When a nerve is damaged, glial cells produce the protein
neuregulin1 and thereby promote the regeneration of nerve tissue
Unlike the brain and spinal cord, the peripheral nervous
system has an astonishing capacity for regeneration following injury.
Researchers at the Max Planck Institute of Experimental Medicine in Göttingen
have discovered that, following nerve damage, peripheral glial cells produce
the growth factor neuregulin1, which makes an important contribution to the
regeneration of damaged nerves.
