双相情感障碍(BD)认知能力下降、症状恶化和脑萎缩的报告表明,这种疾病会随着时间的推移而进展。神经病理学恶化可能涉及兴奋性毒性和神经炎症。我们测定了 10 名 BD 患者和 10 名年龄匹配的对照者死后额叶皮质中兴奋性毒性和神经炎症标志物的蛋白质和 mRNA 水平。脑组织的年龄、死后间隔和 pH 值相匹配。结果表明,NMDA 受体、NR-1 和 NR-3A 的蛋白质和 mRNA 水平显着降低,但 IL-1β、IL-1 受体、骨髓分化因子 88 (MyD88)、核因子 Kappa B 亚基以及星形胶质细胞和小胶质细胞标记物(胶质纤维酸性蛋白 (GFAP)、诱导型硝酸盐)的蛋白质和 mRNA 水平显着升高。 与对照受试者相比,BD 死后额叶皮质中的氧化物合酶(iNOS))、c-fos 和 CD11b)。同一区域肿瘤坏死因子α(TNFα)或神经元nNOS的mRNA水平没有显着差异。这些数据表明 BD 额叶皮质中存在兴奋性毒性和神经炎症,特别是 IL-R 级联的激活。这些变化可能解释了 BD 疾病进展的报道证据,并成为未来治疗的目标。
Reports of cognitive decline, symptom worsening and brain atrophy in bipolar disorder (BD) suggests that the disease progresses over time. The worsening neuropathology may involve excitotoxicity and neuroinflammation. We determined protein and mRNA levels of excitotoxicity and neuroinflammatory markers in postmortem frontal cortex from 10 BD patients and 10 age-matched controls. The brain tissue was matched for age, postmortem interval and pH. The results indicated statistically significant lower protein and mRNA levels of the NMDA receptors, NR-1 and NR-3A, but significantly higher protein and mRNA levels of IL-1β, the IL-1 receptor, myeloid differentiation factor 88 (MyD88), nuclear factor-kappa B subunits and astroglial and microglial markers (glial fibrillary acidic protein (GFAP), inducible nitric oxide synthase (iNOS)), c-fos and CD11b) in postmortem frontal cortex from BD compared with control subjects. There was no significant difference in mRNA levels of tumor necrosis factor alpha (TNFα) or neuronal nNOS in the same region. These data demonstrate the presence of excitotoxicity and neuroinflammation in BD frontal cortex, with particular activation of the IL-R cascade. The changes may account for reported evidence of disease progression in BD, and be a target for future therapy.
