AP/Washington Post examines experimental malaria vaccine, mutant mosquitoes to combat malaria

During the 1990s, Sanaria CEO Stephen Hoffman "irradiated malaria-carrying mosquitoes to weaken the parasites inside them, and he and 13 colleagues subjected themselves to more than 1,000 bites," according to the AP/Washington Post.

Cancer vaccine efficacy enhanced using anti-diabetic drug Metformin

After a vaccination or an infection, the human immune system remembers to keep protecting against invaders it has already encountered, with the aid of specialized B-cells and T-cells. Immunological memory has long been the subject of intense study, but the underlying cellular mechanisms regulating the generation and persistence of long-lived memory T cells remain largely undefined. Now, University of Pennsylvania School of Medicine researchers have found that a common anti-diabetic drug might enhance the effectiveness of vaccines. The findings are described this week in an advanced online publication of Nature.

Metformin may 'revolutionize' cancer-fighting treatments

Researchers at McGill University and the University of Pennsylvania have discovered that a widely used anti-diabetic drug can boost the immune system and increase the potency of vaccines and cancer treatments. Their findings will be published June 3 in the journal Nature.

Discovery of new arenavirus associated with hemorrhagic fever – first identified in nearly four decades

Scientists at Columbia University's Mailman School of Public Health, the South African National Institute for Communicable Diseases of National Health Laboratory Service (NICD-NHLS), the U.S. Centers for Disease Control and Prevention, and Roche's 454 Life Sciences Corporation have discovered the new virus responsible for a highly fatal hemorrhagic fever outbreak in Zambia and South Africa in late 2008.

Experts say let swine flu run its course

With the number of influenza A H1N1 (swine flu) cases in Australia now over 300 federal Health Minister Nicola Roxon says the government is considering whether to elevate the nation's response to the disease from the contain to sustain phase, as it may be impossible to keep quarantining people.

Australian scientist finds two new animal viruses

An Australian scientist has discovered two new animal viruses, one in cattle and the other in mosquitoes - the unknown viruses were found in isolated regions of northern Australia - neither of the viruses cause disease in livestock.

ImmunoVaccine Technologies partners with FIT Biotech to advance therapeutic HIV vaccine

ImmunoVaccine Technologies Inc. (IVT), a Canadian vaccine development company, announced a research partnership with FIT Biotech, a Finland-based , clinical stage company that develops DNA vaccines. This research will formulate FIT Biotech's GTU MultiHIV DNA plasmid with IVT's DepoVax vaccine delivery system to advance a therapeutic HIV vaccine.

Tuberculosis can evade immune response

Current research suggests that Mycobacterium tuberculosis can evade the immune response. The related report by Rahman et al, "Compartmentalization of immune responses in human tuberculosis: few CD8+ effector T cells but elevated levels of FoxP3+ regulatory T cells in the granulomatous lesions," appears in the June 2009 issue of The American Journal of Pathology.

Recommendations by experts to WHO on influenza A (H1N1) vaccines

Current epidemiological information suggests that the influenza A (H1N1) virus transmissibility potential is at least comparable to that of seasonal influenza viruses, with ability to sustain community spread. There is therefore no reason to expect that ongoing spread of the virus will stop.

Experts warn of dangers of swine flu with almost 10,000 now infected, forecasts 4.9 billion doses needed

The latest figures from the World Health Organisation (WHO) has the worldwide influenza A H1N1 (swine flu) tally fast approaching 10,000 human cases.

Discovery of new target in fight against osteoporosis, periodontitis

Osteoporosis and periodontitis are common diseases whose sufferers must cope with weakness, injury and reduced function as they lose bone more quickly than it is formed. While the mechanism of bone destruction in these diseases is understood, scientists have had less information about how bone formation is impaired.

Computer simulation captures immune response to flu

Researchers have successfully tested first the first time a computer simulation of major portions of the body's immune reaction to influenza type A, with implications for treatment design and preparation ahead of future pandemics, according to work accepted for publication, and posted online, by the Journal of Virology.

Chronic infection clearly linked to key immunity protein

The reason deadly infections like human immunodeficiency virus (HIV) and hepatitis C never go away is because these viruses disarm the body's defense system.

Baylor Research Institute receives multi-million dollar grant to develop flu vaccine

Scientists at Baylor Institute for Immunology Research (BIIR) in Dallas, part of Baylor Research Institute (BRI) and the Baylor Health Care System, announced today that they received a renewal of a multi-million dollar grant from the National Institutes of Health (NIH) to design new vaccines to prevent influenza - including swine flu (H1N1).

New mathematical model predicts immune response to influenza A virus

Researchers at the University of Rochester have developed a mathematical model to predict immune responses to infection with influenza A viruses, including novel viruses such as the emergent 2009 influenza A (H1N1). This model examines the contributions of specific sets of immune cells in fighting influenza A virus.
