人们对开发反映中枢神经系统组织损伤以确定预后的多发性硬化症(MS)生物标志物越来越感兴趣。我们旨在通过测量脑脊液 (CSF) 中 KIF5A 的水平并结合分析位于染色体 12q13-14 区域 MS 易感基因位点内的单核苷酸多态性(SNP;rs12368653 和 rs703842)来评估驱动蛋白超家族运动蛋白 KIF5A 在 MS 中的预后价值。使用酶联免疫吸附测定法测量从两个独立生物库获得的脑脊液中的 KIF5A,其中包括非炎症性神经疾病对照 (NINDC)、临床孤立综合征 (CIS) 和 MS 病例。与 NINDC、CIS 和复发缓解型 MS (RRMS) 相比,进行性 MS 病例中 CSF KIF5A 表达显着升高。此外,在 2 年临床随访中记录疾病进展的 RRMS 患者中,KIF5A 水平与 MS 疾病严重程度评分(EDSS、MSSS 和 ARMSSS)的变化呈正相关。腺嘌呤风险等位基因(AG/AA;rs12368653 和 rs703842)的副本与腰椎穿刺 (LP) 时复发的个体比例较高、LP 后疾病缓解疗法的使用率较高以及 MS 持续时间较短相关。我们的研究表明,CSF KIF5A 有潜力作为 MS 的预测生物标志物,应考虑进一步研究分析 MS 易感性 SNP 的潜在预后价值。本文的在线版本 (10.1007/s00415-020-10373-w) 包含补充材料,可供授权用户使用。
There is increasing interest in the development of multiple sclerosis (MS) biomarkers that reflect central nervous system tissue injury to determine prognosis. We aimed to assess the prognostic value of kinesin superfamily motor protein KIF5A in MS by measuring levels of KIF5A in cerebrospinal fluid (CSF) combined with analysis of single nucleotide polymorphisms (SNPs; rs12368653 and rs703842) located within a MS susceptibility gene locus at chromosome 12q13–14 region. Enzyme-linked immunosorbent assay was used to measure KIF5A in CSF obtained from two independent biobanks comprising non-inflammatory neurological disease controls (NINDC), clinically isolated syndrome (CIS) and MS cases. CSF KIF5A expression was significantly elevated in progressive MS cases compared with NINDCs, CIS and relapsing–remitting MS (RRMS). In addition, levels of KIF5A positively correlated with change in MS disease severity scores (EDSS, MSSS and ARMSSS), in RRMS patients who had documented disease progression at 2-year clinical follow-up. Copies of adenine risk alleles (AG/AA; rs12368653 and rs703842) corresponded with a higher proportion of individuals in relapse at the time of lumbar puncture (LP), higher use of disease-modifying therapies post LP and shorter MS duration. Our study suggests that CSF KIF5A has potential as a predictive biomarker in MS and further studies into the potential prognostic value of analysing MS susceptibility SNPs should be considered.
