Previous studies have indicated that incidence of rheumatoid arthritis (RA) is partly related to the damage of antioxidant systems, but etiology of RA is not fully identified. This study was performed to evaluate nutrient intakes including antioxidants, health related behaviors and food habits of RA patients and controls. RA patient group (n = 68) and sex-matched healthy controls (n = 68) were joined in this study. Nutrient intake was estimated using a semiquantitative food frequency questionnaire. As mean age of RA ($52.9{\pm}13.8$ years) was significantly higher than those of controls ($48.7{\mp}5.9$ years), data were analyzed by using Student's t-test, adjusted for age. There was no significant difference between two groups in body mass index. Compared with those of controls, frequencies of drinking (p < 0.001) and coffee consumption (p < 0.05) of RA groups were lower. RA groups had lower frequencies of fruit (p < 0.01), vegetable (p < 0.05) and fatty meat (p < 0.05) consumptions and balanced diet (p < 0.01), and higher frequencies of fried dishes (p < 0.01), and salty dishes (p < 0.01), compared to controls. The most nutrient intakes including energy intake of RA were tended to be lower than those of controls. Vitamin A, ${\beta}$-carotene and vitamin C intakes were significantly lower in RA than controls (p < 0.001). Daily vitamin A, ${\beta}$-carotene and vitamin C intakes of RA were lower than those of control (vitamin A: RA $360.6{\pm}252.23{\mu}g$ RE, control $844.5{\pm}426.2{\mu}g$ RE, p < 0.001; ${\beta}$-carotene: RA $1450.9{\pm}1019.0{\mu}g$, control $3968.8{\pm}2248.21{\mu}g$, p < 0.001; vitamin C; RA $40.6{\pm}21.48mg$, control $84.7{\pm}40.29$, p < 0.001) These results suggest sufficient consumption of antioxidant nutrients may prevent and improve RA status.

Objectives : The effects of water extract of deer antler herbal-acupunture solution(DHS), prepared from the pilose antler of Cervus korea TEMMINCK var. mantchuricus Swinhoe (Nokyong), a traditional immunosuppressive and immune-activating Korean herbal- acupuncture, on collagen-induced arthritis(CIA:RA model) in mice was studied. Destruction of cartilage and bone are hallmarks of human rheumatoid arthritis, and controlling these erosive processes is the most challenging objective in the treatment of RA. Methods : We investigated the tissue protective effects of deer antler treatment using established murine collagen-induced arthritis(CIA) as a model. Potential synergy of low dosages of anti-inflammatory glucocorticosteroids and deer antler was also evaluated. Results : Treatment of established murine CIA with deer antler herbal-acupunture solution(DHS) $(10-50{\mu}g/day)$ suppressed disease activity and protected against cartilage and bone destruction. Although $10-50{\mu}g/day$ DHS had only a moderate effect on the inflammatory component of the disease activity, it strongly reduced cartilage pathology, as determined by histological examination. Serum cartilage oligomeric matrix protein(COMP) levels were significantly reduced, confirming decreased cartilage involvement. Histological analysis showed that bone destruction was prevented. DHS administration increased serum IL-1Ra levels and reduced anticollagen type II antibody levels. Treatment with low-dose $DHS(1{\mu}g/day)$ was ineffective in suppressing disease score, serum COMP or joint destruction. Synergistic suppression of both arthritis oseverity and COMP levels was noted when low-dose DHS was combined with prednisolone(0.05mg/kg/day), however, which in itself was not effective. Conclusion : DHS was shown to have the inhibiting effects against $IL-1{\alpha}-$ and $IL-1{\beta}-stimulated$ bone resorption. These results indicated that the DAS is not only highly stable and applicable to clinical uses in bone resorption, but also it will be served as a potent anti-inflammatory and anti-arthritic agents for treatment of human RA.

This study was conducted to determine whether CD4 T cell responses to citrullinated fibrinogen occur in patients with rheumatoid arthritis (RA), especially in HLA-DR4-positive subjects. Whole peripheral blood mononuclear cells (PBMCs) of RA patients and control subjects were stimulated with citrullinated fibrinogen peptides, and T-cell production of proliferation and proinflammatory cytokines, such as interferon-${\gamma}$(IFN-${\gamma}$) and interleukin-17A (IL-17A), were measured. In addition, CD4 T cells from RA patients were stimulated with the citrullinated fibrinogen peptide, $Fib-{\alpha}$ R84Cit, identified as a DRB1*0401-restricted T cell epitope in HLA-DR4 transgenic mice, and the degree of T cell activation was examined similarly. No proliferative responses to the citrullinated fibrinogen peptides were observed in whole PBMCs or CD4 T cells from RA patients. Furthermore, no increased production of IFN-${\gamma}$ or IL-17A was found in whole PBMCs or CD4 T cells stimulated with the citrullinated fibrinogen peptides, although these cells responded to recall antigen, a mixture of tetanus toxoid, purified protein derivative (PPD) from Mycobacterium tuberculosis, and Candida albicans. The results of this study indicate that anti-citrulline immunity in RA patients may be mediated by fibrinogen because there is no evidence of CD4 T cell-mediated immune responses to citrullinated fibrinogen peptides.

Rheumatoid arthritis (RA) is a chronic autoimmune disorder characterized by progressive joint deterioration; Furthermore, RA can also affect body tissues, including the skin, eyes, lungs, heart and blood vessels. The early stages of RA can be difficult to diagnose because the signs and symptoms mimic those of many other diseases. It is not known exactly what triggers the onset of RA and how to cure the disease. But recent discoveries indicate that remission of symptoms is more likely when treatment begins early with strong medications known as disease-modifying anti-rheumatic drugs (DMARDs). Tumor necrosis factor (TNF) inhibitors are typical examples of biotherapies that have been developed for RA. The substances may occur naturally in the body or may be made in the laboratory. Other biological therapies care biological response modifiers (BRMs)such as monoclonal antibodies, interferon, interleukin-2 (IL-2) and a protein binder using repeat units. These substances play significant anti-inflammatory roles. Proteins with recurrent, conserved amino acid stretches mediate interactions among proteins for essential biological functions; for example, ankyrin (ANK), Heat repeat protein (HEAT), armadillo repeat protein (ARM) and tetratricopeptide repeats (TPR). Here, we describe Leucine rich repeats (LRR) that ideally fold together to form a solenoid protein domain and is more applicable to our current study than the previously mentioned examples. Although BRMs have limitations in terms of immunogenicity and effector functions, among other factors, in the context therapeutic use and for proteomics research, We has become clear that repeat-unit-derived binding proteins will increasingly be used in biotechnology and medicine.

Rheumatoid arthritis (RA) is a chronic inflammatory autoimmune disease. characterized by leukocyte infiltration, a chronic inflammation of the joint, a pannus formation and the extensive destruction of the 3Iticular caJ1ilage and bone. Several proinflammatory cytokines such as tumor necrosis factor-${\alpa}$(TNF-${\alpa}$), interleukin-1${\beta}$ (IL-1${\beta}$) and interleukin 6 (IL-6) have been implicated in the pathological mechanisms of synovial tissue proliferation, joint destruction and programmed cell death in rheumatoid joint. In the Korean traditional medicine, Hominis placenta (HP) as an herbal solution of herb-acupuncture has been widely used to treat the inflammatory diseases including RA. In order to study the medicinal effect of HP herb-acupuncture on rheumatoid joint, an adjuvant-induced arthritis (AlA) was generated by the injection of 1.5 mg uf Mycobactelium tuberculusis. emulsified in squalene, 10 the base of the tail of Sprague-Dawley(SD) rats. After onset stage of polyarthritis, HP was daily injected to the Zusanti (ST36) acupuncture points in both of rat lags and the expression pattems of cytokines such as TNF-{\alpa}$, IL-1${\beta}$, and 1L-6 at the knee joint were analyzed using immunostaining and RT-PCR. The HP herb-acupuncture was found to be effective to alleviate the arthritic symptums in adjuvant-induced arthritic rats as regards the joint appearance and the expression profiles of inflammatory cytokines. In conclusion, therapeutic effects of HP herb-acupuncture on the rat with AlA might be related to anti inflammatory activities of the hurb-acupuncture.

The present study was carried out to examine the effects of Kami-hwal-hyeol-tang(KHHT) on the immune responses of synoviocyte cells prepared from the rheumatoid arthritis patients, and also on the collagen-mediated arthritis in mouse model. Several experiments were performed in vitro and in vivo to analyse the immunomodulatory effects of KHHT, and the major findings are summarized below: 1. KHHT did not show the cytotoxicity against mLFCs and hFLSs. 2. KHHT inhibited gene expression of IL-1β, IL-6, TNF-α, COX-2, NOS and GM-CSF in hFLSs. Furthermore, KHHT-treated hFLSs showed reduced production of pro-inflammatory cytokines such as IL-1β and IL-6 compared to the control cells. 3. KHHT treatment of hFLSs inhibited the binding activity of NF-kB and AP-1 to their consensus DNA sequences. 4. KHHT treatment(400 ㎍/㎖) of hFLSs significantly inhibited hFLSs proliferations compared to the control cells. 5. KHHT significantly reduced the production of ROS in hFLSs compared to the control cells. The present data show that KHHT plays an important role for the regulation of AP-1 and NF-kB gene expression. Also, it was found that KHHT has anti-arthritis effect. Further studies of KHHT in relation to RA therapeutics may provide important information to develop drugs to treat this disease.

In this study, we evaluated whether the oral administration of chondroitin from the cartilage of Raja kenojei is effective on the progression of rheumatoid arthritis (RA), using collagen-induced arthritic (CIA) mice. Arthritis development was delayed dose-dependently in the chondroitin-treated groups. The pre- and late-treated groups receiving 1,000 mg/kg of chondroitin had clinical scores that were reduced significantly by 56.9 (p<0.05) and 43.3% (p<0.05), respectively, compared to the vehicle-treated groups. Hematoxylin eosin staining and X-ray radiography showed that the chondroitins reduced the infiltration of inflammatory cells and prevented joint destruction of the knee and paw. Reverse transcription-polyerase chain reaction analysis revealed that chondroitin administration inhibited the expressions of tumor necrosis $factor-{\alpha}$ ($TNF-{\alpha}$), $interlukin-1{\beta}$ ($IL-1{\beta}$), and $interferon-{\gamma}$ ($IFN-{\gamma}$) in joints more than the administration of vehicle. Chondroitin treatment also decreased the production of rheumatoid factors (RF), IgG and IgM, in the serum of CIA mice. These results indicate that chrondroitin administration has a protective effect involving the inhibition of pro-inflammatory cytokine production in CIA mice.

Molecular mimicry is an attractive mechanism for triggering autoimmunity. In this review, we explore the potential role of evolutionary conserved bacterial proteins in the production of autoantibodies with focus on granulomatosis with polyangiitis (GPA) and rheumatoid arthritis (RA). Seven autoantigens characterized in GPA and RA were BLASTed against a bacterial protein database. Of the seven autoantigens, proteinase 3, type II collagen, binding immunoglobulin protein, glucose-6-phosphate isomerase, ${\alpha}$-enolase, and heterogeneous nuclear ribonuclear protein have well-conserved bacterial orthologs. Importantly, those bacterial orthologs are also found in human-associated bacteria. The wide distribution of the highly conserved stress proteins or enzymes among the members of the normal flora and common infectious microorganisms raises a new question on how cross-reactive autoantibodies are not produced during the immune response to these bacteria in most healthy people. Understanding the mechanisms that deselect auto-reactive B cell clones during the germinal center reaction to homologous foreign antigens may provide a novel strategy to treat autoimmune diseases.

Rheumatoid arthritis(RA) is a general, chronic, inflammatory and auto-immune disease and it can lead to joint edema, pain, stiffness which are caused by an inflammation in synovium covering our joints. Ulmus davidiana Planchon is a traditional herb used for the treatment on various inflammations, gastrointestinal trouble, ENT(ear, nose, and throat) disease, edema, cancer etc. and it works effectively on arthritis as well. In these study to search for the treatment efficacy of Ulmus davidiana Planchon in RA, I measure manifestation of cytokine gene in synoviocyte treated with Ulmus davidiana Planchon herbal acupuncture and in EL-4 cell, manifestation of cytokine gene cell related to T-cell. And after Ulmus davidiana Planchon herbal acupuncture treatment in Collagen induced arthritis(CIA) which has been known by a general model of RA, DBA mice, I observed foot thickness, general shape of synovium, early cytokine induce CIA and, generation and mutation of cytokine related to the control of T-cell specialization. It comes to conclusion as belows. 1. In synovium treated with Ulmus davidiana Planchon herbal acupuncture, there was the decrease in MIF mRNA does-dependently. Incase of CIA mice treated with Ulmus davidiana Planchon herbal acupuncture, there were the decrease in the damage in synovium and generation of the MIF which is related to induction of the early RA cytokine and IL-6 proinflammatory cytokine. 2. In case of EL-4 treated with Ulmus davidiana Planchon herbal acupuncture, there were decrease in the manifestation of the IL-2 mRNA, but the increase in the manifestation of the IL-4 does-dependently. 3. In the synovium of CIA mice treated with Ulmus davidiana Planchon herbal acupuncture, there were the decrease in generation of IL-2, IL-12 and CD-28, but the increase in generation of IL-4. These result suggest that Ulmus davidiana Planchon can block the process of the early RA by Inhibiting MIF activation, and mitigate Rheumatoid Arthritis by controlling Tcell specialization.
