Histone Deacetylase 3 is an Epigenomic Brake in Macrophage Alternative Activation (microarray)

Project description:Macrophages, a key cellular component of inflammation, become functionally polarized in a signal- and context-specific manner. Th2 cytokines such as IL-4 polarize macrophages to a state of alternative activation that limits inflammation and promotes wound healing. Alternative activation is mediated by a transcriptional program that is influenced by epigenomic modifications including histone acetylation. To determine if Histone Deacetylase 3 (HDAC3) has a role in macrophage polarization including alternative activation, we have performed global gene expression analysis in macrophages with and without HDAC3 and with or without IL-4 exposure. From this data, we conclude that macrophages lacking histone deacetylase 3 (HDAC3) display a polarization phenotype similar to IL-4 induced alternative activation and furthermore are hyper-responsive to IL-4 stimulation. Mouse bone marrow derived macrophages were obtained from both control and HDAC3 KO animals and treated with vehicle control (BSA) or IL-4 for 24 hours. RNA was isolated and subjected to analysis using an Agilent Whole Genome Microarray Kit.

Expression data from macrophage maturation and polarization c-Myc in alternative macrophage activation experiments

Project description:In response to microenvironmental signals macrophages undergo different activation, indicated as classic/M1 and alternative/M2 polarization. C-Myc transcription factor could be an essential player in M2 polarization. Functional relevance of c-Myc in M2 macrophage biology is investigated by evaluating the effect of 100-58F4, on the transcriptional profile induced on human macrophages by IL-4. Human monocytes were obtained from normal donor buffy coats by two-step gradient centrifugation using Ficoll (Biochrom) and Percoll (Amersham). Non-adherent cells were discarded, and the purified monocytes were incubated for 7 days in RPMI 1640 (Biochom) supplemented with 10% FCS (HyClone) and 100 ng/mL M-CSF to obtain resting macrophages. Macrophage polarization was obtained by removing the culture medium and culturing cells in RPMI 1640 supplemented with 10% FCS and 100 ng/mL LPS plus 20 ng/mL IFN-gamma (M1 polarization) or 20 ng/mL IL-4 (M2 polarization) for 24 h. When needed, chemical inhibitors were added with IL-4.

Emodin inhibits macrophage alernative activation [Control-IL4-Emodin]

Project description:In order to fully characterize emodin's effects on macrophage alternative activation, peritoneal macrophages were stimulated with IL4 with or without emodin and gene expression was analyzed using a whole genome microarray. Emodin significantly attenuated the IL4 induced changes in a large percentage of genes (60%) through inhibiting multiple signaling pathways. RT-qPCR was used to confirm the results in several genes associated with M2 macrophage activation including: Arg1, Chi3l3, and CD206. Three-condition, one-color experiment: Vehicle control, IL4 or IL4-Emodin treated periferal WBC PMN samples: 4 biological replicates each.

Cholesterol homeostatic regulator SREBP2 promotes macrophage alternative activation and allergic airway inflammation

Project description:Metabolic reprogramming is well-appreciated to be able to control macrophage activation. However, it remains unknown whether the SREBPs-lipogenesis pathway is involved in macrophage alternative (or M2) activation. Here, we showed that IL4-induced M2 activation was coupled with increased SREBP2 maturation and activated cholesterol biosynthetic pathway, while the SREBP1-fatty acid biosynthesis pathway remained unaffected after IL4 stimulation. Genetic or pharmacologic blockade of SREBP2 maturation significantly inhibited IL4-induced M2 activation independent of cholesterol. Instead, cholesterol inhibited M2 activation most likely through its feedback regulation of SREBP2 maturation. Mechanically, the upregulation of SREBP2 maturation was dependent on the activation of upstream MTOR, and mature SREBP2 increased the expression of KAZALD1 and subsequently activated the IGF1 signaling to promote IL4-induced M2 activation. Consistently, myeloid-specific Scap deficiency markedly decreased the number of M2 macrophages in the lung and attenuated the HDM-induced allergic airway inflammation. Taken together, these findings highlight a critical role for cholesterol homeostatic regulator SREBP2 in M2 activation, which advances our understanding of the regulation of immunometabolism for M2 activation and points to new opportunities for therapeutic control of M2 activation and allergic airway inflammation.
