<B>Objective.</B><P>To examine the effect of interleukin 17 (IL-17) on the expression of Toll-like receptor (TLR)-2, 4, and 9 in collagen-induced arthritis (CIA) in mice.</P><B>Methods.</B><P>On Days 28 and 32 after induction of CIA in mice, phosphate-buffered saline (PBS group) or IL-17 (IL-17 group) was injected into both knee joints. On Day 35, mice were sacrificed. The severity of knee joint arthritis, synovial inflammation, and bone destruction was measured by a scoring system using macrography and histological analysis. Synovial expression of TLR-2, 4, 9, IL-17, IL-1ß, tumor necrosis factor-α (TNF-α), and IL-6 was determined by real-time PCR and immunohistochemistry. Synoviocytes of CIA mice were cultured with IL-17 and with neutralizing antibodies to cytokine, and the expression of TLR-2, 4, 9, IL-1ß, TNF-α, and IL-6 was determined by real-time RT-PCR.</P><B>Results.</B><P>In CIA mice, knee arthritis scores, synovial inflammation, bone destruction scores, and expression of synovial TLR-2, 4, and 9, IL-17, IL-1ß, TNF-α and IL-6 were higher in the IL-17 and PBS groups than in normal DBA1 mice. These variables were also significantly higher in the IL-17 group than in the PBS group. In CIA synoviocytes, IL-17 increased the expression of TLR-2, 4, and 9, and this effect was significantly alleviated by neutralizing antibodies to IL-17, IL-1ß, and IL-6.</P><B>Conclusion.</B><P>IL-17 aggravates joint inflammation and destruction, and increases the synovial expression of TLR-2, 4, and 9 by increasing IL-1ß and IL-6. These results imply that the IL-17-induced increase in expression of TLR-2, 4, and 9, and IL-1ß and IL-6 production are involved in the IL-17-induced aggravation of arthritis.</P>

Analysis of histone deacetylase inhibitor-induced responses in human periodontal ligament fibroblasts.

Kim, Tae-Il,Han, Ji-Eun,Jung, Hong-Moon,Oh, Joung-Hwan,Woo, Kyung Mi Kluwer Academic Publishers 2013 Biotechnology letters Vol.35 No.1

<P>Periodontal ligament (PDL) fibroblasts play critical roles in the regeneration of periodontal tissues damaged by periodontitis. Histone deacetylase inhibitors (HDIs) have been suggested to be potential tools in tissue engineering. The feasibility of using the HDI, sodium butyrate (NaB) for periodontal regeneration was examined by evaluating its effect on the osteogenic differentiation of human PDL fibroblasts and its modulation of the inflammatory responses to lipopolysaccharide (LPS). NaB did not cause significant cell death at 100?μM but promoted the expression of the osteoblast phenotype (Runx2, osterix, osteocalcin, and bone sialoprotein). NaB significantly inhibited the LPS-induced production of reactive oxygen species and the expression of pro-inflammatory cytokines (IL-1β and TNF-α). These results suggest that HDIs can offer a potential therapeutic agent for periodontal regeneration.</P>

To evaluate antibiotic-induced endotoxin release(AIER) and its correlation with some cytokines, we measured endotoxin level and tumor necrosis factor alpha(TNF-α) and interleukin6(IL-6) production in mononuclear cells in vitro after exposure of Pseudomonas aeruginosa to antibiotics belonging to different class with two extreme concentrations. The tested concetration of antibiotics were set up according to peak serum level. The low concetration of ceftazidirne and low concentration of imiperiem increased AIER, but high concentration of ceftazideme, high concentration of ciprofloxacin, high concentration of cefoperazone/sulbactam, high concentration of amikacin, and high concentration of meropenem reduced AIER.Interestingly, combined treatment of these antibiotics markedly reduced AIER, But the major cyotkines, TNF-α and IL-6 were not affect by type and concettration of antibiotics, combined treatment of antibiotics, and level of endotoxin released by antiboitics. In this study, we observed AIER was different according to type of antibiotics, concentration of antibiotics, and combination of antibiotics, But AIER had poor correlation with TNF-α and IL-6 in Pseudomonas aeruginosa. It suggests that cytokine release is not solely dependent to endotoxin, but more complex cascade is needed. More invesfigations, such as endotoxin induced cytokine mRNA expression, relationship with penicillin-binding proteins and endotoxin-neutralizing effect of antibiotic itself, must be performed.

Introduction: MicroRNA-155 (miR-155) is crucial for the proinflammatory activation of human myeloid cells and antigen-driven inflammatory arthritis. Since, the functional role of miR-155 in gouty arthritis has not been defined. The aim of this study was to examine the role of miR-155 in pathogenesis of gouty arthritis. Materials and methods: Samples from fourteen patients with gouty arthritis and ten healthy controls were obtained. Monosodium urate (MSU) crystals were prepared by recrystallization from uric acid. Total RNA was isolated using the miRNeasy kit (Qiagen). The miScript Reverse Transcription Kit (Qiagen) was used for cDNA preparation. MiScript primer assay (Qiagen) were used for semiquantitative determination of the expression of human miR-155. Human TNF-α and IL-1β in supernatants were measured by Luminex (Millipore, USA) according to the instructions of the manufacturer. Gout peritonitis mice (Male C57BL/6J) model used to analyze expressions of miR-155, Src homology 2-containing inositol phosphatase-1 (SHIP-1), and inflammatory cytokines. Results: The samples from gout patients proved to be highly enriched in miR-155, with levels of expression being 4-fold higher than those found in peripheral blood mononuclear cells (PBMC) from healthy controls and gout (p<0.05). miR-155 was found to be strongly induced by stimulation of MSU crystals after 24 hours and their expressions gradually decreased. Stimulating with MSU crystals for the indicated times, and the level of SHIP-1 was found to be gradually decreased in according to over-expression of miR-155. miR-155 promoted MSU-induced proinflammatory cytokine production. Commensurate with our observations in human synovial monocytes, miR-155 expression was elevated in gout mice model. SHIP-1 protein levels were markedly reduced in cells by MSU stimulated, compared to the control. MSU crystal induced peritonitis mice significantly increased the production of inflammatory cytokines, such as TNF-α and IL-1β. Conclusion: Overexpression of miR-155 in synovial fluid mononuclear cells (SFMC) led to down-regulation of SHIP-1 and an increase in the production of proinflammatory cytokines.

큰느타리버섯의 기능성 식품으로서 활용도를 높이기 위해 동결 건조된 자실체에서 분리한 조다당체 추출물이 면역세포 활성에 미치는 효과를 조사한 결과는 다음과 같다. 조다당체 추출물은 300 및 1,000 ㎍/mL 농도에서 비장세포의 증식을 유도하였으며, 이때 비장세포는 IL-6와 IFN-γ 분비를 유도하는 것으로 나타났다. 조다당체 추출물은 농도 의존적으로 B세포의 증식을 유도하였으며, 특히 100 ㎍/mL 농도 이상에서는 B세포의 증식이 현저히 증가하는 것으로 나타났다. 그리고 조다당체 추출물 1,000 ㎍/mL 농도에서 B세포가 생산하는 IgG1, IgG2a, IgG3의 분비량이 현저히 증가하였다. 또한 농도 의존적으로 대식세포주의 일산화질소 생산을 유도하였으며, 대식세포가 분비하는 IL-6, TNF-α, GM-CSF의 생산도 현저히 증가하는 것을 확인할 수 있었다. The objective of the current study was to determine the effects of the crude polysaccharide isolated from fruit body of Pleurotus eryngii on mouse splenocytes, B cells, and macrophages in vitro. The crude poly-saccharides directly induced the proliferation of spleen cells in a dose-dependent manner and increased IL-6 and IFN-γ synthesis. The crude polysaccharides also increased the proliferation of B cells in a dose-dependent manner. The production of immunoglobulin G1, G2a and IgG3 in the presence of the crude polysaccharides was increased progressively in the culture supernatant. When the crude polysaccharide were used in macrophage cell line (RAW264.7) stimulation, there were marked induction of NO synthesis in a dose-dependent manner and IL-6, TNF-γ and GM-CSF synthesis. These results suggest that the crude polysaccharide isolated from fruit body of Pleurotus eryngii seem to act as a potent immunomodulator causing augmentation of immune cell activity, and thus could be used as a biological response modifier having possible therapeutic effects against immunological disorders, without any side effects.

This study is designed to shed light on the relationship between the communication satisfaction of sports groups on collective cohesion. With this in mind, the researcher looked into the communications and collective cohesion of sports group. The researcher conducted frequency, percentage, t-test and correlation, etc. The subjects were composed of a total of 392 out of 420(the population) belonging to 34 teams participating in a nationwide volleyball game for middle and high school boys and girls. The questionnaire was supposed to be self-administered. 28 copies were excluded from the population by thinking that their response were poor. The following are the findings. First, the subjects were highly satisfied with communications. The subjects with a high standard of living, middle school students, and subjects to participate in a lot of games turned out to be highly satisfied with communication. Second, the subjects had a high degree of social cohesion and assignment-based cohesion, and girls and players with less than two-to-three-year career had a higher degree of social cohesion. Third, the survey on the correlation between the communication satisfaction of sports groups and their collective cohesion shows that the more highly satisfied they are, the higher social cohesion and collective cohesion they had.
