Control Of Herpes Simplex Virus Replication

Herpes simplex virus type 1 (HSV-1) is capable of causing a latent infection in sensory neurons that lasts for the lifetime of the host. The innate immune response limits viral replication in the periphery and presents antigen to the nave lymphocytes to activate the adaptive immune response.

What is readily apparent is that many of the known functions encoded by the virus are directed toward total control of the infected cell. Herpes simplex virus 1 and 2 (HSV-1 and HSV-2) , also known as human herpesvirus 1 and 2 (HHV-1 and HHV-2) , are two members of the herpesvirus family, Herpesviridae, that infect humans. In an outbreak, the virus in a nerve cell becomes active and is transported via the neuron’s axon to the skin, where virus replication and shedding occur and cause new sores.

The Strategy Of Herpes Simplex Virus Replication And Takeover Of The Host Cell

They are also involved in the control of beta protein synthesis. Herpes simplex viruses (HSVs) can cause a variety of infections, including genital herpes. 8, Local viral replication and immunologic responses result in formation of a herpetic vesicle or lesion. Translational Control in Herpes Simplex Virus-infected Cells. To ensure high-level production of the polypeptides required for their lytic replication, multiple independent gene products expressed by the model -herpesvirus HSV-1 effectively seize control of critical host cell translational control pathways.

In addition to controlling viral replication, IRF-3 and -7 therefore play coordinating roles in modulation of inflammation during HSV infection. Replication in the peripheral nervous system leads to virus spreading back to the skin at sites within the inoculated dermatome that are distinct from the site of inoculation producing a characteristic zosteriform lesion (Figure 1a). One of the hallmarks of herpes simplex virus (HSV) infection is the dramatic reorganization of the infected cell nucleus leading to the formation of large globular replication compartments in which gene expression, DNA replication, and encapsidation occur (1, 2 and references therein) (see Figure 1). The formation of replication compartments follows an ordered assembly process, resulting in a drastic remodeling of the nucleus 1, 2, 1013. Herpes simplex virus genome must enter the cell for the initiation of infection. HSV initiates rounds of DNA replication at one or all of the three origins of replication (Ori 1, Ori 2, and Ori 3). A family of molecules known as NTS enzyme inhibitors are promising candidates for new herpes virus treatments, a new study shows. Derivatives on Herpes Simplex Virus Replication in Nervous Cells In Vitro.

Synergistic Control Of Herpes Simplex Virus Pathogenesis By Irf-3, And Irf-7 Revealed Through Non-invasive Bioluminescence Imaging

Intrinsic innate immunity fails to control herpes simplex virus and vesicular stomatitis virus replication in sensory neurons and fibroblasts. J Virol 2014 Sep 1; Synergistic control of herpes simplex virus pathogenesis by IRF-3, and IRF-7 revealed through non-invasive bioluminescence imaging. In addition to controlling viral replication, IRF-3 and -7 therefore play coordinating roles in modulation of inflammation during HSV infection. Herpes simples virus type 1 and 2 (HSV-1 and HSV- 2) and Varicella- zoster virus (VSV) are members of this subfamily. These three viruses produce vesicular rashes both in their primary infections and in reactivation. III. VIRAL STRUCTURE AND OVERVIEW OF VIRAL REPLICATION A. F. Treatment and Control. 1. HSV has been an object of interest into research and development as a treatment vector for cancer. HSV has many traits that make it desirable as a treatment vector; HSV can infect a wide variety of cell types, the normal replication cycle of HSV causes cells to lyse (killing cancerous cells) , The HSV genome has many genes that are non-essential to replication that can be replaced with therapeutic genes, there are already many pharmaceutical options that can be used to control against unwanted replication of the virus, and the viral genome remains as an intact plasmid within the cell nucleus which protects against unwanted insertion of viral DNA into the host genome (Varghese, 2002). Herpes Simplex Virus (HSV) Stromal Keratitis and Endotheliitis Disease. HSV infection of the mucosal and epithelial surfaces of the orofacial region, including the cornea, precedes retrograde axonal transport of the virus within the respective division of the trigeminal nerve to the trigeminal ganglia, where additional viral replication occurs and latency is established within neuronal nuclei. CD8+ T cell control of latent herpes simplex virus type 1 infections. Herpes simplex virus type 1 (HSV-1) represents a viral vector system with several biological features that make it attractive for gene delivery to the peripheral or visceral nervous system (10, 11). In brief, the murine -NGF cDNA fused to the SV40 late polyA signal was juxtaposed downstream of the HSV-1 LAP2 promoter (21) in a plasmid that contains the lacZ gene cassette under the control of the HSV-1 glycoprotein C late gene promoter. In contrast, HSV UL49 is not required for viral replication in culture whereas its VZV homolog (encoded by ORF9) is essential to VZV growth 22. Moreover, CD8+T cells can block HSV-1 reactivation from latency in mice and appear to play a major role in control of HSV-2 in the human genital tract 59. 13 In addition, acyclovir-resistant strains of herpes simplex virus (HSV) are beginning to emerge, further emphasizing the need for new antiviral lines of defense in combating HK. HTCEpi monolayers that had been exposed to DBD plasmatreated medium contained significantly lower HSV-1 genome copies than control monolayers. DBD plasmatreated medium reduces viral replication in human corneal epithelial cells.
