NIAID Scientists Link Cases of Unexplained Anaphylaxis to Red Meat Allergy
November 28, 2017

While rare, some people experience recurrent episodes of anaphylaxis—a life-threatening allergic reaction that causes symptoms such as the constriction of airways and a dangerous drop in blood pressure—for which the triggers are never identified. Recently, researchers at the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, found that some patients’ seemingly inexplicable anaphylaxis was actually caused by an uncommon allergy to a molecule found naturally in red meat.

Scientists Develop Infection Model for Tick-borne Flaviviruses
August 22, 2017

National Institutes of Health (NIH) scientists have filled a research gap by developing a laboratory model to study ticks that transmit flaviviruses, such as Powassan virus.  Powassan virus was implicated in the death of a New York man earlier this year. The unusual model involves culturing organs taken from Ixodes scapularis ticks and then infecting those organ cultures with flaviviruses, according to researchers at Rocky Mountain Laboratories, part of NIH’s National Institute of Allergy and Infectious Diseases (NIAID).
