Researchers release large-scale gene-expression atlas of the aging mouse brain

A team of scientists has compiled a large single-cell gene-expression dataset mapping how brain cells change across aging in mice, published via a Nature-affiliated report. The dataset catalogs expression patterns across numerous cell types and brain regions, intended as a resource for the broader research community.

Study finds blood-derived cells taking over as brain's immune cells in old age

Researchers report that as the human brain ages, its resident immune cells known as microglia are increasingly replaced by cells originating from the bloodstream. This shift in the brain's immune population appears to be a natural part of aging rather than a result of disease.
