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 ...

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 ...

The innate immune system is the body's first line of defense against pathogens and foreign substances. An essential component of this system are pattern recognition receptors, which recognize non-self ...

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 ...

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 ...

A new Review reveals how aging can push the immune system into a paradoxical state, weaker against threats yet more prone to attacking the body’s own tissues.

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 ...

Innate immune sensors – known as pattern recognition receptors (PRRs) – detect specific molecular components of bacterial or viral intruders. The PRRs forward the signals which results in the ...
