New Drug Targets Brain Glial Cells to Reverse PTSD Symptoms

A new study reveals that astrocyte-derived GABA, not neuronal activity, plays a central role in PTSD by impairing the brain’s ability to extinguish traumatic memories. Researchers found this excess GABA originates from the enzyme MAOB in astrocytes and disrupts fear regulation in the medial prefrontal cortex.

This illustrates how astrocytes assist in GABA neurotransmission.

Synaptic Tau and Astrocytes Drive PSP Progression

ew research uncovers how tau pathology spreads and damages synapses in progressive supranuclear palsy (PSP). Using human postmortem tissue and live brain slice models, scientists showed tau accumulates in both pre- and postsynaptic terminals, likely propagating neuron-to-neuron.

Exercise Rewires Alzheimer’s-Affected Brain Cells

Using cutting-edge RNA sequencing, researchers mapped how exercise affects specific brain cell types in a model of Alzheimer’s disease. They found that physical activity alters gene activity in microglia and a newly identified type of astrocyte linked to blood vessels, which may protect memory.

Astrocytes May Hold the Key to Brain’s Vast Memory Capacity

New research proposes that astrocytes—long thought to be merely supportive cells—may significantly enhance the brain’s ability to store memories. Unlike neurons, astrocytes cannot fire electrical signals but can influence synaptic activity through calcium signaling and gliotransmitters.

Astrocytes Control Behavior Through Slow Brain Signaling

Astrocytes, once thought to be mere support cells, are now shown to play a leading role in regulating behavior by modulating neuronal activity through slow biochemical circuits. In zebrafish, researchers discovered that astrocytes respond to norepinephrine by releasing ATP, which is then broken down into adenosine—an important neuromodulator that signals neurons to stop swimming when progress is futile.

Astrocytes Take Center Stage in Brain Function and Behavior

Long thought to be mere support cells, astrocytes are now shown to play a powerful, dynamic role in regulating brain function and behavior. New research in fruit flies and rodents reveals that astrocytes don’t just support neurons—they selectively respond to neurotransmitters and influence which neural signals are prioritized.

Astrocytes, Not Neurons, Drive Brain’s Attention and Alertness

For nearly a century, scientists believed that neuromodulators like norepinephrine adjusted brain communication by acting directly on neurons. A new study overturns this long-held view, revealing that astrocytes—support cells long considered secondary—are the key intermediaries.

Unlocking Spinal Cord Regeneration: Astrocytes Lead the Way

Spinal cord injuries (SCI) are challenging to treat due to the limited regenerative capacity of the central nervous system. A new study reveals that while ependymal cells in the spinal cord show minimal repair potential, astrocytes can transdifferentiate into oligodendrocytes, aiding in remyelination.

Astrocytes Hold the Key to Stress Response Regulation

Astrocytes, previously known for supporting nerve cells, have been identified as key regulators of stress responses in the lateral septum of the brain. Researchers demonstrated that astrocytes release adenosine to suppress nearby nerve activity when exposed to stress-inducing stimuli. This groundbreaking finding reveals that astrocytes interact dynamically with neurons to influence fear, anxiety, and social behaviors, varying based on the stress type and brain region.
