Innate immune sensors—known as pattern recognition receptors (PRRs)—detect specific molecular components of bacterial or ...

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 ...

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 ...

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 ...

Findings from a new study, led by researchers at Dartmouth's Geisel School of Medicine and published in Nature Immunology, have uncovered key functional differences in macrophages—a type of white ...

Microbial threats against human health are only growing. Luckily, researchers are developing new vaccines that are up to the ...

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 ...

Researchers at LMU have elucidated why certain RNA modifications do not trigger an immune response—a key mechanism for RNA therapeutics. The innate immune system is the body's first line of defense ...

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 ...

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 ...
