Title: [Molecular forms of acetylcholinesterase in the chicken ciliary ganglion; changes after denervation, axotomy and double section] Couraud JY, Koenig H, Di Giamberardino L Ref: Comptes Rendus de l Academie des Sciences, 288:1199, 1979 : PubMed
Four main molecular forms of acetylcholinesterase (AChE), with sedimentation coefficients of 5, 7.5, 11.5 and 20 S, are found in Chicken ciliary ganglion. After denervation, the loss in 11.5 and 20 S forms occuring in 48 hrs coincides with the disappearance of presynaptic structures. In contrast, axotomy induces an early and durable increase in 7.5 S form. From these results, it is inferred that 11.5 and 20 S forms are predominant in presynaptic structures and 7.5 S form is mainly postsynaptic. In addition, the effects observed after simultaneous denervation and axotomy show a reciprocal control between pre- and postsynaptic elements. Finally, a trans-synaptic effect is exerted on 20 S AChE in controlateral ganglion after preganglionic sections.
