Figure 4.

Sensory axon degeneration in KIF5A null /KIF5Aflox; Cresynapsin mutant mice. (A) Ventral roots of 3-wk-old and 5.5-mo-old mutant mice. Note the lack of degeneration. Bar, 50 μm. (B) Dorsal roots of 3-wk-old and 5.5-mo-old mutant mice. Note the lack of degeneration in 3-wk sensory axons, but in the 5.5-mo-old mutant, there are large numbers of degenerating axons (arrowheads) and a striking decrease of large caliber axons. Bar, 20 μm.
