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.

Background: Collagen-induced arthritis (CIA) in mice is animal model of autoimmune disease known as rheumatic arthritis in human. We investigated CII-specific CD4+ T cell receptor usage in CIA mice. Methods: In CIA model, draining lymph node (dLN) CD4+ T cells and splenocytes at $3^{rd},\;5^{th},\;8^{th}$ week, we investigated CII-specific T cell proliferation, production of IL-17, IFN-${\gamma}$, TNF-${\alpha}$, IL-4 and IL-10. And we also performed anti-CII IgG Ab measurements in serum level, TCRV ${\beta}$ usage and T cell clonality with RT-PCR-SSCP analysis. Also, we performed proliferative response against CII when CII-specific T cell subset is deleted. Results: CIA mice showed more increase in the serum level of anti-CII IgG than normal mice after induction of arthritis. And the level of anti-CII IgG2a in CIA mice was increased after $3^{rd}$ week after primary immunization, while anti-CII IgG1 was decreased. Draining LN CD4+ T cells have proliferated against CII stimulation at $3^{rd}$ week after $1^{st}$immunization. CD4+T cells derived from dLN of CIA mice produced proinflammatory cytokine IFN-${\gamma}$, IL-17 etc. Draining LN CD4 T cells of CIA presented higher proportion of CD4+V ${\beta}3$+subset compared to those of normal mice at $3^{rd}$ week after $1^{st}$ immunization, and they were increased in proportion by CII stimulation. Draining LN CD4+ T cells without TCRV ${\beta}3+/V{\beta}8.1/8.2+/V{\beta}$10b+cells were not responsive against CII stimulation. But, CII-reactive response of TCRV ${\beta}3-/V{\beta}8.1/8.2-/V{\beta}$10b- T cells was recovered when $V{\beta}3+$ T cells were added in culture. Conclusion: Our results indicate that CD4+$V{\beta}3+$ T cells are selectively expanded in dLN of CIA mice, and their recovery upon CII re-stimulation in vitro, as well as the production Th1-type cytokines, may play pivotal role in CIA pathogenesis.

Objective: We have evaluated UDHA into the joint for its effectiveness on immune responses to CII in the rat CIA. In an attempt to gain further insight into the mode of action of UDHA, we also investigated the effects of UDHA on the incidence and development of arthritis in rat CIA with 2 different regimens: (1) started prior to a primary immunization, (2) started on the day of a primary immunization. Methods : Male rats were immunized with an emulsion of $200\;{\mu}g/100g$ of CII and complete Freund's adjuvant (CFA). The rats were then given intraperitoneal(i.p) stimulation of Ulmus davidiana Planch herbal acupuncture(UDHA) or saline during the experiment. Lymph node cells were obtained from rats 14 days after immunization and cultured in vitro with CII. When compared with rats treated with saline as control, UDHA at doses of more than $20\;{\mu}g/100\;g$ rat once a day for 7 days inhibited the ability of inguinal lymph node cells to produce T cell cytokines interleukin-$1{\beta}$, tumor necrosis $factor-{\alpha}$ $(TNF-{\alpha})$. When rats were injected intraperitoneally with SRBC, hemaglutination titers in UD-treated and control rats did not differ significantly when low doses of UD was given to rats. However, i.p injection of UD at doses of more than $10\;{\mu}g/100\;g/day$ for 7 days slightly suppressed antibody production. Results : The present results show that treatment with UDHA can inhibit the onset and development of arthritis and the immune responses to collagen. Conclusion: Therapeutic i.p injection with UD affect the clinical course of the disease and the immune responses to CII.

Rheumatoid arthritis is an autoimmune disease involving multiple joint. In order to access the suppressive effects of JTT on rheumatoid arthritis and it's effects on immune system we investigated whether JTT could suppress the disease progression of collagen-induced arthritis. DBA/1 mice were immunized with bovine type II collagen. After a second collagen immunization, mice were treated with DW, JTT (200 or 400 mg/kg) or methotrexate (MTX, 30 mg/kg) as a positive control. Oral administration of JTT significantly suppressed the progression of CIA, which extend is comparable to that of MTX. Histological examination reveled that JTT inhibited infiltration of inflammatory cells into affected paw joint and bone erosion and cartilage destruction were greatly reduced compared with control. Total cell number of spleen, lymph node and peripheral blood were significantly reduced. The absolute number of CD19$^+$, CD3$^+$/CD69$^+$, CD4$^+$/CD25$^+$ cell in spleen from JTT treated mice were significantly decreased. The absolute number of CD19$^+$, CD3$^+$, CD3$^+$/CD69$^+$, CD4$^+$, CD4$^+$/CD25$^+$ CD8$^+$, CD49b, CD3/CD49b cells in draining lymph node were significantly increased compared with control. In peripheral blood mononuclear cells of JTT treated mice, the absolute number of CD4$^+$, CD4$^+$/CD25$^+$, CD3$^+$/CD69$^+$ cells were significantly decreased compared with control, while that of CD49b$^+$ was slightly increased. Infiltration of CD3$^+$ cells and CD11b$^+$/Gr-1$^+$ cells into paw joint was significantly reduced in JTT treated mice. The levels of pathologic cytokines including TNF-a and IL-6 in serum were significantly decreased by oral treatment with JTT The levels of IFN-g in the culture supernatant of splenocyte stimulated with CD3$^+$/CD28$^+$ or collagen were dramatically decreased, while the levels of IL-4 was increased under CD3$^+$/CD28$^+$ or collagen stimulation. Rheumatoid factors including IgG, IgM and collagen specific antibody were present much lower in the serum of JTT treated mice than control. Taken together, JTT has suppressive effects on rheumatoid arthritis by modulating immune system, and has potential to use anti-rheumatic arthritic agent in human.

Oral administration of antigen has long been considered as a promising alternative for the treatment of chronic autoimmune diseases including rheumatoid arthritis (RA), and oral application of type II collagen (CII) has been proven to improve pathogenic symptoms in RA patients without problematic side effects. To further current understandings about the immune suppression mechanisms mediated by orally administered antigens, we examined the changes in IgG subtypes, T-cell proliferative response, and proportion of interleukin (IL)-10 producing Th subsets in a time course study of collagen induced arthritis (CIA) animal models. We found that joint inflammation in CIA mouse peaked at 5 weeks after first immunization with CII, which was significantly subdued in mice pre-treated by repeated oral administration of CII. Orally tolerized mice also showed increase in their serum level of IgG1, while the level of IgG2a was decreased. T-cell proliferation upon CII stimulation was also suppressed in lymph nodes of mice given oral administration of CII compared to non-tolerized controls. When cultured in vitro in the presence of CII, T-cells isolated from orally tolerized mice presented higher proportion of $CD4^+IL-10^+$ subsets compared to non-tolerized controls. Interestingly, such increase in IL-10 producing cells were obvious first in Peyer's patch, then by 5 weeks after immunization, in mesenteric lymph node and spleen instead. This result indicates that a particular subset of T-cells with immune suppressive functions might have migrated from the original contact site with CII to inflamed joints via peripheral blood after 5 weeks post immunization.

Objectives : The objective of this study is to investigate the suppressing effect of the cervi pantotrichum cornu pharmacopuncture on the expression of iNOS mRNA and production of NO in synoviocytes from artificially arthritis-induced mice. Methods : In vitro test, synoviocytes extracted from a knee joint of a mouse were cultivated, and the herbal extract of cervi pantotrichum cornu($0.4mg/m{\ell}$, $0.6mg/m{\ell}$, $0.8mg/m{\ell}$, and $1.0mg/m{\ell}$) was added into the wells of synoviocytes to suppress the expression of iNOS mRNA and production of NO. In vivo test, each ten mice were allocated into three groups; Normal group, CIA-elicitated group(CIA), and group treated with cervi pantotrichum cornu pharmacopuncture after CIA elicitation(CCA). The extract of cervi pantotrichum cornu was injected into the acupoint of $SP_{10}$ to observe the changes of foot thickness in mice and the suppression of MIF, TNF-$\alpha$, NF-${\kappa}B$ p65, and iNOS. Results : In vitro test, the expression of iNOS mRNA and production of NO were dose-dependently decreased in the wells of synoviocytes treated with PMA. In vivo test, the suppression of MIF, TNF-$\alpha$, NF-${\kappa}B$ p65, and iNOS was clearly shown in the pieces of the synovial joint treated with the extract of cervi pantotrichum cornu. The foot thickness also decreased dose-dependently. Conclusions : It is speculated that the cervi pantotrichum cornu pharmacopuncture can be applicable to the therapy of rheumatoid arthritis by suppressing the expression of iNOS mRNA and production of NO.

Objective: The role of prostaglandin $E_2$ (PGE2) in the etiopathogenesis of immune and inflammatory diseases has become the subject of recent debate. To determine the role of PGE2 in rheumatoid arthritis (RA), we tested the effect of exogenous PGE2 on the production of cyclooxygenase-2 (COX-2) by rheumatoid synoviocytes. Methods: Fibroblast-like synoviocytes (FLS) were prepared from the synovial tissues of RA patients, and cultured in the presence of PGE2. The COX-2 mRNA and protein expression levels were determined by RT-PCR and Western blot analysis, respectively. The PGE2 receptor subtypes in the FLS were analyzed by RT-PCR. Electrophoretic mobility shift assay (EMSA) was used to measure the NF-${\kappa}B$ binding activity for COX-2 transcription. The in vivoeffect of PGE2 on the development of arthritis was also tested in collagen induced arthritis (CIA) animals. Results: PGE2 ($10^{-11}$ to $10^{-5}M$) dose-dependently inhibited the expression of COX-2 mRNA and the COX-2 protein stimulated with IL-$1{\beta}$, but not COX-1 mRNA. NS-398, a selective COX-2 inhibitor, displayed an additive effect on PGE2-induced COX-2 downregulation. The FLS predominantly expressed the PGE2 receptor (EP) 2 and EP4, which mediated the COX-2 suppression by PGE2. Treatment with anti-IL-10 monoclonal antibodies partially reversed the PGE2-induced suppression of COX-2 mRNA, suggesting that IL-10 may be involved in modulating COX-2 by PGE2. Experiments using an inducer and an inhibitor of cyclic AMP (cAMP) suggest that cAMP is the major intracellular signal that mediates the regulatory effect of PGE2 on COX-2 expression. EMSA revealed that PGE2 inhibited the binding of NF-${\kappa}B$ in the COX-2 promoter via a cAMP dependent pathway. In addition, a subcutaneous injection of PGE2 twice daily for 2 weeks significantly reduced the incidence and severity of CIA as well as the production of IgG antibodies to type II collagen. Conclusion: Our data suggest that overproduced PGE2 in the RA joints may function as an autocrine regulator of its own synthesis by inhibiting COX-2 production and may, in part, play an anti-inflammatory role in the arthritic joints.
