TAR DNA 结合蛋白 43 (TDP-43) 是肌萎缩侧索硬化症 (ALS) 的致病因素。神经元中细胞质 TDP-43 聚集是 ALS 的标志性病理学。在各种应激条件下,TDP-43依次定位于两种细胞质蛋白聚集体,即首先是应激颗粒(SG),然后是聚集体。越来越多的证据表明,TDP-43 阳性 SG 的延迟清除与 ALS 中的病理性 TDP-43 聚集有关。我们发现,泛素特异性蛋白酶 10 (USP10) 促进蛋白酶体抑制剂处理的细胞中 TDP-43 阳性 SG 的清除,从而促进 TDP-43 阳性聚集体的形成,并且 USP10 的消耗增加了细胞中不溶性 TDP-35(TDP-43 的裂解产物)的量。 细胞质。 TDP-35以RNA结合依赖性方式与USP10相互作用;然而,TDP-35 的 RNA 结合受损减少了 SG 和聚集体的定位,并诱导 USP10 阴性 TDP-35 聚集。免疫组织化学显示,ALS患者神经元中大部分细胞质TDP-43/TDP-35聚集体均为USP10阴性。我们的研究结果表明,USP10 通过促进 TDP-43/TDP-35 阳性 SG 的清除并促进 TDP-43/TDP-35 阳性聚集体的形成来抑制神经元细胞细胞质中 TDP-43/TDP-35 的异常聚集。
TAR DNA-binding protein 43 (TDP-43) is a causative factor of amyotrophic lateral sclerosis (ALS). Cytoplasmic TDP-43 aggregates in neurons are a hallmark pathology of ALS. Under various stress conditions, TDP-43 localizes sequentially to two cytoplasmic protein aggregates, namely, stress granules (SGs) first and then aggresomes. Accumulating evidence suggests that delayed clearance of TDP-43-positive SGs is associated with pathological TDP-43 aggregates in ALS. We found that ubiquitin-specific protease 10 (USP10) promotes the clearance of TDP-43-positive SGs in cells treated with proteasome inhibitor, thereby promoting the formation of TDP-43-positive aggresomes, and the depletion of USP10 increases the amount of insoluble TDP-35, a cleaved product of TDP-43, in the cytoplasm. TDP-35 interacted with USP10 in an RNA-binding-dependent manner; however, impaired RNA binding of TDP-35 reduced the localization in SGs and aggresomes and induced USP10-negative TDP-35 aggregates. Immunohistochemistry showed that most of the cytoplasmic TDP-43/TDP-35 aggregates in the neurons of ALS patients were USP10 negative. Our findings suggest that USP10 inhibits aberrant aggregation of TDP-43/TDP-35 in the cytoplasm of neuronal cells by promoting the clearance of TDP-43/TDP-35-positive SGs and facilitating the formation of TDP-43/TDP-35-positive aggresomes.
