What changes happen in the aging brain?

2 days ago

Salk Institute scientists created a comprehensive single-cell atlas of epigenetic changes in the aging mouse brain.
The atlas includes data from eight brain regions and 36 distinct brain cell types, profiling over 200,000 single cells.
Key findings include age-related methylation changes, particularly in non-neuronal cells, and increased activity of transposable elements.
The study utilized spatial transcriptomics to map gene expression, revealing regional differences in aging.
The dataset is publicly available on AWS and GEO, facilitating global research collaboration.
Deep-learning models were developed to predict age-related gene expression changes, aiding future research.
The study highlights the importance of cell type-specific and region-specific understanding of brain aging.
