| Open AccessSingle-cell DNA methylome and 3D multi-omic atlas of the adult mouse brain
Methylome-based clustering and cross-modality integration with companion datasets from the BRAIN Initiative Cell Census Network enabled the construction of a 3D multi-omic genome atlas of the adult mouse brain featuring thousands of cell-type-specific profiles.

| Open AccessBrain-wide correspondence of neuronal epigenomics and distant projections
This study uses epi-retro-seq to link single-cell epigenomes and cell types to long-distance projections for neurons dissected from different regions projecting to different targets across the whole mouse brain.

| Open AccessSpatial profiling of chromatin accessibility in mouse and human tissues
Spatial-ATAC-seq—spatially resolved chromatin accessibility profiling of tissue sections using next-generation sequencing—delineated tissue-region-specific epigenetic landscapes in mouse embryos and identified gene regulators involved in the development of the central nervous system and the lymphoid tissue.

| Open AccessGene regulation by gonadal hormone receptors underlies brain sex differences
A study maps neuronal genomic targets of oestrogen receptor-α and shows how they coordinate brain sexual differentiation, concluding that the genome remains responsive to hormonal changes after structural dimorphisms have been established.

| Open AccessDNA methylation atlas of the mouse brain at single-cell resolution
A comprehensive survey of the epigenome from 45 regions of the mouse cortex, hippocampus, striatum, pallidum and olfactory areas using single-nucleus DNA methylation sequencing enables identification of 161 cell clusters with distinct locations and projection targets and provides insights into the regulatory landscape underlying neuronal diversity and spatial regulation.

Histone serotonylation is a permissive modification that enhances TFIID binding to H3K4me3
In serotonin-rich tissues, tissue transglutaminase 2 is able to attach serotonin to a glutamine residue in histone H3; this modification mediates permissive gene expression in these tissues.

Acetyl-CoA synthetase regulates histone acetylation and hippocampal memory
The metabolic enzyme acetyl coenzyme A synthetase directly regulates gene expression during memory formation by binding to specific genes and providing acetyl coenzyme A for histone acetylation.

| Open AccessConserved epigenomic signals in mice and humans reveal immune basis of Alzheimer’s disease
Analysis of transcriptional and epigenomic changes in the hippocampus of a mouse model of Alzheimer’s disease shows that immune function genes and regulatory regions are upregulated, whereas genes and regulatory regions involved in synaptic plasticity, learning and memory are downregulated; genetic variants associated with Alzheimer’s disease are only enriched in orthologues of upregulated immune regions, suggesting that dysregulation of immune processes may underlie Alzheimer’s disease predisposition.

Histone H2A.Z subunit exchange controls consolidation of recent and remote memory
The authors identify a specific histone variant as a memory-suppressor that is initially reduced in expression within the hippocampus during memory formation; as a memory is consolidated to the cortex, reduced histone association with specific plasticity genes is observed, promoting stabilization of the memory.

Activity-dependent phosphorylation of MeCP2 threonine 308 regulates interaction with NCoR
Rett syndrome is caused by mutations in MeCP2, and this study identifies a site on MeCP2, T308, whose phosphorylation is regulated by neuronal activity: phosphorylation of T308 blocks the interaction of MeCP2 with the NCoR co-repressor complex, suppressing MeCP2's ability to repress transcription, and mice carrying mutations of MeCP2 T308 show Rett-syndrome-related symptoms.

An epigenetic blockade of cognitive functions in the neurodegenerating brain
Histone deacetylase 2 is shown to suppress genes involved in cognitive function epigenetically, potentially opening the door to treatments for Alzheimer’s and other neurodegenerative diseases by developing HDAC2-selective inhibitors.
