摘要
背景:偏头痛是一种高度致残的神经血管性原发性头痛疾病,其确切的病理机制仍未被揭示。 目前的主要假设是基于三叉神经血管系统的敏化和激活。 目的:重点研究犬尿氨酸(L-型犬尿氨酸和犬尿烯酸)和垂体腺苷酸环化酶活化多肽对三叉神经血管系统调控的影响。 方法:通过在MEDLINE / PubMed数据库中使用关键词“犬尿氨酸”,“垂体腺苷酸环化酶激活多肽”和“偏头痛”进行文献检索,以查明截至2016年9月10日临床前和临床出版物(198篇参考文献)的专题审查。 使用的其他筛选词包括“审查”,“系统评价”,“原始文章”和“英语”。 结果:L-型犬尿氨酸和犬尿烯酸对三叉神经核中二级伤害性神经元水平的谷氨酸能系统起作用。 垂体腺苷酸环化酶激活多肽从三叉神经假性神经元的周围神经末梢释放并引起血管舒张和肥大细胞脱粒,导致硬脑膜伤害感受器的周围致敏。 垂体腺苷酸环化酶激活多肽在三叉神经尾核中心释放导致二级神经元的中枢敏化。 致敏过程导致偏头痛的特征。 结论:L-型犬尿氨酸和犬尿烯酸和垂体腺苷酸环化酶活化多肽可能在最初偏头痛发作中发挥重要作用。

摘要: Background: Migraine is a highly disabling neurovascular primary headache disorder, with its exact pathomechanism being still unrevealed. The current leading hypotheses are based on the sensitization and activation of the trigeminovascular system.
Objective: To review the literature with focus on the effects of kynurenines (L-kynurenine and kynurenic acid) and pituitary adenylate cyclase-activating polypeptide on the regulation of the trigeminovascular system. Method: A literature search was conducted to identify preclinical and clinical publications (198 references) by using the keywords ‘kynurenines’, ‘pituitary adenylate cyclase-activating polypeptide’, and ‘migraine’ in the database of MEDLINE/PubMed up to 10 September 2016 for topical review. Additional filters used included ‘review’, ‘systematic review’, ‘original article’, and ‘English language’. Results: L-kynurenine and kynurenic acid act on the glutamatergic system at the level of the second-order nociceptive neurons in the trigeminal nucleus caudalis. Pituitary adenylate cyclase- activating polypeptide is released from the peripheral nerve endings of the trigeminal pseudounipolar neurons and causes vasodilation and mast cell degranulation, leading to consequent peripheral sensitization of the dural nociceptors. Centrally released pituitary adenylate cyclase-activating polypeptide in the trigeminal nucleus caudalis results in the central sensitization of the second-order neurons. The sensitization process leads to the characteristic features of migraine. Conclusion: L-kynurenine, kynurenic acid, and pituitary adenylate cyclase-activating polypeptide may have fundamental roles in the initiation of migraine headache attacks.Export Options
