Bagged in three layers of meninges and selectively fenced off by the blood brain barrier, our central nervous system (CNS) interacts within strict limits with our immune system. Protective ...

Scientists have long believed that the pia, the innermost of the three meningeal membranes that surround the brain, is impermeable to cerebrospinal fluid. But the pia has been hard to study. This ...

Cerebrospinal fluid washes waste from the brain, eventually draining into the lymph nodes and bloodstream—but exactly how this flow bypasses the brain’s barriers to reach the periphery has remained ...

Research by scientists at the University of Virginia (UVA) and Virginia Tech suggests that boosting the flow of fluid and macromolecules through a series of recently discovered lymphatic channels in ...

Leptomeningeal metastases (LM) occur when cancerous cells metastasize or spread to the leptomeninges, cerebral spinal fluid (CSF), or both. The meninges are thin layers of tissue surrounding and ...

Some long-term effects of meningitis might begin to become apparent during the acute phase of the condition due to brain or nerve damage—and these symptoms often persi ...

Cerebrospinal fluid, or CSF, is a clear, colorless liquid that plays a crucial role in maintaining the health and function of your central nervous system. It cushions the brain and spinal cord, ...
