Aberrant Glycosylation of IgG in Children With Active Lupus Nephritis Alters Podocyte Metabolism and Causes Podocyte Injury
29 Apr 2025
Abstract excerpt
OBJECTIVE: Podocytes are integral to the maintenance of the glomerular filtration barrier. Their injury results in proteinuria and disease progression in lupus nephritis (LN). Aberrant IgG glycosylation drives podocyte injury in LN and leads to cytoskeletal rearrangement, motility changes, and decreased nephrin production. Based on these findings, we hypothesized that IgG glycosylation patterns differentiate...
