Scientists discover whole new layer of brain tissue that may help ward off infections
Abnormalities in this layer may trigger or worsen multiple sclerosis, brain infections and Alzheimer’s
Scientists have discovered a while new layer of tissues in the brain that acts as a protective barrier and also as a platform from which immune cells monitor the brain for infection and inflammation.
The research, published in the journal Science on Thursday, assessed membranes that encase the brain and keep it bathed in CSF – a colourless body fluid that surrounds the brain and spinal cord, cushioning them from sudden impact or injury.
Until now, research has shown that there are three layers of membranes known as meninges that protect the brain and spinal cord – the dura, arachnoid and pia matter.
