Immune cells in the meninges come from bone marrow in the skull and migrate to the brain through special channels without passing through the blood. These immune cells help to guard the brain and spinal cord against inflammation and infection.
Spinal cord injuries cause stem cells in the bone marrow to rapidly divide. Following the cell division, the stem cells become trapped in the bone marrow.
Researchers report transplanting bone marrow from young mice to older mice helps to preserve memory and learning skills. If the findings can be replicated in humans, researchers believe new therapies can be devised to help combat disorders associated with brain aging.
A new study reveals the intestine as a source of immune cells that help reduce neuroinflammation in patients with multiple sclerosis. Increasing the number of these cells helps block inflammation entirely, researchers report.
A new study reports those who suffered disabilities as a result of stroke demonstrated substantial long term recovery following stem cell transplantation.
Researchers have been able to preserve cognition in mice exhibiting features of Alzheimer's disease.
