An evolving form of therapy to treat devastating neurodegenerative disorders by injecting fresh immune cells—microglia—directly into the brain, promises a new lease on health by slowing the progression of mind-robbing conditions.

The research, underway in China, is in the pre-clinical phase of investigation and is aimed at protecting vital neurons, while at the same time, combating the early hallmarks of neurological disorders, such as Alzheimer’s disease.

So far, the microglia transplants have been performed in animal models, but they have ameliorated symptoms of neurological disease.
