丝裂原活化蛋白激酶在糖尿病神经病理性疼痛中枢敏化和外周敏化中作用的研究进展

Research Advances in Mitogen-activated Protein Kinases in Central and Peripheral Sensitization of Diabetic Neuropathic Pain

丝裂原活化蛋白激酶(MAPKs)是一组包括细胞外信号调节激酶1/2、c-Jun氨基端激酶1/2/3、p38亚型(α,β,γ和δ)和细胞外信号调节激酶5的丝/苏氨酸蛋白激酶,能够介导增殖、分化、凋亡、免疫、炎症等一系列细胞活动。痛觉敏化是一种中枢和外周伤害性感受器的重塑机制。大量研究显示,MAPKs在糖尿病动物模型的脊髓和背根神经节中广泛激活,在糖尿病神经病理性疼痛(DNP)中枢敏化和外周敏化中发挥了重要的作用。此外,一些药物也可通过抑制中枢和外周神经系统中MAPKs的激活来缓解DNP。本文主要总结了MAPKs在DNP中枢和外周敏化中作用的研究进展。

Mitogen-activated protein kinases(MAPKs)are Ser/Thr kinases consisting of extracellular regulated protein kinases(ERK)1/2,c-Jun N-terminal kinase 1/2/3,p38 isoforms(α,β,γ,andδ),and ERK5,which mediate a range of cellular activities including proliferation,differentiation,apoptosis,immunity,and inflammation.Pain sensitization is a remodeling mechanism of central and peripheral nociceptor.A growing number of evidences have indicated that MAPKs are extensively activated in the spinal dorsal cord and dorsal root ganglions in the animal models of diabetic neuropathic pain(DNP)and play an important role in the central and peripheral sensitization of DNP.In addition,some drugs can alleviate DNP by suppressing MAPKs activation of central and peripheral nervous system.This article summarizes the research progress of MAPKs in central and peripheral sensitization of DNP.
