Animation of microglia cells (pink) in the brain of a person with Alzheimer's disease. Microglia are the main type of immune system cell in the brain. In healthy people they destroy invading pathogens and clean up dead cells. In Alzheimer's disease, the microglia secrete excess amounts of interleukin-1, an immunoregulatory chemical, which aids the formation of the amyloid plaques (orange) and neurofibrillary tangles (blue) that cause the symptoms of the disease. | |
