KMT2A and systemic lupus erythematosus: The results showed that H3K4me3 (Figure 5(a)) and MLL1 (Figure 5(b)) enrichments at the promoter in Tfh cells of the SLE group were reduced compared with those in the control group, and JMJD3 binding was positively correlated with H3K4me3 (Figure 5(c)) and MLL1 (Figure 5(d)) levels in Tfh cells from the SLE group.
