The transcription factor EGR2 is indispensable for tissue-specific imprinting of alveolar macrophages in health and tissue repair.

Project description:Alveolar macrophages are the most abundant macrophages in the healthy lung where they play key roles in homeostasis and immune surveillance against airborne pathogens. Tissue-specific differentiation and survival of alveolar macrophages rely on niche-derived factors, such as granulocyte-macrophage colony-stimulating factor (GM-CSF) and transforming growth factor–β (TGF-β). However, the nature of the downstream molecular pathways that regulate the identity and function of alveolar macrophages and their response to injury remain poorly understood. Here, we identify that the transcription factor EGR2 is an evolutionarily conserved feature of lung alveolar macrophages and show that cell-intrinsic EGR2 is indispensable for the tissue-specific identity of alveolar macrophages. Mechanistically, we show that EGR2 is driven by TGF-β and GM-CSF in a PPAR-γ–dependent manner to control alveolar macrophage differentiation. Functionally, EGR2 was dispensable for the regulation of lipids in the airways but crucial for the effective handling of the respiratory pathogen Streptococcus pneumoniae. Last, we show that EGR2 is required for repopulation of the alveolar niche after sterile, bleomycin-induced lung injury and demonstrate that EGR2-dependent, monocyte-derived alveolar macrophages are vital for effective tissue repair after injury. Collectively, we demonstrate that EGR2 is an indispensable component of the transcriptional network controlling the identity and function of alveolar macrophages in health and disease.

ATAC-seq in wild type and EGR2 knock-out mouse alveolar macrophages

Project description:The alveolar macrophages (AMs) as a component of the innate immunity of the lung play important role in the elimination of inhaled microbes and harmful agents. The transcription factor EGR2 is a known marker transcription factor of AMs but its exact epigenetic and transcriptomic effects have not been examined. In our study, we performed ATAC-seq and RNA-seq in WT and EGR2 deficient alveolar macrophages to describe the mechanism of action and to predict potential direct target genes of EGR2. Clec7a is one of the targets of this transcription factor which is essential in the zymosan-induced inflammatory response. We further analyzed this process by applying in vivo mouse model. Our findings demonstrate that EGR2 is a key transcriptional activator, responsible for the intact protective program against different pathogens, especially fungi in AMs.

The transcription factor EGR2 is the molecular linchpin connecting STAT6 activation to the stable epigenomic program of alternative macrophage polarization

Project description:Macrophages polarize into functionally distinct subtypes while responding to microenvironmental cues. The identity of proximal transcription factors (TFs) downstream of the polarization signals are known, but their activity is typically transient, failing to explain the long-term, stable epigenomic programs developed. Here, we mapped the early and late epigenomic changes of interleukin-4 (IL-4)-induced alternative macrophage polarization. We identified the TF, Early Growth Response 2 (EGR2), bridging the early-transient and late-stable gene expression program of polarization. EGR2 is a direct target of IL-4-activated STAT6, having broad action indispensable for 77% of the induced gene signature of alternative polarization, including its autoregulation and a robust, downstream TF cascade involving PPARG. Mechanistically, EGR2 binding results in chromatin opening and the recruitment of chromatin remodelers and RNA-polymerase II. Egr2 induction is evolutionarily conserved during alternative polarization of mouse and human macrophages. In the context of tissue resident macrophages, Egr2 expression is most prominent in the lung of a variety of species. Thus, EGR2 is an example of an essential and evolutionarily conserved broad acting factor, linking transient polarization signals to stable epigenomic and transcriptional changes in macrophages.
