Unorthodox vaccine could one day help to prevent or control HIV infection

Researchers at Baylor College of Medicine (BCM) in Houston have reason to believe their unorthodox vaccine could one day help to prevent or control HIV infection, according to a study published in today's edition of Public Library of Science Medicine.

Researchers uncover new toxic mechanism in ALS - Lou Gehrig's disease

Exactly how ALS - Lou Gehrig's disease - damages motor neurons is one of medical science's lingering mysteries. At least six mishaps within cells appear to contribute to the death of the nerves that enable muscle movement, but nothing stands out as the key problem.

New technique points to safer, more efficient vaccination

Researchers have demonstrated a technique that has the potential to reduce the toxicity of vaccines and to make smaller doses more effective, according to a study published in PLoS Pathogens.

Largest post-mortem study of SARS deaths teaches scientists about the disease

Led by John Nicholls of Hong Kong University, researchers from Hong Kong and from Toronto (two of the cities worst affected by the 2003 SARS outbreak) joined forces for a large and detailed study of the bodies of 32 patients who had died from SARS.

Taking an alternative approach to HIV vaccination

Researchers from Baylor College of Medicine have shown that switching off a molecule that helps regulate dendritic cells, specialized white blood cells that activate the immune system, could help the host fight HIV infection.

Fruit bats a reservoir for Ebola virus

IRD researchers have succeeded in the first identification of bats as a potential natural reservoir of Ebola virus. Several epidemics of haemorrhagic fever have raged in the Republic of Congo and Gabon since 2001, hitting both humans and primates simultaneously.

Scientists describe phenomenon in the human genome called transcription-induced chimerism

In the January issue of the journal Genome Research, two teams of scientists describe a widespread phenomenon in the human genome called transcription-induced chimerism (TIC), where two adjacent genes produce a single, fused RNA transcript.

Scientists develop prototype drug to prevent osteoporosis based on cannabinoids produced by body

Substances produced in the body that act like those found in the cannabis plant help preserve bone density, according to researchers at the Hebrew University of Jerusalem.

New model for the origin of rheumatoid arthritis

Rheumatoid arthritis (RA) is one of the most common systemic autoimmune diseases, and one of the least understood. Smoking is the major known environmental risk factor for RA, though little is known about the mechanisms involved.

Caspase 8 gene halts spread of aggressive childhood cancer

A team of cancer researchers has shown that a gene commonly lost during neuroblastoma tumor formation, one of the most aggressive cancers in babies and children, is in fact a "metastasis suppressor" gene.

New pathways linking liver disease to changes in the central nervous system

Liver disease is often associated with "sickness behaviors," such as malaise, listlessness, anorexia, difficulty concentrating, and fatigue. In cholestatic liver diseases (where bile production is impaired) such as primary biliary cirrhosis, fatigue occurs in up to 86 percent of patients.

Brain's endocannabinoids protects neurons from inflammation

Some clinical studies have indicated that marijuana or its active cannabinoid ingredient alleviates symptoms of the inflammatory disease multiple sclerosis (MS).

Herceptin may work better when it is followed by injections of interleukin

A new study suggests that antibody-based cancer drugs might help patients more if they are given with substances that stimulate the immune system.

Surprise discovery helps tackle rabies

In an unexpected discovery, scientists at Jefferson Medical College have found that a tiny change in a rabies virus protein can turn a "safe" virus extremely deadly. The finding has enabled the researchers to refine a vaccine they previously created against rabies in wildlife, making it safer and more effective.

UCLA examines disease-versus-disease interactions

The knowledge that one disease may prevent the onset of another is not new. For example, the discovery that cowpox vaccines can prevent smallpox dates back to 1798.

Technique to reduce the toxicity of vaccines demonstrated

Researchers have demonstrated a technique that has the potential to reduce the toxicity of vaccines and to make smaller doses more effective, according to a study published in PLoS Pathogens.

New gene therapy maybe useful for treating muscular dystrophy

A new gene therapy technique that has shown promise in skin disease and hemophilia might one day be useful for treating muscular dystrophy, according to a new study by researchers at Stanford University School of Medicine.

World's deadliest malaria parasite cloaking gene revealed

The world's deadliest malaria parasite, Plasmodium falciparum, sneaks past the human immune system with the help of a wardrobe of invisibility cloaks. If a person's immune cells learn to recognize one of the parasite's many camouflage proteins, the surviving invaders can swap disguises and slip away again to cause more damage. Malaria kills an estimated 2.7 million people annually worldwide, 75 percent of them children in Africa.

Gene discovery may reinvigorate the body's immune system after fighting viral infections

Like boxers wearied by a 15-round bout, the immune system's CD8 T cells eventually become "exhausted" in their battle against persistent viral infection, and less effective in fighting the disease.
