A team of scientists lead by prof. Stein Aerts (VIB-KU Leuven) is the first to map the gene expression of each individual brain cell during aging in fruit flies. Their resulting “cell atlas” provides unprecedented insights into the workings of the brain as it ages. Published today in the scientific journal Cell, the atlas is heralded as an important first step in the development of techniques that can contribute to a better understanding of human disease development.
