Astrocytes (IMAGE)
Caption
Using a combination of advanced genetic analysis and high-resolution microscopy, scientists have identified a distinct subtype of brain support cells—astrocytes enriched in the protein cadherin-4 (CDH4), shown in magenta. These cells seem to protect nerve cells against cell death. In Alzheimer’s disease, this group of cells becomes less abundant, but exercise seems to strengthen them. In the image, astrocytes are shown in orange, blood vessels in green, and cell nuclei in blue. Image credit: Luis Moreira.
