Project description:The anti-tumor activity of macrophages is mediated in part via phagocytosis and controlled by a balance between the recognition of live cells by activating receptors and inhibitory receptors. The latter protects host tissues during infection but allows tumoral cells to escape phagocytosis and promotes metastasis. We investigated the mechanisms that control anti-metastatic activity of macrophages and found that the transcriptional repressor and Kupffer cells (KC)-specifying factor ID3 is required and sufficient to orchestrate tumor cell killing by macrophages in vivo and in vitro and reduces by ~50% liver and lung colonization by metastatic-initiating cells invading from the portal vein in long-term orthotopic pancreatic cancer models. Loss-of-function and gain -of functions experiments indicate that ID3 controls expression of activating and inhibitory receptors, in particular the inhibitory receptor SIRPα, which boost their phagocytic activity against tumor cells. Mechanistically, ID3 prevents binding of ELK1 and the E-Box factor E2A to promoter/enhancer regions of the inhibitory receptor Sirpα gene, which limits expression of SIRPα at levels compatible with efficient phagocytosis of tumor cells and prevents its upregulation by inflammatory stimuli. This mechanism endows macrophages with anti-metastatic activity.

Project description:Background: Human lung adenocarcinoma (ADC), the predominant subtype of lung cancer, are at a disadvantage as the disease lacks available biomarkers and is not usually diagnosed until its later stages. We previously demonstrated that Tlr4-mutantmice were more susceptible to BHT-induced pulmonary inflammation (bronchoalveolar lavage macrophages and lymphocytes) and tumorigenesis in comparison to Tlr4-sufficient control mice. Differential transcriptional profiles were also noted in the whole lung tissue of the mice. The study objective was to elucidate the mechanisms underlying the protective effect of Tlr4 including differences in specific innate immune cell populations, their functional responses, and the influence of these cellular differences on the growth of ACD progenitor cell types. Methods: Following butylated hydroxytoluene (BHT) treatment (tumor promoter;4 weekly ip.injections), BALB (Tlr4-sufficient) and C.C3-Tlr4Lps-d/J (BALBLpsd; Tlr4 mutant) lungs were lavaged, processed for flow cytometry, and frozen for molecular analysis (ELISAs for IGF1, KC, Raybiotech Mouse Cytokine Array). BALF-derived macrophages were collected for phagocytosis and efferocytosis assays. BALF macrophage RNA was also isolated and utilized for Affymetrix gene arrays and real-time quantitative PCR. Enrichment of bronchiolar Clara cells, an ADC progenitor cell, was performed and cells enumerated. Femur bone marrow cells were differentiated into macrophages, and co-cultured with C10 cells, a type II cell line, for a wound healing assay. Results: Tlr4-deficiency resulted in significantly increased numbers of innate immune cells in whole lung tissue in response to BHT, including macrophages, PMNs, myeloid-derived suppressor cells (MDSC)s and dendritic cells (DCs), in comparison to Tlr4-sufficient mice (p<05). Macrophage functionality was also affected. BHT treated Tlr4-mutant mice demonstrated enhanced phagocytic and efferocytic abilities and wound healing in comparison to macrophages from Tlr4-sufficient and control treated mice (P<0.05). Additionally, Clara cell proliferation was significantly increased in Tlr4-mutant compared to Tlr4-sufficient mice in response to BHT. Pulmonary cytokine, chemokine and growth factor protein expression also significantly differed among the strains and within macrophages, gene expression and cell surface markers combined demonstrated a more plastic macrophage phenotype in the Tlr4-mutant mice. The transcriptome study identified immune pathways important in inflammation, such as phagosome. Conclusion: There are distinct pulmonary innate immune cell populations, with particular emphasis on macrophages, that are likely influencing the enhanced tumor promotion observed in Tlr4-mutant mice. Though not as striking, the pulmonary lymphoid populations may also be affecting the promotion environment, if only via their influence upon the innate immune cells. Future studies will investigate the origins of the macrophages and continued delineation of the lymphoid cell populations. Two strains of mice were used for these studies. The C.C3-Tlr4Lps-d/J (BALBLpsd) with a dominant negative Tlr4 on a BALB/c background and the BALB/cJ mice with a sufficient Tlr4. Total RNA was extracted from bronchoalveolar lavage fluid macrophages 3 days following a chronic BHT protocol. (oil controls vs BHT treated for both strains. BALB oil and BHT treatment n=3 mice per treatment group; BALBLpsd oil controls n=2 per treatment group; BALBLpsd BHT treated n = 3 per treatment group). Therefore a total of 13 arrays with one BHT exposure times and oil (vehicle) controls.

Project description:Tissue resident macrophages are functionally diverse cells that share an embryonic mesodermal origin. However, the mechanism(s) that control their specification remain unclear. We performed transcriptional, molecular and in situ spatio-temporal analyses of macrophage development in mice. We report that Erythro-Myeloid Progenitors generate pre-macrophages (pMacs) that simultaneously colonize the head and caudal embryo from embryonic day (E)9.5 in a chemokine-receptor dependent manner, to further differentiate into tissue F4/80+ macrophages. The core macrophage transcriptional program initiated in pMacs, is rapidly diversified in early macrophages as expression of transcriptional regulators becomes tissue-specific. For example, the preferential expression of the transcriptional regulator Id3 initiated in early fetal liver macrophages appears critical for Kupffer cell differentiation, as inactivation of Id3 causes a selective Kupffer cell deficiency that persists in adults. We propose that colonization of developing tissues by differentiating macrophages is immediately followed by their specification as they establish residence, hereby generating the macrophage diversity observed in post-natal tissues.

Project description:Foxp3+ regulatory T (TR) cells are phenotypically and functionally diverse, and broadly distributed in lymphoid and non-lymphoid tissues. However, the pathways guiding the differentiation of tissue-resident TR populations have not been well defined. By regulating E-protein function, Id3 controls the differentiation of CD8+ effector T cells and is essential for TR maintenance and function. We show that dynamic expression of Id3 helps define three distinct mouse TR populations, Id3+CD62LhiCD44lo central (c)TR, Id3+CD62LloCD44hi effector (e)TR and Id3- eTR. Adoptive transfer experiments and transcriptome analyses support a stepwise model of differentiation from Id3+ cTR to Id3+ eTR to Id3- eTR. Furthermore, Id3- eTR have high expression of functional inhibitory markers and a transcriptional signature of tissue-resident TR. Accordingly, Id3- eTR are highly enriched in non-lymphoid organs, but virtually absent from blood and lymph. Thus, we propose that tissue-resident TR develop in a multi-step process associated with Id3 downregulation.

Project description:<p>Macrophages are prominent immune cells in the tumor microenvironment that can be educated into pro-tumoral phenotype by tumor cells to favor tumor growth and metastasis. The mechanisms that mediate a mutualistic relationship between tumor cells and macrophages remain poorly characterized. Here, we have shown <em>in vitro</em> that different human and murine cancer cell lines release branched‐chain α‐ketoacids (BCKAs) into the extracellular milieu, which influence macrophage polarization in an monocarboxylate transporter 1 (MCT1)‐dependent manner. We found that α‐ketoisocaproate (KIC) and α‐keto‐β‐methylvalerate (KMV) induced a pro‐tumoral macrophage state, whereas α‐ketoisovalerate (KIV) exerted a pro‐inflammatory effect on macrophages. This process was further investigated by a combined metabolomics/proteomics platform. KMV and KIC altered macrophage tricarboxylic acid (TCA) cycle intermediates and increased polyamine metabolism. Proteomic and pathway analyses revealed that the three BCKAs, especially KMV, exhibited divergent effects on the inflammatory signal pathways, phagocytosis, apoptosis and redox balance. These findings uncover cancer‐derived BCKAs as novel determinants for macrophage polarization with potential to be selectively exploited for optimizing antitumor immune responses.</p>
