Electron Microscopic Image of Nerves (image) Max-Planck-Gesellschaft Share Print E-Mail Caption These are electron microscopic images of cross sections of nerves in a healthy rat (left), a rat suffering from CMT1A (centre) and a rat suffering from CMT1A that has been treated with neuregulin-1 (right). The neuregulin-1 treatment leads to improved myelination in the CMT1A rat model, which comes close to that of healthy animals. Credit Fledrich et al, Nat.
