Epigenetic factors that regulate TADC activity. Epigenetic enzymes that foster DC-activation include MLL complex (HMT); KDM6B and KDM4D (HDM); HDAC1 and 2 as well as TET2. Collectively these enzymes regulate the expression of genes involved in antigen presentation and stimulation of CTL-responses, such as CIITA, CD40, CD80, CD86, IL12 and IFNA/B. In contrast, enzymes such as the G9a (HMT), HDAC2, and the DNMT1, DNMT3A and DNMT3B rather inhibit DC-activity by acting on genes such as IL6, IFNA/B, CCL2, SOCS3 and IL1R. G9a, DOTL1, HDAC2 and DNMT represent potential targets to improve DC mediated anti-tumor immunity. iDC, immature dendritic cell; mDC, mature dendritic cell; HMT, histone methyltransferase; HDM, histone demethylases; HDAC, histone deacetylases.
