New trick of tumors

Tumors have an arsenal of tricks to help them sidestep the immune system. A study published on September 19 in the Journal of Experimental Medicine reveals a new trick—the ability to keep tumor-fighting T cells out by disabling a T cell-attracting protein within the tumor core.

Water plays a decisive role in biologically active enzyme substrate compounds

In biologically active enzyme substrate compounds, as can be found in medicines, water plays a more decisive role than has been imagined up to now. The surrounding water acts like an "adhesive", in order to keep the substrate at the right place on an enzyme.

Immune system uses zinc to destroy tuberculosis bacillus, E. coli

A new natural defense mechanism against infections has been evidenced by an international team led by researchers from CNRS, Inserm, the Institut Pasteur and the Université Paul Sabatier - Toulouse III.

Scientists discover how liver destroys immune T-cells

Scientists at the Centenary Institute in Sydney have seen for the first time (in mice) how the liver goes independent, engulfing and destroying the body's defence troops-T-cells.

Simple checklist to help the whole family excel in nutritional basics

It's September, and that means new clothes, backpacks, school supplies, and agendas — all tools required to keep your children, whether in elementary, high school or post-secondary levels, on a well-stocked, educational journey to success. But beyond equipping your children with the external fundamentals to good grades, are you also providing them with the best nutrients necessary for optimal learning, focus, concentration, energy and overall well-being? And as parents juggling hectic schedules, do you also pass the grade?

UNC researchers reveal genetic underpinnings of Foxp3-expressing regulatory T cells

Within the immune system, a subtle balance exists between the cells that destroy alien pathogens and those that preserve the body's own tissues. When the balance gets out of whack, the cells that normally target viruses or bacteria can go astray, attacking innocent cells and causing autoimmune and inflammatory disease.

Positive data from NovaDigm's NDV-3 vaccine preclinical study on VVC

NovaDigm Therapeutics, a company developing innovative vaccines for fungal and bacterial infections, today announced the presentation of positive data from a preclinical study evaluating the efficacy its NDV-3 vaccine in a model of vulvovaginal candidiasis (VVC), which is primarily caused by Candida albicans.

Positive Phase 1 data for NovaDigm NDV-3 vaccine presented at 51st ICAAC

NovaDigm Therapeutics, a company developing innovative vaccines for fungal and bacterial infections, today announced the presentation of positive Phase 1 data for its NDV-3 vaccine program at the 51st Interscience Conference on Antimicrobial Agents and Chemotherapy (ICAAC).

NTNU genetic research shows best recipe to limit risk of lifestyle-related diseases

What should we eat? Answers abound in the international media, all of which rely on their interpretation of recent medical literature to come up with recommendations for the healthiest diet. But what if you could answer this question at a molecular level - what if you could find out how our genes respond to the foods we eat, and what this does to the cellular processes that make us healthy - or not? That's precisely what biologists at the Norwegian University of Science and Technology have done.

Gamers solve molecular structure of retrovirus enzyme

Gamers have solved the structure of a retrovirus enzyme whose configuration had stumped scientists for more than a decade. The gamers achieved their discovery by playing Foldit, an online game that allows players to collaborate and compete in predicting the structure of protein molecules.

New York Times examines international response to Somali famine

"Twenty years after the central government collapsed," Somalia is facing drought, food insecurity and conflict larger in scale than when famine conditions hit the nation in the 1990s, "[a]nd given the world's limited interest in a major intervention, that is not likely to change anytime soon," the New York Times reports in a news analysis on the situation.

Novel therapies remove the brakes cancer puts on the immune system

Some of the newest therapies in the war on cancer remove the brakes cancer puts on the immune system, Georgia Health Sciences University researchers report.

New insight into how nervous system regulates immunity

Scientists have identified a surprising new role for a new type of T cell in the immune system: some of them can be activated by nerves to make a neurotransmitter (acetylcholine) that blocks inflammation. The discovery of these T cells is novel and suggests that it may be possible to treat inflammation and autoimmune diseases by targeting the nerves and the T cells. The study was published this week in Science.

Vesicular stomatitis virus kills cancer cells

In a new project, researchers from LIFE - the Faculty of Life Sciences at the University of Copenhagen - document that the vesicular stomatitis virus (VSV) plays a previously unknown dual role in the prevention of a number of cancers. The new findings show that the virus both kills cancer cells and stops the expression of the molecules which certain types of cancer cells produce to hide from the immune system.

Adult stem cells hold hope for treatment of lupus

With a patient's own adult stem cells, there is new hope for the intractable autoimmune disease lupus - systemic lupus erythematosus (SLE) - which is difficult to cure.

PopART project awarded $37 million study grant for HIV prevention in Africa

A team of researchers led by Professor Richard Hayes at the London School of Hygiene and Tropical Medicine has been awarded $37 million to test an innovative combination of strategies to prevent HIV in African countries.

Follow-up study of HIV vaccine trial provides clues for continued research

"After two years of analyzing the results of the largest AIDS vaccine clinical trial ever held -- called RV144 -- researchers say they have found two ways the immune system can respond, which could predict whether those inoculated will be protected or are more likely to become infected with HIV," CNN's health blog "The Chart" reports.

Novel imaging technique reveals new visual resolution of NK cell action

Scientists reveal in more detail than ever before how white blood cells kill diseased tissue using deadly granules, in research published today in PLoS Biology.

Animals burn protein during long, cold hibernation

When Arctic ground squirrels are getting ready to hibernate they don't just get fat - they pack on muscle at a rate that would make a bodybuilder jealous. And they do it without suffering the harmful effects that high levels of testosterone and other anabolic steroids usually cause. University of Toronto Scarborough (UTSC) researchers have started to untangle how the squirrels manage it, and their results could someday have implications for human health.
