Study finds vitamin D is critical in human immune response to tuberculosis

"Vitamin D is needed to activate the immune system's response to tuberculosis (TB)," a finding that "could lead to new treatments for the lung disease," researchers from the University of California in Los Angeles (UCLA) said in a study published Wednesday in the journal Science Translational Medicine, Agence France-Presse reports.

Researchers demonstrate that iPS stem cells may be used for gene therapy

This research, published on Oct. 12 on the Nature review website, provides evidence of a major concept could pave the way for the future use of these stem cells to treat humans, through perspective gene therapies.

Stopping necroptosis in keratinocytes prevents skin inflammation

The outer layer of the skin, called the epidermis, forms a critical physical and immunological wall that serves as the body's first line of defense against potentially harmful microorganisms. Most of the epidermis consists of cells called keratinocytes that build a mechanical barrier but also perform immune functions.

Vitamin D plays an essential role in the body's fight against TB

Not just important for building strong bones, an international team of scientists has found that vitamin D also plays an essential role in the body's fight against infections such as tuberculosis.

Novel link between cell surface sugars, Darwinian sexual selection, and immune function

Researchers at the University of California, San Diego School of Medicine say that losing the ability to make a particular kind of sugar molecule boosted disease protection in early hominids, and may have directed the evolutionary emergence of our ancestors, the genus Homo.

Virginia Bioinformatics Institute releases upgraded ENISI software

Researchers with the Virginia Bioinformatics Institute at Virginia Tech have released an upgrade to the institute's ENteric Immunity SImulator (ENISI) software, which models immune responses to beneficial and harmful bacteria that enter the gastrointestinal tract of mice, pigs, and humans.

Lipomannan on TB bacterium's outer cell surface can block TNF production

The bacterium that causes tuberculosis has a unique molecule on its outer cell surface that blocks a key part of the body's defense. New research suggests this represents a novel mechanism in the microbe's evolving efforts to remain hidden from the human immune system.

DNA primer vaccine enhances immune response to H5N1 avian influenza vaccine

The immune response to an H5N1 avian influenza vaccine was greatly enhanced in healthy adults if they were first primed with a DNA vaccine expressing a gene for a key H5N1 protein, researchers say.

CNRS researcher wins 2011 Nobel Prize in physiology or medicine for immunology work

The 2011 Nobel Prize in physiology or medicine has been awarded to Jules Hoffmann, a French citizen native of Luxembourg, CNRS senior researcher emeritus and professor at the university of Strasbourg, jointly with Bruce A. Beutler for their discoveries concerning the activation of innate immunity.

Researchers determine structure of RIG-I protein linked with viral infections

Researchers at Rutgers and UMDNJ-Robert Wood Johnson Medical School have determined the structure of a protein that is the first line of defense in fighting viral infections including influenza, hepatitis C, West Nile, rabies, and measles.

Study provides insight into earliest stages of some cancers

A novel technique that enables scientists to measure and document tumor-inducing changes in DNA is providing new insight into the earliest events involved in the formation of leukemias, lymphomas and sarcomas, and could potentially lead to the discovery of ways to stop those events.

X-chromosome related microRNA may impact immunity and cancer

As anyone familiar with the phrase 'man-flu' will know women consider themselves to be the more robust side of the species when it comes to health and illness. Now new research, published in BioEssays, seems to support the idea. The research focuses on the role of MicroRNAs encoded on the X chromosome to explain why women have stronger immune systems to men and are less likely to develop cancer.

Columbia University receives CFI grant to investigate causes of chronic fatigue syndrome

The Chronic Fatigue Initiative (CFI) - a new privately funded research directive focused on chronic fatigue syndrome - announced a substantial grant to a Columbia University research team to investigate the role of pathogens in causing chronic fatigue syndrome. The pathogen discovery and pathogenesis program will be led by Drs. Ian Lipkin and Mady Hornig of the Center for Infection and Immunity.

Researchers modify HIV in a way that makes it no longer able to suppress immune system

Researchers at Johns Hopkins have modified HIV in a way that makes it no longer able to suppress the immune system. Their work, they say in a report published online September 19 in the journal Blood, could remove a major hurdle in HIV vaccine development and lead to new treatments.

Longer looks: Breast cancer fundraising; treating autism

Though breast cancer researchers and advocates perpetually plead for more money, the disease is, in fact, awash in it. Last year, the National Institutes of Health, the nation's top agency for health-related research, allocated $763 million to the study of breast cancer, more than double what it committed to any other cancer.

NIH honors Utah biochemist with Pioneer Award for dsRNA research

University of Utah biochemist Brenda L. Bass, Ph.D., has dedicated her career to following the path less traveled.

State roundup: Consumer advocates oppose Ga. request to ease rules on insurers' profits

The state's request to ease new federal restrictions on health insurer spending would cost Georgia insurance policyholders an estimated $34 million in rebates, consumer advocacy groups say.

Whooping cough vaccine may lose protective capacity in 3 years: Study

The whooping cough vaccine given to babies and toddlers loses much of its effectiveness after just three years. Doctors believe that could help explain a recent series of outbreaks in the U.S. among children who were fully vaccinated, a study suggests.

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.

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.
