. Previously it was suggested that this inhibition may be mediated through a cellular factor essential for HSV replication [Docherty, J.J., Fu, M.M., Stiffler, B.S.,…

Effect of resveratrol on herpes simplex virus vaginal infection in the mouse.

Resveratrol (3,5,4'-trihydroxystilbene) is a natural component of certain foods, such as grapes, that, when topically applied, has been shown to limit HSV-1 lesion formation in the skin of mice [Antiviral Res. 61:19-26, 2004]. To determine if it is…

Effect of topically applied resveratrol on cutaneous herpes simplex virus infections in hairless mice.

Resveratrol (3,5,4'-trihydroxystilbene) is a natural component of certain foods, such as grapes, that has been shown to have anti-herpes simplex virus (HSV) activity in vitro. To determine if it is active in vivo, the abraded epidermis of SKH1 mice…

The ability of an HSV strain to initiate zosteriform spread correlates with its neuroinvasive disease potential.

The requirements for disease development in the mouse epidermal scarification-zosteriform model of HSV infection are likely to parallel those required for primary HSV disease of humans. HSV-1 strains, which are neuroinvasive in the mouse footpad…

HSV-2 ICP34.5 protein modulates herpes simplex virus glycoprotein processing.

The ICP34.5 gene from HSV-2 strain 333 was cloned and, when expressed in Vero cells, enhanced the efficiency and extent of glycoprotein processing of glycoprotein C (gC1), a representative viral glycoprotein, during infection with

Multiple mechanisms for HSV-1 induction of interferon alpha production by peripheral blood mononuclear cells.

UV-inactivated, infectious, and other forms of herpes simplex virus 1 (HSV-1) induced interferon (IFN) production by different routes in myeloid origin mononuclear cells (MOMC) (consisting predominantly of monocytes). GM-CSF activated the MOMC…

A block in glycoprotein processing correlates with small plaque morphology and virion targetting to cell-cell junctions for an oral and an anal strain of herpes simplex virus type-1.

The characteristics of two clinical isolates of HSV-1 obtained from an oral (424) and an anal (490) lesion were compared with the highly passaged KOS strain. In contrast to KOS, the clinical isolates produced small plaques, were more cell-associated…

Distribution and origin of corticotropin-releasing factor-immunoreactive axons in the female rat lumbosacral spinal cord.

Corticotropin-releasing factor (CRF) is a neuropeptide traditionally known for its hormonal role in the hypothalamic/pituitary/adrenal stress axis. However, CRF has been reported in axons in sites that may be considered outside of the direct stress…
