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 ...

A Science Immunology Review explains how memory B cells acquire diverse molecular, epigenetic, and tissue-specific programs ...

As scientists gain a deeper understanding of how the body’s immune system remembers pathogens it must fight, the paradigm for ...

However, details of the intervening steps, as researchers have learned in the past 65 years, are quite complex — certain cells carry the flu antigen to the immune system, specific immune cells respond ...

Researchers have discovered that some CAR-T cells engineered to fight cancer and other conditions carry the memory of past encounters with bacteria, viruses and other antigens within them, a finding ...

Memory T cells are a special type of white blood cell that "remember" past infections and vaccines, helping our bodies to quickly respond if we encounter the same germs again. These cells are found ...

A specific extract from the root of the American ginseng plant protects brain connections and improves memory in aged rats.

For decades, dogma dictated that the immune system consisted of two separate branches. Cells of the innate system respond rapidly to molecular patterns shared by a broad array of pathogens. Meanwhile, ...
