Histone deacetylase inhibitors suppress immature dendritic cell's migration by regulating CC chemokine receptor 1 expression.


PMID 28341057

Abstract

The modulation of immature dendritic cells (iDCs), which involves processes such as phagocytosis, migration, and maturation, is considered a beneficial research theme. Once activated by an antigen, iDCs turn to mature DCs (mDCs) and migrate towards secondary lymphoid organs, and initiate the progress of cellular immunity. Histone deacetylase inhibitors (HDACis) are also thought to be a major modulator of cellular immunity. Herein, we demonstrate that HDACis (trichostatin-A (TSA), sodium butylate (SB), scriptaid (ST)) play a central regulatory role in the migratory activity of iDCs. In our results, TSA, SB and ST showed the potent inhibitory effect on the migration of iDCs stimulated by MIP-1α. The inhibitory activities of HDACis were found to be caused by reduction of CCR1 expression on the cell surface, and by the inhibition of phosphorylation of p38 mitogen-activated protein kinase (MAPK), extracellular signal-regulated kinases 1 and 2 (ERK 1/2), and c-Jun N-terminal kinase (JNK).
