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 ...

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, ...

The concept of trained immunity has redefined innate immune responses as adaptable, durable, and context dependent. Natural killer (NK) cells, traditionally ...

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 ...

Scientists at Cincinnati Children's have identified how certain immune cells are molecularly programmed to respond faster when the body encounters a familiar threat, shedding light on immune memory ...

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 ...
