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, ...

Innate immunity, orchestrated by pattern recognition receptors (PRRs) including TLRs, NLRs, and the cGAS–STING pathway, forms the foundation of host ...

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 ...

Dozens of new discoveries reveal that defenses evolved by bacteria and viruses billions of years ago still define our own ...

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 ...

Researchers have discovered that mRNA-based COVID-19 vaccines have a persistent effect on the innate immune system. These mechanisms may help the human body to better protect itself against potential ...

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 ...

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 ...

Researchers have shown that innate immune training, also known as trained immunity (TRIM), leads to aggravated bone loss in experimental models of periodontitis and inflammatory arthritis. Clinical ...
