AIDS drugs from sunflowers

Sunflowers can produce a substance which prevents the AIDS pathogen HIV from reproducing, at least in cell cultures. This is the result of research carried out by scientists at the University of Bonn in cooperation with the caesar research centre.

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.

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.

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.

Clarithromycin reduces recurrent cardiovascular events in patients without periodontitis

Periodontitis, an infection of the gingiva and tooth-supporting tissues, may influence the effectiveness of antibiotics used for the prevention of recurrent cardiovascular events.

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.

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.

Targeted cancer therapies: Another step forward

While it is clear that the treatment of cancer has already begun to undergo a paradigm shift with the inclusion of innovative targeted therapies into current regimens, it would be wrong to assume these products will entirely replace traditional chemotherapy as the standard treatment for cancer sufferers.

Children could be saved from neuroblastoma using antibody therapy

Combination of T cell, antibody to neuroblastoma cells and molecule that spurs T cell growth is designed to treat low initial tumor levels or small cancer cell populations that survive initial treatment, according to St. Jude.

Good results with cervical cancer vaccine in young girls

Drug company GlaxoSmithKline have had a good result with their new vaccine which was designed to prevent infection with the virus that causes cervical cancer.

New cell findings have implications for cancer, immune disorders

It all started 5 years ago when a University of Calgary neuroscientist sent blood from a patient with a neurological disorder to the laboratory of Dr. Marvin Fritzler, professor of medicine / biochemistry & molecular biology at the University of Calgary Faculty of Medicine.

MorphoSys signs agreement with Merck

MorphoSys AG announced today that it has signed a five-year license agreement with U.S. pharmaceutical company Merck & Co., Inc. for the use of MorphoSys’s HuCAL GOLD and AutoCAL technologies in research and development of human therapeutic antibodies.

A colonization factor links Vibrio cholerae environmental survival and human infection

Opening a new door to an effective vaccine and therapy for a disease that strikes thousands annually, researchers at Dartmouth Medical School discovered that the bacteria that causes the intestinal disease Cholera spreads in the environment in much the same way it infects humans.

Anti-Abeta42 and Anti-Abeta40–specific monoclonal antibodies attenuate amyloid deposition in an Alzheimer disease mouse model

Current hypotheses suggest that it is the accumulation over time of amyloid beta peptide 1–42 (Abeta42) that triggers changes in the brain that lead to cognitive dysfunction in Alzheimer's disease.

SPARC promotes heart muscle formation from stem cells

The protein SPARC plays a key role in the development of heart muscle in the embryo. An Austrian Science Fund FWF project has discovered this previously unknown role of SPARC.

New study sheds light on role of type II collagen in rheumatoid arthritis

Rheumatoid arthritis (RA) is an autoimmune disease which gradually erodes cartilage and bone and is characterised by chronic inflammation of the joints.

New anthrax antibody

A new anthrax antibody engineered by scientists at The University of Texas at Austin protects and defends against inhalation anthrax without the use of antibiotics and other more expensive antibodies.

Contact with pigs increases risk of animal flu viruses

Farmers, veterinarians and meat processors who routinely come into contact with pigs in their jobs have a markedly increased risk of infection with flu viruses that infect pigs, according to a study funded in part by the National Institute of Allergy and Infectious Diseases (NIAID).
