Abstract
Microglia are resident immune cells of the brain and are implicated in the etiology of Alzheimer’s disease (AD) and other diseases. Yet the cellular and molecular processes regulating their function throughout the course of the disease are poorly understood. Here, we present a transcriptional analysis of primary microglia from 189 human postmortem brains, including 58 healthy aging individuals and 131 with a range of disease phenotypes, such as 63 patients representing the full clinical and pathological spectra of AD. We identified changes associated with multiple AD phenotypes, capturing the severity of dementia and neuropathological lesions. Transcript-level analyses identified additional genes with heterogeneous isoform usage and AD phenotypes. We identified changes in gene–gene coordination in AD, dysregulation of coexpression modules and disease subtypes with distinct gene expression patterns. Taken together, these data further our understanding of the key role that microglia have in AD biology and nominate candidates for therapeutic intervention. Here the authors provide a comprehensive transcriptomic dataset of human primary microglia for Alzheimer’s disease and healthy aging. They identify dysregulation of immune-related microglial functions as a hallmark of disease.
期刊介绍:
Nature Neuroscience, a multidisciplinary journal, publishes papers of the utmost quality and significance across all realms of neuroscience. The editors welcome contributions spanning molecular, cellular, systems, and cognitive neuroscience, along with psychophysics, computational modeling, and nervous system disorders. While no area is off-limits, studies offering fundamental insights into nervous system function receive priority.
The journal offers high visibility to both readers and authors, fostering interdisciplinary communication and accessibility to a broad audience. It maintains high standards of copy editing and production, rigorous peer review, rapid publication, and operates independently from academic societies and other vested interests.
In addition to primary research, Nature Neuroscience features news and views, reviews, editorials, commentaries, perspectives, book reviews, and correspondence, aiming to serve as the voice of the global neuroscience community.
