Creation of new brain cells plays an underappreciated role in Alzheimer’s disease

Microglia may play a significant role in disrupting neurogenesis in those with Alzheimer's disease. When mice were given drugs which caused microglial cells to die, neurogenesis returned to normal.

Alzheimer’s drug reverses brain damage from adolescent alcohol exposure

Donepezil, a drug routinely administered to slow cognitive decline in Alzheimer's disease, shows promise in treating damage caused to the brain by adolescent alcohol exposure. The drug reverses neuroinflammation and neuron damage in rats exposed to alcohol during adolescence.

How chronic stress causes brain damage

Chronic stress causes autophagy in adult hippocampal neural stem cells. This results in a decline of hippocampal neurogenesis. Cognitive deficits and mood disorders that arise as a result of chronic stress are a result of autophagic death of hippocampal neural stem cells.

To become, or not to become… a neuron

Bcl6 acts as a driver of neurogenic transition by directly silencing a selection of genes that belong to multiple extrinsic pathways promoting self-renewal. Bcl6 is only expressed in specific subsets of neurons and progenitor cells during brain development.

First step to induce self-repair in the central nervous system

Severed axonal segments signal to Schwann cells to begin actin sphere formation and axon disintegration. If the process is disrupted, axon disintegration is slowed and axon fragments impair nerve regeneration.
