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 ...

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 ...

The ability of cells in the human body to recognize structural features of invading pathogens to activate protective antipathogen defences is the cornerstone of innate immunity. Sensing these ...

The immune system is traditionally divided into innate and adaptive immunity, distinguished by specificity and memory. Innate immunity, present in all cellular organisms, offers a rapid, nonspecific ...

Our immune system is divided into two main branches: innate and adaptive. Innate immune cells act as a first line of defense, quickly responding to invaders, while adaptive immune cells take a longer ...

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 ...

Along with defending against pathogens, the body's innate immune system helps to protect the stability of our genomes in unexpected ways—ways that have important implications for the development of ...

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 ...

Unlike transient innate immune activation, trained immunity is characterized by long-lasting but reversible functional reprogramming of monocytes, macrophages, natural killer (NK) cells, and ...

The novel coronavirus 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 ...
