Cell Biology Of Herpes Viruses

Herpes viruses are widely distributed in nature, causing disease in organisms as diverse as bivalves and primates, including humans. Each virus appears to have established a long-standing relationship with its host, and the viruses have the ability to manipulate and control the metabolism of host cells, as well as innate and adaptive antiviral immune responses. Herpes viruses maintain themselves within hosts in a latent state resulting in virus persistence for years – usually for the life span of the hosts. Herpes viruses comprise a large number of pathogens with diverse cellular targets and biological consequences of infection. What they have in common is their structure and the fact that they establish a dormant (latent) infection in their hosts that usually persists for life. The reviews here will highlight the general principles of herpes virus infection, with equal attention to overall principle and important difference. Also, the cell type- and life-style dependent differences in the establishment and maintenance of virus persistence will be covered.

This comprehensive account of the human herpesviruses provides an encyclopedic overview of their basic virology and clinical manifestations. This group of viruses includes human simplex type 1 and 2, Epstein–Barr virus, Kaposi's Sarcoma-associated herpesvirus, cytomegalovirus, HHV6A, 6B and 7, and varicella-zoster virus. The viral diseases and cancers they cause are significant and often recurrent. Their prevalence in the developed world accounts for a major burden of disease, and as a result there is a great deal of research into the pathophysiology of infection and immunobiology. Another important area covered within this volume concerns antiviral therapy and the development of vaccines. All these aspects are covered in depth, both scientifically and in terms of clinical guidelines for patient care. The text is illustrated generously throughout and is fully referenced to the latest research and developments.

The alpha herpesviruses are an important group of viruses characterized by a short reproductive cycle, rapid destruction of the host cell, and the ability to replicate in a wide variety of host tissues. A key attribute of these viruses is the ability to establish lifelong latent infection in the peripheral nervous system of the natural host. Research into the molecular and cellular biology of the alpha herpesviruses has advanced greatly in recent years. Written by internationally recognized experts, this book highlights the more provocative and exciting findings in herpesvirus research. Each chapter is a review of a specific area with an emphasis on recent advances and the latest developments. The book examines multifunctional proteins, advances in DNA replication, new information on the regulation of gene expression, the emergence of new technologies, recent technological advances in fluorescent probes, the induction of apoptosis, the disruption of interferon, vaccine development, and drug design. With a specific focus on new and topical herpesvirus research, Alpha Herpesviruses is essential reading for everyone with an interest in herpesviruses and it is recommended reading for other scientists working in viral pathogenesis, viral genomics, and antiviral research.

Six members of the Herpesviridae family are human pathogens, including herpes and 2 (HSV-I and 2), Epstein-Barr virus (EBV), varicella zoster simplex virus I virus (VZV), human cytomegalovirus (HCMV), and human herpesvirus 6 (HHV 6). Each of these viruses is capable of causing distinct diseases of varying severity in children, young adults, and the aged. The diseases range from infection of epithelial tissue to the infection of internal organs and white blood cells. A common feature of the six pathogenic human herpesviruses is their ability to latently infect different cell types in which the viral DNA is not integrated and is unable to express its pathogenicity. Reactivation of the herpesviruses is a result of cellular processes which reactivate viral genes, leading to virus progeny and to signs of infection. Due to their ability to become latent after initial infection, once the pathogenic herpesviruses infect children they are maintained throughout life, having the potential of cause various diseases upon reactivation.

Alphaherpesviruses are a fascinating group of DNA viruses that includes important human pathogens such as herpes simplex virus type 1 (HSV-1), HSV-2, and varicella-zoster virus (VZV): the causative agents of cold sores, genital ulcerous disease, and chickenpox/shingles, respectively. A key attribute of these viruses is their ability to establish lifelong latent infection in the peripheral nervous system of the host. Such persistence requires subversion of the host's immune system and intrinsic antiviral defense mechanisms. Understanding the mechanisms of the immune evasion and what triggers viral reactivation is a major challenge for today's researchers. This has prompted enormous research efforts into understanding the molecular and cellular biology of these viruses. This up-to-date and comprehensive volume aims to distill the most important research in this area providing a timely overview of the field. Topics covered include: transcriptional regulation, DNA replication, translational control, virus entry and capsid assembly, the role of microRNAs in infection and oncolytic vectors for cancer therapy. In addition there is coverage of virus-host interactions, including apoptosis, subversion of host protein quality control and DNA damage response pathways, autophagy, establishment and reactivation from latency, interferon responses, immunity and vaccine development. Essential reading for everyone working with alphaherpesviruses and of interest to all virologists working on latent infections.
