Innate immunity constitutes the body’s first line of defence against invading pathogens. This ancient, evolutionarily conserved system is activated within minutes of encountering foreign agents, ...

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 ...

A new review by Dr. Ruyuan Wang and an international team of researchers explores the complex interactions between the innate and adaptive immune systems, shedding light on regulatory mechanisms in ...

When thinking about the immune system, most people think about B and T cells and how they can be trained to recognize pathogens, preventing re-infections. Besides this "adaptive" immune system, we ...

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 ...

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 ...

The BCG vaccine protects against tuberculosis, but by inducing trained immunity it also protects against many more respiratory infections. International research led by the Radboudumc shows how this ...

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 ...
