The paper shows that cell identity and regulatory logic are preserved during brain aging, but cell-type-specific changes occur in DNA modifications and gene expression.

The paper examines how aging and Nrf2 deletion affect visual function and gene expression in the retina and RPE-choroid, finding exacerbated age-related declines in Nrf2-deficient mice.

The paper identifies differential DNA modifications across CNS cell types and their relationship with gene expression using a novel mouse model and epigenomic sequencing.

The paper compares tamoxifen-mediated cre induction efficiency and specificity in young and old mice, finding no significant difference in microglial labeling or translatomic changes.

The paper identifies sex differences in microglial transcriptomic and translatomic profiles in aging mouse hippocampus, highlighting female-biased senescence and disease-associated signatures linked to Alzheimer's disease.

The paper identifies microglia as the primary source of MHC-I in mice and humans, showing age-related and Alzheimer's-associated increases in MHC-I expression and related receptors.

The paper investigates how chromosomal content and gonadal sex influence gene expression and DNA modification patterns in mouse hippocampi, revealing sex chromosome-specific regulatory effects.

The paper compares microglia isolation techniques and shows that transcription/translation inhibitors reduce ex vivo activation artifacts during cell preparation.

The paper introduces a NuTRAP method to isolate RNA and DNA from specific CNS cell types, revealing cell type-specific epigenetic and transcriptomic differences in microglia and astrocytes.
