In the present note we have investigated the cytochemical localization of acetylcholinesterase (AChE) in the chick ciliary ganglion (CG) after post-ganglionic axotomy obtained by ablation of the eyeball. Preliminary results show at quite early stages after axotomy a remarkable reduction of cytoplasmic AChE, the residual one being localized in the rough endoplasmic reticulum. On the contrary synaptic areas, in particular those concerning the calyciform synapses, still show a marked AchE activity, similarly to what observed in physiological conditions. The decrease of cytoplasmic AChe in axotomized CG does suggest the possibility that such AChE undergoes to a topographical rearrangement moving towards the synaptic areas of ganglionic neurons.

Abstract

In the present note we have investigated the cytochemical localization of acetylcholinesterase (AChE) in the chick ciliary ganglion (CG) after post-ganglionic axotomy obtained by ablation of the eyeball. Preliminary results show at quite early stages after axotomy a remarkable reduction of cytoplasmic AChE, the residual one being localized in the rough endoplasmic reticulum. On the contrary synaptic areas, in particular those concerning the calyciform synapses, still show a marked AchE activity, similarly to what observed in physiological conditions. The decrease of cytoplasmic AChe in axotomized CG does suggest the possibility that such AChE undergoes to a topographical rearrangement moving towards the synaptic areas of ganglionic neurons.
