Excessive apoptotic cell death and defective efferocytosis drive loss of tolerance and autoimmunity; however, a direct role for macrophage-specific defects in autoimmunity is underexplored. Here, the authors identify macrophage WDFY3 as a negative regulator of autoimmunity by enhancing efferocytosis and reducing MHC-II-mediated antigen presentation, T cell activation, and cytokine dysregulation.
