New treatment approach for septic Listeria infection

Research underway at the Trudeau Institute could lead to new treatments for people sickened by Listeria and other sepsis-causing bacteria. Dr. Stephen Smiley's laboratory has published a study in the scientific journal Infection and Immunity that supports a new approach to treating these infections.

Researchers identify 42 genetic regions associated with liver function

Researchers have identified a large number of areas in the human genetic code that are involved in regulating the way in which the liver functions, in a new study of over 61,000 people, published today in the journal Nature Genetics.

Scientists discover a way to accurately map typhoid outbreaks in the city

In the mid-nineteenth century, John Snow mapped cases of cholera in Soho, London, and traced the source of the outbreak to a contaminated water pump. Now, in a twenty-first century equivalent, scientists funded by the Wellcome Trust working in Kathmandu, Nepal, have combined the latest in gene sequencing technology and global positioning system (GPS) case localisation to map the spread of typhoid and trace its source.

Penn scientist tracks attitudes and H1N1 vaccination rates on Twitter

A unique and innovative analysis of how social media can affect the spread of a disease has been designed and implemented by a scientist at Penn State University studying attitudes toward the H1N1 vaccine. Marcel Salath-, an assistant professor of biology, studied how users of Twitter -- a popular microblogging and social-networking service -- expressed their sentiments about a new vaccine.

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.
