However, adaptive immune cells—so-named because they can recognize, respond to, and remember specific microbes—require four to seven days to mount a tailor-made defensive. 1 Meanwhile, innate immune ...

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 ...

And importantly, these studies have also shown that "training" the innate immune system has beneficial effects, such as anti-tumor activity and an increased response to fighting infections in ...

However, recent research has challenged this belief, showing that the innate immune system can be trained. This emerging principle, known as trained innate immunity, enables the innate immune system ...

Feb. 28, 2022 — The innate immune system plays a crucial role in regulating host-microbe interactions, and especially in providing protection against pathogens that invade the mucosa.
