Following permanent transection of their peripheral axons, a proportion of adult rat dorsal root ganglion neurons undergo programmed cell death (apoptosis) over a period of months. The underlying causes of this neuron loss are unclear, but may involve the interruption of the supply of target-derived neurotrophic factors, the replacement of which could prevent this loss from occurring. To investigate whether the administration of neurotrophic factors can prevent the dorsal root ganglion neuron death in adults, a 1 mg/ml solution of ciliary neurotrophic factor or of NT-3 was applied via a silicon reservoir to the proximal stump after unilateral sciatic transection at mid-thigh level. The incidence of apoptotic neurons and neuronal loss in the L4 and L5 ganglia ipsilateral to sciatic nerve transection when compared with the contralateral ganglia was then measured 1 month later. This was assessed by examining serial sections of ganglia for neurons undergoing apoptosis and expressing the total counted as a percentage of the total number of neurons estimated using a stereological neuron counting technique. Our results show that NT-3 administration significantly reduced the incidence of apoptotic neurons and prevented neuron loss, while CNTF had no effect on either parameter.
