Discovery of new arenavirus associated with hemorrhagic fever – first identified in nearly four decades

Scientists at Columbia University's Mailman School of Public Health, the South African National Institute for Communicable Diseases of National Health Laboratory Service (NICD-NHLS), the U.S. Centers for Disease Control and Prevention, and Roche's 454 Life Sciences Corporation have discovered the new virus responsible for a highly fatal hemorrhagic fever outbreak in Zambia and South Africa in late 2008.

Discovery of biochemical signals that help immune cells remember how to fight infection

Immunology researchers at UT Southwestern Medical Center have discovered how two biochemical signals play unique roles in promoting the development of a group of immune cells employed as tactical assassins.

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.

Cytomegalovirus may cause high blood pressure

A new study suggests for the first time that cytomegalovirus (CMV), a common viral infection affecting between 60 and 99 percent of adults worldwide, is a cause of high blood pressure, a leading risk factor for heart disease, stroke and kidney disease.

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.

A potentially better way to make flu virus vaccines

A team of Princeton University scientists may have found a better way to make a vaccine against the flu virus.

FDA approves Creon (pancrelipase) - designed to help those with cystic fibrosis

The U.S. Food and Drug Administration announced that it has approved Creon (pancrelipase), a pancreatic enzyme replacement product designed to help patients with cystic fibrosis and others with exocrine pancreatic insufficiency (EPI) digest and absorb nutrients from foods.

Immune cells in skin fight off infection better than the rest

Scientists at the University of Melbourne have discovered the local action of immune cells in the skin, which could improve treatment of viral skin infections.

Varicella zoster infection causes severe autoimmune hepatitis

Autoimmune hepatitis (AIH) is a chronic liver inflammation of unknown etiology that is characterized by the presence of circulatory autoantibodies and ongoing liver tissue damage.

Researchers discover structure-building role for 2 non-coding RNAs

Most of the DNA in the nucleus of each of our cells is converted into RNA, but only a small fraction of these RNA molecules serve as coding templates for the synthesis of proteins.

New insights into how brain responds to viral infection

Scientists at Columbia University Mailman School of Public Health have discovered that astrocytes, supportive cells in the brain that are not derived from an immune cell lineage, respond to a molecule that mimics a viral infection using cellular machinery similar to that used by classical immune cells in the blood.
