神经性疼痛是一种慢性衰弱性疾病,其特征是机械性异常性疼痛和自发性疼痛。由于症状通常对传统的疼痛治疗方法没有反应,因此新的治疗方法至关重要。在这里,我们描述了一种策略,不仅可以改善神经性疼痛的症状,而且还可能改变疾病。我们发现,将小鼠内侧神经节隆起(MGE)的未成熟端脑 GABA 能中间神经元移植到成年小鼠脊髓中,可以完全逆转周围神经损伤产生的机械超敏反应。这一改进的基础是 MGE 移植物与宿主脊髓回路的显着整合,其中移植的细胞与初级传入神经元和脊髓神经元建立功能连接。相比之下,MGE 移植不能有效缓解炎性疼痛。我们的研究结果表明,MGE 衍生的 GABA 能中间神经元克服了脊髓过度兴奋,这是神经损伤引起的神经性疼痛的标志。
Neuropathic pain is a chronic debilitating disease characterized by mechanical allodynia and spontaneous pain. Because symptoms are often unresponsive to conventional methods of pain treatment, new therapeutic approaches are essential. Here, we describe a strategy that not only ameliorates symptoms of neuropathic pain, but is also potentially disease modifying. We show that transplantation of immature telencephalic GABAergic interneurons from the mouse medial ganglionic eminence (MGE) into the adult mouse spinal cord completely reverses the mechanical hypersensitivity produced by peripheral nerve injury. Underlying this improvement is a remarkable integration of the MGE transplants into the host spinal cord circuitry, in which the transplanted cells make functional connections with both primary afferent and spinal cord neurons. By contrast, MGE transplants were not effective against inflammatory pain. Our findings suggest that MGE-derived GABAergic interneurons overcome the spinal cord hyperexcitability that is a hallmark of nerve-injury induced neuropathic pain.
