A pizza shop with 30 delivery people ought to be able to deliver a lot of pizzas—if their cars don’t break down on the way. Likewise, genes that produce a lot of messenger RNA (mRNA) molecules can build a lot of proteins—if these molecules don’t fall a…
A research team from Umeå University, Sweden, in collaboration with Ghent University, Belgium, has made a groundbreaking discovery about how the body’s first immune defense, neutrophils, orchestrate the mobilization of zinc to fight microbes.
A newly discovered “timekeeper” for fighting infections dramatically shapes the body’s immune defenses, offering insight as to why antiviral T cell response varies throughout the day, according to UT Southwestern Medical Center researchers.
Macrophages are the first line of defense of the immune system, helping fight infections and keeping tissues healthy. But in the context of some chronic diseases, these immune cells undergo changes and become pathogenic, helping drive disease and creat…
A new study led by the Centenary Institute and the University of Sydney shows that a nasal vaccine could offer powerful protection against COVID-19. It works by stopping infection in the nose before the virus spreads through the body.
Researchers at McMaster University have discovered that a rare but dangerous reaction to a widely used blood thinner is caused by a single antibody—overturning decades of medical misunderstanding and opening the door to more precise ways of diagnosing …
Antibodies are the critical targeting agents of the immune system and the crux of immune therapy and vaccine development, but studying them is slow, expensive and labor-intensive. Now, researchers at the University of Illinois Urbana-Champaign have dev…
The body has an intricate system to defend against infections where each type of immune cell plays a distinct role. Now, a study led by researchers from the Penn State College of Medicine has uncovered a new function of the immune cells that are known …
Scientists from Duke-NUS Medical School, in collaboration with researchers in Nepal, have found that waning immunity to Japanese encephalitis virus (JEV) may increase the risk of more severe dengue disease in humans.
Basophils, a type of white blood cell, promote recovery from acute respiratory distress syndrome (ARDS) in mice, according to researchers at Science Tokyo. In a mouse model of ARDS, basophils were found to release interleukin-4 (IL-4), which suppresses…
