最近研究表明環(huán)境因素,尤其是黏膜微生物菌群及其毒素,在自身免疫性疾?。ㄈ珙?lèi)風(fēng)濕性關(guān)節(jié)炎、炎癥性腸病、系統(tǒng)性紅斑狼瘡(SLE)和其他慢性疾?。┑陌l(fā)生中扮演著重要的角色。?壓力、手術(shù)以及輕度胃腸道功能紊亂引起的腸道黏膜免疫屏障損傷,會(huì)導(dǎo)致黏膜通透性增加,進(jìn)而導(dǎo)致細(xì)菌及其毒素過(guò)度移位進(jìn)入人體,從而引起炎癥。黏膜細(xì)菌在自身免疫性疾病病理?學(xué)中的重要性已經(jīng)開(kāi)始通過(guò)許多動(dòng)物研究闡明,
??
如:??
●. 在人類(lèi)強(qiáng)直性脊柱炎模型中,無(wú)菌小鼠不能發(fā)生自發(fā)性強(qiáng)直性肌腱病。??
●. 口服大腸桿菌脂多糖會(huì)通過(guò)長(zhǎng)期激活免疫系統(tǒng)來(lái)誘導(dǎo)小鼠得輕度關(guān)節(jié)炎。??
●. 在膠原抗體誘導(dǎo)性關(guān)節(jié)炎的小鼠模型中,在給小鼠亞致病劑量的II型膠原自身抗體后再給小鼠注射大腸桿菌LPS,會(huì)比單獨(dú)給予膠原自身抗體引發(fā)更嚴(yán)重的關(guān)節(jié)炎。??
?
這其中尤其引人關(guān)注的是金黃色葡萄球菌產(chǎn)生的腸毒素(SEs),通過(guò)與各種動(dòng)物模型的研究,SEs與各種自身免疫相關(guān)疾病,如過(guò)敏性皮炎、食物過(guò)敏、結(jié)腸炎、關(guān)節(jié)炎和系統(tǒng)性紅斑狼瘡?(SLE)有關(guān)。SEs是強(qiáng)有力的免疫刺激劑,被稱(chēng)為“超級(jí)抗原”,因?yàn)樗鼈兡軌蛟跇?shù)突狀細(xì)胞上結(jié)合MHC II分子并刺激T細(xì)胞和其他炎性細(xì)胞的多克隆活化。此外,SEs非常穩(wěn)定,即使是通?過(guò)滅菌技術(shù)和消化蛋白酶處理后仍能保持其致病毒性。而在SEs中,葡萄球菌腸毒素A(SEA)和B(SEB)是已經(jīng)被證實(shí)的可引起腸炎的毒素。?

為了幫助研究人員進(jìn)一步闡明潛在的環(huán)境病原體在炎癥性疾病中的病理作用,Chondrex公司研發(fā)了用于檢測(cè)小鼠和人體(研發(fā)中)內(nèi)對(duì)E. coli、大腸桿菌LPS、?金黃色葡萄球菌SEA和SEB的抗體水平的ELISA試劑盒。?
