In situ conversion of defective Treg into SuperTreg cells to treat advanced IPEX-like disorders in mice

Abstract

Mutations that affect Treg cell function can cause lethal autoimmunity, but whether correcting these mutations can reverse established disease is unclear. Here, the authors correct Treg cell-specific Brg1 mutation in a minor fraction of Treg cells, which supercharges these cells to rescue mice from otherwise fatal IPEX-like autoimmunity.
