The renal lymphatic system is critical for maintaining kidney homeostasis and regulating the immune response inside the kidney. In various kidney pathological situations, the renal lymphatic network experiences lymphangiogenesis, which is defined as the creation of new lymphatic vessels. Kidney lymphangiogenesis controls immunological response inside the kidney by controlling lymphatic flow, immune cell trafficking, and immune cell regulation. Ongoing study reveals lymphangiogenesis's different architecture and functions in numerous tissues and organs. New research suggests that lymphangiogenesis in kidney disorders may regulate the renal immune response in various ways. The flexibility of lymphatic endothelial cells (LECs) improves the kidney's immunological regulatory function of lymphangiogenesis. Furthermore, current research has shown disparate findings regarding its impact on distinct renal diseases, resulting in contradictory outcomes even within the same kidney condition. The fundamental causes of the various effects of lymphangiogenesis on renal disorders remain unknown. In this thorough review, we explore the dual impacts of renal lymphangiogenesis on several kidney pathologies, with a particular emphasis on existing empirical data and new developments in understanding its immunological regulatory function in kidney disease. An improved understanding of the immunological regulatory function of lymphangiogenesis in kidney diseases might help design novel medicines targeting lymphatics to treat kidney pathologies.
肾脏的淋巴系统对于维持肾脏内环境稳定和调节肾脏内的免疫反应至关重要。在各种肾脏病理情况下,肾脏的淋巴网络经历淋巴管生成,即新淋巴管的生成。肾脏淋巴管生成通过控制淋巴液流动、免疫细胞迁移和免疫细胞调节来控制肾脏内的免疫反应。正在进行的研究揭示了淋巴管生成在许多组织和器官中的不同结构和功能。新的研究表明,肾脏疾病中的淋巴管生成可能通过多种方式调节肾脏的免疫反应。淋巴管内皮细胞(LEC)的灵活性增强了肾脏淋巴管生成的免疫调节功能。此外,目前的研究表明,其对不同肾脏疾病的影响存在差异,即使在同一肾脏疾病中也会产生相互矛盾的结果。淋巴管生成对肾脏疾病的各种影响的根本原因尚不清楚。在这篇全面的综述中,我们探讨了肾脏淋巴管生成对几种肾脏疾病的双重影响,特别强调了现有关于其在肾脏疾病中免疫调节功能的经验数据和新进展。更好地了解淋巴管生成在肾脏疾病中的免疫调节功能可能有助于设计针对淋巴管的新型药物来治疗肾脏疾病。
