IBS and Sungkyunkwan University identify a four-step astrocyte signaling pathway that sustains neural activity and vascular ...

What actually happens in the brain in cases of depression? Relatively unknown brain cells—"astrocytes"—are believed to play an important role. At the Uppsala Biomedical Center, lab researchers are ...

Researchers at Baylor College of Medicine have discovered a natural mechanism that clears existing amyloid plaques in the brains of mouse models of Alzheimer's disease and preserves cognitive function ...

Deep in the dentate gyrus of the hippocampus, a remarkable process continues throughout life: new neurons are born from ...

For more than a century, the story of the brain has been told as a tale of neurons, with every thought and memory traced to their electrical chatter. That narrative is now being rewritten as evidence ...

Astrocytes modulate neuronal activity by gliotransmission and through metabolic regulation, yet the relationship between these functions remains poorly understood ...

When astrocyte function is disrupted, neurons in the brain's motor cortex struggle to execute and refine motion, a new study in mice shows. From steering a car to swinging a tennis racket, we learn to ...

The potential effects of astrocyte dysfunction in neurodegenerative diseases are summarized in Figure 2. AD is characterized clinically by cognitive loss in two or more domains, including memory, ...

Researchers have uncovered novel aspects of astrocyte function in olfactory, or smell, perception revealing changes in their gene expression patterns that turn these brain cells into a hub of ...

Scientists have engineered a nanowire platform that mimics brain tissue to study astrocytes, the star-shaped cells critical for brain health, for the first time in their natural state. Astrocytes are ...

The link between Alzheimer’s disease and amyloid plaques is well documented, with innumerable studies exploring techniques and therapies to inhibit plaque formation, preventing development or ...
