While we tend to quickly forget having been ill or having received a vaccine, the immune system remembers remarkably well. It has memory B cells—"trained" immune cells that circulate throughout the ...

The average human has about 1.8 trillion immune cells. These cells patrol the body for bacteria, viruses, cancers, and other threats. Vaccines enhance this security system by teaching our immune cells ...

University of Pittsburgh School of Medicine and UPMC Hillman Cancer Center scientists have discovered a novel subset of cancer-fighting immune cells that reside outside of their normal neighborhood – ...

Newswise — Bottom Line: Bivalent mRNA booster vaccination not only reactivates memory B cells against ancestral SARS-CoV-2 but also promotes their further maturation in germinal centers, leading to ...

Activated and class-switched memory B cells were enriched at the end of treatment in the patients who went on to clear HBsAg. Five of 21 patients lost hepatitis B surface antigen after stopping ...

At the surface, the immune response to a flu virus is simple. Some cells recognize the pathogen and send a signal to the immune system, and immune cells produce a potentially lifesaving antibody ...

The study, "A transcriptionally distinct subset of influenza-specific effector memory B cells predicts long-lived antibody responses to vaccination in humans,” was published in Immunity. “Our study ...

Aging quietly rewires two of the body’s most influential systems: the immune network and the trillions of microbes living in ...

When cells are healthy, we don't expect them to suddenly change cell types. A skin cell on your hand won't naturally morph into a brain cell, and vice versa. That's thanks to epigenetic memory, which ...
