STAT3 and systemic lupus erythematosus: Recently, Hedrich and colleagues demonstrated that the recruitment of Stat3 and Stat5 to the promoter and to the fourth intron of the IL10 gene in T cells varies following stimulation with different cytokines and that the imbalance between pStat3 and pStat5 in T cells from systemic lupus erythematosus (SLE) patients contributes to an increased IL‐10 expression 21.
