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 ...

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 ...

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 ...

Scientists discover how innate immunity envelops bacteria. The protein GBP1 is a vital component of our body's natural defense against pathogens. This substance fights against bacteria and parasites ...

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 ...

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 ...

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 ...

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, ...

Secondary infections caused by bacteria or viruses during hospital care remain a long-standing global challenge, despite advances in modern medicine. In particular, mixed bacterial–viral infections in ...

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 ...

A section of Goodsell et al.’s magnificent “Integrative illustration for coronavirus outreach” highlighting the packaging of the viral genetic material (in pink) by the scaffold “nucleocapsid protein” ...
