During vaccination, the immune system is purposefully exposed to weakened, inactivated, or a component of pathogens so that the body can recognize their molecular structures in the future and mount a ...

Cedars-Sinai researchers created “young” immune cells from human stem cells that reversed cognitive decline and Alzheimer’s symptoms in mice. The treated animals showed better memory and healthier ...

Researchers have used an experimental mRNA therapy to make old immune cells in mice behave as if they were young again, ...

In other words, the flu shot might still deliver the right viral components, but if the memory T cells aren't functioning properly, the body struggles to respond effectively. How this could lead to ...

A trio of mRNA molecules could help guard against the harmful effects of aging on immune cells, a study in mice finds. A new ...

Pre-wired ability in ‘resting’ T cells to remember past viral foes discovered, a promising breakthrough for targeted cancer therapies. A team of immunologists at the University of Massachusetts ...
