Primary age-related tauopathy (PART) is a neurodegenerative pathology with features distinct from but also overlapping with Alzheimer disease (AD). While both exhibit Alzheimer-type temporal lobe neurofibrillary degeneration alongside amnestic cognitive impairment, PART develops independently of amyloid-β (Aβ) plaques. The pathogenesis of PART is not known, but evidence suggests an association with genes that promote tau pathology and others that protect from Aβ toxicity. Here, we performed a genetic association study in an autopsy cohort of individuals with PART (n = 647) using Braak neurofibrillary tangle stage as a quantitative trait. We found some significant associations with candidate loci associated with AD (SLC24A4, MS4A6A, HS3ST1) and progressive supranuclear palsy (MAPT and EIF2AK3). Genome-wide association analysis revealed a novel significant association with a single nucleotide polymorphism on chromosome 4 (rs56405341) in a locus containing three genes, including JADE1 which was significantly upregulated in tangle-bearing neurons by single-soma RNA-seq. Immunohistochemical studies using antisera targeting JADE1 protein revealed localization within tau aggregates in autopsy brains with four microtubule-binding domain repeats (4R) isoforms and mixed 3R/4R, but not with 3R exclusively. Co-immunoprecipitation in post-mortem human PART brain tissue revealed a specific binding of JADE1 protein to four repeat tau lacking N-terminal inserts (0N4R). Finally, knockdown of the Drosophila JADE1 homolog rhinoceros (rno) enhanced tau-induced toxicity and apoptosis in vivo in a humanized 0N4R mutant tau knock-in model, as quantified by rough eye phenotype and terminal deoxynucleotidyl transferase dUTP nick end-labeling (TUNEL) in the fly brain. Together, these findings indicate that PART has a genetic architecture that partially overlaps with AD and other tauopathies and suggests a novel role for JADE1 as a modifier of neurofibrillary degeneration.

全基因组关联研究和功能验证表明 JADE1 与 tau 蛋白病有关

原发性年龄相关性 tau 蛋白病 (PART) 是一种神经退行性病变,其特征不同于阿尔茨海默病 (AD),但也与之重叠。虽然两者都表现出阿尔茨海默型颞叶神经原纤维变性和遗忘性认知障碍,但 PART 的发展独立于淀粉样蛋白 -β (Aβ) 斑块。PART 的发病机制尚不清楚,但有证据表明与促进 tau 病理学的基因和其他保护免受 Aβ 毒性的基因有关。 在这里,我们使用 Braak 神经原纤维缠结阶段作为数量性状,对 PART 患者( n = 647)的尸检队列进行了遗传关联研究。我们发现与 AD 相关的候选基因座有一些显着关联(SLC24A4MS4A6AHS3ST1) 和进行性核上性麻痹(MAPTEIF2AK3)。全基因组关联分析揭示了与 4 号染色体 (rs56405341) 上包含三个基因的基因座中的单核苷酸多态性的新的显着关联,包括 JADE1,它在缠结神经元中被单胞体 RNA-seq 显着上调。使用针对 JADE1 蛋白的抗血清进行的免疫组织化学研究表明,尸检大脑中的 tau 聚集体定位于具有四个微管结合域重复 (4R) 亚型和混合 3R/4R,但不完全是 3R。死后人类 PART 脑组织的免疫共沉淀揭示了 JADE1 蛋白与四个缺乏 N 末端插入片段的重复 tau (0N4R) 的特异性结合。最后,击倒果蝇JADE1 同系物犀牛( rno ) 在人源化 0N4R 突变体 tau 敲入模型中增强了 tau 诱导的体内毒性和细胞凋亡,通过粗眼表型和果蝇大脑中的末端脱氧核苷酸转移酶 dUTP 缺口末端标记 (TUNEL) 进行量化。总之,这些发现表明 PART 具有与 AD 和其他 tau 病部分重叠的遗传结构,并表明 JADE1 作为神经原纤维变性调节剂的新作用。
