The immune system has two separate responses, which are orchestrated to optimize protection against pathogens. The first response is known as innate immuni | Immunology ...

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 ...

A team led by researchers at the University of Cologne has identified a protein called ANKIB1 that acts as a volume dial for the body’s frontline immune defenses, controlling how strongly cells ...

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 ...

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” ...

Type 1 diabetes (T1D) is an autoimmune disease characterized by the immune-mediated destruction of pancreatic B cells. While autoreactive T cells are key ...

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 ...

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

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 ...

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 ...

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 ...

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 ...
