This study demonstrates the pivotal role of the local PPAR-gamma agonist system in maintaining podocyte quiescence and orchestrating the global glomerular tolerance to a severe immune-complex-mediated disease. PPAR-gamma agonist was found to be a downstream effector of the NRF2 pathway, unveiling the critical protective role of both NRF2 activity and PPAR-gamma. We also provide proof of principle that delayed PPAR-gamma agonism could display therapeutic action on glomerular function and structure in a severe model of Rapidly Progressive GlomeruloNephritis.
