摘要:

背景 Ephs受体是人类基因组中受体型酪氨酸蛋白激酶(receptor tyrosine kinase,RTKs)中最大的亚家族,与其配体Ephrins结合参与组织边缘形成、血管再生、轴突导向及突触可塑性等诸多生长发育过程。近年来研究发现EphrinBs/EphBs信号系统参与调控了疼痛的发生和维持。目的 回顾和总结EphrinBs/EphBs调控疼痛的机制。内容 大量研究证明EphrinBs/EphBs信号系统的激活可能通过上调伤害性脊神经节和脊髓后角的广动力范围型神经元兴奋性,诱导中枢致敏,以及活化下游丝裂原活化蛋白激酶(mitogen-activated protein kinase,MAPKs)通路参与了伤害性信息的调制。趋向 明晰EphrinBs/EphBs信号系统参与疼痛过程的下游机制,有助于发现临床上治疗疼痛的新靶点。

Abstract:

Background Ephs is the largest subfamily of receptor tyrosine kinases(RTKs) in the human genome, which binds to the ligand, Ephrins, to regulate many development processes, including tissue-border formation, re-angiogenesis, axon guidance, and synaptic plasticity. Recent studies indicate that EphrinBs/EphBs signaling regulates the nociceptive process. Objective Here we retrospectively summarized the mechanism of EphrinBs/EphBs signaling pathway in regulating the process of pain. Content A great deal of studies have shown that EphrinBs/EphBs signaling pathway modulates the development of nociceptive process through upregulating the excitability of nociceptive dorsal root ganglia and wide dynamic range neurons in spinal dorsal horn, producing central sensitization, and activating the downstream mitogen-activated protein kinase (MAPKs) pathway. Trend Clarifying the downstream mechanism of EphrinBs/EphBs signaling pathway in the nociceptive process will be helpful helpful to find a new potential target for the treatment of pain.
