Discovery Reveals Aging Human Brains Receive Immune Cell Reinforcements From Blood

Scientists discover a hidden brain shift that begins around age 50

Beginning around age 50, the brain’s memory center appears to lose many of its longtime immune cells and replace them with more inflammatory ones. This surprising shift may help explain how normal aging sets the stage for Alzheimer’s disease and dementia.

Stanford Finds the Aging Brain Is Not Sealed off from the Body, Overturning a Long-Held Assumption

Stanford researchers found blood-derived immune cells enter the aging human brain, challenging the idea that it is immunologically sealed. What it means.

Discovery reveals aging human brains receive immune cell reinforcements from blood

The brain's immune system has long been thought to exist independently from the rest of the body, complete with its own specialized immune cells and a blood-brain barrier that limits what can travel into the brain.
