It starts with a sneeze. Someone on the subway didn't cover their mouth and now a cloud of invisible invaders hangs in the ...

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 ...

Some of our biggest threats can come in the tiniest forms—viruses and bacteria. Thankfully, we are born with a built-in ...

Along with defending against pathogens, the body's innate immune system helps to protect the stability of our genomes in ...

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 ...

Inflammation is a vital part of the immune response, but it seems that the system can sometimes go awry, resulting in chronic ...

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 ...

Cancer immunotherapy, which primes the body's immune system to fight off tumors, has historically focused on harnessing T ...

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 ...

Researchers identified a natural 'brake' within the innate immune system: the inhibitory receptor Siglec-E (SigE) and its human counterparts, Siglec-7 and Siglec-9. This receptor helps prevent ...
