Wallerian Degeneration and Clearance of Olfactory Receptor Neuron Axons following

Neurons extend their axons and dendrites over long distances and rely on evolutionarily conserved mechanisms to maintain the cellular structure and function of neurites at a distance from their cell body. Neurites that lose connection with their cell body following damage or stressors to their cytoskeleton undergo a programmed self-destruction process akin to apoptosis but using different cellular machinery, termed Wallerian degeneration. While first described for vertebrate axons by Augustus Waller in 1850, key discoveries of the enzymes that regulate Wallerian degeneration were made through forward genetic screens in
