Abstract
Postmenopausal osteoporosis (PMOP) is a major public health problem worldwide, afflicting many postmenopausal women. Although many studies have focused on the biological role of individual lipids in osteoporosis, no studies have systematically elucidated the lipid profile of osteoporosis. In this study, liquid chromatography-tandem mass spectrometry (LC-MS/MS) technology based on multiple reaction monitoring (MRM) method was used to compare the levels of lipid molecules in bone marrow cells of osteoporotic mice (OVX) group and sham-operation (Sham) group. Principal component analysis (PCA) was used for multivariate statistics. Differential lipids were obtained by bar graph, heatmap and volcano map. A total of 400 lipid molecules were identified. A total of 199 lipid molecules were identified to be associated with PMOP, including 6 phospholipids and 3 sphingolipids. These differential lipid molecules provide a systematic lipid profile for osteoporosis, which helps to discover new candidate osteoporosis biomarkers, and their changes at the molecular level can be used as new targets for diagnosis or prevention.

Abstract
Osteoporosis is a common skeletal disorder characterized by an imbalance between bone resorption and formation, exhibiting a higher prevalence in women compared with men. While previous studies have primarily focused on genomics and genetics in osteoporosis susceptibility, there is a lack of systematic exploration of sex-specific differences in lipid levels in mouse bone marrow. Multiple reaction monitoring-based liquid chromatography-trandem mass spectrometry (LC-MS/MS) was used to quantify lipidomic profiles in bone marrow samples from three female mice and three male mice. The LC-MS/MS technique based on the multiple reaction monitoring method identified and quantified 184 lipids from 15 lipid classes. The contents of most lipids in the bone marrow cells of female mice were higher than those in male mice, including four polyunsaturated fatty acids, three phospholipids and four sphingolipids. Among all the lipid molecules, lactosylceramide (d18:0/16:0) showed the highest fold change in female mice, while its precursor lipid, glucosylceramide, was the most up-regulated in male mice. This study, focusing on bone marrow lipidomics, elucidates significant sexual dimorphism in lipid levels within bone marrow cells. It provides novel evidence supporting the higher prevalence of osteoporosis in women and enhances our understanding of the connection between sex-specific lipid levels and the risk of osteoporosis.

Abstract
Rheumatoid arthritis (RA) is a systemic autoimmune disease (AD) caused by the aberrant attack of the immune system on its own joint tissues. Genetic and environmental factors are the main reasons of immune system impairment and high incidence of RA. Although there are medications on the market that lessen disease activity, there is no known cure for RA, and patients are at risk in varying degrees of systemic immunosuppression. By transporting (encapsulating or surface binding) RA-related self-antigens, nucleic acids, immunomodulators, or cytokines, tolerogenic nanoparticles-also known as immunomodulatory nano-preparations-have the potential to gently regulate local immune responses and ultimately induce antigen-specific immune tolerance. We review the recent advances in immunomodulatory nano-preparations for delivering self-antigen or self-antigen plus immunomodulator, simulating apoptotic cell avatars in vivo, acting as artificial antigen-presenting cells, and based on scaffolds and gels, to provide a reference for developing new immunotherapies for RA.

Abstract
Cell death is a mystery in various forms. Whichever type of cell death, this is always accompanied by active or passive molecules release. The recent years marked the renaissance of the study of these molecules showing they can signal to and communicate with recipient cells and regulate physio- or pathological events. This review summarizes the defined forms of messages cells could spread while dying, the effects of these signals on the target tissue/cells, and how these types of communications regulate physio- or pathological processes. By doing so, this review hopes to identify major unresolved questions in the field, formulate new hypothesis worthy of further investigation, and when possible, provide references for the search of novel diagnostic/therapeutics agents.

Abstract
Mucopolysaccharidosis type II (MPS II), also known as Hunter syndrome, is a rare X-linked recessive disease caused by a deficiency of the lysosomal enzyme iduronate-2-sulfatase (IDS), which activates intracellular accumulation of nonmetabolized glycosaminoglycans such as heparan sulfate and dermatan sulfate. This accumulation causes severe damage to several tissues, principally the central nervous system. Previously, we identified 187 IDS-protein interactions in the mouse brain. To validate a subset of these interactions, we selected and cloned the coding regions of 10 candidate genes to perform a targeted yeast two-hybrid assay. The results allowed the identification of the physical interaction of IDS with LSAMP and SYT1. Although the physiological relevance of these complexes is unknown, recent advances allow us to point out that these interactions could be involved in vesicular trafficking of IDS through the interaction with SYT1, as well as to the ability to form a transcytosis module between the cellular components of the blood-brain-barrier (BBB) through its interaction with LSAMP. These results may shed light on the role of IDS on cellular homeostasis and may also contribute to the understanding of MPS II physiopathology and the development of novel therapeutic strategies to transport recombinant IDS through the brain endothelial cells toward the brain parenchyma.

Partoazar A, Goudarzi R. Phosphatidylserine liposomes containing curcumin inhibit bone loss in osteoporotic rats: A possible synergy through a common signaling pathway. J Food Biochem 2022; 46:e14120. [PMID: 35229314 DOI: 10.1111/jfbc.14120] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/01/2021] [Revised: 01/28/2022] [Accepted: 01/28/2022] [Indexed: 11/27/2022]
Abstract
The present study aimed to investigate the effect of phosphatidylserine liposomes containing curcumin (PSLs-Cur) on the development of osteoporosis induced by glucocorticoids (GCs) in the rat model. PSL-Cur, phosphatidylserine (PSL), curcumin (Cur), and alendronate (AL) drugs as a positive control were administrated orally to evaluate the beneficial effects of 3-week treatments on osteoporotic rats. The biochemical and biomechanical properties of bone parameters as well as gene expression were evaluated in treated rats. Moreover, histomorphometric examinations were performed on the bone tissues of the animals. The results revealed that PSL-Cur oral administration caused a significant improvement in serum markers, mechanical strength, and OPG gene expression rather than PSL or Cur administration in osteoporotic rats. Also, PSL-Cur significantly increased the thickness and volume of cortical and trabecular bone mass in comparison with the untreated osteoporotic group. The results of this study indicated that PSL-Cur had a more inhibitory effect on bone loss induced by GCs compared to AL standard drug. Our findings suggested that PSL-loaded Cur may be an appropriate alternative therapy for glucocorticoid-induced osteoporosis. PRACTICAL APPLICATIONS: Osteoporosis is one of the most serious metabolic chronic diseases that causes fragile bone due to decreased mineral density and microarchitectural deterioration in humans. The osteoprotective effects of curcumin and phosphatidylserine, as a food spice and supplementary diet, respectively, have been shown, previously. However, the low bioavailability of curcumin (Cur) due to its poor absorption, rapid metabolism, and fast systemic elimination, limits its benefits. This deficit can be modified with phosphatidylserine liposome (PSL) formulation that facilitates the gastrointestinal delivery of Cur. Moreover, PSL is known as an osteoprotective agent that may make synergy effect with Cur against GC-induced osteoporosis. In this study, daily oral administration of phosphatidylserine liposomes containing curcumin (PSL-Cur) for 3 weeks, considerably improved biochemical, biomechanical, and gene expression of bone parameters in the treated animals subjected to osteoporosis. PSL-Cur can significantly increase the thickness and volume of cortical and trabecular bone mass as well as the mechanical bone strength in animals. Experimental findings proposed PSL-Cur consumption as a proper and safe supplementary medication in the controlling of bone loss in patients with a high risk of osteoporosis.

Polymer nanotherapeutics to correct autoimmunity. J Control Release 2022; 343:152-174.

Abstract
The immune system maintains homeostasis and protects the body from pathogens, mutated cells, and other harmful substances. When immune homeostasis is disrupted, excessive autoimmunity will lead to diseases. To inhibit the unexpected immune responses and reduce the impact of treatment on immunoprotective functions, polymer nanotherapeutics, such as nanomedicines, nanovaccines, and nanodecoys, were developed as part of an advanced strategy for precise immunomodulation. Nanomedicines transport cytotoxic drugs to target sites to reduce the occurrence of side effects and increase the stability and bioactivity of various immunomodulating agents, especially nucleic acids and cytokines. In addition, polymer nanomaterials carrying autoantigens used as nanovaccines can induce antigen-specific immune tolerance without interfering with protective immune responses. The precise immunomodulatory function of nanovaccines has broad prospects for the treatment of immune related-diseases. Besides, nanodecoys, which are designed to protect the body from various pathogenic substances by intravenous administration, are a simple and relatively noninvasive treatment. Herein, we have discussed and predicted the application of polymer nanotherapeutics in the correction of autoimmunity, including treating autoimmune diseases, controlling hypersensitivity, and avoiding transplant rejection.

Abstract
Phosphatidylserine-containing liposomes (PSLs) can mimic the anti-inflammatory effects of apoptotic cells by binding to the phosphatidylserine receptors of macrophages. MGF-E8, a bridge molecule between phosphatidylserine and macrophages, can promote M2 polarization by activating macrophage integrin with its arginine-glycine-aspartic acid (RGD) motif. In this study, to mimic MGF-E8, PSLs presenting RGD peptide (RGD-PSLs) were prepared, and their immunomodulatory effects on macrophages and the bone tissue regeneration of rat calvarial defects were investigated. RGD peptides enhanced the phagocytosis of PSLs by macrophages, especially when the PSLs contained 3% RGD. RGD-PSLs were also more effective than PSLs for the suppression of lipopolysaccharide-induced gene expression of proinflammatory cytokines (i.e., IL-1β, IL-6, and TNF-α) as well as CD86 (M1 marker) expression. Furthermore, RGD promoted PSL-induced M2 polarization: 3%-RGD-PSLs significantly enhanced the mRNA expression of Arg-1, FIZZ1, and YM-1, as well as CD206 (M2 marker) expression. In a calvarial defect model, a significant increase in M2 with a decrease in M1 macrophages was observed with 3%-RGD-PSL treatment compared with the effects of PSLs alone. Finally, new bone formation was also accelerated by 3%-RGD-PSLs. Thus, these results suggest that the intensive immunomodulatory effect of RGD-PSLs led to the enhancement of bone tissue regeneration.

Abstract
Macrophages play a key role in inflammation, infection, cancer, and repairing damaged tissues. Thus, modulating macrophages with engineered nanomaterials is an important therapeutic strategy for healing chronic inflammatory injuries. However, designing and manufacturing therapeutic nanomaterials remains challenging. Therefore, in this study, apoptotic-cell-inspired deformable phosphatidylserine (PS)- containing nanoliposomes (D-PSLs) with a Young's modulus (E) of approximately 0.5 kPa were constructed via a facile and scalable method. Compared with similar-sized conventional PSLs with an E of approximately 80 kPa, the d-PSLs had a lower uptake efficacy, a much longer binding time to the cell surface, and induced enhanced anti-inflammatory and pro-healing effects via the synergistic effects of their mechanical stimulus and PS-receptor mediation after recognition by macrophages. In particular, chronic wound healing in diabetic rats showed that d-PSLs can efficiently promote M2-like macrophage polarization, increase the expression of the vascular endothelial marker CD31 and accelerate wound closure. Our findings suggest that soft d-PSLs represent a promising biomimetic nano-therapeutic approach for macrophage immunotherapy for chronic inflammatory injury, and that the mechanical stimulus of nanomaterials significantly affects the receptor-mediated biological responses, which will inspire the design of engineered nanomaterials for biomedical applications. STATEMENT OF SIGNIFICANCE: Macrophages play a significant role in restoring tissue homeostasis by modulating inflammation and wound healing. Specifically, an M1/M2 macrophage imbalance contributes to various inflammatory disorders. However, modulating macrophages with engineered nanomaterials remains a challenge. In this study, apoptotic-cell-inspired deformable phosphatidylserine (PS)- containing nanoliposomes (D-PSLs) were constructed to explore their interactions with macrophages, and evaluate their anti-inflammatory and pro-healing effects on chronic wounds in diabetic rats. We found that soft d-PSLs can persistently bind to macrophage membranes and enhance the anti-inflammatory and pro-healing responses of macrophages, which not only sheds new light on the design of therapeutic biomaterials based on regulating macrophages but also provide a promising biomimetic nano-therapeutic approach for chronic inflammatory injury.

Abstract
Rheumatoid arthritis (RA) is a chronic immune-mediated disease managed by conventional synthetic drugs, such as methotrexate (MTX), and targeted drugs including biological agents. Cell-based therapeutic approaches are currently developed in RA, mainly mesenchymal stroma cell-based approaches. Early-stage apoptotic cells possess direct and indirect anti-inflammatory properties. During the elimination of dying cells (a process called efferocytosis), specific mechanisms operate to control immune responses. There are compelling evidences in experimental models of arthritis indicating that apoptotic cell administration may benefit joint inflammation, and may even have therapeutic effects on arthritis. Additionally, it has been demonstrated that apoptotic cells could be administered with standard treatments of RA, such as MTX or TNF inhibitors (TNFi), given even a synergistic response with TNFi. Interestingly, apoptotic cell infusion has been successfully experienced to prevent acute graft-vs.-host disease after hematopoietic cell transplantation in patients with hematologic malignancies, with a good safety profile. In this mini-review, the apoptotic cell-based therapy development in arthritis is discussed, as well as its transfer in the short-term to an innovative treatment for patients with RA. The use of apoptotic cell-derived factors, including secretome or phosphatidylserine-containing liposomes, in RA are also discussed.

Towards the Development of Long Circulating Phosphatidylserine (PS)- and Phosphatidylglycerol (PG)-Enriched Anti-Inflammatory Liposomes: Is PEGylation Effective? Pharmaceutics 2021; 13:pharmaceutics13020282. [PMID: 33669803 PMCID: PMC7922817 DOI: 10.3390/pharmaceutics13020282] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2021] [Revised: 02/11/2021] [Accepted: 02/17/2021] [Indexed: 12/20/2022] Open
Abstract
The anionic phospholipids (PLs) phosphatidylserine (PS) and phosphatidylglycerol (PG) are endogenous phospholipids with anti-inflammatory and immunomodulatory activity. A potential clinical use requires well-defined systems and for several applications, a long circulation time is desirable. Therefore, we aimed the development of long circulating liposomes with intrinsic anti-inflammatory activity. Hence, PS- and PG-enriched liposomes were produced, whilst phosphatidylcholine (PC) liposomes served as control. Liposomes were either formulated as conventional or PEGylated formulations. They had diameters below 150 nm, narrow size distributions and composition-dependent surface charges. Pharmacokinetics were assessed non-invasively via in vivo fluorescence imaging (FI) and ex vivo in excised organs over 2 days. PC liposomes, conventionally formulated, were rapidly cleared from the circulation, while PEGylation resulted in prolongation of liposome circulation robustly distributing among most organs. In contrast, PS and PG liposomes, both as conventional or PEGylated formulations, were rapidly cleared. Non-PEGylated PS and PG liposomes did accumulate almost exclusively in the liver. In contrast, PEGylated PS and PG liposomes were observed mainly in liver and spleen. In summary, PEGylation of PS and PG liposomes was not effective to prolong the circulation time but caused a higher uptake in the spleen.

Abstract
Asthma, chronic obstructive pulmonary disease (COPD), and cystic fibrosis (CF) are major inflammatory respiratory diseases. Current mainstay therapy for asthma, and chronic obstructive pulmonary disease are corticosteroids, which have well-established side effect profiles. Phospholipids (PLs) are ubiquitous, diverse compounds with varying functions such as their structural role incell membrane, energy storage, and cell signaling.Recent advances in understanding PLs role as inflammatory mediators in the body as well as their widespread long-standing use as carrier molecules in drug delivery demonstrate the potential application of phospholipids in modulating inflammatory conditions. This review briefly explains the main mechanisms of inflammation in chronic respiratory diseases, currentanti-inflammatory treatments and areas of unmet need. The structural features, roles of endogenous and exogenous phospholipids, including their use as pharmaceutical excipients are reviewed. Current research on the immunomodulatory properties of PLs and their potentialapplication in inflammatory diseasesis the major section of this review. Considering the roles of PLs as inflammatory mediators and their safety profile established in pharmaceutical formulations, these small molecules demonstrate great potential as candidates in respiratory inflammation. Future studies need to focus on the immunomodulatory properties and the underlying mechanisms of phospholipids in respiratory inflammatory diseases.

Abstract
Introduction: Treatment of osteoporosis with the available drug formulations is still challenging due to multiple associated limitations such as chronic treatment, off-target side effects, poor bone targeting, and low bioavailability. Adopting advanced bone-targeted drug delivery strategies like liposomes is one of the safe and effective approaches for osteoporosis treatment.Areas covered: This review summarizes the applications of liposomes in gene delivery, bone regeneration, bone-targeted delivery, and as a carrier for drug encapsulation in the treatment of osteoporosis. Details of all the supportive studies are discussed here and the bone-specific roles of the strategies like new generation liposomes in osteoporosis are elaborated. The future scope of performing in-depth research on the bone-targeted liposomes is discussed.Expert opinion: Liposomes-based bone-targeted delivery of therapeutics seems to be a promising approach for the effective treatment of osteoporosis. But till date, the tremendous in vitro and in vivo research on liposomes has failed to attain significant progress in their clinical translation. From bench to bedside success of the research an interdisciplinary collaboration between the preclinical and clinical experts engaged at different stages of liposomes development is required.

Abstract
BACKGROUND Liposomes containing docosahexaenoic acid (DHA) and phosphatidylserine were claimed to inhibit osteoclast formation and bone resorption in the inflammatory status. Herein, we proposed that an apoptotic mimicry (SQ liposome) prepared from squid-skin phospholipids can explore the suppressive osteoclastogenesis. METHODS The intermolecular fatty-acid composition in the phospholipid of squid-skin extract was analyzed by GC-FID. The SQ liposome structure was characterized by size distribution and zeta potential (ζ). RAW 264.7 cell is used to study the effect of SQ liposomes on osteoclast differentiation. Secretion of prostaglandin E2 (PGE2) and transforming growth factor-β (TGF-β) from RAW 264.7 cells were assayed. Antiosteoclastogenesis effects were performed via the tartrate-resistant acid phosphatase (TRAP)-positive multinucleated cell (MNC) counting, bone resorption pit assay, and TRAP activity analysis. The specific gene expressions related to antiosteoclastogenesis were also detected. RESULTS An apoptotic mimicry through the use of a single-layer liposome (SQ liposome) with phosphatidylserine exposure contains DHA (28.7%) and eicosapentaenoic acid (EPA, 11.8%). Co-treatment with receptor activator of nuclear factor kappa B ligand (RANKL)/macrophage colony-stimulating factor induced RAW 264.7-cell differentiation into mature osteoclasts, thus enhancing PGE2 and TGF-β secretion. However, cotreatment with 1 mg/mL of SQ liposome restored (p < 0.05) the cell viabilities under the RANKL stress. Increased PGE2 levels was downregulated (p < 0.05) in cotreatments with 0.11 and 0.33 mg/mL of SQ liposome, but on the TGF-β levels were not (p > 0.05) influenced in SQ liposome cotreatments. Cotreatments with 0.33-1 mg/mL of SQ liposome suppressed (p < 0.05) the osteoclast maturation (such as decreased MNCs and bone pit formation), inhibited TRAP activities, and downregulated the osteoclastogenesis-related gene expressions. CONCLUSION In summary, current data support that a possible prevention of our prepared SQ liposomes which are rich in DHA and EPA on bone loss is through the suppression of osteoclastogenesis. Moreover, based on the results from this study an in vivo study warrants a further investigation.

Abstract
Cancer immunotherapies, particularly therapeutic vaccination, do not typically generate robust anti-tumour immune responses. Here, we show that the intratumoral burst release of the protein annexin A5 from intravenously injected hollow mesoporous nanoparticles made of diselenide-bridged organosilica generates robust anti-tumour immunity by exploiting the capacity of primary tumours to act as antigen depots. Annexin A5 blocks immunosuppressive apoptosis and promotes immunostimulatory secondary necrosis by binding to the phagocytic marker phosphatidylserine on dying tumour cells. In mice bearing large established tumours, the burst release of annexin A5 owing to diselenide-bond cleavage under the oxidizing conditions of the tumour microenvironment and the reducing intracellular conditions of tumour cells induced systemic cytotoxic T-cell responses and immunological memory associated with tumour regression and the prevention of relapse, and led to complete tumour eradication in about 50% of mice with orthotopic breast tumours. Reducing apoptosis signalling via in situ vaccination could be a versatile strategy for the generation of adaptive anti-tumour immune responses.

Abstract
Phosphatidylserine nanocochleates (Nanocochs) are novel delivery systems that may play a prominent osteoprotective role with their cargo, vitamin D3 (Vit-D3), against osteoporosis. Therefore, this study was conducted to characterize a Nanococh containing vitamin D3 (Nanococh-D3) and investigate its potential role in improving GIO in a rat model. Roll-shaped Nanococh-D3 particles were obtained in a size range of 320 nm with a sustained release performance. Oral Nanococh-D3 significantly increased the bioavailability of Vit-D3, enhanced bone mechanical strength, and improved osteogenic biomarkers including B-ALP, osteocalcin, Ca, and OPG in GIO rats. This formulation markedly suppressed gene expression of RANK and RANKL in treated rats. Histomorphometric analysis showed significant repairs in bone tissues and TRAP staining indicated a significant decrease in osteoclasts using Nanococh-D3 in osteoporotic rats. Nanococh alone similar to Nanococh-D3 acted better than AL as a standard anti-osteoporotic drug in the improvement of bone strength. In conclusion, our results established the potential role of Nanococh-D3 against osteoporosis in rats.

Abstract
Phosphatidylserine (PS) and phosphatidylglycerol (PG) are naturally occurring phospholipids (PL) with intrinsic anti-inflammatory properties. The therapeutic potential of PS and PG has not been extensively explored and the main focus had been directed towards PS- and PG-liposomes. In order to increase the formulation options, we explored whether mixed micelles (MM) could be an alternative to liposomes. Potential advantages of MM are their thermodynamic stability, small size and ease of manufacture. DOPS- and DOPG-enriched MM were obtained via a co-precipitation technique and physicochemical characterization was performed. The MM, approximately 10 nm in diameter, showed no toxicity on fibroblast cell lines in vitro and virtually no hemolytic activity. The MM suppressed the TNFα-production of mIFNγ/LPS-stimulated mouse peritoneal macrophages (MPM) in vitro similar to DOPS- and DOPG-liposomes. Therefore, DOPS- and DOPG-loaded MM are promising new options for the treatment of inflammatory diseases.

Abstract
A new group of non-ionic amphiphiles with short alkyl chains and functionalizable oxanorbornane-based head group for drug delivery application are presented. They can be prepared through a sequence that starts with cycloaddition of Boc-protected furfuryl amine with maleic anhydride and reduction of the resulting adduct with LiAlH4 to get a diol intermediate. Introduction of alkyl chains through these primary hydroxyl groups and subsequent head-group modification via cis-hydroxylation resulted in a number of new amphiphiles in good yields. They were characterized by various spectro-analytical techniques and then subjected to drug-delivery studies using ibuprofen as a model drug. Functionalization of the head group through the amine functionality was also done with an intention to improve lipid packing to get better drug-loading and release properties. Irrespective of the nature of groups attached through this amine unit, all amphiphiles with short alkyl chains were found to assemble into spherical aggregates when drop-casted from various organic solvents. The same assembly preference prevailed in their formulations containing lipid-cholesterol-drug in 1: 0.5:1 ratio as well, and these particles had diameters <300 nm. Apart from good drug-loading efficiencies, these amphiphiles exhibited controlled release properties and did not show any indication of toxicity when assayed against NIH3T3 cells. The formulation based on lipid having a phenylalanine unit on the head group (1.10c) turned out to be the best in this series which showed a loading efficiency of 57.6% with a controlled release of ~42% by end of 24 h. Because of efficient layering that is facilitated by hydrogen bonding involving well-directed hydroxyl groups on the head group, amphiphiles with alkyl chains as short as C5 are able to act as efficient drug delivery systems, which is one of the highlights of this work.

Abstract
BACKGROUND Alzheimer's disease (AD) and bone loss are clinically exacerbated. However, the mechanism of exacerbation remains understood. OBJECTIVE We tested our hypothesis that periodontitis is involved in the exacerbation, contributing to AD pathologies. METHODS The bone, memory, and inflammation in bone and brain were examined in 12-month-old mice after systemic exposure to lipopolysaccharide from Porphyromonas gingivalis (P gLPS) for 3 consecutive weeks. RESULTS Compared with control mice, bone loss in tibia (26% decrease) and memory decline (47% decrease) were induced in mice with a positive correlation after exposure to P gLPS (r = 0.7378, p = 0.0011). The IL-6 and IL-17 expression in tibia was negatively correlated with the bone volume/total tissue volume (r = -0.6619, p = 0.0052; r = -0.7129, p = 0.0019), while that in the cortex was negatively correlated with the memory test latency (r = -0.7198, p = 0.0017; p = 0.0351, r = -0.5291). Furthermore, the IL-17 expression in microglia was positively correlated with Aβ42 accumulation in neurons (r = 0.8635, p < 0.0001). In cultured MG6 microglia, the P gLPS-increased IL-6 expression was inhibited by a PI3K-specific inhibitor (68% decrease), and that of IL-17 was inhibited by IL-6 antibody (41% decrease). In cultured N2a neurons, conditioned medium from P gLPS-stimulated microglia (MCM) but not P gLPS increased the productions of AβPP, CatB, and Aβ42, which were significantly inhibited by pre-treatment with IL-17 antibody (67%, 51%, and 41% decrease). CONCLUSION These findings demonstrated that chronic systemic exposure to P gLPS simultaneously induces inflammation-dependent bone loss and AD-like pathologies by elevating IL-6 and IL-17 from middle age, suggesting that periodontal bacteria induce exacerbation of bone loss and memory decline, resulting in AD progression.

Abstract
The field of biomaterials has seen a strong rejuvenation due to the new potential to modulate immune system in our body. This special class of materials is called "immunomodulatory biomaterials". Generally, three fundamental strategies are followed in the design of immunomodulatory biomaterials: (1) immuno-inert biomaterials, (2) immuno-activating biomaterials, and (3) immuno-tolerant biomaterials. While many applications of immuno-inert biomaterials such as biocompatible medical implants have been already proposed in the past decades, the ability to engineer biological activity into synthetic materials greatly increases the number of their potential uses and improves their performance in more traditional applications. The major focus of researchers is now set on developing immuno-tolerant biomaterials for anti-inflammatory therapies. In this review, we therefore introduce recent developments of immuno-tolerant biomaterials. Especially we introduce an apoptotic cell membrane-inspired polymer and its post-inflammatory effects on immune cells in this article.

Abstract
Placement of dental implants initiates inflammatory foreign body response, in which macrophages play a central role and affect the subsequent tissue healing process such as bone formation. The purpose of this study was to fabricate phosphatidylserine (PS)-containing supported lipid bilayers (SLBs) on a titanium surface to regulate the polarization of macrophages, a critical factor that affects following tissue healing and regeneration. The fluorescent recovery after photobleaching images showed that the percentage of PS had a critical influence on the fluidity, and 20% PS had the highest fluidity. Furthermore, more expanded and elongated cells were observed in the SLB-coated groups. transforming growth factor-β1 and vascular endothelial growth factor, the key cytokine markers of M2 macrophage polarization, were increased in the SLB-coated groups, especially in the 20% PS group. Consistently, cells cultured on the SLB-coated titanium exhibited the distribution of CD206+ , which is a M2 macrophage specific maker. The results of this study demonstrated M2 polarization of macrophages on PS-SLB-coated titanium discs, which suggests the application of PS-SLB as an immune-regulating coating material to improve tissue reactions to dental implants. © 2018 Wiley Periodicals, Inc.

Abstract
Phosphatidylserine (PtdSer) is mainly derived from the bovine brain cortex or soybean lecithin. We investigated macrophage uptake behavior and the anti-inflammatory response induced by liposomes containing bovine brain- (B-PSL) or soybean-derived PtdSer (S-PSL). The size of B-PSL and S-PSL was very similar. There were no significant differences in the uptake of B-PSL and S-PSL by Raw 264.7 macrophage cells. Addition of B-PSL or S-PSL decreased the production of the inflammatory cytokines, IL-1α, IL-6 and TNF-α, in lipopolysaccharide-treated Raw 264.7 cells, but there were no differences between them. These results suggest that S-PSL may be used as an anti-inflammatory agent.

Abstract
Phosphatidylserine (PS) exposure during apoptosis leads to silent clearance of cells without adverse immune reactions to self-proteins. Given the biological functions of PS in cellular cleanup and global immunosuppression, we hypothesized that administration of PS-protein complexes would reduce immunogenicity. Here, we report that exposing Pompe disease mice to acid alpha glucosidase (rhGAA) with PS or immunosuppressant dexamethasone resulted in lower anti-rhGAA antibodies than in animals receiving rhGAA alone. However, upon rechallenge with rhGAA, only PS-rhGAA pre-exposed mice displayed a durable hyporesponsiveness even after PS administration was ceased. Thus, pre-exposure of antigens administered together with PS were not silently cleared, but the immune system acquired memory about the antigen that averted mounting of a response during rechallenge. In hemophilia A mice, PS hyporesponsiveness toward Factor VIII was reversed by administration of function-blocking antibody against the PS receptor T-cell immunoglobulin and mucin 4, implicating this receptor in PS's effect. Moreover, pre-exposure of myelin oligodendrocyte glycoprotein peptide with PS delayed the onset and reduced the severity of experimental autoimmune encephalomyelitis. These observations suggest that PS's function in apoptosis is not limited to silent antigen clearance without immune responses toward self-proteins but shows that PS reduces immune response during rechallenge to several antigens that also involves initiation of antigen tolerance.

Abstract
Bone-resorbing multinucleated osteoclasts that play a central role in the maintenance and repair of our bones are formed from bone marrow myeloid progenitor cells by a complex differentiation process that culminates in fusion of mononuclear osteoclast precursors. In this study, we uncoupled the cell fusion step from both pre-fusion stages of osteoclastogenic differentiation and the post-fusion expansion of the nascent fusion connections. We accumulated ready-to-fuse cells in the presence of the fusion inhibitor lysophosphatidylcholine and then removed the inhibitor to study synchronized cell fusion. We found that osteoclast fusion required the dendrocyte-expressed seven transmembrane protein (DC-STAMP)-dependent non-apoptotic exposure of phosphatidylserine at the surface of fusion-committed cells. Fusion also depended on extracellular annexins, phosphatidylserine-binding proteins, which, along with annexin-binding protein S100A4, regulated fusogenic activity of syncytin 1. Thus, in contrast to fusion processes mediated by a single protein, such as epithelial cell fusion in Caenorhabditis elegans, the cell fusion step in osteoclastogenesis is controlled by phosphatidylserine-regulated activity of several proteins.

Abstract
Homeostasis of intraocular pressure (IOP) is important for the maintenance of anterior eye anatomic integrity, minimizing pressure-associated damage to the optic nerve, and maintaining a pressure gradient for blood flow to the eye. IOP is regulated by equilibrium between aqueous humor (AH) production and its outflow. The ciliary body (CB) is thought to actively secrete AH. However, whether AH composition and in particular, its phospholipids are entirely due to CB secretion remains uncertain. Comparison of phospholipids released by cultured CB, phospholipids present within CB tissue, within AH, and within blood and serum are consistent with release of most phospholipids into the AH by the CB. Treatment of CB in culture with timolol, a non-specific beta-adrenergic antagonist, alters the release of phospholipids by CB into the media. However, dorzalamide, a carbonic anhydrase inhibitor that reduces production of AH, does not affect phospholipid release thereby suggesting timolol, which also decreases IOP through decreased AH outflow, affects other physiological homeostatic mechanisms regulating aqueous outflow. These outflow changes also affect the composition of secreted phospholipids. We present evidence that release of lipids by the CB has a prolonged survival effect on cultured primary TM cells and TM tissue.

Abstract
Apoptotic cell death serves important roles in homeostasis by eliminating dangerous, damaged, or unnecessary cells without causing an inflammatory response by externalizing phosphatidylserine to the outer leaflet in the phospholipid bilayer. In this study, we newly designed apoptotic cell membrane-inspired monomer and polymer which have the phosphoryl serine group as the anti-inflammatory functional moiety and demonstrate here for the first time that administration of an apoptotic cell membrane-inspired phosphorylserine polymer can protect murine macrophages (RAW 264.7) from lipopolysaccharide-induced inflammation. Interestingly, statistical copolymers with phosphorylcholine monomer that mimicked more precisely the apoptotic cell membrane result in more effective suppression of macrophage activation. This study provides new insights into the rational design of effective polymeric materials for anti-inflammatory therapies.

Abstract
Osteoporosis is a common skeletal disorder characterized by low bone mass leading to increased bone fragility and fracture susceptibility. The bone building cells, osteoblasts, are derived from mesenchymal stromal cells (MSCs); however, with increasing age osteogenic differentiation is diminished and more adipocytes are seen in the bone marrow, suggesting a shift in MSC lineage commitment. Identification of specific factors that stimulate osteoblast differentiation from human MSCs may deliver therapeutic targets to treat osteoporosis. The aim of this study was to identify novel genes involved in osteoblast differentiation of human bone marrow–derived MSCs (hMSCs). We identified the gene chloride intracellular channel protein 3 (CLIC3) to be strongly upregulated during MSC‐derived osteoblast differentiation. Lentiviral overexpression of CLIC3 in hMSCs caused a 60% increase of matrix mineralization. Conversely, knockdown of CLIC3 in hMSCs using two short‐hairpin RNAs (shRNAs) against CLIC3 resulted in a 69% to 76% reduction in CLIC3 mRNA expression, 53% to 37% less alkaline phosphatase (ALP) activity, and 78% to 88% less matrix mineralization compared to scrambled control. Next, we used an in vivo human bone formation model in which hMSCs lentivirally transduced with the CLIC3 overexpression construct were loaded onto a scaffold (hydroxyapatite‐tricalcium‐phosphate), implanted under the skin of NOD‐SCID mice, and analyzed for bone formation 8 weeks later. CLIC3 overexpression led to a 15‐fold increase in bone formation (0.33% versus 5.05% bone area relative to scaffold). Using a Clic3‐His‐tagged pull‐down assay and liquid chromatography–mass spectrometry (LS/MS)‐based proteomics analysis in lysates of osteogenically differentiated hMSCs, we showed that CLIC3 interacts with NIMA‐related kinase 9 (NEK9) and phosphatidylserine synthase 1 (PTDSS1) in vitro, and this finding was supported by immunofluorescent analysis. In addition, inhibition of NEK9 or PTDSS1 gene expression by shRNAs inhibited osteoblast differentiation and mineralization. In conclusion, we successfully identified CLIC3 to be a lineage‐specific gene regulating osteoblast differentiation and bone formation through its interaction with NEK9 and PTDSS1. © The Authors.

Abstract
OBJECTIVES Neutrophil elastase (NE), a granule-associated enzyme, participates in connective tissue breakdown and promotes cytokine release and specific receptor activation during various inflammatory diseases like RA. NE is increased in the SF and cartilage of RA patients and represents a target for the development of new therapeutic possibilities. The present research aimed to evaluate the preclinical pharmacological profile of the N-benzoylpyrazole derivative EL-17, a potent and selective NE inhibitor, in a rat model of RA. METHODS Complete Freund's Adjuvant (CFA) was injected in the tibiotarsal joint and the effect of acute or repeated treatments with EL-17 (1-30 mg/kg by mouth) were evaluated. RESULTS On day 14 after CFA injection, a single administration of EL-17 significantly reduced CFA-dependent hypersensitivity to mechanical noxious stimuli and the postural unbalance related to spontaneous pain. To evaluate the preventive efficacy, EL-17 was administered daily starting from the day of CFA treatment. Behavioural measurements performed on days 7 and 14 showed a progressive efficacy of EL-17 against hypersensitivity to mechanical noxious and non-noxious stimuli, as well as a decrease of hind limb weight-bearing alterations. Histological evaluation of the tibiotarsal joint (day 14) demonstrated significant prevention of articular derangement after EL-17 (30 mg/kg) treatment. The protective effects of EL-17 directly correlated with a complete reversion of the plasma NE activity increase induced by CFA. CONCLUSIONS The NE inhibitor EL-17 relieved articular pain after acute administration. Furthermore, repeated treatment reduced the development of hypersensitivity and protected joint tissue, revealing a disease-modifying profile.

Abstract
Clearance of apoptotic debris is a vital role of the innate immune system. Drawing upon principles of apoptotic clearance, convenient delivery vehicles including intrinsic anti-inflammatory characteristics and specificity to immune cells can be engineered to aid in drug delivery. In this article, we examine the use of phosphatidylserine (PtdSer), the well-known "eat-me" signal, in nanoparticle-based therapeutics making them highly desirable "meals" for phagocytic immune cells. Use of PtdSer facilitates engulfment of nanoparticles allowing for imaging and therapy in various pathologies and may result in immunomodulation. Furthermore, we discuss the targeting of the macrophages and other cells at sites of inflammation in disease. A thorough understanding of the immunobiology of "eat-me" signals is requisite for the successful application of "eat-me"-bearing materials in biomedical applications.

Abstract
There is a growing interest in the development of organic nanomaterials for biomedical applications. An increasing number of studies focus on the uses of nanomaterials with organic structure for regeneration of bone, cartilage, skin or dental tissues. Solid evidence has been found for several advantages of using natural or synthetic organic nanostructures in a wide variety of dental fields, from implantology, endodontics, and periodontics, to regenerative dentistry and wound healing. Most of the research is concentrated on nanoforms of chitosan, silk fibroin, synthetic polymers or their combinations, but new nanocomposites are constantly being developed. The present work reviews in detail current research on organic nanoparticles and their potential applications in the dental field.

Abstract
Lenz-Majewski syndrome (LMS) is a rare disease presenting with complex physical and mental abnormalities. Whole exome sequencing performed on five LMS-affected individuals has identified gain-of-function mutations in the PTDSS1 gene encoding phosphatidylserine synthase 1 (PSS1) enzyme. These mutations all rendered PSS1 insensitive to PS-mediated product inhibition. In a recent study we showed that uncontrolled PS production by these mutant PSS1 enzymes lead to the accumulation of PS in the ER where it is not detected in normal cells. This increased PS in the ER in turn, activated the Sac1 phosphatase, which is responsible for the dephosphorylation of the minor lipid, phosphatidylinositol 4-phosphate (PI4P) in the ER. Increased Sac1 activity decreased PI4P levels both in the Golgi and the plasma membrane thereby dissipating the PI4P gradients set up by PI 4-kinase enzymes (PI4Ks) between these membranes and the ER. Such PI4P gradients at membrane contact sites have been shown to support the transports of structural lipids such as cholesterol and PS out of the ER by non-vesicular lipid transfer. Therefore, uncontrolled production of PS not only affects the PS status of cells but also initiates an avalanche of changes in the metabolism of other membrane lipids via affecting PI4P gradients throughout the cell. Recognition of the close metabolic interaction between PS synthesis and PI4P metabolism provided a new clue to better understand the molecular underpinning of this rare and severe disease.

Abstract
Background Phosphatidylserine-containing liposomes (PSL) have been shown to reduce inflammation in experimental models of acute arthritis, by mimicking the apoptotic process. The aim of this study was to evaluate the effect of pegylated PSL (PEG-PSL) on chronic inflammation of collagen induced arthritis (CIA) in DBA/1J mice. Methods CIA was induced in 24 DBA/1J mice (n = 6/group), which were divided into control (0.9 % saline) or treated with PEG-PSL (5, 10 and 15 mg/kg/day, subcutaneously for 20 days). Clinical score, limb histology and measurement of cytokines in knee joints of animals by ELISA and cytometric bead array (CBA) were evaluated. The in vitro study employed macrophage cultures stimulated with 100 ng/ml of LPS plus 10 ng/ml of PMA and treated with 100 μM PEG-PSL. Results Resolution of the disease in vivo and the inflammatory process in vitro were not observed. PEG-PSL, in doses of 10 and 15 mg/kg, were not shown to reduce the score of the disease in animals, whereas with the dose of 5 mg/kg, the animals did not show the advanced stage of the disease when compared to the controls. The PEG- PSL 5, 10 and 15 mg/kg treatment groups did not show significant reduction of TNF-α, IL-1β, IL-6, IL-2 and IFN-γ when compared to the controls. Disease incidence and animal weights were not affected by treatment. Regarding the paw histology, PEG-PSL did not yield any reductions in the infiltrating mononuclear, synovial hyperplasia, extension of pannus formation, synovial fibrosis, erosion of cartilage, bone erosion or cartilage degradation. The concentration of 100 μM of PEG-PSL has not been shown to reduce inflammation induced by LPS/PMA in the in vitro study. Treated groups did not show any reduction in inflammatory cytokines in the knee joints of animals affected by the disease compared to the control, although there were higher concentrations of TGF-β1 in all experimental groups. Conclusion The experimental model showed an expression of severe arthritis after the booster. TGF-β1 as well other pro inflammatory cytokines were presented in high concentrations in all groups. PEG-PSL had no impact on the clinical score, the histopathology from tibial-tarsal joints or the production of cytokines in the knee joints. Other alternatives such as dosage, route of administration, and as an adjunct to a drug already on the market, should be evaluated to support the use of PEG-PSL as a new therapeutic tool in inflammatory diseases.

Use of autoantigen-loaded phosphatidylserine-liposomes to arrest autoimmunity in type 1 diabetes. PLoS One 2015; 10:e0127057. [PMID: 26039878 PMCID: PMC4454589 DOI: 10.1371/journal.pone.0127057] [Citation(s) in RCA: 57] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/03/2014] [Accepted: 04/10/2015] [Indexed: 01/10/2023] Open
Abstract
Introduction The development of new therapies to induce self-tolerance has been an important medical health challenge in type 1 diabetes. An ideal immunotherapy should inhibit the autoimmune attack, avoid systemic side effects and allow β-cell regeneration. Based on the immunomodulatory effects of apoptosis, we hypothesized that apoptotic mimicry can help to restore tolerance lost in autoimmune diabetes. Objective To generate a synthetic antigen-specific immunotherapy based on apoptosis features to specifically reestablish tolerance to β-cells in type 1 diabetes. Methods A central event on the surface of apoptotic cells is the exposure of phosphatidylserine, which provides the main signal for efferocytosis. Therefore, phosphatidylserine-liposomes loaded with insulin peptides were generated to simulate apoptotic cells recognition by antigen presenting cells. The effect of antigen-specific phosphatidylserine-liposomes in the reestablishment of peripheral tolerance was assessed in NOD mice, the spontaneous model of autoimmune diabetes. MHC class II-peptide tetramers were used to analyze the T cell specific response after treatment with phosphatidylserine-liposomes loaded with peptides. Results We have shown that phosphatidylserine-liposomes loaded with insulin peptides induce tolerogenic dendritic cells and impair autoreactive T cell proliferation. When administered to NOD mice, liposome signal was detected in the pancreas and draining lymph nodes. This immunotherapy arrests the autoimmune aggression, reduces the severity of insulitis and prevents type 1 diabetes by apoptotic mimicry. MHC class II tetramer analysis showed that peptide-loaded phosphatidylserine-liposomes expand antigen-specific CD4+ T cells in vivo. The administration of phosphatidylserine-free liposomes emphasizes the importance of phosphatidylserine in the modulation of antigen-specific CD4+ T cell expansion. Conclusions We conclude that this innovative immunotherapy based on the use of liposomes constitutes a promising strategy for autoimmune diseases.

Abstract
Bone is sensitive to overactive immune responses, which initiate the onset of inflammatory bone disorders, such as rheumatoid arthritis and periodontitis, resulting in a significant systemic inflammatory response. On the other hand, neuroinflammation is strongly implicated in Alzheimer's disease (AD), which can be enhanced by systemic inflammation, such as that due to cardiovascular disease and diabetes. There is growing clinical evidence supporting the concept that rheumatoid arthritis and periodontitis are positively linked to AD, suggesting that inflammatory bone disorders are risk factors for this condition. Recent studies have suggested that leptomeningeal cells play an important role in transducing systemic inflammatory signals to brain-resident microglia. More importantly, senescent-type, but not juvenile-type, microglia provoke neuroinflammation in response to systemic inflammation. Because the prevalence of rheumatoid arthritis and periodontitis increases with age, inflammatory bone disorders may be significant sources of covert systemic inflammation among elderly people. The present review article highlights our current understanding of the link between inflammatory bone disorders and AD with a special focus on microglia aging.

Abstract
Lenz-Majewski hyperostotic dwarfism (LMHD) is an ultra-rare Mendelian craniotubular dysostosis that causes skeletal dysmorphism and widely distributed osteosclerosis. Biochemical and histopathological characterization of the bone disease is incomplete and nonexistent, respectively. In 2014, a publication concerning five unrelated patients with LMHD disclosed that all carried one of three heterozygous missense mutations in PTDSS1 encoding phosphatidylserine synthase 1 (PSS1). PSS1 promotes the biosynthesis of phosphatidylserine (PTDS), which is a functional constituent of lipid bilayers. In vitro, these PTDSS1 mutations were gain-of-function and increased PTDS production. Notably, PTDS binds calcium within matrix vesicles to engender hydroxyapatite crystal formation, and may enhance mesenchymal stem cell differentiation leading to osteogenesis. We report an infant girl with LMHD and a novel heterozygous missense mutation (c.829T>C, p.Trp277Arg) within PTDSS1. Bone turnover markers suggested that her osteosclerosis resulted from accelerated formation with an unremarkable rate of resorption. Urinary amino acid quantitation revealed a greater than sixfold elevation of phosphoserine. Our findings affirm that PTDSS1 defects cause LMHD and support enhanced biosynthesis of PTDS in the pathogenesis of LMHD.

Abstract
Spondyloarthritis (SpA) is a group of inflammatory rheumatic diseases whose main clinical feature is inflammation of the axial spine. Articular, periarticular, and extra-articular manifestations can also occur, depending on the type of spondyloarthritis. The most common clinical subsets of SpA are ankylosing spondylitis (AS) and psoriatic arthritis (PsA). SpA is a major health challenge given the propensity to affect young adults and the potential requirement for lifelong treatment. Although the precise etiology of SpA is unknown, there is mounting evidence that these diseases are a result of complex interplay of genetic, environmental, and immunological factors. In this review on SpA, we will discuss genetic variants with genome-wide significance, highlight potential clinical application of genetic variants, and discuss challenges in further elucidating the genetic basis of SpA.

Abstract
Lenz-Majewski syndrome (LMS) is a syndrome of intellectual disability and multiple congenital anomalies that features generalized craniotubular hyperostosis. By using whole-exome sequencing and selecting variants consistent with the predicted dominant de novo etiology of LMS, we identified causative heterozygous missense mutations in PTDSS1, which encodes phosphatidylserine synthase 1 (PSS1). PSS1 is one of two enzymes involved in the production of phosphatidylserine. Phosphatidylserine synthesis was increased in intact fibroblasts from affected individuals, and end-product inhibition of PSS1 by phosphatidylserine was markedly reduced. Therefore, these mutations cause a gain-of-function effect associated with regulatory dysfunction of PSS1. We have identified LMS as the first human disease, to our knowledge, caused by disrupted phosphatidylserine metabolism. Our results point to an unexplored link between phosphatidylserine synthesis and bone metabolism.

Abstract
Liposomes containing phosphatidylserine (PSL) produce PGE2 after being phagocytosed by microglia, but the precise underlying mechanism behind it still remains unclear. Here, we showed that liposomes consisting of phosphatidylserine and lysophosphatidylcholine, a lipolysis product of phosphatidylcholine by PLA2, were phagocytosed by microglia, but failed to induce secretion of PGE2. Furthermore, PSL-induced PGE2 secretion was significantly inhibited by MJ33, an aiPLA2 inhibitor, but not by AACOCF3, a cPLA2 inhibitor. PSL also produced PGD2 and 15d-PGJ2 in microglia. We thus hypothesize that free arachidonic acid is supplied through aiPLA2-mediated lipolysis of phagocytosed phosphatidylcholine, leading to the production of PGH2 and its downstream metabolites.

Abstract
Ankylosing spondylitis (AS) and spondyloarthritis are strongly genetically determined. The long-standing association with HLA-B27 is well described, although the mechanism by which that association induces AS remains uncertain. Recent developments include the description of HLA-B27 tag single nucleotide polymorphisms in European and Asian populations. An increasing number of non-MHC genetic associations have been reported, which provided amongst other things the first evidence of the involvement of the IL-23 pathway in AS. The association with ERAP1 is now known to be restricted to HLA-B27 positive disease. Preliminary studies on the genetics of axial spondyloarthritis demonstrate a lower HLA-B27 carriage rate compared with AS. Studies with larger samples and including non-European ethnic groups are likely to further advance the understanding of the genetics of AS and spondyloarthritis.

Abstract
Phosphatidylserine (PS)-containing liposomes (PSLs) strongly inhibit inflammatory bone loss in adjuvant arthritic (AA) rats. This effect was attributed to the inhibition of osteoclastogenesis through the secretion of prostaglandin E(2) and transforming growth factor-β1 by osteoclast precursors after the phagocytosis of PSLs. However, infiltrated macrophages are considered to secrete anti-inflammatory mediators after phagocytosis of PSLs, which also contribute to inhibiting osteoclastogenesis. In the present study, we have attempted to elucidate the effects of PSLs on the phenotype of infiltrated macrophages during inflammatory bone loss. In AA rats, the ankle joints swelled with the infiltration of both macrophages and helper T cells into the synovium after a complete Freund's adjuvant injection. In the ankle joints of AA rats, approximately half of the infiltrated macrophages underwent a phenotypic change from interleukin (IL)-1β-producing to IL-10-producing cells after the phagocytosis of PSLs. In lipopolysaccharide (LPS)-stimulated macrophages, PSLs also significantly decreased IL-1β production, but increased IL-10 production. Moreover, PSLs inhibited the rapid activation of p38 mitogen-activated protein kinases (MAPK) and nuclear factor (NF)-κB, but enhanced the delayed activation of extracellular signal-regulated kinase (ERK) in LPS-stimulated macrophages. PSL-induced different influence on the activities of p38 MAPK and ERK is a likely underlying mechanism for phenotypic change of infiltrated macrophages after the phagocytosis of PSLs. This phenotypic change may be responsible for a significant decrease in the mean mRNA level of the receptor activator of NF-κB (RANK) and the RANK ligand (RANKL) in the ankle joint of PSL-treated AA rats, resulting in the inhibition of inflammatory bone loss.
