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 ...

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 ...

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

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 ...

Sepsis arises from a dysregulated host response to infection, characterised by an initial surge of innate immune activation that can precipitate widespread inflammation, tissue injury and organ ...

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 ...
