The paper introduces optimized fluorescence-activated nuclei sorting (FANS) protocols to isolate cell-type-specific nuclei from human and mouse brain tissue for multi-omic analysis.

The paper identifies cell-type-specific DNA methylation differences in autism, revealing female-specific X chromosome alterations in microglia.

This study identifies cell-type-specific DNA methylation dynamics in the human cortex across development, highlighting prenatal periods as critical for epigenomic plasticity and linking changes to neurodevelopmental disorders.

The paper provides guidance for designing and analyzing cell-type specific epigenetic epidemiology studies using DNA methylation data from purified cell populations.

The paper examines sex differences in brain structure at birth in newborns, finding larger brain volumes in males and specific regional differences in gray and white matter volumes between sexes.

The paper characterizes expressed transcripts in the human cortex across development, identifying novel coding sequences with clinical relevance.

The paper develops and validates deconvolution models using DNA methylation data to estimate cell-type proportions in the human cortex, finding glial cells are twice as abundant as neurons and linking cell-type proportions to Alzheimer's disease neuropathology.

The paper identifies DNA methylation signatures in Alzheimer's disease cortex, showing most changes are driven by non-neuronal cell types.

The paper develops a novel epigenetic clock for fetal brain development to predict prenatal age in iPSCs and derived neurons, showing they remain epigenetically fetal despite differentiation.

This study uses long-read RNA sequencing to analyze isoform diversity in human and mouse cerebral cortex, revealing widespread alternative splicing and novel transcripts.

The paper develops a novel DNA methylation clock optimized for human cortex tissue, outperforming existing clocks and highlighting issues with previous associations between DNA methylation age and neurodegenerative phenotypes.
