摘要

足细胞对维持肾小球滤过屏障是不可或缺的。它们的损伤导致蛋白尿和狼疮肾炎（LN）的疾病进展。异常的IgG糖基化驱动LN足细胞损伤，导致细胞骨架重排、运动性改变和肾素产生减少。基于这些发现，我们假设IgG糖基化模式区分SLE伴LN和不伴LN，并且这种异常糖基化重新编程足细胞代谢。

Aberrant glycosylation of IgG in children with active lupus nephritis alters podocyte metabolism and causes podocyte injury

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 SLE with and without LN and that this aberrant glycosylation reprograms podocyte metabolism.
