Antagonizing niche signals regulate the emergence of postnatal neural stem cells and allow enlargement of their pool

The paper identifies ECM remodeling differences between slowly and rapidly dividing RGCs that regulate aNSC emergence and pool size through in vivo perturbation and single-cell RNA-sequencing.

Hmgb2 improves astrocyte to neuron conversion by increasing the chromatin accessibility of genes associated with neuronal maturation in a proneuronal factor-dependent manner

The paper shows that Hmgb2 enhances astrocyte-to-neuron conversion by regulating chromatin accessibility of neuronal maturation genes in response to growth factors.

Daily glucocorticoids promote glioblastoma growth and circadian synchrony to the host

This study shows that daily glucocorticoids influence glioblastoma growth and circadian synchronization with the host, with effects dependent on timing and clock genes.

Stab Wound Injury Elicits Transit Amplifying Progenitor-like Phenotype in Parenchymal Astrocytes

This study identifies injury-induced plastic astrocytes in mice that exhibit self-renewal and neurosphere-forming capabilities, resembling transit-amplifying progenitors in transcriptional profile.

Entrainment of circadian rhythms depends on firing rates and neuropeptide release of VIP SCN neurons

This study identifies how VIP SCN neurons use firing rates and neuropeptide release to entrain circadian rhythms in gene expression and behavior.

Circadian clock neurons mediate time-of-day dependent responses to light

This study investigates how circadian clock neurons in the suprachiasmatic nucleus (SCN) respond to light and mediate time-of-day dependent rhythms in behavior.
