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 ...

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 ...

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 ...

Pathogens are ubiquitous and a constant threat to their hosts, which has led to the evolution of sophisticated immune systems in bacteria, archaea and eukaryotes. Bacterial immune systems encode an ...

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 ...

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 ...

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 ...

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 ...

Phospholipases PLA1, PLA2, PLC, and PLD hydrolyze phospholipids to produce corresponding lysophospholipids and fatty acids. Red arrows indicate the corresponding hydrolysis sites. B) Phospholipases ...

In several disease conditions, including infections and cancers, innate immune activation and nutrient scarcity occur together. A study from St. Jude Children's Research Hospital published today in ...

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. This paves the way for the ...
