First study of humans with a rare immunodeficiency reveals how the immune system protects the body against pathogens known to cause serious diseases, such as tuberculosis and COVID-19. The research ...

Unexpected findings have emerged about how and when certain infection-killing white blood cells decide to form memories about their encounters with a pathogen. It has been known for decades that these ...

Coating of specific sugars on some pathogens triggered a resistance effect. A set of sugars found on some disease-causing pathogens helps those pathogens fight the body’s natural defenses as well as ...

During infection, reversible switch permits flexible formation of memory T cells, long-lived blood cells that can remember pathogen encounters and respond upon reinfection. Unexpected findings have ...

Why can the human immune system often remember a vaccination for a whole lifetime? Researchers at ...

The body defends itself against pathogens by depriving them of vital iron. However, this strategy doesn't always succeed against Salmonella. Researchers at the University of Basel have discovered that ...

An innovative approach supercharges the innate immune system to provide a first line of defence against respiratory ...

Most humans have long-lived infections in various tissues—including in the nervous system—that typically do not result in disease. The microbes associated with these infections enter a latent stage ...

Simply the smell of seafood can make those with an allergy to it violently ill — and therefore more likely to avoid it. The same avoidance behavior is exhibited by people who develop food poisoning ...

Multicellular organisms are a mosaic of different cells, tissues, and systems, each with their own specific function and interactions with other cells within the organism and/or the larger environment ...

Bats have been increasingly identified as hosts for zoonotic pathogens, including but not limited to viruses, bacteria, and protozoa. With few exceptions, ...
