Astrocytes Actively Dictate Long-Term Memory Persistence

By leveraging ankyrin-2 (Ank2) to regulate BDNF/TrkB.T1 calcium signaling, astrocytes undergo structural remodeling to physically encapsulate and stabilize memory-storing engram neurons, a mechanism validated through a novel optogenetic tool called Opto-T1.

Astrocytes, Not Neurons, Hold the Key to Emotional Memory

New research reveals that astrocytes — not neurons — are responsible for stabilizing emotional memories by re-engaging during recall. After an emotionally intense event, such as fear, specific astrocytes become biologically tagged with adrenoreceptors, making them responsive when the memory is later reactivated.

Infant Brain Gene Regulator May Predispose Adults to Dementia

A new study reveals that the brain’s vulnerability to disorders like multiple sclerosis and dementia may begin in early life. Researchers identified a developmental “switch” in astrocytes, the brain’s support cells, governed by the NR3C1 gene.
