The study examined the brains of two types of mice: normal mice and mice with Alzheimer's disease. The mice were exposed to purified air or very small particles in the air. The researchers wanted to see if there were any changes in a type of brain cell called astrocytes. The astrocytes were stained green in the images, and the harmful and activated astrocytes appeared red. The merged images showed that the harmful astrocytes were more prevalent in the brains of the Alzheimer's mice exposed to the small particles. This suggests that exposure to these particles can activate harmful astrocytes in the brains of mice with Alzheimer's disease.
