Background: Lymphatic vessels transport lymph away from microvascular beds into the cardiovascular system. The basic function of the lymphatic system include absorption of water and macromolecules in the interstitial fluid, which plays an important role in maintaining osmotic balance of the body. Recent studies have shown that lymphangiogenesis is associated with tumor metabolism, injury repair, and chronic inflammation, and deteriorates disease progression via immune cell trafficking. Summary: Renal interstitial lymph­angiogenesis is found in patients with chronic kidney disease and a series of animal models of renal fibrosis. Lymphatic vessels transfer antigen and antigen-presenting cells from peripheral tissues to lymph nodes, which initiates adaptive immunity and in turn deteriorates renal inflammation and renal fibrosis, even in non-autoimmune renal diseases. Key Messages: This review summarizes the latest findings on how lymphatics participate in the progression of chronic kidney disease. This discussion will serve to highlight the role of adaptive immunity in non-infectious and non-autoimmune nephropathy, in order to provide new ideas and methods for prevention and treatment of kidney diseases.
