Temporal tracking of microglia activation in neurodegeneration at single-cell resolution


ABSTRACT: In this study, we used single-cell RNA-sequencing to gain unprecedented insight into the phenotypic heterogeneity and the transcriptional dynamics of microglia cells during the progression of neurodegeneration. Briefly, by using a severe neurodegeneration mouse model with Alzheimer’s-like pathology and phenotypes (CK-p25 model), we surveyed microglia activation by RNA sequencing longitudinally at fine temporal- and single-cell resolution. In summary, our work identified previously unobserved heterogeneity in the response of microglia to neurodegeneration, discovered novel microglia cell states, revealed the trajectory of cellular reprogramming of microglia in response to neurodegeneration, and uncovered the underlying transcriptional programs. These insights into the molecular programs underlying microglia activation provided by our study may pave the way for designing new rational and efficient strategies to treat Alzheimer’s and other neurodegenerative diseases.
