Abstract

Wallerian degeneration following peripheral nerve transection in C57BL/Ola mice is very slow in comparison to other strains of mice. We show that following optic nerve transection, the axons of retinal ganglion cells in C57BL/Ola mice undergo very slow Wallerian degeneration and that retrograde degeneration of the ganglion cell bodies is much slower than in other strains of mice. The results suggest that the gene product affecting Wallerian degeneration in the peripheral nervous system (PNS) also confers a greater resistance to degeneration on central nervous system (CNS) neurons.
