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 ...

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 ...

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 ...

Innate immune sensors – known as pattern recognition receptors (PRRs) – detect specific molecular components of bacterial or viral intruders. The PRRs forward the signals which results in the ...

Findings may support development of more refined personalized breast cancer risk prediction models for BRCA1 pathogenic ...

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 ...

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 ...

Sat, January 24, 2026 at 2:56 PM UTC The immune system is the body’s natural defense network that helps to keep you healthy from things like bacteria, viruses, and parasites. It’s a complex network of ...
