O6-Methylguanine DNA Methyltransferase Regulates Beta-glucan Trained Immunity of Macrophages

Project description:Trained immunity is the heightened state of innate immune memory that enhances immune response resulting in nonspecific protection. Epigenetic changes and metabolic reprogramming are critical steps that regulate trained immunity. In this study, we reported the involvement of O6-methylguanine DNA methyltransferase (MGMT), a DNA repair enzyme of lesion induced by alkylating agents, in regulation the trained immunity induced by β-glucan (BG). Pharmacological inhibition or silencing of MGMT expression altered LPS stimulated pro-inflammatory cytokine productions in BG-trained bone marrow derived macrophages (BMMs). Targeted deletion of Mgmt in BMMs resulted in reduction of the trained responses both in vitro and in vivo models. The transcriptomic analysis revealed that the dampening trained immunity in MGMT KO BMMs is partially mediated by ATM/FXR/AMPK axis affecting the MAPK/mTOR/HIF1α pathways and the reduction in glycolysis function. Taken together, a failure to resolve a DNA damage may have consequences for innate immune memory.

The effect of beta-glucan - induced trained immunity on the transcriptomic profile of bone marrow granulocyte-macrophage progenitors (GMP)

Project description:Induction of trained immunity by beta-glucan affects myeloid cells and their bone marrow progenitors. In particular, broad alterations in the transcriptome of trained myeloid cells have been demonstrated. In this study, we performed RNA sequencing in GMP from beta-glucan treated mice, as compared to control-treated mice, in order to investigate the impact of trained immunity on the transcriptomic profile of GMP.

The effect of beta-glucan - induced trained immunity on the epigenetic profile of bone marrow granulocyte-macrophage progenitors (GMP) and neutrophils

Project description:Induction of trained immunity by beta-glucan affects myeloid cells and their bone marrow progenitors. In particular, broad epigenetic alterations in trained myeloid cells have been demonstrated. In this study, we performed single cell ATAC sequencing in GMP and neutrophils from beta-glucan treated mice, as compared to control-treated mice, in order to investigate the impact of trained immunity on the epigenetic profile of GMP and neutrophils.

The effect of beta-glucan - induced trained immunity on the transcriptomic profile of tumor-associated monocytes

Project description:Induction of trained immunity by beta-glucan has been shown to promote transcriptomic alterations in myeloid cells. Monocytes are involved in the immune responses against tumors. In this study, we performed RNA sequencing in tumor-infiltrated monocytes from mice in order to investigate the impact of trained immunity on the transcriptomic profile of monocytes in the tumor setting.

Single-Cell Transcriptomic Analysis Reveals Neutrophil as Orchestrator during β-Glucan-Induced Trained Immunity in a Teleost Fish

Project description:We establish a trained immunity activation model in turbot (Scophthalmus maximus) by training with β-glucan in vivo. Through single cell RNA-sequencing analysis, we annotate 16 clusters of immune cells and blood cells from head kidney and spleen, and successfully characterize that neutrophils exhibit distinguished feature of trained immunity.

The effect of beta-glucan - induced trained immunity on the transcriptomic profile of tumor-associated neutrophils (TAN)

Project description:Induction of trained immunity by beta-glucan has been shown to promote transcriptomic alterations in myeloid cells. Neutrophils are involved in the immune response against tumors and can promote or inhibit tumor growth. In this study, we performed RNA sequencing in TAN from mice in order to investigate the impact of trained immunity on the transcriptomic profile of neutrophils in the tumor setting.

The effect of beta-glucan - induced trained immunity on the transcriptomic profile of bone marrow granulocyte-macrophage progenitors (GMP) in tumor-bearing mice

Project description:Induction of trained immunity by beta-glucan has been shown to promote transcriptomic alterations in myeloid cells. Progenitors in the bone marrow are also affected by trained immunity and also regulate anti-tumor immune responses . In this study, we performed RNA sequencing in GMP from tumor-bearing mice in order to investigate the impact of trained immunity on the transcriptomic profile of myeloid progenitors in the tumor setting.

Epigenetic programming during monocyte to macrophage differentiation and trained innate immunity

Project description:Monocyte differentiation into macrophages represents one of the cornerstone processes in innate host defense. In addition, immunological imprinting of either tolerance or trained immunity after an initial infection determines the functional fate of innate immune cells and the susceptibility of the host to secondary infections. Here we comprehensively characterize the epigenetic profiles of these functional states relative to healthy adult naM-CM-/ve monocytes. Inflammatory and metabolic pathways are strongly modulated in the derived macrophages, including decreased activation of inflammasome components. The cAMP-dependent signaling pathway is remodeled and adrenergic signaling was functionally implicated in trained innate immunity induction in vivo. Interestingly, M-oM-^AM-"-Glucan trains innate immune cells through extensive remodeling of distal regulatory region-bound histone acetylation, resulting in a sizeable exclusive epigenomic signature. Accordingly, genome-wide transcription factor footprint analysis reveals a specific transcription factor repertoire at trained cell-specific enhancers when recouped with epigenetic data, forming a rich hypothesis generator to manipulate innate immunity. Monocytes were pre-incubated either with cell culture medium (RPMI), M-NM-2-glucan (5M-BM-5g/mL) or with LPS (100ng/mL), for 24 hours in a total volume of 10 mL. After a wash-out, cells were cultured in RPMI supplemented with 10% human pool serum. Monocytes were collected at different time points (0 h and 6 d after treatment) and counted before further treatment for chromatin immunoprecipitation, RNA or DNaseI treatment. Different donor Buffycoats (BC) were used as independent replicates. Replicates were generated for all the profiles including ChIPseq,RNAseq and DNaseIseq.

RNA-Seq of BMDM from aged mice and the effect of trained immunity

Project description:We generated BMDMs from aged C57BL/6J mice. BMDMs were treated with C.ablican derived β-glucan, which is known to induce trained immunity. mRNA was isolated form immune trained and control BMDMs using the Rneasy Kit from Qiagen. Library preparation and sequencing performed by Novogene. We found that trained immunity induced transcriptional changes in BMDMs from aged mice
