成年外周神经元在轴突损伤后可以再生。在这些轴突切断的神经元的细胞体中,基因表达发生了很大的变化,包括用于突触传递的一些蛋白质的表达减少,以及参与再生的一些蛋白质的表达增加。触发这些变化的信号才刚刚开始被阐明。切断交感、感觉和运动神经元的一个特征是它们增加了两种神经肽--血管活性肠肽和甘丙肽的表达。这些多肽可能在失去靶源性营养因子的轴突切断神经元的存活和再生中发挥重要作用。最近的研究表明,在交感神经元诱导这些多肽的过程中有两个重要的信号:一个是损伤神经元附近的非神经细胞释放白血病抑制因子(LIF);另一个是靶源性神经生长因子(NGF)的去除。此外,在这两个事件之间存在协同作用,通过去除NGF改变神经元对LIF的反应性。未来的努力有望确定LIF和NGF在多大程度上向细胞体反应的其他方面发出信号,以及这些作用背后的机制。神经科学家3:176-185,1997
Adult peripheral neurons can regenerate after axonal damage. Large changes in gene expression occur in the cell bodies of these axotomized neurons, including decreases in expression of a number of proteins used for synaptic transmission and increases in expression of a number of proteins involved in regeneration. The signals that trigger these changes are just beginning to be elucidated. One characteristic of axotomized sympathetic, sensory, and motor neurons is that they increase expression of two neuropeptides, vasoactive intestinal peptide and galanin. These peptides may play important roles in the survival and regeneration of axotomized neurons deprived of their target-derived trophic factors. Recent studies have demonstrated two important signals in the induction of these peptides in sympathetic neurons: one is the release of leukemia inhibitory factor (LIF) by non-neuronal cells in the vicinity of the injured neurons and the other, the removal of target-derived nerve growth factor (NGF). Furthermore, there is a synergistic interaction between these two events whereby the removal of NGF alters the responsiveness of neurons to LIF. Future efforts will hopefully determine the extent to which LIF and NGF signal other aspects of the cell body response and the mechanisms that underlie these actions. NEUROSCIENTIST 3:176-185, 1997
