Proteomic analysis reveals a protective role of specific macrophage subsets in liver repair

Project description:Macrophages are a heterogeneous population of immune cells that play central roles in a broad range of biological processes, including the resolution of inflammation. Although diverse macrophage subpopulations have been identified, the characterization and functional specialization of certain macrophage subsets in inflamed tissues remain unclear. Here we uncovered a key role of specific macrophage subsets in tissue repair using proteomics, bioinformatics and functional analyses. We isolated two hepatic monocyte-derived macrophage subpopulations: Ly6ChiCX3CR1lo macrophages and Ly6CloCX3CR1hi macrophages during distinct phases of acute liver injury and employed label-free proteomics approach to profile the proteome of these cells. We found that the wound healing- and endocytosis-related proteins were specifically enriched in Ly6CloCX3CR1hi macrophages. Intriguingly, 12/15-lipoxygenase (Alox15), the most strongly up-regulated protein in Ly6CloCX3CR1hi macrophages, was identified as a specific marker for these macrophages. In co-culture systems, Ly6CloCX3CR1hi macrophages specifically induced hepatocyte proliferation. Furthermore, selective depletion of this population in CD11b-diphtheria toxin receptor mice significantly delayed liver repair. Overall, our studies shed light on the functional specialization of distinct macrophage subsets in the resolution of inflammation.

Interleukin-16-knock-out bone-marrow derived macrophages response to Escherichia coli lipopolysaccharide (LPS)

Project description:We have employed whole genome microarray expression profiling to identify differently expressed genes following stimulation of interleukin-16-knock-out bone-marrow derived macrophages with Escherichia coli lipopolysaccharide (LPS). Macrophages were stimulated with LPS (100 ng/ml) for 6 hours and a signature was identified that distinguished between infected and control samples. Expression of several genes from this signature was quantified in the same RNA samples by real-time PCR, confirming the predicted macrophage response pattern. Gene expression in macrophages was measured at 6 hours after stimulation Three independent experiments were performed.

Transcription profiling of mouse Pac1+/+ versus Pac1-/- TG-macrophages treated with LPS - 6h

Project description:LPS-stimulated macrophages from Pac1+/+ and Pac1-/- mice were compared to assess gene expression changes in the absence of PAC-1 (also known as Dual specificity phosphatase 2). Experiment Overall Design: Age matched Pac1+/+ and Pac1-/- littermates were used to obtain equal numbers of thiolycollate-elicited macrophages. Pure populations of macrophages were stimulated with 100 ng/ml of LPS for 6 hours. 6 hours was chosen to assess mainly inflammatory gene expression.

Effect of Notch Signaling Inhibitor on Gene Expression in Lipopolysaccharide-stimulated Macrophages in the Presence of Immune Complex

Project description:Lipopolysaccharide (LPS)/immunue complex (IC) stimulated macrophages produce cytokine profiles that differe from LPS-stimulated inflammatory macropahges. Notch signaling is activated in LPS/IC-stimulated macrophages and inhibition of Notch signaling reduced IL-10 production. This study investigated the effect of gamma-secretase inhibitor (GSI) that suppresses Notch signaling pathway, on gene expression profiles in macrophages activated by LPS/IC.

Transcriptional and Functional Diversity of Macrophage Repolarization: Implications in Chronic Inflammation and Cystic Fibrosis

Project description:Macrophage plasticity allows cells to adopt different phenotypes, a property with potentially important implications in chronic pulmonary disorders such as cystic fibrosis (CF). We examined the transcriptional and functional significance of macrophage repolarization from an “M1” (LPS-stimulated) towards an “M2” phenotype using 5 stimuli. We found that macrophages exhibit highly diverse responses to distinct M2-polarizing stimuli. Specifically, we observed that IL-10 abrogated LPS-tolerance allowing for rapid restoration of LPS responsiveness. In contrast, IL-4 enhanced LPS-tolerance, dampening pro-inflammatory responses after repeat LPS challenge. We found enrichment of phagocytosis-associated pathways in macrophages stimulated with IL-10, leading them to display the greatest efferocytosis ability. Finally, we observed that CF macrophages had intact reparative responses, suggesting that macrophage contributions to CF lung disease are shaped by their environmental milieu and are modifiable. These findings highlight the diversity of macrophage activation states, attribute functional consequences to these stimuli, and provide a unique resource of human macrophage repolarization markers.
