Abstract

Introduction: Parkinson's disease (PD) is a neurodegenerative disorder caused by the misfolding of alpha-synuclein (α-synuclein) proteins. Despite treatment, misdiagnosis rates can reach up to 50% within the first five years, highlighting the need for reliable biomarkers. However, the presence and role of α-synuclein in lymphatic tissues, such as the tonsils, have not been adequately investigated. The tonsils are accessible lymphatic organs that may serve as potential sites for α-synuclein accumulation due to their rich innervation and immune activity. Therefore, this study aims to investigate and compare α-synuclein levels in the tonsillar tissues of patients with Parkinson's disease and healthy controls. By evaluating the tonsils as a potential site of α-synuclein deposition, this study aims to explore their role as a possible biomarker.

Methods: After ethical approval, participants were selected from Neurology Outpatient Clinic diagnosed with idiopathic Parkinson's per UK Parkinson's Disease Society Brain Bank Criteria. The control group comprised individuals undergoing tonsillectomy with no neurological symptoms. We collected and analyzed tonsil tissues from 15 control and 11 PD patients using ELISA to determine α-synuclein concentrations. Data were analyzed using IBM SPSS 25.0, employing Mann-Whitney U and Kolmogorov-Smirnov tests to evaluate differences in α-synuclein levels, with significance set at p<0.05.

Results: No significant age or gender differences were noted between groups. PD patients showed higher α-synuclein concentrations in tonsillar tissues compared to controls, with statistical significance.

Discussion: Our results suggest that tonsillar tissue could serve as a novel peripheral biomarker, potentially reflecting α-synuclein accumulation in PD. Future studies are needed to clarify the underlying mechanism of α-synuclein deposition in tonsils, its correlation with disease severity and progression and its potential role in monitoring treatment response.

扁桃体α -突触核蛋白积累与帕金森病的关系。
简介:帕金森病(PD)是一种由α-突触核蛋白(α-突触核蛋白)蛋白错误折叠引起的神经退行性疾病。尽管进行了治疗,但在前五年内的误诊率可高达50%,这突出了对可靠生物标志物的需求。然而,α-突触核蛋白在淋巴组织(如扁桃体)中的存在和作用尚未得到充分的研究。扁桃体是可接近的淋巴器官,由于其丰富的神经支配和免疫活性,可能成为α-突触核蛋白积累的潜在位点。因此,本研究旨在研究和比较帕金森病患者和健康对照组扁桃体组织中α-突触核蛋白的水平。通过评估扁桃体作为α-突触核蛋白沉积的潜在位点,本研究旨在探讨其作为一种可能的生物标志物的作用。方法:经伦理批准后,根据英国帕金森病协会脑库标准从神经病学门诊诊断为特发性帕金森病的参与者中选择。对照组包括接受扁桃体切除术但无神经症状的个体。我们收集了15例对照组和11例PD患者的扁桃体组织,采用ELISA法测定α-突触核蛋白浓度。采用IBM SPSS 25.0软件对数据进行分析,采用Mann-Whitney U检验和Kolmogorov-Smirnov检验评价α-synuclein水平的差异,显著性设置为:结果:组间无明显年龄、性别差异。PD患者扁桃体组织α-突触核蛋白浓度高于对照组,差异有统计学意义。讨论:我们的研究结果表明扁桃体组织可以作为一种新的外周生物标志物,潜在地反映PD中α-突触核蛋白的积累。α-突触核蛋白在扁桃体中沉积的潜在机制、与疾病严重程度和进展的相关性及其在监测治疗反应中的潜在作用有待进一步研究。
