Gammaherpesvirinae
''Gammaherpesvirinae'' is a subfamily of viruses in the order ''Herpesvirales'' and in the family ''Herpesviridae''. Viruses in ''Gammaherpesvirinae'' are distinguished by reproducing at a more variable rate than other subfamilies of ''Herpesviridae''. Mammals serve as natural hosts. Viruses associated with disease in this subfamily include Epstein–Barr virus and Kaposi's sarcoma-associated herpesvirus. Taxonomy Herpesviruses represent a group of double-stranded DNA viruses distributed widely within the animal kingdom. The family ''Herpesviridae'', which contains eight viruses that infect humans, is the most extensively studied group within this order and comprises three subfamilies, namely ''Alphaherpesvirinae'', ''Betaherpesvirinae'' and ''Gammaherpesvirinae''. Genera ''Gammaherpesvirinae'' consists of the following seven genera: * '' Bossavirus'' * '' Lymphocryptovirus'' * ''Macavirus'' * '' Manticavirus'' * '' Patagivirus'' * '' Percavirus'' * '' Rhadinovirus'' Str ...

Kaposi's Sarcoma-associated Herpesvirus
Kaposi's sarcoma-associated herpesvirus (KSHV) is the ninth known human herpesvirus. It is also called Human herpesvirus 8, or HHV-8 in short. This virus causes Kaposi's sarcoma, a cancer commonly occurring in AIDS patients, as well as primary effusion lymphoma, HHV-8-associated multicentric Castleman's disease and KSHV inflammatory cytokine syndrome. It is one of seven currently known human cancer viruses, or oncoviruses. Even after many years since the discovery of KSHV/HHV8, there is no known cure for KSHV associated tumorigenesis. History In 1872, Moritz Kaposi described a blood vessel tumor (originally called "idiopathic multiple pigmented sarcoma of the skin") that has since been eponymously named Kaposi's sarcoma (KS). KS was at first thought to be an uncommon tumor of Jewish and Mediterranean populations until it was later determined to be extremely common throughout sub-Saharan African populations. This led to the first suggestions in the 1950s that this tumor mig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Epstein–Barr Virus
The Epstein–Barr virus (EBV), also known as human herpesvirus 4 (HHV-4), is one of the nine known Herpesviridae#Human herpesvirus types, human herpesvirus types in the Herpesviridae, herpes family, and is one of the most common viruses in humans. EBV is a DNA virus#Double-stranded DNA viruses, double-stranded DNA virus. EBV is the first identified oncogenic virus, a virus that can cause cancer. EBV establishes permanent infection in human B cells. It uncommonly causes infectious mononucleosis and is also tightly linked to many Malignancy, malignant diseases (cancers and autoimmune diseases). Various vaccine formulations have been tested in animals and humans; however, none of them were able to prevent EBV infection, thus, no vaccine has been approved to date. Infectious mononucleosis ("mono" or "glandular fever"), is characterized by extreme fatigue, fever, sore throat, and swollen lymph nodes. EBV is also associated with various non-malignant, premalignant, and malignant E ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Herpesviridae
''Orthoherpesviridae'', previously named and more widely known as ''Herpesviridae'', is a large family of DNA viruses that cause infections and certain diseases in animals, including humans. The members of this family are commonly known as herpesviruses. The family name is derived from the Greek word ἕρπειν ( 'to creep'), referring to spreading cutaneous lesions, usually involving blisters, seen in flares of herpes simplex 1, herpes simplex 2 and herpes zoster ( shingles). In 1971, the International Committee on the Taxonomy of Viruses (ICTV) established ''Herpesvirus'' as a genus with 23 viruses among four groups. Since then, the number of identified herpesviruses has grown to more than 100. Herpesviruses can cause both latent and lytic infections. Nine herpesvirus types are known to primarily infect humans, at least five of which are extremely widespread among most human populations, and which cause common diseases: herpes simplex 1 and 2 (HSV-1 and HSV-2, also know ...

Herpesvirales
''Herpesvirales'' is an order of dsDNA viruses (Baltimore group I) with animal hosts, characterised by a common morphology consisting of an icosahedral capsid enclosed in a glycoprotein-containing lipid envelope. Common infections in humans caused by members of this order include cold sores, genital herpes, chickenpox, shingles, and glandular fever. ''Herpesvirales'' is the sole order in the class ''Herviviricetes'', which is the sole class in the phylum ''Peploviricota''. Virology Morphology All members of the order have a virion structure that consists of a DNA core surrounded by an icosahedral capsid composed of 12 pentavalent and 150 hexavalent capsomeres (T = 16). The capsid has a diameter of ~110 nanometers (nm) and is embedded in a proteinaceous matrix called the tegument, which in its turn is enclosed by a glycoprotein-containing lipid envelope with a diameter of about 200 nm. The DNA genome is linear and double stranded, with sizes in the range 125–290 kbp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
