Sky of the Brain
Tau proteins are found in the brain and usually have a role in giving stability to brain cells. But altered forms of tau can build up and clump together, forming "tangles" in the brain that researchers think are linked to dementia.
This image, titled Sky of the Brain, was the Under the Lens category winner in the Alzheimer’s Society’s 2022 Spotlight on Dementia research image competition.
The green spots in this image are mutant human tau proteins, generated in a mouse brain, in an area known to be affected by dementia in a human brain. The markers used to color the brain cells (yellow, red, blue) give an impression of constellations of stars around the Milky Way in the sky rather than proteins in the brain.
