Ischaemia damages nerve myelin by depriving neurons and their myelinating oligodendrocytes of oxygen and glucose; here it is shown that ischaemic damage is caused through the H+-dependent activation of TRPA1 channels, and not via glutamate receptors of the NMDA type, as previously thought, providing a new mechanism and promising therapeutic targets for diseases as diverse and prevalent as cerebral palsy, spinal cord injury, stroke and multiple sclerosis.
