Abstract
Macrophage activation syndrome (MAS) is a life-threatening condition, characterized by cytopenia, multi-organ dysfunction, and coagulopathy associated with excessive activation of macrophages. In this study, we investigated the roles of alpha2-antiplasmin (α2AP) in the progression of MAS using fulminant MAS mouse model induced by toll-like receptor-9 agonist (CpG) and D-(+)-galactosamine hydrochloride (DG). α2AP deficiency attenuated macrophage accumulation, liver injury, and fibrin deposition in the MAS model mice. Interferon-γ (IFN-γ) is associated with macrophage activation, including migration, and plays a pivotal role in MAS progression. α2AP enhanced the IFN-γ-induced migration, and tissue factor production. Additionally, we showed that fibrin-induced macrophage activation and tumor necrosis factor-α production. Moreover, the blockade of α2AP by neutralizing antibodies attenuated macrophage accumulation, liver injury, and fibrin deposition in the MAS model mice. These data suggest that α2AP may regulate IFN-γ-induced responses and be associated with macrophage activation and fibrin deposition in the MAS progression.

Abstract
Fibrotic diseases, such as systemic sclerosis (SSc), idiopathic pulmonary fibrosis, renal fibrosis and liver cirrhosis are characterized by tissue overgrowth due to excessive extracellular matrix (ECM) deposition. Fibrosis progression is caused by ECM overproduction and the inhibition of ECM degradation due to several events, including inflammation, vascular endothelial dysfunction, and immune abnormalities. Recently, it has been reported that urokinase plasminogen activator (uPA) and its receptor (uPAR), known to be fibrinolytic factors, orchestrate the inflammatory response, vascular homeostasis, and immune homeostasis system. The uPA/uPAR system may show promise as a potential therapeutic target for fibrotic diseases. This review considers the role of the uPA/uPAR system in the progression of fibrotic diseases.

Abstract
Systemic sclerosis (SSc) is a connective tissue disease of autoimmune origin characterized by vascular dysfunction and extensive fibrosis of the skin and visceral organs. Vascular dysfunction is caused by endothelial cell (EC) apoptosis, defective angiogenesis, defective vasculogenesis, endothelial-to-mesenchymal transition (EndoMT), and coagulation abnormalities, and exacerbates the disease. Fibrinolytic regulators, such as plasminogen (Plg), plasmin, α2-antiplasmin (α2AP), tissue-type plasminogen activator (tPA), urokinase-type plasminogen activator (uPA) and its receptor (uPAR), plasminogen activator inhibitor 1 (PAI-1), and angiostatin, are considered to play an important role in the maintenance of endothelial homeostasis, and are associated with the endothelial dysfunction of SSc. This review considers the roles of fibrinolytic factors in vascular dysfunction of SSc.

Abstract
Introduction Chronic inflammatory diseases such as rheumatoid arthritis and periodontitis frequently cause bone destruction. Inflammation‐induced bone loss results from the increase of bone‐resorbing osteoclasts. Recently, we demonstrated that urokinase type plasminogen activator (uPA) suppressed lipopolysaccaride (LPS)‐inflammatory osteoclastogenesis through the adenosine monophosphate‐activated protein kinase (AMPK) pathway, whereas its receptor (uPAR) promoted that through the Akt pathway. Methods We investigated the effects of uPA‐derived peptide (Å6) in the LPS‐induced inflammatory osteoclastogenesis and bone destruction. Results We found that Å6 attenuated inflammatory osteoclastogenesis and bone loss induced by LPS in mice. We also showed that Å6 attenuated the LPS‐promoted inflammatory osteoclastogenesis by inactivation of NF‐κB in RAW264.7 mouse monocyte/macrophage lineage cells. Furthermore, we showed that Å6 attenuated the Akt phosphorylation, and promoted the AMPK phosphorylation. Conclusion Å6 is involved in the suppression of LPS‐promoted inflammatory osteoclastgensis and bone destruction by regulating the AMPK and Akt pathways. These findings provide a basis for clinical strategies to improve the bone loss caused by inflammatory diseases.

Abstract
Introduction Chronic inflammatory diseases, such as rheumatoid arthritis and periodontitis, cause the bone destruction by promotion of the differentiation of monocyte/macrophage lineage cells into mature osteoclasts (OCs) with active bone‐resorbing character. However, the detailed mechanisms underlying this disorder remain unclear. We herein investigated the role of urokinase plasminogen activator receptor (uPAR) in the bone destruction caused by chronic inflammation. Methods We investigated that the effect of uPAR on inflammatory OC formation induced by lipopolysaccharide (LPS) in inflammatory diseases. Results We found that the LPS more weakly induced OC formation and the resultant bone loss in uPAR‐deficient mice than in wild‐type mice. Additionally, we demonstrated that uPAR significantly potentiated LPS‐induced OC formation of RAW264.7 mouse monocyte/macrophage linage cells in integrin β3/Akt‐dependent manner. Moreover, we showed that the blocking of uPAR function by the administration of anti‐uPAR neutralizing antibody significantly attenuated the LPS‐induced OC formation and the resultant bone loss in mice. Conclusions These results strongly suggest that uPAR negatively regulates the LPS‐induced inflammatory OC formation and the resultant bone loss mediated through the integrin β3/Akt pathway. Our findings partly clarify the molecular mechanisms underlying bone destruction caused by chronic inflammatory diseases, and would benefit research on identifying antibody therapy for the treatment of these diseases.

Abstract
Introduction Mesenchymal stem cells (MSC) are well described for their role in tissue regeneration following injury. Migratory properties of endogenous or administrated MSC are critical for tissue repair processes. Platelet-derived growth factor (PDGF) is a chemotactic growth factor that elicits mesenchymal cell migration. However, it is yet to be elucidated if signaling pathways other than direct activation of PDGF receptor (PDGF-R) are involved in PDGF-induced cell migration. Methods Knocking down and co-immunoprecipitation approaches were used to evaluate urokinase-type plasminogen activator receptor (uPAR) requirement and its interactions with proteins involved in migration mechanisms, in human MSC induced to migrate under PDGF-AB effect. Results We demonstrated that uPAR activation and its association with β1-integrin are required for PDGF-AB-induced migration. This phenomenon takes place in MSC derived from bone marrow and from adipose tissue. Conclusions We showed that PDGF-AB downstream signaling requires other effector molecules in MSC such as the uPA/uPAR system and β1 integrin signaling pathway known for their role in migration. These findings provide new insights in molecular mechanisms of PDGF-AB-induced migration of human MSC that may be relevant to control MSC function and tissue remodeling after injury.

Abstract
The urokinase-type plasminogen activator receptor (uPAR) is a glycosylphosphatidylinositol-anchored membrane protein with multiple functions. In the present study, we examined whether the uPAR plays any role in the regulation of glucose metabolism. The experiments were performed using male wild-type (uPAR) and uPAR knockout (uPAR) C57BL/6J mice. The blood glucose levels after the intraperitoneal injection of glucose were significantly decreased in uPAR mice compared with uPAR mice. On the other hand, there were no differences in the insulin secretion induced by glucose injection and the reactivity of insulin between uPAR and uPAR mice. The expression levels of glucose transporter 2 (GLUT2) in the liver and GLUT4 in the skeletal muscles from the uPAR mice were significantly increased compared with those of the uPAR mice. In addition, we found that the level of phosphorylation of AMP-activated protein kinase in skeletal muscles and myoblasts from the uPAR mice increased compared with those in uPAR mice. These data suggest that the increase in the GLUT2 and GLUT4 expression and the activation of AMP-activated protein kinase by uPAR deficiency enhances the glucose intake. These findings therefore provide new insights into the role of uPAR in the glucose metabolism.

Abstract
The contribution of plasminogen (Plg)/plasmin, which have claimed to be the main fibrinolytic regulators in the bone metabolism, remains unclear. This study evaluated how the absence of Plg affects the function of osteoblast (OB) and osteoclast (OC). There was a larger population of pre-OCs in bone marrow-derived cells from the Plg(-/-) mice than the population of that from the WT mice. In addition, the absence of Plg suppressed the expression of osteoprotegerin in OBs. Moreover, an exogenous plasmin clearly induced the osteoprotegerin expression in Plg(-/-) OBs. The osteoclastogenesis of RAW264.7 mouse monocyte/macrophage lineage cells in co-culture with OBs from the Plg(-/-) mice was significantly accelerated in comparison with that in co-culture with OBs from the WT mice. Intriguingly, the accelerated OC differentiation of RAW264.7 cells co-cultured with Plg(-/-) OBs was clearly suppressed by the treatment of an exogenous plasmin. Consequently, Plg(-/-) mice display decreased bone mineral density. These findings could eventually lead to the development of new clinical therapies for bone disease caused by a disorder of the fibrinolytic system.

Abstract
Benzylideneacetophenone analogues are known to have several significant biological activities, including antiinflammatory, antitumor, antibacterial, antiviral, and gastric-protective activities. However, the antiproliferative effects of benzylideneacetophenone analogues on vascular smooth muscle cells (VSMCs) are unknown. The aim of this study was to elucidate the antiproliferative effects and molecular mechanism of BST406, a newly synthesized benzylideneacetophenone derivative, on platelet-derived growth factor (PDGF)-BB-stimulated rat aortic VSMCs. BST406 inhibited [(3)H]-thymidine incorporation into DNA in VSMCs following treatment with PDGFBB 25 ng/ml. PDGF-BB-stimulated DNA synthesis was significantly reduced. Moreover, pretreatment with BST406 (0-10microM) suppressed the proliferation of PDGF-BB-stimulated cells in a concentration-dependent manner. We also investigated the mechanism of the antiproliferative effects of BST406 in PDGF-BB-stimulated VSMCs. In Western blot analysis, PDGF-BB-stimulated (25 ng/ml) phospholipase-C (PLC)gamma1 and Akt phosphorylation was inhibited by BST406 (0-10microM). However, BST406 did not inhibit the PDGF-receptor beta-chain (PDGF-Rbeta) and extracellular-regulated kinase 1 and 2 (ERK1/2) phosphorylation induced by PDGF-BB. To confirm that the inhibitory effects of BST406 are mediated through the inhibition of PLCgamma1 or Akt, the effects of inhibitors on cell viability were examined. U73122 completely inhibited PDGF-BB-induced proliferation of VSMCs. However, LY294002 10microM had no significant effects on PDGF-BB-induced proliferation. These findings suggest that the inhibitory effects of BST406 on the proliferation of PDGF-BB-stimulated VSMCs are mediated by suppression of the PLCgamma1 signaling pathways. Our observations may explain, in part, the mechanistic basis for the prevention of cardiovascular disease (such as atherosclerosis and restenosis after coronary angioplasty) by BST406.
