Avian flu research sheds light on swine flu outbreak

A new study by University of Maryland researchers suggests that the potential for an avian influenza virus to cause a human flu pandemic is greater than previously thought. Results also illustrate how the current swine flu outbreak likely came about.

New study overturns orthodoxy on how macrophages kill bacteria

For decades, microbiologists assumed that macrophages, immune cells that can engulf and poison bacteria and other pathogens, killed microbes by damaging their DNA.

Autoantibodies may be created in response to bacterial DNA

Autoimmune diseases have long been regarded as illnesses in which the immune system creates autoantibodies to attack the body itself. But today, researchers at the California non-profit Autoimmunity Research Foundation (ARF) explain that the antibodies observed in autoimmune disease actually result from alteration of human genes and gene products by hidden bacteria.

Test for best potential HIV/AIDS vaccine in the pipeline

Scientists in Britain are well on the way to developing a test for the best potential HIV/AIDS vaccine.

Australian researchers win bumper grant from Bill Gates for HIV research

Australian researchers have won themselves a bumper grant from the Bill & Melinda Gates Foundation to examine the best way of using drugs to treat HIV.

Scientists improve immune response to cancer

A team of scientists at The Campbell Family Institute for Breast Cancer Research (CFIBCR) at Princess Margaret Hospital and international collaborators have discovered how to trigger an improved immune response to cancer that could be included in new clinical trials that use a patient's own cells to destroy tumours.

Contamination of seeds for alfalfa sprouts linked to salmonella

The U.S. Food and Drug Administration (FDA) and the Centers for Disease Control and Prevention (CDC) have recommended that consumers not eat raw alfalfa sprouts, including sprout blends containing alfalfa sprouts, until further notice because the product has been linked to Salmonella serotype Saintpaul contamination.

Stem cells from adipose tissue offer hope for treatment of multiple sclerosis

A preliminary study on the use of stem cells obtained from a patient's own adipose tissue in the treatment of multiple sclerosis (MS) has shown promising results.

Immune cell type controls onset and course of severe malaria

Scientists have determined that a subset of immune cells may cause malaria patients to contract the severe form of the disease, suffering worse symptoms.

Proof-of-concept for a DNA-based therapeutic vaccination against chronic hepatitis C

The first-proof-of-concept for a DNA-based therapeutic vaccination against chronic hepatitis C was announced today at EASL 2009, the Annual Meeting of the European Association for the Study of the Liver in Copenhagen, Denmark.

Breakthrough in generating safer, therapeutic stem cells from adult cells

The new technique solves one of the most challenging safety hurdles associated with personalized stem cell-based medicine because for the first time it enables scientists to make stem cells in the laboratory from adult cells without genetically altering them.

Immune-boosting vaccine helps body fight cancer

Cancer Research UK-funded scientists have discovered that linking a molecule which initiates antibody production,to a 'saboteur' molecule, triggers the immune system to selectively destroy faulty cells. These findings published in Blood, could potentially be used to selectively destroy tumour cells while ignoring healthy cells.

Trial of unique malaria vaccine candidate to begin

In a move that highlights the strength of public-private collaboration in tackling international health challenges, the Maryland-based company Sanaria Inc., with support from the PATH Malaria Vaccine Initiative (MVI), has initiated a Phase 1 clinical trial - the first tests in adult volunteers - of its unique malaria vaccine candidate. Unlike other malaria vaccine candidates, Sanaria's approach deploys a weakened form of the whole malaria parasite harvested from irradiated mosquitoes instead of small portions of the parasite.

Discovery of molecule that could improve success of blood stem cell transplants

University of British Columbia researchers have discovered a "molecular key" that could help increase the success of blood stem cell transplants, a procedure currently used to treat diseases such as leukemia, Hodgkin's lymphoma and aplastic anemia.

Organic biosensor detects onset of acute myocardial ischemia

Engineering researchers at the University of Arkansas have fabricated and tested a unique biosensor that measures concentrations of potassium and hydrogen ions in the human heart with high specificity.

Lymphocytes promote cancer spread

Researchers at the UC San Diego School of Medicine and the Moores UCSD Cancer Center have new evidence that a type of immune system cell thought to be part of the first line of defense against breast cancer may also help promote its spread.

Double-lung transplants work better than single for long-term survival

Having both lungs replaced instead of just one is the single most important feature determining who lives longest after having a lung transplant, more than doubling an organ recipient's chances of extending their life by over a decade, a study by a team of transplant surgeons at Johns Hopkins shows.

Why an effective vaccine for HIV has proven so elusive

Some 25 years after the AIDS epidemic spawned a worldwide search for an effective vaccine against the human immunodeficiency virus (HIV), progress in the field seems to have effectively become stalled.

Engineered antibody gives cancer the recognition it deserves

In concept, the human immune system has the power to destroy cancer cells with great specificity.

New Dengue virus discovery could lead to development of anti-dengue drugs

Doctors have no specific drugs to treat dengue fever, a viral illness spread by mosquitoes that sickens 50 million to 100 million people worldwide each year. Instead, the only treatments they can recommend for this painful and sometimes fatal illness (20,000 deaths globally each year) are fluids, rest and non-aspirin pain and fever reducers.
