摘要
疼痛已成为一大社会和临床问题,由于目前的治疗没有提供足够缓解疼痛的方法。疼痛受体的可塑性与感觉神经元的敏感性和非神经细胞释放的可溶性介质一起阻碍了我们掌控疼痛发展的空间和时间尺度、神经元的反应和疾病的进展。在病理条件下, ATP是激活P2X受体最有力的介质之一,P2X受体类似于ATP检测器,例如神经元P2X3受体亚型和P2X4和P2X7受体上表达非神经元细胞。仔细分析感觉神经元和在辅助细胞中发生的分子机制,为设计适当组织-细胞- 靶向方法来治疗慢性疼痛提供了可能。

摘要: Pain represents a very large social and clinical problem since the current treatment provides insufficient pain relief. Plasticity of pain receptors together with sensitisation of sensory neurons, and the role of soluble mediators released from non-neuronal cells render difficult to understand the spatial and temporal scale of pain development, neuronal responses and disease progression. In pathological conditions, ATP is one of the most powerful mediators that activates P2X receptors that behave as sensitive ATP-detectors, such as neuronal P2X3 receptor subtypes and P2X4 and P2X7 receptors expressed on non-neuronal cells. Dissecting the molecular mechanisms occurring in sensory neurons and in accessory cells allows to design appropriate tissue- and cell- targeted approaches to treat chronic pain.
