A research team from the City University of New York published a study in the latest issue of 'Neuron', revealing the key mechanism between brain cell stress and the progression of Alzheimer's disease. This study focuses on the brain's main immune cells—the microglia. They serve as the 'first responders' in protecting brain health, but may also contribute to the exacerbation of neurodegeneration. This groundbreaking result indicates that drug therapies may be able to slow down or even reverse the disease.
