When we analyzed for the status of p-STAT3 and p-STAT4 in SLE CD8+ T cells, we observed that p-STAT3 did not show any changes with menadione or NAC treatment and that only p-STAT4 decreased with NAC treatment and is also in line with our previous observation, as p-STAT4 can modulate IFN-γ expression [54]. This evidence concerns the gene STAT3 and systemic lupus erythematosus.
