New research suggests the brain and immune system are linked via the lymphatic system, which could provide new insights into certain neurological disorders.

Lymphatic System

Scientists have long known about the body’s ability to drain waste via its lymphatic vessels, also known as the body’s “sewer system.” Blood vessels transport white blood cells to organs, while the lymphatic system removes these cells, along with waste, and recirculates them. This helps the immune system notice if part of the body is under attack from viruses or bacteria, or has been injured. New studies have uncovered evidence that the brain also uses these vessels.

According to director of the National Institute of Neurological Disorders and Stroke (NINDS), this research “could fundamentally change the way we think about how the brain and immune system inter-relate.”
