Gene transfer used to deliver antibodies to fight Anthrax

Using gene transfer technology, investigators were able to immunize mice against anthrax in just 12 hours, according to new research featured in the February 2005 issue of Molecular Therapy, the peer-reviewed scientific journal of the American Society of Gene Therapy (ASGT).

Screening for malaria necessary for U.S. soldiers returning from Afghanistan

Nearly 40 U.S. Army Rangers returning from Afghanistan in 2002 may have contracted malaria because of inadequate use of preventive measures, according to a study in the January 12 issue of JAMA.

Core promoter mutants of Hepatitis B Virus e Antigen associated with development of fulminant hepatitis and liver cancer

Scientists in Brown Medical School, Providence, USA, have found that core promoter mutants of Hepatitis B Virus e Antigen replicate at up to 10-fold higher levels in transfected human hepatoma cells than the wild-type virus.

Evidence suggests that changes in the bacteria and fungi in the gastrointestinal tract can intensify the immune system's reaction to common allergens

If you want to avoid allergies or asthma, scientists at the University of Michigan Medical School suggest you start paying more attention to what's in your gut.

Study models impact of anthrax vaccine

Rapidly distributing antibiotics to people exposed to anthrax spores during a bioterrorist attack, could by itself, prevent about 70 percent of anthrax infections from occurring, according to researchers from the Johns Hopkins Bloomberg School of Public Health.

Start today of human tests for a preventive vaccine against the respiratory disease SARS

Powerful research tools that speed up vaccine development have led to the start today of human tests for a preventive vaccine against the respiratory disease SARS. The disease killed hundreds of people around the world before it was brought under control in 2003 with aggressive conventional public health measures.

Key molecular signal allows malarial parasites to target human red blood cells

Northwestern University researchers have identified a key molecular "signal" that allows malarial parasites to release virulence proteins inside human red blood cells.

First live imaging of specialized immune system cells reveals new clues about body’s security system

To keep the body safe, the immune system enlists more than one form of protection. A circulating task force of immune system cells monitors the body’s periphery, and sends information back to field command centers — the lymph nodes — located at pivotal traffic points.

Potential vaccine for the deadly toxin ricin

A potential vaccine for the deadly toxin ricin, a "Category B" biological agent, will enter the first phase of clinical testing in coming weeks at UT Southwestern Medical Center at Dallas.

Citrus fruits offer promise in fighting childhood cancer

Orange juice and cancer don't mix. In fact, the popular citrus drink could become a cocktail to prevent or stop the deadly disease in humans.

Stress affects molecules believed to play a key role in cellular aging

There have been many studies that have shown that your health is greatly affected by how you react to stressful events in life-setbacks or deadlines at work, conflicts and losses at home.

Salmonella pathogen uses molecular hydrogen to grow and become virulent

New research, headed by microbiologists from the University of Georgia, show for the first time that Salmonella – a widespread and often deadly bacterial pathogen – use molecular hydrogen to grow and become virulent.

New research may lead to treatments for atherosclerosis

Scientists are one step closer to deciphering the molecular signaling process controlling innate immunity with the discovery that a molecule called IRAK1 regulates the expression of the anti-inflammatory cytokine IL-10. Because atherosclerosis patients often have elevated IL-10 levels, IRAK1 may be a viable target for developing therapeutics for atherosclerosis.

Asthma study looks at genetic variation and influence response to microbial exposure

The "hygiene hypothesis" suggests that exposures to microbes early in life may drive immune system development in a way that reduces a person's susceptibility to asthma and other allergic diseases.

Researchers recommend vaccinating adolescents against whooping cough

Experts are recommending that adolescents and some adults be vaccinated against whooping cough to help prevent infection and potential transmission to infants, according to the December 15 issue of Clinical Infectious Diseases, now available online.

Answer to the increase of flu cases may be extremely minute seasonal changes

Flu season is on its way to homes across Canada. But the question of why influenza epidemics take place in the few cold months of winter remains unanswered. Is it the change in the weather? The return to school? Or increased viral production under winter conditions?

Hong Kong launches flu vaccination programme

To prevent the spread of flu in the coming peak season, it is important that the public and private sectors work together to provide influenza vaccinations to members of the public.

Testosterone may impede immunity

Decreasing testosterone boosts immunity because testosterone helps control T-lymphocytes, the attack cells of the immune system, according to Mayo Clinic-led research in laboratory animals.

VaxGen gets $877.5 million to supply 75 million doses of anthrax vaccine

VaxGen announced today that the U.S. government has awarded the company an $877.5 million contract to supply 75 million doses of anthrax vaccine for civilian defense.

Researchers investigate new treatment options, including ways to boost immune responses to better control HIV

Highly active antiretroviral therapy (HAART) for the treatment of individuals infected by HIV-1 is limited by high costs, drug resistance, and drug-related toxicities. This has led researchers to investigate new treatment options, including ways to boost immune responses to better control HIV.
