Lara PC, Burgos J, Macias D. Low dose lung radiotherapy for COVID-19 pneumonia. The rationale for a cost-effective anti-inflammatory treatment. Clin Transl Radiat Oncol 2020; 23:27-29.

Abstract
The COVID-19 pandemia is affecting people worldwide. Most of the patients suffered of a respiratory disease that will progress to an acute respiratory distress syndrome (ARDS). SARS-CoV-2 pneumonia severely ill patients, develop a systemic inflammatory response with a Cytokine Release Syndrome (CRS), that is characterized by a sudden increase in several pro-inflammatory cytokines, mainly IL-1, IL-6 and TNF-alfa by activated macrophages (M1 phenotype). Blocking IL-6 with tocilizumab and using respirator equipment seems to be a very important issue in this (SARS-CoV-2) pneumonia, but not all patients are referred to such treatments. Low dose radiotherapy (0,5 Gy), is an evidence-based anti-inflammatory treatment, that could modify the immune landscape in the lung affected of SARS-CoV-2 pneumonia, through macrophages polarization to alternatively activated Macrophages (M2 phenotype). Radiation-induced cancer risk could be assumed due to the very low dose used, the advanced age of the patients and the life-threatening condition of SARS-Cov2 pneumonia. LDRT is a cost-effective non-toxic treatment already available in most general hospitals. This fact allows that it would be used for the large number of patients that will suffer this disease, and that would not receive specific anti-IL-6 treatments in ICUs in low and middle income countries.

Abstract
Macrophages, important cells of innate immunity, are known for their phagocytic activity, capability for antigen presentation, and flexible phenotypes. Macrophages are found in all tissues and therefore represent an attractive therapeutic target for the treatment of diseases of various etiology. Genetic programming of macrophages is an important issue of modern molecular and cellular medicine. The controllable activation of macrophages towards desirable phenotypes in vivo and in vitro will provide effective treatments for a number of inflammatory and proliferative diseases. This review is focused on the methods for specific alteration of gene expression in macrophages, including the controllable promotion of the desired M1 (pro-inflammatory) or M2 (anti-inflammatory) phenotypes in certain pathologies or model systems. Here we review the strategies of target selection, the methods of vector delivery, and the gene editing approaches used for modification of macrophages.

Abstract
A cytokine storm induced by SARS-Cov2 may produce pneumonitis which may be fatal for older patients with underlying lung disease. Hyper-elevation of Interleukin1 (IL-1), Tumor necrosis factor-1alfa (TNF-1 alfa), and Interleukin 6 (IL-6) produced by inflammatory macrophage M1 may damage the lung alveoli leading to severe pneumonitis, decreased oxygenation, and potential death despite artificial ventilation. Older patients may not be suitable candidates for pharmaceutical intervention targeting IL-1/6 blockade or artificial ventilation. Low dose total lung (LDTL) irradiation at a single dose of 50 cGy may stop this cytokine cascade, thus preventing, and/or reversing normal organs damage. This therapy has been proven in the past to be effective against pneumonitis of diverse etiology and could be used to prevent death of older infected patients. Thus, LDRT radiotherapy may be a cost-effective treatment for this frail patient population whom radiation -induced malignancy is not a concern because of their advanced age. This hypothesis should be tested in future prospective trials.

Abstract
Background Vulnerable plaques have been generally recognized to play a role in the pathogenesis of acute myocardial infarction (AMI), however, the role of circulating CX3CR1+CD163+ M2 monocytes has not been studied properly. We aim to evaluate the features of CX3CR1+CD163+ M2 monocytes and its relationship with cardiac specific markers in AMI patients. Methods The circulating M2 monocytes were identified in AMI patients (n=35) and healthy controls (HCs, n=10) by flow cytometry using two staining methods: CD68+CD163+ (cytoplasmic staining) and CX3CR1+CD163+ (surface staining). CX3CR1+ monocytes were purified by magnetic cell sorting. The expression level of peroxisome proliferator-activated receptor γ (PPARγ) and arginase-1 (Arg-1) were measured by real-time quantitative PCR and Western Blot in CX3CR1+ monocytes. Results Circulating M2 monocytes extremely expanded in AMI patients compared with HCs (P<0.01). Positive linear correlation was confirmed between CD68+CD163+ and CX3CR1+CD163+ cell populations in AMI patients (r=0.39, P=0.02). The percentage of circulating CX3CR1+CD163+ M2 monocytes positively correlated with cardiac specific markers (cTNT, CK-MB) and acute phase markers (glucose, hs-CRP) (cTNT, r=0.63, P<0.01, CK-MB, r=0.54, P<0.01, glucose, r=0.62, P<0.01, hs-CRP, r=0.58, P<0.01). CX3CR1+ monocytes in AMI patients expressed higher levels of PPARγ and Arg-1 than those in HCs (P<0.01). Conclusions Circulating M2 monocytes increased in AMI patients and positively correlated with the elevation of both cardiac specific and acute phase markers. CX3CR1+CD163+ M2 monocytes might have application value for the early diagnosis of AMI.

Abstract
From advances in the knowledge of the immune system, it is emerging that the specialized functions displayed by macrophages during the course of an immune response are supported by specific and dynamically-connected metabolic programs. The study of immunometabolism is demonstrating that metabolic adaptations play a critical role in modulating inflammation and, conversely, inflammation deeply influences the acquisition of specific metabolic settings.This strict connection has been proven to be crucial for the execution of defined immune functional programs and it is now under investigation with respect to several human disorders, such as diabetes, sepsis, cancer, and autoimmunity. The abnormal remodelling of the metabolic pathways in macrophages is now emerging as both marker of disease and potential target of therapeutic intervention. By focusing on key pathological conditions, namely obesity and diabetes, rheumatoid arthritis, atherosclerosis and cancer, we will review the metabolic targets suitable for therapeutic intervention in macrophages. In addition, we will discuss the major obstacles and challenges related to the development of therapeutic strategies for a pharmacological targeting of macrophage's metabolism.

Abstract
Inflammation is important for antimicrobial defense and for tissue repair after trauma. The inflammatory response and its resolution are both active processes that must be tightly regulated to maintain homeostasis. Excessive inflammation and nonresolving inflammation cause tissue damage and chronic disease, including autoinflammatory and cardiovascular diseases. An improved understanding of the cellular and molecular mechanisms that regulate inflammation has supported development of novel therapies for several inflammatory diseases, including rheumatoid arthritis and inflammatory bowel disease. Many of the specific anticytokine therapies carry a risk for excessive immunosuppression and serious side effects. The discovery of the inflammatory reflex and the increasingly detailed understanding of the molecular interactions between homeostatic neural reflexes and the immune system have laid the foundation for bioelectronic medicine in the field of inflammatory diseases. Neural interfaces and nerve stimulators are now being tested in human clinical trials and may, as the technology develops further, have advantages over conventional drugs in terms of better compliance, continuously adaptable control of dosing, better monitoring, and reduced risks for unwanted side effects. Here, we review the current mechanistic understanding of common autoinflammatory conditions, consider available therapies, and discuss the potential use of increasingly capable devices in the treatment of inflammatory disease.

Abstract
Mounting evidence suggests that aberrant immune responses are involved in the pathogenesis of osteoarthritis (OA). Synovial macrophages are likely involved. In this study, we sought to investigate the role of interferon regulatory factor 5 (IRF5). In vitro M1-polarized macrophages presented significantly higher IRF5 expression than M2-polarized macrophages. Interestingly, IRF5 expression was observed in macrophages from the synovial fluid of OA patients, and the level of IRF expression was positively correlated with disease severity, such that stage 4 OA synovial macrophages presented significantly higher levels of IRF5 than stage 2 and stage 3 OA synovial macrophages. Circulating monocytes from OA patients, on the other hand, expressed little IRF5. However, synovial fluid from OA patients could significantly upregulate IRF5 expression in circulating monocytes. Synovial macrophages also expressed significantly higher IL-12 than circulating monocytes, and circulating monocytes conditioned in OA synovial fluid demonstrated significantly higher IL-12 expression. Direct IRF5 transfection could increase IL-12 expression in circulating monocytes. Interestingly, IRF5-transfected monocytes promoted the expression of Th1-associated genes in naive CD4 T cells via an IL-12-dependent mechanism. Overall, our study demonstrated that IRF5 expression was associated with OA severity and could contribute to the activation of the M1-Th1 axis.

Abstract
Objectives: Macrophages are conventionally classified as pro-inflammatory (M1) and anti-inflammatory (M2) functional types. There is evidence for a predominance of macrophages with an inflammatory phenotype (M1) in the rheumatoid arthritis (RA) synovium. MicroRNAs (miRs) play a pivotal role in regulating the inflammatory response in innate immune cells and are found at dysregulated levels in RA patients. Here we explored miRs that tune the inflammatory function of M2-macrophages. Methods: Expression profiles of miR-221-3p and miR-155-5p were analyzed in clinical samples from RA, other inflammatory arthritis (OIA), osteoarthritis (OA), and healthy donors (HD) by qPCR. In vitro generated macrophages were transfected with miR-mimics and inhibitors. Transcriptome profiling through RNA-sequencing was performed on M2-macrophages overexpressing miR-221-3p mimic with or without LPS treatment. Secretion of IL-6, IL-10, IL-12, IL-8, and CXCL13 was measured in M1- and M2-macrophages upon TLR2/TLR3/TLR4-stimulation using ELISA. Inflammatory pathways including NF-κB, IRF3, MAPKs, and JAK3/STAT3 were evaluated by immunoblotting. Direct target interaction of miR-221-3p and predicted target sites in 3'UTR of JAK3 were examined by luciferase reporter gene assay. Results: miR-221-3p in synovial tissue and fluid was increased in RA vs. OA or OIA. Endogenous expression levels of miR-221-3p and miR-155-5p were higher in M1- than M2-macrophages derived from RA patients or HD. TLR4-stimulation of M1- and M2-macrophages resulted in downregulation of miR-221-3p, but upregulation of miR-155-5p. M2-macrophages transfected with miR-221-3p mimics secreted less IL-10 and CXCL13 but more IL-6 and IL-8, exhibited downregulation of JAK3 protein and decreased pSTAT3 activation. JAK3 was identified as new direct target of miR-221-3p in macrophages. Co-transfection of miR-221-3p/miR-155-5p mimics in M2-macrophages increased M1-specific IL-12 secretion. Conclusions: miR-221-3p acts as a regulator of TLR4-induced inflammatory M2-macrophage function by directly targeting JAK3. Dysregulated miR-221-3p expression, as seen in synovium of RA patients, leads to a diminished anti-inflammatory response and drives M2-macrophages to exhibit a M1-cytokine profile.

Abstract
Humulus japonicus (HJ) is a widely used herbal medicine in Asia with anti-oxidative, anti-microbial, and anti-inflammatory effects. We investigated the potential therapeutic effects of HJ in rheumatoid arthritis (RA) using a mouse model of collagen-induced arthritis (CIA) and a lipopolysaccharide-stimulated murine macrophage cell line (RAW 264.7). The CIA mice were administered 300 mg/kg HJ orally starting 3 days prior to second immunization. The clinical and histopathological findings were assessed in the paw of CIA mice. The levels of autoantibodies and inflammatory markers were determined in the plasma and cell culture supernatant, respectively. The expression at mRNA and protein levels was analyzed by reverse transcription quantitative-PCR and western blot analysis, respectively. HJ significantly decreased the gross arthritic scores and paw swelling in CIA mice. Furthermore, synovial inflammation, cartilage destruction, and bone erosion were markedly reduced by HJ. It also decreased the expression of inflammatory enzymes in both the paw of mice and RAW 264.7 cells. Moreover, the expression of genes related to all macrophages and pro-inflammatory M1 macrophage were significantly decreased, whereas the expression of anti-inflammatory M2 macrophage marker was markedly increased in the paw of HJ-treated CIA mice. In addition, HJ suppressed the levels of plasma anti-type II collagen antibody following the decreased expression of T helper type 1 (Th1) and Th2 cell-associated surface markers and cytokines in the paw. HJ also significantly inhibited the expression of IL-6 both in vitro and in vivo, followed by reduced STAT3 phosphorylation and expression in the paw of CIA mice. Finally, the expression of osteoclast-related genes was decreased in the paw of HJ-treated CIA mice. These findings suggest that HJ can play a role in suppressing the development of CIA by overall regulation of articular inflammation. This study should provide new insights into the use of HJ as a therapeutically effective natural product against RA.

The regulatory role of ProBDNF in monocyte function: Implications in Stanford type-A aortic dissection disease. FASEB J 2019; 34:2541-2553.

Abstract
Brain-derived neurotrophic factor precursor (proBDNF) has been reported to strengthen the dysfunction of monocytes/macrophages in animal studies. However, it is still unknown the roles of proBDNF in the dysfunction of monocytes in the inflammatory diseases in humans. In the present study, we showed that proBDNF and pan neurotrophic receptor p75 were significantly upregulated in monocytes from healthy donors (HD) after lipopolysaccharide treatment. Exogenous proBDNF treatment upregulated CD40 and proinflammatory cytokines expression in monocytes including interleukin (IL)-1β, IL-6, and tumor necrosis factor (TNF)-α. In Stanford type-A acute aortic dissection (AAD) patients, proBDNF was upregulated in CD14+ CD163+ CX3CR1+ M2- but not CD14+ CD68+ CCR2+ M1-like monocytes. In addition, sera from AAD patients activated gene expression of proinflammatory cytokines in cultured PBMCs from HD, which was attenuated by proBDNF monoclonal antibody (Ab-proB) treatment. These findings suggested that upregulation of proBDNF in M2-like monocytes may contribute to the proinflammatory response in the AAD.

Abstract
Macrophages play a key role in defending against foreign pathogens, healing wounds, and regulating tissue homeostasis. Driving this versatility is their phenotypic plasticity, which enables macrophages to respond to subtle cues in tightly coordinated ways. However, when this coordination is disrupted, macrophages can aid the progression of numerous diseases, including cancer, cardiovascular disease, and autoimmune disease. The central link between these disorders is aberrant macrophage polarization, which misguides their functional programs, secretory products, and regulation of the surrounding tissue microenvironment. As a result of their important and deterministic roles in both health and disease, macrophages have gained considerable attention as targets for drug delivery. Here, we discuss the role of macrophages in the initiation and progression of various inflammatory diseases, summarize the leading drugs used to regulate macrophages, and review drug delivery systems designed to target macrophages. We emphasize strategies that are approved for clinical use or are poised for clinical investigation. Finally, we provide a prospectus of the future of macrophage-targeted drug delivery systems.

Abstract
Bone physiology relies on the delicate balance between resorption and formation of its tissue. Bone resorption depends on a process called osteoclastogenesis in which bone-resorbing cells, i.e., osteoclasts, are produced by the differentiation of more undifferentiated progenitors and precursors. This process is governed by two main factors, monocyte-colony stimulating factor (M-CSF) and receptor activator of NFκB ligand (RANKL). While the former exerts a proliferating effect on progenitors/precursors, the latter triggers a differentiation effect on more mature cells of the same lineage. Bone homeostasis requires a perfect space–time coordination of the involved signals. When osteoclastogenesis is poorly balanced with the differentiation of the bone forming counterparts, i.e., osteoblasts, physiological bone remodelling can turn into a pathological state, causing the systematic disruption of bone tissue which results in osteopenia or osteolysis. Examples of these conditions are represented by osteoporosis, Paget’s disease, bone metastasis, and multiple myeloma. Therefore, drugs targeting osteoclastogenesis, such as bisphosphonates and an anti-RANKL monoclonal antibody, have been developed and are currently used in the treatment of such diseases. Despite their demonstrated therapeutic efficacy, these agents are unfortunately not devoid of side effects. In this regard, a condition called osteonecrosis of the jaw (ONJ) has been recently correlated with anti-resorptive therapy. In this review we will address the involvement of osteoclasts and osteoclast-related factors in the pathogenesis of ONJ. It is to be hoped that a better understanding of the biological mechanisms underlying bone remodelling will help in the design a medical therapeutic approach for ONJ as an alternative to surgical procedures.

Abstract
Inflammatory arthritis including rheumatoid arthritis (RA) and juvenile idiopathic arthritis (JIA) exhibit the shared feature of changes in activation and polarization of circulating monocytes and tissue macrophages. Numerous microRNAs (miRs) have been found to have key functions in regulating inflammation and macrophage polarization. Although there is increasing interest in the roles of miRs in both RA and JIA, less is known regarding how miRs relate to functional properties of immune cells, including monocytes and macrophages. Interestingly, miRs can function both to promote inflammatory phenotypes and pro-inflammatory polarization, as well as through negative-feedback loops to limit inflammation. Here, we review the functional roles of several miRs in macrophages in inflammatory arthritis, with a particular focus on vivo effects of miR alteration in experimental arthritis. We also consider how current efforts to target miRs clinically could modify functional monocyte and macrophage polarization in vivo, and serve as novel therapies for diseases such as RA and JIA.

Low-Dose Irradiation Differentially Impacts Macrophage Phenotype in Dependence of Fibroblast-Like Synoviocytes and Radiation Dose. J Immunol Res 2019; 2019:3161750.

Abstract
Rheumatoid arthritis (RA) is a multifactorial autoimmune disease whose main hallmark is inflammation and destruction of the joints. Two cell types within the synovium that play an important role in RA are fibroblast-like synoviocytes (FLS) and macrophages. The latter innate immune cells show a high plasticity in their phenotype and are central in inflammatory processes. Low-dose radiotherapy (LD-RT) with particularly a single dose of 0.5 Gy has been demonstrated to have a positive impact on pain, inflammation, and bone in inflamed joints. We now examined for the first time how LD-RT influences FLS and bone marrow-derived macrophages in co-culture systems of an experimental model of RA to reveal further mechanisms of immune modulatory effects of low and intermediate dose of ionizing radiation. For this, the bone marrow of hTNF-α tg mice was differentiated either with cytokines to obtain key macrophage phenotypes (M0, M1, and M2) or with supernatants (SN) of untreated or irradiated FLS. Flow cytometry analyses were used to analyse the impact of radiation (0.1, 0.5, 1.0, and 2.0 Gy) on the phenotype of macrophages in the presence or absence of SN of FLS. LD-RT had no impact on cytokine-mediated macrophage polarization in M0, M1, or M2 macrophages. However, SN of irradiated FLS particularly reduced CD206 expression on macrophages. Macrophage phenotype was stable when being in contact with SN of nonirradiated FLS, but significantly increased surface expression of CD206 and slightly decreased CD80 and CD86 expression were observed when macrophage themselves were irradiated with 0.5 Gy under these microenvironmental conditions, again highlighting discontinuous dose dependencies in the low and intermediate dose range. One can conclude that FLS-dependent microenvironmental conditions have a slight influence on the modulation of macrophage phenotype under radiation exposure conditions. Future studies are needed to reveal the impact of radiation exposure on the functions of treated macrophages under such microenvironmental conditions.

Abstract
Monocytes (Mo) and macrophages (Mϕ) are key components of the innate immune system and are involved in regulation of the initiation, development, and resolution of many inflammatory disorders. In addition, these cells also play important immunoregulatory and tissue-repairing roles to decrease immune reactions and promote tissue regeneration. Several lines of evidence have suggested a causal link between the presence or activation of these cells and the development of autoimmune diseases. In addition, Mo or Mϕ infiltration in diseased tissues is a hallmark of several autoimmune diseases. However, the detailed contributions of these cells, whether they actually initiate disease or perpetuate disease progression, and whether their phenotype and functional alteration are merely epiphenomena are still unclear in many autoimmune diseases. Additionally, little is known about their heterogeneous populations in different autoimmune diseases. Elucidating the relevance of Mo and Mϕ in autoimmune diseases and the associated mechanisms could lead to the identification of more effective therapeutic strategies in the future.

Abstract
Background/purpose Macrophages participate in the periapical inflammation with pro-inflammatory M1 cells and anti-inflammatory M2 cells. Gas6/Axl signal is the responsible pathway for the activation of M1 and polarization of M2. The aim of this study was to compare the number of CD16+ M1 cells, CD206+ M2 cells, and Gas6/Axl expression between apical granulomas and radicular cysts. Materials and methods Twenty-four cases of granuloma and twenty of cysts were submitted to immunohistochemistry using anti-CD16 and anti-CD206 antibodies for determining M1 and M2 macrophages and investigating the cells with positive Gas6 and Axl expression. Results There were more numerous of M1 macrophages in radicular cysts (175.9 ± 87.7) compared to apical granuloma (116.6 ± 55.8), and M2 macrophages was higher in cysts (204.0 ± 97.6) than granuloma (152.9 ± 64.6). The level of Gas6/Axl expression were similar. There was a significant different in M1 macrophage (P = 0.014) between two diagnosis. In patients with or without root resorption, the number of M1 were 194.6 ± 57.2 compared with 139.1 ± 79.6. The number of M2 were 241.7 ± 81.4 and 164.6 ± 77.1. The expression of Axl was stronger in root resorption patients (191.1 ± 43.6), but the tendency in Gas6 expression was similar. Significant differences were noted in high M2 infiltration and Axl positive lesions. Conclusion It appears that macrophages associated with significantly higher numbers in radicular cysts than apical granuloma. Meanwhile, macrophages and Axl receptor was intensively expressed in patients with root resorption, related to severe inflammation.

Abstract
Macrophages are central to the pathophysiology of rheumatoid arthritis (RA). They constitute the main source of pro-inflammatory cytokines and chemokines such as TNF and IL-1β, they activate a wide range of immune and non-immune cells, and they secrete diverse tissue degrading enzymes driving chronic pro-inflammatory, tissue destructive and pain responses in RA. However, they can also produce anti-inflammatory cytokines such as IL-10, secrete inhibitors of tissue degrading enzymes and promote immunoregulatory and protective responses, suggesting the existence of macrophages with distinct and diverse functional activities. Although the underlying basis of this phenomenon has remained obscure for years, emerging evidence has now provided insight into the mechanisms and molecular processes involved. Here, we review current knowledge on the biology of macrophages in RA, and highlight recent literature on the heterogeneity, origins and ontogeny of macrophages as part of the mononuclear phagocyte system. We also discuss their plasticity in the context of the M1/M2 paradigm, and the emerging theme of metabolic rewiring as a major mechanism for programming macrophage functions and pro-inflammatory activities. This sheds light into the many facets of macrophages in RA, their molecular regulation and their translational potential for developing novel protective and therapeutic strategies in the clinic.

Abstract
Genetic variants in C5orf30 have been associated with development of the autoimmune conditions primary biliary cirrhosis and rheumatoid arthritis. In rheumatoid arthritis, C5orf30 expression is cell-specific, with highest expression found in macrophages and synovial fibroblasts. C5orf30 is highly expressed in inflamed joints and is a negative regulator of tissue damage in a mouse model of inflammatory arthritis. Transcriptomic analysis from ultrasound-guided synovial biopsy of inflamed joints in a well characterized clinical cohort of newly diagnosed, disease-modifying antirheumatic drugs-naive rheumatoid arthritis patients was used to determine the clinical association of C5orf30 expression with disease activity. A combined molecular and computational biology approach was used to elucidate C5orf30 function in macrophages both in vitro and in vivo. Synovial expression of C5orf30 is inversely correlated with both clinical measures of rheumatoid arthritis disease activity and with synovial TNF mRNA expression. C5orf30 plays a role in regulating macrophage phenotype and is differentially turned over in inflammatory and anti-inflammatory macrophages. Inhibition of C5orf30 reduces wound healing/repair-associated functions of macrophages, reduces signaling required for resolution of inflammation, and decreases secretion of anti-inflammatory mediators. In an animal model of wound healing (zebrafish), C5orf30 inhibition increases the recruitment of macrophages to the wound site. Finally, we demonstrate that C5orf30 skews macrophage immunometabolism, demonstrating a mechanism for C5orf30-mediated immune regulation.

Abstract
The cholinergic anti-inflammatory pathway modulates cytokine release by activating alpha-7 nicotinic acetylcholine receptors (α7nAChR) in monocytes/macrophages. We aimed to determine the role of α7nAChR in lupus nephritis (LN). We enrolled 36 inactive and 35 active LN patients, 34 primary glomerulonephritis patients, and 35 healthy controls. Peripheral blood monocytes were isolated, and mRNA expression of α7nAChR, interleukin (IL)-1β, IL-6, IL-10, and tumor necrosis factor-alpha (TNF-α) in monocytes was measured. α7nAChR and IL-10 mRNA levels were significantly decreased, but IL-6 was increased, in LN patients compared with healthy controls or glomerulonephritis patients (all P < 0.01). Interestingly, α7nAChR mRNA levels were negatively correlated to SLEDAI (r = -0.68, P < 0.01), anti-dsDNA (r = -0.38, P < 0.05), and proteinuria (r = -0.49, P < 0.01) levels, and positively correlated to serum complement C3 levels (r = 0.38, P < 0.05) in patients with active LN. Furthermore, α7nAChR mRNA levels were negatively correlated to TNF-α (r = -0.50, P < 0.01), IL-1β (r = -0.42, P < 0.05), IL-6 (r = -0.69, P < 0.01) mRNA levels, and positively correlated to IL-10 (r = 0.45, P < 0.01). TNF-α, IL-1β, and IL-6 protein levels in the supernatant of cultured monocytes from active LN patients were significantly higher, while IL-10 was lower, than that of healthy controls. PNU-282987, an α7nAChR agonist, significantly decreased TNF-α, IL-1β, and IL-6 but increased IL-10 in the monocyte culture supernatant of active LN patients, which were abolished by an α7nAChR antagonist methyllycaconitine. The effects of PNU-282987 were confirmed in lipopolysaccharides-stimulated monocytes. Taken together, these findings suggest that decrease in α7nAChR mRNA levels may play a role in LN and that activation of α7nAChR may inhibit inflammation in LN.

Alveolar bone healing in mice genetically selected in the maximum (AIRmax) or minimum (AIRmin) inflammatory reaction. Cytokine 2018; 114:47-60. [PMID: 30584949 DOI: 10.1016/j.cyto.2018.11.027] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2018] [Revised: 11/09/2018] [Accepted: 11/27/2018] [Indexed: 01/15/2023]
Abstract
The exact role of inflammatory immune response in bone healing process is still unclear, but the success of the alveolar bone healing process seems to be associated with a moderate and transitory inflammatory response, while insufficient or exacerbated responses seems to have a detrimental influence in the healing outcome. In this context, we performed a comparative analysis of mice strains genetically selected for maximum (AIRmax) or minimum (AIRmin) acute inflammatory response to address the influence of inflammation genes in alveolar bone healing outcome. Experimental groups comprised 8-week-old male or female AIRmax and AIRmin submitted to extraction of upper right incisor, and evaluated at 0, 3, 7, 14 and 21 days after upper incision extraction by micro-computed tomography (μCT), histomorphometry, birefringence, immunohistochemistry and molecular (PCRArray) analysis. Overall, the results demonstrate a similar successful bone healing outcome at the endpoint was evidenced in both AIRmin and AIRmax strains. The histormophometric analysis reveal a slight but significant decrease in blood clot and inflammatory cells density, as well a delay in the bone formation in AIRmax strain in the early times, associated with a decreased expression of BMP2, BMP4, BMP7, TGFb1, RUNX2, and ALP. The evaluation of inflammatory cells nature reveals increased GR1+ cells counts in AIRmax strain at 3d, associated with increased levels of neutrophil chemoattractants such as CXCL1 and CXCL2, and its receptor CXCR1, while F4/80+ cell prevails in AIRmin strain at 7d. Also, our results demonstrate a relative predominance of M2 macrophages in AIRmin strain, associated with an increased expression of ARG1, IL10, TGFb, while M1 macrophages prevail in AIRmax, which parallel with increased IL-1B, IL-6 and TNF expression. At late repair stage, AIRmax presents evidences of increased bone remodeling, characterized by increased density of blood vessels and osteoclasts in parallel with decreased bone matrix density, as well increased levels of MMPs, osteoclastogenic and osteocyte markers. In the view of contrasting inflammatory and healing phenotypes of AIRmin and AIRmax strains in other models, the unpredicted phenotype observed suggests the existence of specific QTLs (Quantitative trait loci) responsible for the regulation 'sterile' inflammation and bone healing events. Despite the similar endpoint healing, AIRmax strain delayed repair was associated with increased presence of neutrophils and M1 macrophages, supporting the association of M2 cells with faster bone healing. Further studies are required to clarify the elements responsible for the regulation of inflammatory events at bone healing sites, as well the determinants of bone healing outcome.

Abstract
Patients with rheumatoid arthritis (RA) and autoantibodies, such as rheumatoid factor and those against cyclic citrullinated peptides, are designated as seropositive and have a more severe disease with worse prognosis than seronegative RA patients. Understanding the factors that participate in systemic inflammation, in addition to articular commitment, would allow better treatment approaches for prevention of RA comorbidities and disease reactivation. We evaluated whether monocyte subsets and extracellular vesicles (EVs) could contribute to this phenomenon. Seropositive patients had higher levels of proinflammatory cytokines than those of seronegative patients and healthy controls (HCs); however, this systemic inflammatory profile was unrelated to disease activity. High frequencies of circulating EVs positive for IgG, IgM, CD41a, and citrulline, together with altered counts and receptor expression of intermediate monocytes, were associated with systemic inflammation in seropositive patients; these alterations were not observed in seronegative patients, which seem to be more similar to HCs. Additionally, the EVs from seropositive patients were able to activate mononuclear phagocytes in vitro, and induced proinflammatory cytokines that were comparable to the inflammatory response observed at the systemic level in seropositive RA patients; therefore, all of these factors may contribute to the greater disease severity that has been described in these patients.

Abstract
Experimental models have often been at the origin of immunological paradigms such as the M1/M2 dichotomy following macrophage polarization. However, this clear dichotomy in animal models is not as obvious in humans, and the separating line between M1-like and M2-like macrophages is rather represented by a continuum, where boundaries are still unclear. Indeed, human infectious diseases, are characterized by either a back and forth or often a mixed profile between the pro-inflammatory microenvironment (dominated by interleukin (IL)-1β, IL-6, IL-12, IL-23 and Tumor Necrosis Factor (TNF)-α cytokines) and tissue injury driven by classically activated macrophages (M1-like) and wound healing driven by alternatively activated macrophages (M2-like) in an anti-inflammatory environment (dominated by IL-10, Transforming growth factor (TGF)-β, chemokine ligand (CCL)1, CCL2, CCL17, CCL18, and CCL22). This review brews the complexity of the situation during infectious diseases by stressing on this continuum between M1-like and M2-like extremes. We first discuss the basic biology of macrophage polarization, function, and role in the inflammatory process and its resolution. Secondly, we discuss the relevance of the macrophage polarization continuum during infectious and neglected diseases, and the possibility to interfere with such activation states as a promising therapeutic strategy in the treatment of such diseases.

Abstract
Rheumatoid arthritis (RA) is a chronic systemic autoimmune disease that primarily affects the lining of the synovial joints and is associated with progressive disability, premature death, and socioeconomic burdens. A better understanding of how the pathological mechanisms drive the deterioration of RA progress in individuals is urgently required in order to develop therapies that will effectively treat patients at each stage of the disease progress. Here we dissect the etiology and pathology at specific stages: (i) triggering, (ii) maturation, (iii) targeting, and (iv) fulminant stage, concomitant with hyperplastic synovium, cartilage damage, bone erosion, and systemic consequences. Modern pharmacologic therapies (including conventional, biological, and novel potential small molecule disease-modifying anti-rheumatic drugs) remain the mainstay of RA treatment and there has been significant progress toward achieving disease remission without joint deformity. Despite this, a significant proportion of RA patients do not effectively respond to the current therapies and thus new drugs are urgently required. This review discusses recent advances of our understanding of RA pathogenesis, disease modifying drugs, and provides perspectives on next generation therapeutics for RA. The preclinical stages of rheumatoid arthritis (RA) represent a golden window for the development of therapies which could someday prevent the onset of clinical disease. The autoimmune processes underpinning RA usually begin many years before symptoms such as joint pain and stiffness emerge. Recent studies have identified some of the key cellular players driving these processes and begun to unpick how genetic and environmental risk factors combine to trigger them; they also suggest the existence of several distinct subtypes of RA, which require further exploration. Jiake Xu at the University of Western Australia in Perth and colleagues review current treatment strategies for RA and how such insights could ultimately lead to the earlier diagnosis of RA - as well as providing new opportunities for drug treatment and prevention through behavioral changes in high-risk individuals.
