Innate immune sensors—known as pattern recognition receptors (PRRs)—detect specific molecular components of bacterial or ...

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 ...

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 ...

Study reveals how two proteins cooperate in a key early step of antiviral detection, as reported by researchers at Science ...

Microbial threats against human health are only growing. Luckily, researchers are developing new vaccines that are up to the ...

Bacteria have evolved sophisticated antiphage systems that halt phage replication upon detecting specific phage triggers. Identifying phage triggers is crucial to our understanding of immune ...

An investigational Toll-like receptor (TLR) antagonist was effective in reducing biomarkers and clinical symptoms of systemic lupus erythematosus (SLE) in a pilot trial, evidence that the innate ...

In the realm of medical advancements, a universal vaccine that can protect against any pathogen has long been a Holy Grail—and about as elusive as a mythological vessel. But Stanford Medicine ...
