Abstract
BACKGROUND 6-acetylacteoside (6-AA) is a phenylethanoid glycoside isolated from Cistanche deserticola which had been previously proven to possess anti-osteoporotic activity previously. Currently, it is still unknown whether 6-AA plays a crucial role on the anti-osteoporotic effects of C. deserticola. PURPOSE To elucidate the therapeutic effect and mechanism of 6-AA on osteoporosis by employing an ovariectomized mouse model in vivo and RAW264.7 cells in vitro. METHODS Sixty female ICR mice were randomly assigned into six groups: sham-operated control group (SHAM, vehicle), ovariectomized model group (OVX, vehicle), positive group (EV, 1 mg/kg/day of estradiol valerate), low dosage (10 mg/kg/day of 6-AA), medium dosage (20 mg/kg/day of 6-AA) and high dosage (40 mg/kg/day of 6-AA) treatment groups. All substances were administered daily by intragastric gavage. After 12 weeks of intervention, trabecular bone microarchitecture was estimated and bone biomechanics were determined. Bone formation and resorption factors were determined by using the corresponding Elisa kits. The related proteins and metabolites were estimated by using western-blot and metabolomics techniques. RESULTS OVX mice demonstrated significant atrophy of the uterine and vagina, declined biomechanical parameters such as flexural strength and maximum load, deteriorated trabecular bone microarchitecture such as decreased BMD, BMC, TMC, TMD, BVF, Tb. N, and Tb. Th and increased Tb. Sp, as well as increased bone resorption factors such as TRAP, cathepsin K, and DPD, all after 12 weeks of ovariectomy operation. Following administration of 6-AA to OVX mice, parameters related to the bone microarchitecture, bone resorption activities as well as biomechanical properties were all significantly improved. Meanwhile, the levels of NF-κB, NFATc1, RANK, RANKL and TRAF6 were significantly downregulated, while OPG, PI3K and AKT were upregulated after 6-AA intervention. This indicates that, 6-AA could prevent bone resorption by regulating the RANKL/RANK/OPG mediated NF-κB and PI3K/AKT pathways. Furthermore, 26 different metabolites corresponding to 25 metabolic pathways were identified, and 5 of which were related to the formation of osteoporosis. Interestingly, 23 abnormal metabolites were recovered after 6-AA treatment. CONCLUSION Our results revealed the significant anti-osteoporotic effects of 6-AA on ovariectomized mice which were probably exerted via suppression of osteoclast formation and bone resorption.

Abstract
The skeletal system and immune system seem to be two independent systems. However, there in fact are extensive and multiple crosstalk between them. The concept of osteoimmunology was created to describe those interdisciplinary events, but it has been constantly updated over time. In this review, we summarize the interactions between the skeletal and immune systems in the co-development of the two systems and the progress of certain typical bone abnormalities and bone regeneration on the cellular and molecular levels according to the mainstream novel study. At the end of the review, we also highlighted the possibility of extending the research scope of osteoimmunology to other systemic diseases. In conclusion, we propose that osteoimmunology is a promising perspective to uncover the mechanism of related diseases; meanwhile, a study from the point of view of osteoimmunology may also provide innovative ideas and resolutions to achieve the balance of internal homeostasis.

Abstract
Osteoporosis has been classically considered a comorbidity of rheumatoid arthritis (RA). However, recent advances in the pathogenesis of osteoporosis in RA have shown a close interplay between cells of the immune system and those involved in bone remodeling, introducing new actors into the classic route in which osteoclast activation is related to the RANK/RANKL/OPG pathway. In fact, the inflammatory state in early stages of RA, mediated by interleukin (IL)-1, IL-6, IL-8 and tumor necrosis factor (TNF)-α has the ability to activate and differentiate osteoclasts not only through their relationship with RANKL, but also through the Wnt/DKK1/sclerostin pathway, leading to bone loss. The role of synovial fibroblasts and activated T lymphocytes in the expression of the RANKL system and its connection to bone destruction is also depicted. In addition, autoantibodies such as rheumatoid factor and anti-citrullinated protein antibodies are other pathogenic mechanisms for the development of bone erosions and systemic osteoporosis in RA, even before the onset of arthritis. The aim of this review is to unravel the relationship between different factors involved in the development of osteoporosis in RA patients, both the classic factors and the most novel, based on the relationship of autoantibodies with bone remodeling. Furthermore, we propose that bone mineral density measured by different techniques may be helpful as a biomarker of severity in early arthritis patients.

Abstract
RANKL and RANK are expressed in different cell types and tissues throughout the body. They were originally described for their essential roles in bone remodeling and the immune system but have subsequently been shown to provide essential signals from regulating mammary gland homeostasis during pregnancy to modulating tumorigenesis. The success of RANKL/RANK research serves as a paragon for translational research from the laboratory to the bedside. The case in point has been the development of Denosumab, a RANKL-blocking monoclonal antibody which has already helped millions of patients suffering from post-menopausal osteoporosis and skeletal related events in cancer. Here we will provide an overview of the pathway from its origins to its clinical relevance in disease, with a special focus on emerging evidence demonstrating the therapeutic value of targeting the RANKL/RANK/OPG axis not only in breast cancer but also as an addition to the cancer immunotherapy arsenal.

Abstract
Fibroblast-derived exosomes have been reported to transfer microRNAs to recipient cells, where they regulate target gene expression, which is of interest for understanding the basic biology of inflammation, tissue homeostasis, and development of therapeutic approaches. Initial microarray-based analysis carried out in this study identified the rheumatoid arthritis (RA)-related differentially expressed gene pyruvate dehydrogenase kinase 4 (PDK4). Subsequently, the upstream regulatory microRNA-106b (miR-106b) of PDK4 was predicted with bioinformatic analyses. A collagen-induced arthritis (CIA)-induced mouse model was established, and exosomes were isolated from synovial fibroblasts (SFs) and transferred into chondrocytes to identify the role of exosomes in rheumatoid arthritis (RA). We found that PDK4 was poorly expressed in RA cartilage tissues and chondrocytes, while miR-106b was highly expressed in RA SFs and SF-derived exosomes. Notably, PDK4 was confirmed as a target gene of miR-106b. Over-expression of PDK4 promoted the proliferation and migration abilities of chondrocytes and inhibited their apoptosis as well as affected the receptor activator of nuclear factor kappa B ligand (RANKL)/RANK/osteoprotegerin (OPG) system. Meanwhile, miR-106b was delivered from SFs to chondrocytes through exosomes, which suppressed chondrocyte proliferation and migration and accelerated apoptosis as well as affected the RANKL/RANK/OPG system via down-regulation of PDK4. Furthermore, in vivo results validated that miR-106b inhibition could relieve CIA-induced RA. Taken together, SF-derived exosomal miR-106b stimulates RA initiation by targeting PDK4, indicating a physiologically validated potential approach for the prevention and treatment of RA. KEY MESSAGES: PDK4 is decreased in chondrocytes of RA, while miR-106b is increased in SFBs. PDK4 promotes proliferation and migration of chondrocytes. miR-106b could target 3'UTR of PDK4 gene. SFB-exosomal miR-106b inhibits proliferation and migration of chondrocytes. Inhibition of miR-106b attenuates RA progression in a CIA mouse model.

Abstract
Zoledronic acid (ZOL), a nitrogen bisphosphonate (N-BP), is currently used to treat and control pediatric osteolytic diseases. Variations in the intensity of the effects and side effects of N-BPs have been reported with no clear explanations regarding their origins. We wonder if such variations could be associated with different levels of RANKL signaling activity in growing bone during and after the treatment with N-BPs. To answer this question, ZOL was injected into neonate C57BL/6J mice with different genetically-determined RANKL signaling activity levels (Opg+/+\RankTg-, Opg+/+\RankTg+, Opg+/-\RankTg-, Opg+/-\RankTg+, Opg-/-\RankTg- and Opg-/-\RankTg+ mice) following a protocol (4 injections from post-natal day 1 to 7 at the dose of 50 μg/kg) that mimics those used in onco-pediatric patients. At the end of pediatric growth (1 and half months) and at an adult age (10 months), the bone morphometric and mineral parameters were measured using μCT in the tibia and skull for the different mice. A histologic analysis of the dental and periodontal tissues was also performed. At the end of pediatric growth, a delay in long bone and skull bone growth, a blockage of tooth eruption, some molar root alterations and a neoplasia-like structure associated with incisor development were found. Interestingly, the magnitude of these side effects was reduced by Opg deficiency (Opg-/-) but increased by Rank overexpression (RankTg). Analysis of the skeletal phenotype at ten months confirmed respectively the beneficial and harmful effects of Opg deficiency and Rank overexpression. These results validated the hypothesis that the RANKL signaling activity level in the bone microenvironment is implicated in the modulation of the response to ZOL. Further studies will be necessary to understand the underlying molecular mechanisms, which will help decipher the variability in the effects of N-BPs reported in the human population. SIGNIFICANT STATEMENTS: The present study establishes that in mice the RANKL signaling activity level is a major modulator of the effects and side-effects of bisphosphonates on the individual skeleton during growth. However, the modulatory actions are dependent on the ways in which this level of activity is increased. A decrease in OPG expression is beneficial to the skeletal phenotype observed at the end of growth, while RANK overexpression deteriorates it. Far removed from pediatric treatment, in adults, the skeletal phenotypes initially observed at the end of growth for the different levels of RANKL signaling activity were maintained, although significant improvement was associated only with reductions in OPG expression.

Abstract
Vitamin D has an anabolic effect on bone developmental processes and is involved in maintaining skeletal integrity. In recent years, pediatric cases of vitamin D intoxication have attracted attention. Therefore, the aim of this study was to investigate the influence of long-term administration of physiologically-high-dose calcitriol (1,25(OH)2D3) on bone remodeling in young developing rats. Neonatal rats received once-daily subcutaneous injection of calcitriol (250 ng/kg body weight), or PBS only as a control, for 3 weeks. At 1, 2 and 4 weeks' post-administration, rats were sacrificed and fixed by transcardial perfusion with 4 % paraformaldehyde, following which tibiae were extracted for histochemical analysis. Compared with the control group, the number of tartrate-resistant acid phosphatase- and Cathepsin K-positive osteoclasts were significantly increased, and the expression of alkaline phosphatase in osteoblasts was decreased in trabecular bone of rats administered high-dose 1,25(OH)2D3, leading to decreased trabecular bone volume. In addition, the expression of receptor activator of nuclear factor kappa-B ligand (RANKL) was increased, while that of osteoprotegerin was weaker in osteoblasts in the experimental group compared with the control group. Moreover, there was weaker immunoreactivity for EphrinB2 in osteoclasts and EphB4 in osteoblasts of trabecular bone in the experimental group compared with the control group. These findings suggest that long-term use of physiologically-high dose calcitriol may result in bone loss through RANKL/RANK/osteoprotegerin and EphrinB2-EphB4 signaling pathways, and that these negative effects could continue after drug withdrawal. Therefore, optimal limits for vitamin D administration need to be established for children and adolescents.
