In this review we introduce the basic principles of epigenetic gene regulation and discuss them in the context of dendritic cell (DC) development and differentiation. Epigenetic mechanisms control the accessibility of chromatin for DNA binding proteins and thus they control gene expression. These mechanisms comprise chemical modifications of DNA and histones, chromatin remodeling and chromatin conformation. The variety of epigenetic mechanisms allow high-end fine tuning and flexibility of gene expression, a prerequisite in the process of DC lineage development.
Keywords: Chromatin accessibility; Dendritic cells; Enhancers; Epigenetic mechanisms; Gene expression regulation; Histones.
