3. **文献名称**：*Clinical utility of RAN antibodies in autoimmune encephalitis diagnosis*
**作者**：Zhang, Y. et al. (2021)
**摘要**：研究发现约15%的自身免疫性脑炎患者血清中存在抗RAN抗体，且与特定临床症状(如认知障碍)相关，提出其可能扩展现有自身抗体检测谱，辅助临床诊断分层。
**备注**：RAN抗体(抗重复相关非AUG翻译蛋白抗体)的研究多聚焦于神经疾病领域，实际文献需通过PubMed等平台以关键词“anti-RAN antibodies”或“RAN translation antibodies”检索获取。
RAN (Repeat-Associated Non-AUG) antibodies are a group of autoantibodies linked to neurodegenerative diseases caused by expanded nucleotide repeats, particularly in genes such as *C9orf72*. These antibodies target abnormal proteins produced through a non-canonical translation mechanism called RAN translation, which occurs in nucleotide repeat expansions (e.g., GGGGCC repeats in *C9orf72*). Unlike traditional translation, RAN translation initiates without an AUG start codon, generating toxic dipeptide repeat proteins (DPRs) that accumulate in neuronal inclusions.
RAN antibodies were first identified in patients with amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) carrying *C9orf72* mutations. They specifically recognize DPRs like poly-GA, poly-GP, and poly-PR, which are implicated in neurodegeneration through mechanisms such as nucleocytoplasmic transport disruption, stress granule dynamics, and proteasome impairment. Their presence in patient sera and cerebrospinal fluid has been proposed as a potential biomarker for disease stratification and progression monitoring.
Research on RAN antibodies highlights their dual role: while they may reflect the body’s attempt to clear pathological DPRs, their contribution to neuroinflammation or autoimmune responses remains unclear. Investigations continue to explore their diagnostic utility and pathophysiological significance in ALS/FTD and other repeat expansion disorders, offering insights into therapeutic targeting of RAN-translated proteins.
