Specific immune cells in the brain may play a crucial role in preventing the onset of Alzheimer's disease, according to a new study – a discovery that could lead to new therapies that try to coax cells into this protective state.
Earlier studies have shown that immune cells in the brain called microglia can effectively tackle the symptoms of Alzheimer's, but also make them worse through inflammation.
Here, an international team of scientists took a detailed look at how microglia switch between those two helpful and harmful modes.
