Pain and NMDA Receptor<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /> 王景阳 教授 ABSTRACT Accumulating evidences implicate the importance of N-methyl-D-Aspartate (NMDA) receptors in the induction and maintenance of central sensitization during pain states. NMDA receptors are composed of NR1, NR2(A, B, C and D) subunits, which determine the functional properties of NMDA receptors subunit. The NR2B appears particularly important for nociception. It is possible that NR2B-seletive antagonists may be useful in the treatment of chronic pain.
过去几十年来,在生物医学领域内,NMDA受体拮抗剂可谓是最热门的研究课题之一。1980年后期有研究指出,脊髓释放NMDA受体(N-methyl-D-aspartate receptor, NMDAR)拮抗剂,可抑制刺激C纤维导致脊髓感受伤害神经元的过度兴奋[1]。嗣后,数以百计的文献强调组织损伤和炎症后NMDAR激活可促进以上导致过度兴奋的过程。 |
