abstract = {Neural stem cells (NSCs) in the hippocampus generate new
neurons throughout life, which functionally contribute to
cognitive flexibility and mood regulation. Yet adult
hippocampal neurogenesis substantially declines with age and
age-related impairments in NSC activity underlie this
reduction. Particularly, increased NSC quiescence and
consequently reduced NSC proliferation are considered to be
major drivers of the low neurogenesis levels in the aged
brain. Epigenetic regulators control the gene expression
programs underlying NSC quiescence, proliferation and
differentiation and are hence critical to the regulation of
adult neurogenesis. Epigenetic alterations have also emerged
as central hallmarks of aging, and recent studies suggest
the deterioration of the NSC-specific epigenetic landscape
as a driver of the age-dependent decline in adult
neurogenesis. In this review, we summarize the recently
accumulating evidence for a role of epigenetic dysregulation
in NSC aging and propose perspectives for future research
directions.},
