 This study examined the effects of genetic variants associated with Alzheimer's disease, AD, on gene expression levels in different brain cells. They found that certain genetic variants were expressed differently in different cells, suggesting that the effects of these variants may vary depending on which type of cell they are expressed in. This could help researchers better understand how genetics affects the progression of AD. This article was offered by Logan Bray's, Sifo Mu, Ricardo de Oliveira Albinas, and others.
