Macrophages as phagocytes and professional antigen presenting cells play critical roles in both innate and adaptive immunity. Main transcription factors acting during their differentiation and function are known, but the behavior and co-operation of these factors still remained unexplored. We introduce a new approach to map nucleosome-free regions using exclusively active enhancer and core promoter marking histone modification ChIP-seq data. We could detect approximately 56,000 potential active enhancers/promoters showing different lengths and histone modification shapes. Beside the highly enriched PU.1 and C/EBP sites, we could also detect binding sites for RUNX and AP-1, as well as for the MiT (MITF-TFE) family and MEF2 proteins. The PU.1 and C/EBP transcription factors are known for transforming cells into macrophages. The other transcription factors found in this study can play a role in macrophages as well, since it is known that the MiT family proteins are responsible for phagocytic activity and the MEF2 proteins specify monocytic differentiation over the granulocyte direction. Our results imply that this method can provide novel information about transcription factor organization at enhancers and core promoters as well as about the histone modifications surrounding regulatory regions in any immune or other cell types.
