A team has identified a previously unknown phase of the immune response. The results challenge long-standing assumptions about the process called 'T-cell priming'. These new insights have significant ...

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 ...

Scientists have discovered novel immune responses that help explain how some individuals avoid getting COVID-19. Using single-cell sequencing, researchers studied immune responses against SARS-CoV-2 ...

In a new experiment, scientists used virtual reality to show that the brain can sense virtual infection to trigger the body’s immune system, before the first microbe ever makes contact. Study: Neural ...

Caption: Human neutrophils visualized under a confocal microscope with cell membranes stained red and nuclei blue. When faced with an infection during food shortages, stress hormones trigger an immune ...

An estimated 2.8 million people worldwide have multiple sclerosis (MS). This autoimmune condition is the result of the immune system damaging parts of the nerves in the brain and spinal cord, which ...
