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 ...

A newly recognized set of T helper cells seems to guard against aging by eliminating harmful senescent cells. Their presence in supercentenarians suggests they may be a key to maintaining a 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 ...

Declining immune responsiveness with age may be driven by changes in immune cells — not by inflammation, as previously thought. When you purchase through links on our site, we may earn an affiliate ...

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