Abstract
Apoptosis plays an essential role in the pathophysiologic processes of rheumatoid arthritis. A molecular probe that allows spatiotemporal observation of apoptosis in vitro, in vivo, and ex vivo concomitantly would be useful to monitoring or predicting pathophysiologic stages. In this study we investigated whether cyclic apoptosis-targeting peptide-1 (CApoPep-1) can be used as an apoptosis imaging probe in inflammatory arthritis. We tested the utility of CApoPep-1 for detecting apoptotic immune cells in vitro and ex vivo using flow cytometry and immunofluorescence. The feasibility of visualizing and quantifying apoptosis using this probe was evaluated in a murine collagen-induced arthritis (CIA) model, especially after treatment. CApoPep-1 peptide may successfully replace Annexin V for in vitro and terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assay for ex vivo in the measurement of apoptotic cells, thus function as a sensitive probe enough to be used clinically. In vivo imaging in CIA mice revealed that CApoPep-1 had 42.9 times higher fluorescence intensity than Annexin V for apoptosis quantification. Furthermore, it may be used as an imaging probe for early detection of apoptotic response in situ after treatment. The CApoPep-1 signal was mostly co-localized with the TUNEL signal (69.6% of TUNEL+ cells) in defined cell populations in joint tissues of CIA mice. These results demonstrate that CApoPep-1 is sufficiently sensitive to be used as an apoptosis imaging probe for multipurpose applications which could detect the same target across in vitro, in vivo, to ex vivo in inflammatory arthritis.

Abstract
Objective Therapeutic agents that are transformable via introducing cleavable linkage by locally enriched MMP-2 within inflamed synovium would enhance therapeutic efficacy on chronic inflammatory arthritis. Transforming growth factor-β-inducible gene-h3 (βig-h3), which consists of four fas-1 domains and an Arg-Gly-Asp (RGD) motif, intensifies inflammatory processes by facilitating adhesion and migration of fibroblast-like synoviocyte in the pathogenesis of rheumatoid arthritis (RA). The aim of this study was to investigate whether a MMP-2-cleavable peptide complex consisting of a fas-1 domain and an RGD peptide blocks the interaction between βig-h3 and resident cells and leads to the amelioration of inflammatory arthritis. Methods We designed βig-h3-derivatives, including the fourth fas-1 domain truncated for H1 and H2 sequences of mouse (MFK00) and MMP-2-cleavable peptide complex (MFK902). MMP-2 selectivity was examined by treatment with a series of proteases. MFK902 efficacy was determined by the adhesion and migration assay with NIH3T3 cells in vitro and collagen-induced arthritis (CIA) model using male DBA/1J mice in vivo. The mice were treated intraperitoneally with MFK902 at different dosages. Results MFK902 was specifically cleaved by active MMP-2 in a concentration-dependent manner, and βig-h3-mediated adhesion and migration were more effectively inhibited by MFK902, compared with RGD or MFK00 peptides. The arthritis activity of murine CIA, measured by clinical arthritis index and incidence of arthritic paws, was significantly ameliorated after treatment with all dosages of MFK902 (1, 10, and 30 mg/kg). MFK902 ameliorated histopathologic deterioration and reduced the expression of inflammatory mediators simultaneously with improvement of clinical features. In addition, a favorable safety profile of MFK902 was demonstrated in vivo. Conclusion The present study revealed that MMP-2-cleavable peptide complex based on βig-h3 structure is a potent and safe therapeutic agent for chronic inflammatory arthritis, thus providing reliable evidence for a MMP-2-cleavable mechanism as a tissue-targeted strategy for treatment of RA.

Abstract
Salvia plebeia R. Br. has been used to treat a variety of inflammatory diseases and as an antioxidant in many countries, including Korea and China. In this study, we investigated the effects of S. plebeia extract (SPE) on inflammatory arthritis and the underlying mechanisms of action. We used a collagen-induced arthritis (CIA) mouse model. TNF-α-stimulated rheumatoid arthritis (RA) synovial fibroblasts were used to elucidate the underlying mechanisms of action. Oral administration of SPE improved the clinical arthritis score, footpad thickness, and histologic changes, as well as serum IgG1 and IgG2a levels. SPE administration inhibited Th1/Th2/Th17 phenotype CD4(+) T lymphocyte expansion in inguinal lymph node and expression of inflammatory mediators such as cytokines, MMP-1, and MMP-3 in the ankle joint tissue. SPE significantly suppressed the expression of cytokines and MMP-1 by down-regulating NF-κB, Akt, and mitogen-activated protein kinases in RA synovial fibroblasts. Taken together, these results indicate that SPE is therapeutically efficacious against chronic inflammatory arthritis, suggesting that SPE is a candidate for treating RA.

Abstract
We demonstrated that arthritis could be visualized noninvasively using hydrophobically modified glycol chitosan nanoparticles labeled with Cy5.5 (HGC-Cy5.5) and an optical imaging system. Activated macrophages expressing Mac-1 molecules effectively phagocytosed HGC-Cy5.5, which formed spherical nanoparticles under physiologic conditions. We estimated the applicability of HGC-Cy5.5 to quantitative analysis of arthritis development and progression. Near-infrared fluorescence images, captured after HGC-Cy5.5 injection in mice with collagen-induced arthritis, showed stronger fluorescence intensity in the active arthritis group than in the nonarthritis group. According to the progression of arthritis in both collagen-induced arthritis and collagen antibody-induced arthritis models, total photon counts (TPCs) increased in parallel with the clinical arthritis index. Quantitative analysis of fluorescence after treatment with methotrexate showed a significant decrease in TPC in a dose-dependent manner. Histologic evaluation confirmed that the mechanism underlying selective accumulation of HGC-Cy5.5 within synovitis tissues included enhanced phagocytosis of the probe by Mac-1-expressing macrophages as well as enhanced permeability through leaky vessels. These results suggest that optical imaging of arthritis using HGC-Cy5.5 can provide an objective measurement of disease activity and, at the same time, therapeutic responses in rheumatoid arthritis.

Abstract
The chemokine receptor [C-C chemokine receptor 5 (CCR5)] is expressed on diverse immune effecter cells and has been implicated in the pathogenesis of rheumatoid arthritis (RA). This study sought to determine whether single-nucleotide polymorphisms (SNPs) in the CCR5 gene and their haplotypes were associated with susceptibility to and severity of RA. Three hundred fifty-seven patients with RA and 383 healthy unrelated controls were recruited. Using a pyrosequencing assay, we examined four polymorphisms -1118 CTAT(ins) (/del) (rs10577983), 303 A>G (rs1799987), 927 C>T (rs1800024), and 4838 G>T (rs1800874) of the CCR5 gene, which were distributed over the promoter region as well as the 5' and 3' untranslated regions. No significant difference in the genotype, allele, and haplotype frequencies of the four selected SNPs was observed between RA patients and controls. CCR5 polymorphisms of -1118 CTAT(del) (P = 0.012; corrected P = 0.048) and 303 A>G (P = 0.012; corrected P = 0.048) showed a significant association with radiographic severity in a recessive model, and, as a result of multivariate logistic regression analysis, were found to be an independent predictor of radiographic severity. When we separated the erosion score from the total Sharp score, the statistical significance of CCR5 polymorphisms showed an increase; -1118 CTAT(ins) (/del) (P = 0.007; corrected P = 0.028) and 303 A>G (P = 0.007; corrected P = 0.028). Neither SNPs nor haplotypes of the CCR5 gene showed a significant association with joint space narrowing score. These results indicate that genetic polymorphisms of CCR5 are an independent risk factor for radiographic severity denoted by modified Sharp score, particularly joint erosion in RA.

Abstract
Objective. To investigate the quantitative analysis of disease activity using the optical imaging system with hydrophobically modified glycol chitosan labeled with Cy5.5 (HGC-Cy5.5) in animal arthritis model.
Methods. Fluorescence reflectance images were captured two hours after intravenous injection of HGC-Cy5.5 nanoprobe from the paws of collagen-induced arthritis mice. Immunofluorescence staining for F4/80 and Mac-1 molecules were performed to identify the cell types phagocytosing HGC nonoprobe, both in vivo and in vitro.
Results. In raw reflectance images, paws of the active arthritis group showed stronger fluorescence intensity than those of nonarthritis group. According to the progression of arthritis, total photon counts (TPC) increased until 5 weeks after the booster injection in parallel with the clinical arthritis index. The quantitative analysis of fluorescence intensity showed that the TPC had significant differences in methotrexate treated groups compared with an untreated group. Fluorescence microscopy demonstrated considerable accumulation of HGC-Cy5.5 within the synovial tissues, with the localization of the probe within the interstitial and a portion of cells expressing Mac-1 molecule. Macrophages differentiated with the stimulation of GM-CSF revealed conspicuous intracellular NIRF signal after two hours of incubation with the HGC-Cy5.5, with up-regulated expression of Mac-1 on the surface.
Conclusion. The present results indicate that the quantitative analysis of joint inflammation using HGC-Cy5.5 nanoprobe can provide an objective measurement of disease activity in RA.

Abstract
OBJECTIVE To delineate the expression of transforming growth factor beta-inducible gene h3 (betaIG-H3) in rheumatoid synovitis and to determine the regulatory role of betaIG-H3 in the adhesion and migration of fibroblast-like synoviocytes (FLS). METHODS Synovial tissue was obtained from patients with rheumatoid arthritis (RA) during joint replacement surgery, and FLS were isolated using enzymatic treatment. Immunohistochemical staining was performed to show the expression of betaIG-H3 within rheumatoid synovium. Synthesis of betaIG-H3 from FLS was determined by semiquantitative reverse transcription-polymerase chain reaction, Western blot analysis, and enzyme-linked immunosorbent assay. Cell adhesion and migration assays were performed using the YH18 peptide in the fourth fas-1 domain of betaIG-H3 and function-blocking antibodies to integrins. RESULTS Expression of betaIG-H3 was up-regulated in RA synovial tissue compared with synovial tissue from patients with osteoarthritis. FLS isolated from RA synovial tissue constitutively produced betaIG-H3, which was up-regulated by transforming growth factor beta1, interleukin-1beta, and tumor necrosis factor alpha. Although FLS expressed a variety of integrins, betaIG-H3 mediated adhesion and migration of FLS through interaction with alpha v beta3 integrin. Cytokines failed to affect the betaIG-H3-mediated adhesion. However, migration of FLS guided by betaIG-H3 was enhanced by interferon-gamma and platelet-derived growth factor type BB. The YH18 peptide in the fourth fas-1 domain of betaIG-H3 inhibited adhesion and migration in a dose-dependent manner. CONCLUSION The results suggest that betaIG-H3, which is abundantly expressed in RA synovial tissue, plays a regulatory role in chronic destructive inflammation through the modulation of the adhesion and migration of FLS. This finding indicates the relevance of betaIG-H3 and alpha v beta3 integrin-interacting motifs as potential therapeutic targets in this disease.

Abstract
OBJECTIVES To investigate the role of polymorphisms of the vascular endothelial growth factor (VEGF) gene in susceptibility to ankylosing spondylitis (AS), and their relationship to clinical features and radiographic severity. METHODS This study included 157 patients with AS and 140 healthy unrelated controls. Polymorphisms of the VEGF gene were analysed by the polymerase chain reaction (PCR)-restriction fragment length polymorphism assay and amplification refractory mutation system-PCR. Haplotypes were reconstructed using the Bayesian algorithm. Radiographic severity was assessed by the Bath Ankylosing Spondylitis Radiological Index (BASRI). RESULTS The genotype frequencies of the polymorphisms were in Hardy-Weinberg equilibrium. The distributions of genotypes and alleles did not differ between AS patients and controls. Among the six haplotypes reconstructed based on the tight linkage disequilibrium at positions -2578, -1154 and -634 (pairwise linkage disequilibrium coefficient, r = 0.361-0.706), no haplotype was associated with susceptibility to AS. Clinical features were analysed for the four haplotypes (CGC, CGG, AAG, AGG) which were prevalent. In carriers of the AGG haplotype, the frequency of cervical spine involvement was significantly higher (P = 0.002, P(corr) = 0.036) and that of patients showing a BASRI score >6 was also higher (P = 0.025, P(corr) = 0.45). CONCLUSIONS This study demonstrates that polymorphisms of the VEGF gene may contribute to disease severity in AS.

Abstract
OBJECTIVES To investigate polymorphisms of the VEGF gene in patients with rheumatoid arthritis (RA), their relationship to clinical features and the radiographic progression of joint disease. METHODS One hundred and forty patients with RA and 149 healthy unrelated controls were recruited. We examined four polymorphisms of the VEGF gene which are reported to be associated with production of vascular endothelial growth factor (VEGF), using polymerase chain reaction (PCR) restriction fragment length polymorphism assay and amplification refractory mutation system (ARMS) PCR. Haplotypes were predicted by Bayesian algorithm using the Phase program. RESULTS All four polymorphisms were in Hardy-Weinberg equilibrium in both patients and controls. The frequency of the 936 T allele, which has been associated with lower production of VEGF, was significantly increased in RA patients compared with controls (22.7 vs 13.4%, P = 0.002). The frequencies of two haplotypes (CGCT and AAGT) which were predicted using the Phase program were significantly increased in RA patients compared with controls [33 vs 14%, odds ratio (OR) 2.636, 95% confidence interval (CI) 1.38-5.04 for CGCT; 17 vs 6%, OR 3.08, 95% CI 1.20-7.92 for AAGT]. The carriers of the susceptible haplotypes in RA patients had a younger age at disease onset but did not show a difference in the progression rate of radiographic joint destruction. CONCLUSIONS Our data suggest that the VEGF gene may play a role in the development of RA
