PubMed  Due to the limited number and inaccessibility of synovial macrophages (SM), the origin of SM has not been fully illuminated. Apart from their origin and local environment, tissue macrophages express a distinctive phenotype in response to phagocytic, immune, and microbiome‐derived stimuli, underlying a complex process of activation and deactivation. Cell-mediated immunity is correlated with an influx of macrophages capable of generating reactive oxygen intermediates.

However, mononuclear phagocytes adapt their gene enhancer landscape according to the tissue of residence independently of the precursor they originated from , an ontogeny-based nomenclature may lead to different cell types with similar functionality, or to cells of the same name with different functionality depending on the organ they reside in. Beyond the 1st line of defense, macrophages have several specific characteristics across different tissues, organs, and systems. Teti G, Biondo C, Beninati C. The phagocyte, Metchnikoff, and the foundation of immunology. In response to inflammation, immune and pathologic responses, monocytes infiltrate tissues and give rise to activated macrophages with complex phenotypes. 2013;8(6):e65070. MACROPHAGES AROUND THE BODY In addition to circulating in the blood as immune sentinels, macrophages play specialized roles in different organs around the body. In the steady state, macrophages represent a mixture of embryo- and bone marrow-derived cells, responding to high local turnover of tissue-resident macrophages [28]. Frontiers Immunol.

In general tissue macrophages act as local surveillance and response cells with a diverse array of actions … Macrophages expressing CX3CR1, a chemokine receptor which is characteristic of tissue-resident cells, are important in counteracting inflammatory responses in the gut by microbial products and cytokines such as IL-22 released by activation of specialized innate lymphoid cells (the so-called ILC2/3 lymphoid cells) [57]; the uptake of apoptotic cells also induces an anti-inflammatory phenotype through TGF beta and IL-10 production by macrophages, supplemented by cytokines produced by local fibroblasts. In the immune system of human body, macrophages are the first line of defense against exogenous impairment. 2015;212(10):1497–512. These studies revealed the close association of F4/80+ macrophages with neighbouring cells, facilitated by the exquisite plasma membrane-restricted expression of this antigen marker and its stability to fixation. 2013;35(5):541–52.

The CSF-1R+ EM progenitors arise from a Tie2+ cellular pathway that eventually gives rise to the majority of resident macrophage populations in most adult tissues [40]. From [114], ©Hume et al., 1983. In addition these stromal macrophages ingest erythroid nuclei and recycle Fe. Around the time of birth, bone marrow haemopoietic stem cells (HSC) become the source of blood monocytes, replenishing resident populations with high turnover, such as gut, and in response to increased demand. J Exp Med. Macrophages were first identified as immune cells specializing in the phagocytosis of infectious agents (1). Myeloid cells of the MPS interact with cells of the lymphoid system at many levels, recognition of non-self or modified self-antigens, initiating cellular and antibody immune responses, while executing effector functions which, if excessive or perpetuated, bring about tissue destruction. Ginhoux F, Guilliams M. Tissue-resident macrophage ontogeny and homeostasis. Tissue macrophages: heterogeneity and functions Abstract. Resting microglia are characterised by extensive membrane processes which may perform additional housekeeping functions, for example in homeostasis of neurotransmitters such as glutamate, which they metabolise actively [77]. Tissue specific differentiation provides great heterogeneity between different organs. Understanding the relative importance of ResMac vs. MoD-Mac in the pool of TAM is limited by the lack of clear markers to discriminate them both in mice and … Cell. PubMed Google Scholar. The main steps in tissue-resident macrophage ontogeny, as well as the origin of specific macrophage subsets in brain, heart, and aorta, are highlighted below the schematic. For example,althoughgeneticfate-mappingstudieshaveconfirmed that the majority of macrophages in the adult heart are derived from yolk sac and fetal progenitors, CCR2+ monocyte-derived cells are the dominant macrophages driving the early inflamma- Macrophages, circulating in the blood or concatenated into different organs and tissues constitute the first barrier against any disease.

Cold Spring Harb Symp Quant Biol. Nat Immunol. Consistent with their common sinusoidal location, these major clearance functions of Kupffer cells are shared with hepatic sinusoidal endothelial cells, which are F4/80 negative, perhaps reflecting a common anatomic developmental origin. They recycle iron [46] and catabolise haem [47], an inducer of Spi-C, a transcription factor found also in other macrophages implicated in erythrocyte turnover. Medullary macrophages express F4/80 and CD68, strongly enhanced by phagocytosis of apoptotic lymphocytes. PubMed  Google Scholar. During allergic asthma, IL-4 and IL-13 production by antigen-activated Th2 lymphocytes induces M2 activated macrophages; these contribute to the further influx of monocytes by release of selected chemokines, generate arachidonate metabolites which promote bronchospasm by airway smooth muscle, goblet cell secretion and fibrosis [19, 67]. 2012;336(6077):86–90. https://doi.org/10.1186/s12915-017-0392-4, DOI: https://doi.org/10.1186/s12915-017-0392-4. 2016;4(6):MCHD-0048-2016.

In a recent study, Ensan and colleagues have shown that arterial macrophages in mice derive from both CX3CR1+ precursors in the embryonic yolk sac and from bone marrow-derived monocytes after birth [104]. Origin, development, and homeostasis of tissue-resident macrophages. 2014;5:9. These studies clearly indicate that CD169 + macrophages in different organs, and under different pathological conditions, require distinct transcription factors and local environmental signals for their development and maintenance. Macrophages are prominent in the ovary during the oestrus cycle, especially in phagocytic clearance of dying cells in the corpus luteum, and in the testis, where non-macrophage Sertoli cells remove aberrant sperm. Morris L, Graham CF, Gordon S. Macrophages in haemopoietic and other tissues of the developing mouse detected by the monoclonal antibody F4/80. Following injury and a range of neurodegenerative diseases, a subset (A1) of neurotoxic reactive astrocytes is induced by activated microglia through secretion of IL-1alpha, TNF and C1q, a component of the classic complement cascade; A1 astrocytes lose their neuronal survival, outgrowth, synaptogenesis and phagocytic activity and induce the death of neurons and oligodendrocytes [78]. 2016;44(3):439–49. Kitamura T, Qian BZ, Pollard JW. Monocytes and macrophages express a wide range of surface, vacuolar and cytosolic molecules for recognition and uptake of host-derived and foreign particles by phagocytosis, and for clearance of soluble molecules by endocytosis [25]. Bruttger and colleagues have shown that after ablation, microglial repopulation is driven by local self-renewing progenitors in response to IL-1R signalling [73]. These cells together as a group are known as the mononuclear phagocyte system and were previously known as the reticuloendothelial system. Libby and colleagues have emphasised the inflammatory network that links the brain, autonomic nervous system, bone marrow and spleen with atherosclerotic plaque and infarction [106]. Martelli D, McKinley MJ, McAllen RM. The cartoon depicts important steps in the development of monocytes and tissue-resident macrophages. Nat Rev Immunol. (2016) propose that this diversity develops "at home"-within those organs-after the recruitment of a common precursor that had not made prior commitments to diversity. Haldar M, Kohyama M, So AY, Kc W, Wu X, Briseno CG, Satpathy AT, Kretzer NM, Arase H, Rajasekaran NS, et al. Embryonic and adult-derived resident cardiac macrophages are maintained through distinct mechanisms at steady state and during inflammation. See Gordon et al. In the adult steady state and after sepsis, arterial macrophages are maintained by local proliferation rather than monocyte recruitment. Monocytes (+/-) replenish F4/80+ tissue-resident macrophages, for example in gut, liver, skin and brain, and contribute to formation of F4/80-negative osteoclasts. J Exp Med. Google Scholar. Even without activation, resident macrophages can be isolated from certain organs/tissues like; Peritoneal cavity and Spleen. Macrophages Promote Different Aspects of Metastasis. Targeted gene deletion demonstrates that the cell adhesion molecule ICAM-4 is critical for erythroblastic island formation. Microbiol Spectrum. In line with this, our in vitro data also revealed that tissue-resident macrophages isolated from spleen could upregulate tight junction-associated proteins, and in vivo depletion of tissue-resident macrophages augmented LPS-induced vascular leakage in different organs (i.e., lung, heart) of mice .

Monocytes and macrophages express F4/80 antigen after differentiation and proliferation of F4/80 negative precursors in the embryo (not shown) and bone marrow. The transcriptional regulator network of human inflammatory macrophages is defined by open chromatin. Organised macrophage-rich structures known as granulomas, for example, are formed in response to foreign bodies and chronic infections such as tuberculosis. Macrophages in different regions of the mouse spleen and lymph node perform distinct functions in immunity and haemopoietic cell turnover. Macrophage ablation induced AV block. Tissue macrophages constitute a distributed mononuclear phagocyte cellular system (MPS), contributing to the body’s responses to physiologic changes and to infectious challenge; thus, the MPS is comparable to the nervous and endocrine systems, in that it is adaptable, regulated and able to perform trophic [1] as well as defence functions, locally and systemically. Endocrine organs contain hormonal ligands for CD206; thyroglobulin naturally contains terminal residues for uptake and processing by its mannose recognition domains, whereas leutropin bears a sulphated ligand for the N-terminal cysteine-rich domain, which mediates clearance from the circulation by the liver [100].
