The immune system can work in two ways: the innate immune system reacts to any foreign invaders that are identified by immune cells that look for such pathogens; but the acquired or adaptive immune ...

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 ...

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 ...

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 ...

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 ...

Researchers at LMU have elucidated why certain RNA modifications do not trigger an immune response—a key mechanism for RNA therapeutics. The innate immune system is the body's first line of defense ...

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

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 ...

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