Disruption of immune-system pathway key step in cancer progression

Human immune cells communicate constantly with one another as they coordinate to fight off infection and other threats.

Vaccine candidate successful in blocking Simian version of HIV

Researchers have successfully blocked SIV, the simian version of HIV, using a new technique that could help lead to the development of an effective HIV/AIDS vaccine, the Children's Hospital of Philadelphia. The team also included scientists from Nationwide Children's Hospital in Columbus, Ohio, and the New England Primate Research Center in Boston.

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.

Amino acid glutamine show promise in treating stomach ulcers

Nearly 20 years ago, it was discovered that bacteria known as Helicobacter pylori were responsible for stomach ulcers. Since then, antibiotics have become the primary therapy used to combat the H. pylori infection, which affects approximately six percent of the world population and is also a primary cause of stomach cancer. But today the bacteria is growing increasingly resistant to antibiotics.

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 insights into immune exhaustion

A main reason why viruses such as HIV or hepatitis C persist despite a vigorous initial immune response is exhaustion. The T cells, or white blood cells, fighting a chronic infection eventually wear out.

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.

New genetic clues to treatment of hypertension

An international research team has identified a number of unsuspected genetic variants associated with systolic blood pressure (SBP), diastolic blood pressure (DBP), and hypertension (high blood pressure), suggesting potential avenues of investigation for the prevention or treatment of hypertension.

Money from Bill and Melinda Gates will help beat Dengue fever in Australia

The University of Queensland (UQ) has won a grant of $100,000 grant from the Bill and Melinda Gates Foundation to fight dengue and other mosquito-borne diseases.

Study reveals current multi-component vaccines may need reworking

Current strategies for designing vaccines against HIV and cancers, for instance, may enable some components in multi-component vaccines to cancel the effect of others on the immune system, eliminating their ability to provide protection, according to an article to be published shortly in the Proceedings of the National Academy of Sciences (PNAS).

Wistar Institute obtains U.S. patent for a novel synthetic vaccine technology

The Wistar Institute today obtained a U.S. patent for a novel synthetic vaccine technology with the potential for further development into a universal flu vaccine which could eliminate the need for annual flu shots and protect against future flu pandemics.

Mushrooms may boost the body's natural immune system

The potential for mushrooms to fight influenza is being examined following United States research suggesting the body's natural immune response against viral infections and tumours is boosted through the consumption of white button mushrooms.

New, more effective and less costly method for testing drugs for potential toxicity

Adverse reactions to drugs represent one of the leading causes of death in the United States. But there may be a way to predict who is most likely to suffer a toxic side effect to a drug before they have even taken it.

A more potent vaccine technology

Virginia Tech virologist Chris Roberts' goal is to develop a platform for a flu vaccine that allows rapid modifications to meet new strains of flu.

Discovery of process that controls T cell growth

Identifying one of the processes that plays a role in naïve and memory T-cells' growth and production could one day lead to better vaccines and possibly more effective cancer immunotherapy, said researchers at Baylor College of Medicine and Texas Children's Hospital in a report that appears in the current edition of Nature Immunology.

A universal vaccine to protect against pandemic influenza a step closer

An influenza vaccine that protects against death and serious complications from different strains of flu is a little closer to reality, Saint Louis University vaccine researchers have found.

Oral delivery system for RNAi therapeutics

Researchers at the University of Massachusetts Medical School (UMMS) report on a novel approach to the delivery of small bits of genetic material in order to silence genes using "RNA interference"-and in the process, discovered a potent method of suppressing inflammation in mice similar to what occurs in a range of human diseases.

Senior men more likely than women to die after pneumonia

Differing biological response to infection between men and women may explain higher death rates among older men who are hospitalized with community-acquired pneumonia (CAP).

New animal model for the painful nerve condition sciatica

A newly developed animal model for the painful nerve condition known as sciatica should help researchers diagnose and treat it, according to Duke University bioengineers and surgeons.
