Epstein-Barr virus protein crucial to its role in blood cancers

Researchers at the University of Pennsylvania School of Medicine have identified a link between a critical cancer pathway and an Epstein-Barr Virus (EBV) protein known to be expressed in a number of EBV-associated cancers. Their findings demonstrate a new mechanism by which EBV transforms human B cells from the immune system into cancerous cells, which can lead to development of B-cell lymphomas....

U of T researchers map role of Epstein-Barr virus in cancer

Researchers at the University of Toronto have mapped the molecular details that show how a viral protein coded in the Epstein-Barr virus immortalizes cells and causes them to continuously grow, thereby predisposing people to certain types of cancer. . "Epstein-Barr virus (EBV) is one of the most common human viruses in the world and is strongly linked to certain b-cell cancers like Burkitt's lymp...

Specialized immune-system B cells play double-barreled role

A specialized subpopulation of the antibody-producing B cells of the immune system plays a "double-barreled" role in triggering both kinds of immunity -- innate and acquired, Duke University Medical Center immunologists have discovered. The division of labor between B-1a and B-1b cells they have uncovered offers basic insights that could contribute to more rational development of vaccines, they s...

Slipping past the blood brain barrier: Research shows potential treatment for brain cancer

A compound that kills cancer can sneak past the blood brain barrier, which protects the brain from foreign substances, to do its work in fighting a particularly invasive brain cancer, according to a new Saint Louis University animal study published in the Proceedings of the National Academy of Sciences Online Early Edition the week of Aug. 22. . "The bottom line is, if you can get drugs into the...

Primate virus jumps species barrier to humans for first time in Asia

Scientists have identified the first reported case in Asia of primate-to-human transmission of simian foamy virus (SFV), a retrovirus found in macaques and other primates that so far has not been shown to cause disease in humans. The transmission of the virus from a monkey to a human took place at a monkey temple in Bali, Indonesia, the researchers report in the July issue of the journal Emerging...

Divergent mating systems and parental conflict as a barrier to hybridization in flowering plants

Sexual reproduction can be thought of as a cooperative process in which two individuals come together to produce a new individual. It can also be viewed as a process in which two parties with differing interests, investment, and background interact to produce a new individual. From the former perspective, parental interests are unified (both wish to produce vigorous offspring), while the latter s...

Mechanism for Epstein-Barr virus protein's role in blood cancers discovered

Earlier this year, researchers at the University of Pennsylvania School of Medicine identified a link between a critical cancer pathway and an Epstein-Barr Virus (EBV) protein known to be expressed in a number of EBV-associated cancers. Their findings demonstrated a new mechanism by which EBV can transform human B cells from the immune system into cancerous cells, which can lead to B-cell lymphom...

Cell barrier shows why bird flu not so easily spread among humans

Although more than 100 people have been infected with the H5N1 avian influenza virus, mostly from close contact with infected poultry, the fact that the virus does not spread easily from its pioneering human hosts to other humans has been a biomedical puzzle. . .. The finding, reported today (March 23, 2006) in the journal Nature, is important because it demonstrates a requisite characteristic fo...

Epstein-Barr virus may be associated with multiple sclerosis

Young adults with high levels of antibodies against the Epstein-Barr virus, the virus that most often causes mononucleosis, may be more likely to develop multiple sclerosis 15 to 20 years later, according to a study posted online today that will appear in the June 2006 print issue of Archives of Neurology, one of the JAMA/Archives journals. . Researchers have long suspected that external factors...

Epstein-Barr virus might kick-start multiple sclerosis

Researchers have found that patients with multiple sclerosis (MS) carry a population of immune cells that overreact to Epstein-Barr virus. The virus, which causes mononucleosis and may contribute to some cancers, has long been suspected to play a role in MS. However, the mechanism linking the virus to the disease was poorly understood. . Scientists think that MS--which can cause vision problems,...

Clue found to Epstein-Barr virus' ability to form and sustain tumors

Researchers at the University of Wisconsin School of Medicine and Public Health (SMPH) have found a viral target that opens the door for the development of drugs to destroy tumors caused by Epstein-Barr virus (EBV). . .. Often linked to infectious mononucleosis, EBV also causes cancers that kill...

CSIRO imagery shows Outer Great Barrier Reef at risk from river plumes

A stunning series of satellite imagery of Australia's Great Barrier Reef released by the CSIRO shows for the first time visual confirmation of the theory that sediment plumes travel to the outer reef, and beyond. . .. Images captured by CSIRO show large plumes of t...

Blood-brain barrier breached by new therapeutic strategy

A major obstacle in the treatment of infections and other diseases of the brain is the blood-brain barrier, which prevents systemically delivered therapeutic drugs from reaching the brain. Grantees of the National Institute of Allergy and Infectious Diseases, part of the National Institutes of Health, have now shown that a short protein (peptide) from the rabies virus can carry a strip of therap...
