【摘要】:目的通過檢測單核細(xì)胞和巨噬細(xì)胞上IL-18R的表達(dá),探討IL-18在鼠顳下頜關(guān)節(jié)炎中的可能作用。方法SPF級BALB/c雄性小鼠30只,隨機(jī)分為A、B、C、D、E組,每組六只。每組給予不同處理:A組僅注射0.9%氯化鈉注射液、B組注射Ⅱ型膠原酶和NS;C組注射Ⅱ型膠原酶和IL-18;D組注射Ⅱ型膠原酶和IL-18BP;E組注射Ⅱ型膠原酶和IL-18BP和IL-18。B、C、D、E組分別在第1天和第21天時注射Ⅱ型膠原酶(2 g/ml)100μl;C、D、E組每次注射100μl IL-18/IL-18BP(10 ng/ml),每三天注射一次。第25天,采集各組小鼠外周血、組織灌洗液。采用流式細(xì)胞術(shù)檢測單核細(xì)胞和巨噬細(xì)胞中IL-18受體陽性表達(dá)變化,酶聯(lián)免疫吸附實(shí)驗(yàn)法檢測血漿和關(guān)節(jié)組織灌洗液上清液中炎癥因子TNF-α、IL-1β水平。初步探究在單核細(xì)胞和巨噬細(xì)胞中IL-18在顳下頜關(guān)節(jié)炎發(fā)病機(jī)制中起到的作用。結(jié)果1.流式細(xì)胞術(shù)中B、C、D、E組小鼠外周血中單核細(xì)胞和顳下頜灌洗液中巨噬細(xì)胞上IL-18R的陽性表達(dá)顯著高于A組(p㩳0.001);單核細(xì)胞和巨噬細(xì)胞上IL-18R的表達(dá)C組明顯高于B、D、E組(p㩳0.001)。2.酶聯(lián)免疫吸附實(shí)驗(yàn)中B、C、D、E組小鼠血漿和顳下頜關(guān)節(jié)灌洗液上清中炎癥因子TNF-α和IL-1β的水平均高于A組(p㩳0.001);C組中炎癥因子TNF-α和IL-1β的水平明顯高于B、D、E組(p㩳0.001)。結(jié)論鼠顳下頜關(guān)節(jié)炎模型中單核細(xì)胞和巨噬細(xì)胞上IL-18R的表達(dá)升高,IL-18可誘導(dǎo)IL-18R表達(dá)進(jìn)一步升高,提示IL-18可能參與顳下頜關(guān)節(jié)炎發(fā)病。IL-18BP可抑制IL-18誘導(dǎo)的IL-18R的表達(dá)和炎癥因子的釋放,提示IL-18可能是治療顳下頜關(guān)節(jié)炎的潛在靶點(diǎn)。
[Abstract]:Objective to investigate the possible role of IL-18 in temporomandibular arthritis (TMJ) by detecting the expression of IL-18R in monocytes and macrophages. Methods Thirty BALB/c male mice of SPF grade were randomly divided into two groups, six in each group. Each group was treated differently: group A was given 0.9% sodium chloride injection, group B was injected with type 鈪,
