Pioneering research led by Brazilians describes the immune system's reactions in detail in the first living patient to receive a genetically modified pig kidney transplant.

Filoviruses are negative-sense and single-stranded ribonucleic acid (RNA) viruses. The most well-known human-infecting filoviruses are marburgviruses and ebolaviruses. Infection can result in ...

When pathogens attack the body, the innate immune system goes to work protecting against the invading disease. The innate immune system is the first line of defense. It detects precisely what the ...

Our immune system is divided into two main branches: innate and adaptive. Innate immune cells act as a first line of defense, quickly responding to invaders, while adaptive immune cells take a longer ...

Researchers have discovered the molecular mechanism by which the innate immune system recognizes HIV-1, potentially contributing to the development of future treatments. HIV-1 is a virus that actively ...

Immunity acquired from a Covid infection provides strong, lasting protection against the most severe outcomes of the illness, according to research published Thursday in The Lancet — protection, ...

Mammalian immunity has long been thought to rely solely on proteins and specialized immune cells. However, a newly proposed concept—RNA immunity—is reshaping this perspective. In a recent publication ...

People can develop temporary natural immunity after recovering from COVID-19. However, vaccines are the best way to train the immune system to recognize viruses. When a vaccinated person encounters ...
