Herpes Simplex Virus Type 2–Infected Dendritic Cells Produce TNF-a, Which Enhances CCR5 Expression and Stimulates HIV Production from Adjacent Infected Cells

Herpes simplex virus type 2-infected dendritic cells produce TNF-α, which enhances CCR5 expression and stimulates HIV production from adjacent infected cells.

Prior HSV-2 infection enhances the acquisition of HIV-1 >3-fold. In genital herpes lesions, the superficial layers of stratified squamous epithelium are disrupted, allowing easier access of HIV-1 to Langerhans cells (LC) in the epidermis and perhaps even dendritic cells (DCs) in the outer dermis, as well as to lesion infiltrating activated T lymphocytes and macrophages. Therefore, we examined t...

Up-Regulation of Integrinsn α2β1 and α3β1 Expression in Human Foreskin Fibroblast Cells after In-Vitro Infection with Herpes Simplex Virus Type 1

The interaction of Herpes Simplex Virus type 1 (HSV-1) with human fetal foreskin fibroblast (HFFF) cell was studied using a recent isolate of HSV-1 which was propagated in Hep-2 cells. HFFF cells were challenged with HSV-1 with a multiplicity of infection (MOI) of 1 virus/cell for 24 hours. Flow cytometric analysis demonstrated that HSV-1 challenged HFFF cells expressed increased levels of α2β1...

Effects of Sodium Valproate on the Replication of Herpes Simplex Virus Type 1: An in Vitro Study

Background: Sodium valproate, an anticonvulsant drug, is reported to stimulate Human Immunodeficiency Virus type 1 and Human cytomegalovirus replication. Since epileptic patients undergoing sodium valproate therapy may suffer from various virus infections, the effect of this drug on replication of viruses especially those affecting neuronal tissues such as Herpes simplex virus type 1 is worthy ...

Seroepidemiology of herpes simplex virus type 2 (HSV2) in HIV infected patients in Kermanshah-Iran

Background: HSV2 has an important role in acquiring and transmitting HIV through genital ulcers. This study was conducted to determine the prevalence of this virus in HIV infected subject in Kermanshah, Iran. Methods: This descriptive study was performed among 170 HIV positive patients (case group) and 165 non-HIV cases (control group)) referred to Behavioral Counseling Center of Kermanshah, we...
