OBJECTIVE To elucidate disease-specific host protein profile in vitreous fluid of patients with intraocular inflammation due to tubercular uveitis (TBU). METHODS Vitreous samples from 13 patients with TBU (group A), 7 with non-TBU (group B) and 9 with no uveitis (group C) were analysed by shotgun proteomics using Liquid Chromatography Tandem Mass Spectrometry (LC-MS/MS). Differentially expressed proteins (DEPs) were subjected to pathway analysis using WEB-based Gene SeT Analysis Toolkit software. RESULTS Compared to control groups (B + C combined), group A (TBU) displayed 32 (11 upregulated, 21 downregulated) DEPs, which revealed an upregulation of coagulation cascades, complement and classic pathways, and downregulation of metabolism of carbohydrates, gluconeogenesis, glucose metabolism and glycolysis/gluconeogenesis pathways. When compared to group B (non-TBU) alone, TBU displayed 58 DEPs (21 upregulated, 37 downregulated), with an upregulation of apoptosis, KRAS signaling, diabetes pathways, classic pathways, and downregulation of MTORC1 signaling, glycolysis/gluconeogenesis, and glucose metabolism. CONCLUSION This differential protein profile provides novel insights into the molecular mechanisms of TBU and a baseline to explore vitreous biomarkers to differentiate TBU from non-TBU, warranting future studies to identify and validate them as a diagnostic tool in TBU. The enriched pathways generate interesting hypotheses and drive further research.

结核性葡萄膜炎患者玻璃体的蛋白质组学特征

目的 阐明结核性葡萄膜炎 (TBU) 引起的眼内炎症患者玻璃体液中的疾病特异性宿主蛋白谱。方法 使用液相色谱串联质谱 (LC-MS/MS) 通过鸟枪蛋白质组学分析来自 13 名 TBU 患者(A 组)、7 名非 TBU 患者(B 组)和 9 名无葡萄膜炎患者(C 组)的玻璃体样本。使用基于 WEB 的 Gene Set Analysis Toolkit 软件对差异表达的蛋白质 (DEP) 进行通路分析。结果 与对照组(B + C 组合)相比,A 组(TBU)显示 32 个(11 个上调,21 个下调)DEP,这表明凝血级联、补体和经典途径的上调以及碳水化合物代谢、糖异生、葡萄糖代谢和糖酵解/糖异生途径。与单独的 B 组(非 TBU)相比,TBU 表现出 58 个 DEP(21 个上调,37 个下调),细胞凋亡、KRAS 信号、糖尿病通路、经典通路的上调以及 MTORC1 信号、糖酵解/糖异生和葡萄糖代谢。结论 这种差异蛋白谱提供了对 TBU 分子机制的新见解,并为探索玻璃体生物标志物以区分 TBU 和非 TBU 提供了基线,保证未来的研究能够识别和验证它们作为 TBU 的诊断工具。丰富的途径产生了有趣的假设并推动了进一步的研究。糖酵解/糖异生和葡萄糖代谢。结论 这种差异蛋白谱提供了对 TBU 分子机制的新见解,并为探索玻璃体生物标志物以区分 TBU 和非 TBU 提供了基线,保证未来的研究能够识别和验证它们作为 TBU 的诊断工具。丰富的途径产生了有趣的假设并推动了进一步的研究。糖酵解/糖异生和葡萄糖代谢。结论 这种差异蛋白谱提供了对 TBU 分子机制的新见解,并为探索玻璃体生物标志物以区分 TBU 与非 TBU 提供了基线,保证未来的研究能够识别和验证它们作为 TBU 的诊断工具。丰富的途径产生了有趣的假设并推动了进一步的研究。
