Abstract:
IgA nephropathy (IgAN) is currently the most common primary glomerulonephritis worldwide, with 20%-40% of patients progressing to end-stage renal disease within 20 years of diagnosis. At present, the pathogenesis of IgAN is not clear, and clinical treatment is mainly to control the progression, without specific treatment plan. A series of studies on galactose-deficient IgA1 (Gd-IgA1) suggest that the pathogenesis of IgAN involves multiple links. This review summarizes the research progress on the pathogenesis of IgAN, covering the structure characteristics of IgA1, Gd-IgA1 antibodies and Gd-IgA1 immune complexes in IgAN patients, the deposition of Gd-IgA1 immune complexes in the kidneys, kidney damage following the deposition of Gd-IgA1 immune complexes, the role of complement in IgAN, the genomics of IgAN, and mucosal immunity in IgAN, providing clues and insights for further research and clinical treatment.
