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 ...

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 ...

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 ...

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 ...

We sometimes hear about the benefits of “boosting” our immune system, but what we really want to do is support our immune system on an ongoing basis. People often think of the immune system as ...

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 ...

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 ...

As part of the body's first line of defense against foreign invaders, macrophages play an integral role in the innate immune ...

A remarkable new way to tackle deadly drug-resistant infections - by supercharging the body's own immune cells rather than ...

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