In a surprising coincidence, two groups of researchers working from entirely different starting points have converged on a mutated gene involved in another aspect of Alzheimer’s disease: the immune system’s role in protecting against the disease. The mutation is suspected of interfering with the brain’s ability to prevent the buildup of plaque.
The discovery, researchers say, provides clues to how and why the disease progresses. The gene, known as TREM2, is only the second found to increase Alzheimer’s risk substantially in older people.
