Abstract

Biochemical and ultrastructural studies of ceramide galactosyltransferase (CGT) in a CGT-deficient mouse line (cgt-/-) were complemented by nerve conduction velocity (NCV) measurements in motor nerves (sciatic nerve in the hind limbs) of wild type (wt) and cgt-/- mice. Stimulation and recording electrodes were adapted to the small size of developing mice during their myelination period. Motor NCVs in wt mice ranged between 16 and 26 m/s but in cgt-/- mice between 6 and 13 m/s, which corresponds to the conductance of unmyelinated peripheral nerves. These electrophysiologic data provide additional functional parameters to the neuropathology of a new form of a dysmyelinosis.
