Promising mouse studies and billions of dollars in funding are stoking excitement. But we’ve been here before.

Resting brain stem cells hardly differ from normal astrocytes, which support the nerve cells in the brain. How can almost identical cells perform such different functions? The key lies in the ...

When a neuron ages, it loses synaptic connections with other neurons, it is less able to transmit nerve impulses, and its metabolism is also altered. This process of neuronal aging—inevitable with the ...

In a recent study posted to the bioRxiv* preprint server, researchers performed age-reversing experiments, in vivo and in vitro, in progeroid mice using gene therapy. Study: Gene Therapy Mediated ...

A single protein can reverse the developmental clock on adult brain cells called astrocytes, morphing them into stem-like cells that produce neurons and other cell types, UT Southwestern researchers ...
