NYU Study Reveals How Brain's Immune System Fights Viral Encephalitis

...e West Nile virus has been responsible for a viral encephalitis outbreak in the northeast. The NYU researchers set...d. The researchers attributed the spread of viral encephalitis to the inability of lab mice to produce sufficient amounts of interferons to fight the virus. ...

Antibiotic might fight HIV-induced neurological problems

...treated monkeys had evidence of moderate or severe encephalitis and much more physical evidence of damage to brain cells, the researchers report. "The infection in the animal model is predictable and aggressive, so we can get meaningful data by studying fewer animals," says Zink, who was on the team that develop...

A new study examines how shared pathogens affect host populations

... pathogens like malaria, Lyme disease or West Nile encephalitis that infect multiple hosts are commonly transmitted by vectors, and their transmission rate is often thought to depend on the proportion of hosts or vectors infected (i.e. frequency dependence). A study, to appear in the July 2005 issue of The Americ...

NIAID begins clinical trial of West Nile virus vaccine

...nfections of the brain and nervous system, such as encephalitis or meningitis. In 2004, 2,470 cases of WNV disease were reported in the United States, resulting in 88 deaths. Currently, no WNV vaccine is licensed for use in humans. The experimental vaccine is composed of a small, circular piece of DNA--called a ...

Discovery could be key to bioterrorism defense

...itially isolated in 1999, when a large outbreak of encephalitis and respiratory illness occurred in Malaysia and Singapore, killing more than 100 people. Last year, two further Nipah virus outbreaks occurred in Bangladesh, killing roughly 75% of those infected. Scientists are disturbed by the fact that many of th...

Scientists show that tick-borne flaviviruses use a novel mechanism to evade host defenses

...rus, yellow fever virus, dengue virus and Japanese encephalitis virus; the less-familiar tick-borne flaviviruses are just as serious, causing tick-borne encephalitis or hemorrhagic fevers. Currently, a Japanese encephalitis outbreak is raging in India and Nepal and ...

New NIAID grants strengthen national biodefense and emerging infectious diseases research network

...rchers in the new centers have expertise in equine encephalitis and other viral diseases that can be transmitted to people by mosquitoes. The centers also add expertise in hantaviruses, as well as in the development of diagnostics and animal models of disease. Each consortium within the network will * suppo...

Serious adverse reactions to smallpox vaccine appear to be limited

...action to vaccination) and 1 case of postvaccinial encephalitis (inflammation of the brain) were detected. No preventable life-threatening adverse reactions, contact transmissions, or adverse reactions that required treatment with vaccinia immune globulin were identified. Serious adverse events were more common a...

Ocean virus identified in human blood samples

...r damage or some other problems, which may include encephalitis and spontaneous abortion. The viral group being studied is the genus Vesivirus, one of four genera in the Caliciviridae viral family. Some caliciviruses cause disease in humans, such as the Norwalk virus that causes gastroenteritis. Other caliciviru...

Genetic mutation linked to West Nile virus infection

...to-borne virus that caused a1999 outbreak of fatal encephalitis in the US -- was uniformly fatal in mice that lack CCR5. This finding prompted Murphy and his colleagues to look for the CCR5delta32 mutation in patients in the US who were diagnosed with WNV infections. They now report that individuals with two co...

Hopkins study suggests commercially available antibiotic may help fight dementia in HIV patients

...heimer's, and infections of the brain, like herpes encephalitis and West Nile encephalitis," says Rumbaugh. "However, it will require a lot more development before drugs like these can be used even to treat patients with HIV dementia, let alone to treat patients with other neurological diseases." ...

Einstein researchers demonstrate a novel approach to treating AIDS

...ccus neoformans, which can cause life-threatening encephalitis in AIDS patients and other people with weakened immune systems; then a streptococcal bacterium responsible for pneumonia; and now HIV. The researchers zapped the fungi and bacteria directly, but, in the case of HIV, they aimed for the immune cells th...

Blood-brain barrier breached by new therapeutic strategy

...protect mice from infection caused by the Japanese encephalitis virus (JEV). Manjunath N. Swamy, M.D., of the CBR Institute for Biomedical Research and Harvard Medical School in Boston, and his colleagues used JEV to infect the brains of mice. They then injected the antiviral siRNA bound to the rabies peptide t...

Brain inflammation may be friend, not foe, for Alzheimer's patients

...ht with difficulty, producing side effects such as encephalitis or severe brain inflammation in people with Alzheimer’s. “The potential to treat Alzheimer’s disease by modulating the immune system is tremendous and is an area that has not been fully explored,” said O’Banion. “That said, people have to remember...
