The innate immune system serves as the body's first line of defence, rapidly detecting and responding to external pathogens and internal damage. Recent advances in the field have highlighted the ...

Innate lymphoid cells, which curiously behave like T cells even though they don’t recognize specific antigens, show promise as a potential cancer therapeutic. In the years that followed, other groups ...

This article was published in Scientific American’s former blog network and reflects the views of the author, not necessarily those of Scientific American The very first line of defence against any ...

Humans are protected by two branches of the immune system. Innate immunity provides built-in defense against widespread characteristics of bacteria and viruses, while adaptive immunity memorizes ...

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 ...

Unlike transient innate immune activation, trained immunity is characterized by long-lasting but reversible functional reprogramming of monocytes, macrophages, natural killer (NK) cells, and ...

When a transplanted organ arrives, it’s like a controlled burn that risks becoming a wildfire. The body’s innate immune system senses damage signals, like heat shock proteins (HSP70), and sounds the ...

Cancer immunotherapies, including cancer vaccines, harness and amplify the immune system’s natural ability to detect and attack cancer cells. In this illustration, immune T cells (pink) attach to a ...

Research 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 innate immune cells operated ...

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 ...

Damaging variants in genes involved in a rapid immune response (innate immunity) are significantly linked to earlier breast ...
