项目摘要

Project 1: Abstract We have shown that DNRAb, antibodies that cross-react with DNA and N-methyl D-aspartate receptor, cause cognitive impairment when they penetrate the hippocampus. The neural injury proceeds in two stages. First, there is excitotoxic neuronal death; second, there is microglial activation and dendritic loss in surviving neurons. Microglial suppression by angiotensin converting enzyme (ACE) inhibition restores neuronal integrity and cognitive function. We propose now to study the mechanism of microglial activation and dendritic loss and the mechanism of action of ACE inhibition. These studies have the potential to suggest additional therapeutic targets for ameliorating cognitive impairment in neuropsychiatric lupus.

项目1：摘要我们已经证明了DNRAb，与DNA和N-甲基D-天冬氨酸交叉反应的抗体受体，当它们穿透海马体时会导致认知障碍。神经损伤收益分两个阶段进行。首先，是兴奋性神经元死亡；其次，是小胶质细胞。存活神经元的激活和树突丢失。血管紧张素对小胶质细胞的抑制作用转换酶(ACE)抑制可以恢复神经元的完整性和认知功能。我们现建议研究小胶质细胞激活和树突状细胞丢失的机制以及血管紧张素转换酶抑制的作用机制。这些研究有可能提出更多改善神经精神性狼疮患者认知功能障碍的治疗目标。
