Herpes simplex virus replication: roles of viral proteins

  1. Replication of herpes simplex virus type 1 (HSV-1) involves a step in which a parental capsid docks onto a host nuclear pore complex (NPC). The viral genome then translocates through the nuclear pore into the nucleoplasm, where it is transcribed and replicated to propagate infection
  2. This work will focus primarily on DNA replication of herpes simplex virus 1 and 2 (HSV-1 and HSV-2), but will refer, on occasion, to findings from other herpesviruses. Because this work is intended to update the work on HSV DNA replication written for the previous edition of DNA Replication and Human Disease ( Weller and Coen 2006 ), it draws primarily from work published during the last 6 years

  4. It is our intention to provide an up-to-date analysis of our understanding of the structures of these replication proteins and how they function during HSV replication. The potential roles of host repair and recombination proteins will also be discussed

Herpesviruses are divided into three groups: The α herpesviruses, herpes simplex virus types 1 and 2, and varicella-zoster virus, have a short replicative cycle, induce cytopathology in monolayer cell cultures, and have a broad host range; β herpesviruses, cytomegalovirus, and huma Herpes virus replication i) Binding to the cell surface: As with many other viruses, cell tropism is determined by the availability of the correct receptor on the surface of the cell to be infected

Herpes simplex virus (HSV) replicated in mitogen-stimulated human T cells. Virus replication was obtained in highly enriched mitogen-stimulated T cells of the OKT 3+, OKT 4+, or OKT 8+ subtype, in stimulated B cells, and in macrophages precultured for 7 days The virion host shutoff protein (VHS or UL41) is very important to viral replication. This enzyme shuts off protein synthesis in the host, degrades host mRNA, helps in viral replication, and regulates gene expression of viral proteins. The viral genome immediately travels to the nucleus, but the VHS protein remains in the cytoplasm Steps in Viral Replication: Assembly and Release (Sixth and Seventh Steps) Process involves bringing together newly formed genomic nucleic acid and structural proteins to form the nucleocapsid of the virus Nonenveloped viruses exhibit full maturation in the cytoplasm or nucleus with disintegration of cel Here we showed that honokiol had no effect on herpes simplex virus-1 (HSV-1) entry, but inhibited HSV-1 viral DNA replication, gene expression and the production of new progeny viruses. The combination of honokiol and clinical drug acyclovir augmented inhibition of HSV-1 infection Human peripheral blood leukocytes, lymphocyte subpopulations, and hemic cell lines were examined for their ability to supprot HSV and CMV replication. Mitogen-stimulated mononuclear leukocytes, B lymphocytes, and T lymphcytes supported the replication of HSV to high titers over 3 to 5 days of infection

The Herpesviridae comprise a large class of animal viruses of considerable public health importance. Of the Herpesviridae, replication of herpes simplex virus type-1 (HSV-1) has been the most extensively studied.The linear 152-kbp HSV-1 genome contains three origins of DNA replication and approximately 75 open-reading frames. Of these frames, seven encode proteins that are required for origin. Replication of herpes simplex virus takes place in the cell nucleus and is carried out by a replisome composed of six viral proteins:theUL30-UL42DNApolymerase,theUL5-UL8-UL52 helicase-primase, and the UL29 single-stranded DNA-binding protein ICP8. The replisome is loaded on origins of replication bytheUL9initiatororigin-bindingprotein. Herpes is a family of DNA viruses called Herpesviridae. The herpes family of viruses consists of three families of viruses; Alphaherpesviridae, Betaherpesviridae, and Gammaherpesviridae. Among these families are many commonly known viruses that are causative agents of many diseases, such as HSV-1 and HSV-2 for cold sores and genital warts.

HSV initiates rounds of DNA replication at one or all of the three origins of replication (Ori 1, Ori 2, and Ori 3). The initial step of HSV DNA replication is denaturation of the DNA at the replication origin with origin binding protein (UL9) Herpes simplex virus types 1 and 2 (HSV-1, -2) infect and also establish latency in neurons. In the present study, the authors investigated the influence of neuronal activity on the replication of HSV-1. The results showed that the sodium channel blocker tetrodotoxin (TTX) and the inhibitory neurotransmitter gamma-aminobutyric acid (GABA) could significantly increase viral replication in. Herpes family viruses are the leading cause of viral diseases in humans. There are at least 25 identified viruses in the family of Herpesviridae. They are very contagious and once infected remain in the human host for life. After infection, it retreats along nerve fibres to nerve cells near the brain or spinal cord, where it remains dormant

Herpes is one of the most common sexually transmitted diseases (STDs), prompting many to wonder how to get rid of herpes naturally. The herpes virus can live dormant inside a person's immune system for a lifetime, periodically causing blisters that burst and turn into open cold sores or ulcers before healing. When left alone, herpes cold sores usually last about 10-14 days and are. Replication of herpes simplex virus in WI-38 cells was inhibited by phosphonoacetic acid, as measured by decreased virus cytopathogenic effect and incorporation of radiolabeled thymidine in virus-infected cells. The drug appeared to have no effect on adsorption, penetration, or release of the virus nor on the synthesis of ribonucleic acid or protein. It appeared to inhibit virus. Genistein, an inhibitor of protein-tyrosine kinase, inhibited the replication of herpes simplex virus type 1 (HSV-1) at genistein concentrations of more than 25 µM, whereas the related compounds, which do not inhibit protein-tyrosine kinases, did not affect the replication of HSV-1. In the presence of genistein, the phosphorylation of tyrosine residues in specific viral polypeptides was.
