- Boosting one protein helps the brain fight Alzheimer’s
Scientists found that increasing the Sox9 protein enhances astrocyte activity, reducing Alzheimer’s plaques and preserving cognitive function in mice with memory issues.
- Astrocytes connect specific brain regions through plastic networks
A study published in Nature on April 22, 2026, reveals that astrocytes form plastic networks of gap junction-coupled cells to mediate communication between distant brain regions. The research highlights the role of these astrocytic networks in connecting specific brain areas.
- Newfound brain network is a ‘secret system’ made of helper cells
A new brain network composed of star-shaped astrocyte cells has been discovered, connecting distant brain regions and enabling long-distance molecular exchange. The study was published in the journal Nature on 22 April 2026.
- Scientists discover hidden brain switch that tells you to stop eating
Researchers found that astrocytes play a key role in controlling appetite by receiving signals from tanycytes after a meal and activating fullness neurons, potentially leading to new treatments for obesity and eating disorders.
- These overlooked brain cells may control fear and PTSD
Astrocytes, previously considered support cells in the brain, are now found to actively participate in fear memory formation and modulation, potentially leading to new treatments for anxiety disorders.
