  • Changes in axonally transported phospholipids of regenerating goldfish optic nerve were studied by intraocular injection of [2-3H]glycerol 9 days and 16 days after nerve crush at 30 degrees C. The four major glycerophospholipids all showed substantial increases in transported radioactivity above non-regenerating controls at both time points, these being maximal (15- to 35-fold) in the optic nerve-tract at 9 days and about half as great at 16 days. In the contralateral optic tectum transported label increased 6- to 13-fold at 9 days and 10- to 25-fold at 16 days in the various glycerophospholipids. While all glycerophospholipids showed absolute increases in both tissues, PS and PI increased relatively more, especially in the tectum. The regeneration-associated increases in transported label of all glycerophospholipids were larger than those previously demonstrated for gangliosides and glycoproteins in the same system.
