Type I interferon drives dysfunction of a distinct CD8+ HLA-DRB1+ T cell subset in systemic lupus erythematosus.
OBJECTIVE Systemic lupus erythematosus (SLE) is characterized by type I interferon (IFN) signaling and adaptive immune dysregulation. We previously identified hypomethylation of HLA-DRB1 and STAT1 in SLE CD8+ T cells, enabling aberrant IFN-driven HLA-DRB1 expression and expansion of a distinct CD8+ T cell subset. This...
