Innate Immunity is a nonspecific host defense mechanism against foreign antigens. It is the first line of defense in a host and occurs immediately or within hours after exposure. This type of immunity ...

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 ...

In a recent study published in Nature Immunology, researchers analyzed the innate and adaptive responses to the messenger ribonucleic acid (mRNA)-based BNT162b2 coronavirus disease 2019 (COVID-19) ...

In recent years, the field of immunology has increasingly focused on the role of glycolipids and sphingolipids in the differentiation and function of innate immune cells, such as macrophages, ...

Scientists have long believed that a newborn’s immune system was an immature version of an adult’s, but research from Cornell University shows that newborns’ T cells—white blood cells that protect ...

A section of Goodsell et al.’s magnificent “Integrative illustration for coronavirus outreach” highlighting the packaging of the viral genetic material (in pink) by the scaffold “nucleocapsid protein” ...

Collaborative team from UMass Amherst and Seattle Children’s Research Institute uncovers how prior exposure to bacteria changes the lung’s innate immune response—and what it might mean for vaccines ...

In 1901, Paul Ehrlich conducted one of the landmark experiments in immunology. While studying the immune response in goats using blood from other animals, ...

Not everyone who is exposed to SARS-CoV-2, the virus that causes COVID, gets the disease. New research published in June in Nature may partly explain why: In a 2021 experiment called a challenge study ...
