Golgi staining has revealed that ectopic neurites sprout from the axon-hillock region of cortical pyramidal neurons in kittens with swainsonine-induced α-mannosidosis. These new growth processes appeared qualitatively identical to those reported in a variety of inherited neuronal storage diseases including the gangliosidoses. In the latter, such processes have been shown to be dendritic-like and postsynaptic to afferents of unknown origin. We believe this to be the first demonstration of induced dendritogenesis in the mammalian CNS and a model system which should prove useful in exploring this remarkable phenomenon occurring in neuronal storage disorders.
