WebJun 29, 2024 · When neurons and glia are injured, intracellular neuroglial proteins are released into body fluids. Measurement of such proteins in CSF or blood can be used to detect and assess injury to the nervous system in neurological diseases and trauma, e.g. multiple sclerosis, amyotrophic lateral sclerosis, stroke and traumatic brain injury [1,2,3]. WebAfter an injury, protein is released into the CSF and through the arachnoid villi, crosses into the blood stream. The presence in plasma of this protein is an indication of both neuronal damage, as increased blood–brain barrier patency.
