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 mouse study reveals how aging immune cells may impair memory outside the brain, showing that blocking CD8+ T cell activity or their secreted factor, granzyme K, helped restore cognitive performance ...

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 ...

In a groundbreaking study published on October 23, 2025, scientists have successfully reversed brain aging and memory loss in mice. This achievement was made possible through innovative techniques ...

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 ...

The data shows that the brain's primary immune cells decline from age 50 to 75 years and are replaced with elevated inflammatory signatures.

A newly identified protein may hold the key to rejuvenating aging brain cells. Researchers found that boosting DMTF1 can restore the ability of neural stem cells to regenerate, even when age-related ...

An international research team has uncovered new insights into healthy brain aging. The researchers found that aging leads to the accumulation of defective energy molecules in the brains of aged mice, ...
