Herpes simplex virus 1 and 2 (HSV-1 and HSV-2) are two strains of the herpes virus family, Herpesviridae, which cause extremely painful infections in humans.[1] They are also called Human Herpes Virus 1 and 2 (HHV-1 and HHV-2).
An infection is marked by watery blisters in the skin or mucous membranes (such as the mouth or lips) or on the genitals.[1] Lesions heal with a scab characteristic of herpetic disease. HSV is transmitted by contact with lips or genitals when the sores are present, or possibly when sores are not visible (known as viral shedding).
The genomes of HSV-1 and HSV-2 are complex, and contain two unique regions called the long unique region (UL) and the short unique region (US).
Entry of HSV into the host cell involves interactions of several glycoproteins on the surface of the enveloped virus, with receptors on the surface of the host cell. In the case of a herpes virus, initial interactions occur when a viral envelope glycoprotein called glycoprotein C (gC) binds to a cell surface particle called heparan sulfate.
After the viral capsid enters the cellular cytoplasm, it is transported to the cell nucleus. Consequent to a cell being infected, groups of Herpes virus proteins, termed immediate-early, early, and late proteins, are produced following specific time periods. The early proteins transcribed are used in the regulation of genetic replication of the virus. The late proteins transcribed are used in the capsid formation and forming the receptors on the surface of the virus. HSV may persist in a quiescent but persistent form known as latent infection, notably in neural ganglia.[1] During latent infection of a cell, HSV express Latency Associated Transcript (LAT) RNA. The virus can be reactivated due to the effects of other illnesses such as cold and influenza, excema, menstruation, emotional and physical stress, exposure to bright sunlight, gastric upset, fatigue or injury, consequently resulting in the appearance of surface sores.
Note (2): Treatment for 21 days for disseminated disease and that involving the central nervous system. Alternative Regimen (2): Imiquimod topical preparations should be applied to the lesions qd for 5 consecutive days.


Note:The sex partners of persons who have genital herpes can benefit from evaluation and counseling.
Allergic and other adverse reactions to oral Acyclovir, Valacyclovir, and Famciclovir are rare. Fusion with the plasma membrane to release the core and the tegument proteins into the host cytoplasm. The capsid is transported to the nuclear pore where viral DNA is released into the nucleus. Transcription of immediate early genes which promote transcription of early genes and protect the virus against innate host immunity. Transcription of early viral mRNA by host polymerase II, encoding proteins involved in replication of the viral DNA. Assembly of the virus in nuclear viral factories and budding through the inner lamella of the nuclear membrane which has been modified by the insertion of herpes glycoproteins, throughout the Golgi and final release at the plasma membrane.
Latent replication : replication of circular viral episome in tandem with the host cell DNA using the host cell replication machinery. Herpes simplex protein US12 binds specifically to transporters associated with antigen processing (TAP), blocking peptide-binding to TAP and subsequent loading of peptides onto MHC class I molecules .
Herpes simplex virus 1 glycoprotein B and US3 collaborate to inhibit CD1d antigen presentation and NKT cell function . Herpes simplex virus ICP34.5 confers neurovirulence by targeting the Beclin 1 autophagy protein and thus blocking host autophagy process . The viral proteins ICP27 and vhs act jointly to repress host gene transcription and blocks the cell cycle at the G1 phase . Herpes simplex virus inhibits the cascade leading to production of interferon-beta by targeting different cellular proteins.
HSV vector-mediated transgene expression in rat L6-S1 DRGs after administration of vector to the bladder wall. However, the infection is persistent and symptoms may recur periodically as outbreaks of sores near the site of original infection. The structure of herpes viruses consists of a relatively large double-stranded, linear DNA genome encased within an icosahedral protein cage called the capsid, which is wrapped in a lipid bilayer called the envelope.


The envelope covering the virus particle, when bound to specific receptors on the cell surface, will fuse with the host cell membrane and create an opening, or pore, through which the virus enters the host cell.
Once attached to the nucleus at a nuclear entry pore, the capsid ejects its DNA contents via the capsid portal. On entering the cell, an ?-TIF protein joins the viral particle and aids in immediate-early Transcription.
These drugs are activated by the viral specific enzyme, thymidine kinase, and are therefore specific to herpes-infected cells. It has been shown to act as a splicing silencer at the 3’ splice site of the PML intron 7a .
There are three temporal classes of genes: immediate-early (alpha), early (beta) and late (gamma). These drugs act against the replicating virus (they are incorporated into the DNA as it is copied) and are ineffective against a latent virus. Additionally, it also interacts with programmed cell death protein 4 (PDCD4) and retains it in the nucleus thereby inhibiting host apoptosis .
A significant number of GFP-positive cells were seen in L6-S1 DRG 3 weeks after HSV-GAD treatment.
The immediate-early genes are transcribed immediately after infection to take control of cell defense and to activate early genes. The HSV-GAD-treated rats with SCI show increased GAD67-like immunoreactivity in L6-S1 DRG neurons of small and medium sizes compared with the HSV-LacZ-treated rat with SCI.
Certain proteins are downregulated translationaly by a leaky scanning from an upstream ORF.
