He began searching for novel parasite-fighting immune cells. McKenzie knew that IL-25 triggers a class of T cells called type-2 helper T cells (Th2s) to proliferate and produce IL-13, and he wondered ...

In 2015, fruit flies were sent to International Space Station to study how microgravity and the space environment affect the ...

Researchers have shown that innate immune training, also known as trained immunity (TRIM), leads to aggravated bone loss in experimental models of periodontitis and inflammatory arthritis. Clinical ...

Research from Radboud university medical center reveals that T cells from the adaptive immune system can manipulate the memory of innate immune cells. Previously, it was believed that the memory of ...

Scientists generally agree that eukaryotes, the domain of life whose cells contain nuclei and that includes almost all multicellular organisms, originated from a process involving the symbiotic union ...

SARS-CoV-2 has an enzyme that can counteract a cell's innate defense mechanism against viruses, explaining why it is more infectious than the previous SARS and MERS-causing viruses. The discovery may ...

Along with defending against pathogens, the body's innate immune system helps to protect the stability of our genomes in unexpected ways—ways that have important implications for the development of ...

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 ...

We sometimes hear about the benefits of “boosting” our immune system, but what we really want to do is support our immune system on an ongoing basis. People often think of the immune system as ...

For decades, dogma dictated that the immune system consisted of two separate branches. Cells of the innate system respond rapidly to molecular patterns shared by a broad array of pathogens. Meanwhile, ...
