"A new study from Weizmann Institute researchers has found evidence of a unique signature that may be the missing link between cognitive decline and aging. The scientists believe that this discovery will lead to future treatments that can slow or reverse cognitive decline in older people.
Until a decade ago, scientific dogma held that the blood-brain barrier prevents the blood-borne immune cells from attacking and destroying brain tissue. Yet in a long series of studies, the group showed that the immune system actually plays an important role both in healing the brain after injury and in maintaining the brain’s normal functioning. They found that this ‘brain-immune’ interaction occurs across a barrier that is actually a unique interface within the brain’s territory."
