The immune system can work in two ways: the innate immune system reacts to any foreign invaders that are identified by immune cells that look for such pathogens; but the acquired or adaptive immune ...

When the first cells appeared on Earth approximately 3.8 billion years ago, viruses were already here to greet them. 1 Ever since, viruses have been devising ways to infect cells, and cells have been ...

In a world-first breakthrough, scientists have discovered how a sugary “cloak” helps bowel cancer hide from the immune system, and how stripping it away could turn the body’s anti-cancer defenses back ...

Researchers at LMU have elucidated why certain RNA modifications do not trigger an immune response—a key mechanism for RNA therapeutics. The innate immune system is the body's first line of defense ...

Taken together, these advances suggest that part of age-related immune decline is driven by specific, potentially reversible ...

Vaccines boost the immune system's ability to fight off diseases. Vaccines undergo rigorous testing to ensure safety and effectiveness. Widespread vaccination contributes to herd immunity, protecting ...

Researchers led by the University of Geneva and École Polytechnique Fédérale de Lausanne report that neural anticipation of virtual infection triggers an immune response through activation of innate ...

An immune system defect makes affected individuals vulnerable to severe viral diseases such as influenza or COVID-19. It is caused by the body's own antibodies, which inhibit important defense ...

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 ...
