Abstract

Collapsing glomerulopathy (CG) is an aggressive variant of focal and segmental glomerulosclerosis. Understanding the diverse mechanisms that can drive CG promises to uncover new therapeutic strategies. In this issue, Duret etal. identify WIP1 phosphatase as a therapeutic target for CG. Using genetic ablation and pharmacologic inhibition, they show that blockade of WIP1 activity is protective in 2 different mouse models of CG. This study highlights the complex interplay of glomerular signaling pathways in CG and offers hope for targeted therapies.
