山姜素對(duì)潰瘍性結(jié)腸炎腸上皮屏障作用的影響
發(fā)布時(shí)間:2021-09-19 12:03
目的:炎癥性腸。╥nflammatory bowel diseases,IBD)是一組腸道慢性非特異性炎癥性疾病,包括潰瘍性結(jié)腸炎(ulcerative colitis,UC)和克羅恩。–rohn’s disease,CD),以腸道炎癥和黏膜損傷為特點(diǎn)。近年來,IBD的發(fā)病率顯著增加,尤其是UC患者。研究表明,免疫紊亂和氧化應(yīng)激反應(yīng)是IBD發(fā)病的主要機(jī)制,近年研究發(fā)現(xiàn),腸上皮屏障功能障礙在IBD發(fā)病中亦發(fā)揮重要作用。緊密連接(tight juction,TJ)是腸上皮屏障最重要的組成部分,其表達(dá)異常能引起腸上皮屏障通透性增加,導(dǎo)致腸腔內(nèi)致病性抗原,如細(xì)菌、病毒、內(nèi)毒素等物質(zhì)進(jìn)入黏膜固有層和血液循環(huán),引發(fā)炎癥和免疫反應(yīng)。IBD的治療目標(biāo)是誘導(dǎo)并維持臨床緩解及腸道黏膜愈合。研究顯示,IBD患者腸黏膜TJ蛋白表達(dá)異?砂l(fā)生于IBD早期階段和復(fù)發(fā)之前,并促進(jìn)疾病進(jìn)展,故TJ的完整性可能對(duì)黏膜愈合發(fā)揮重要作用。TJ是由多種蛋白組成的復(fù)合體,包括跨膜蛋白、外周膜蛋白以及細(xì)胞股骨架蛋白等。其中,claudins和occludin蛋白是跨膜蛋白的主要成員,負(fù)責(zé)調(diào)控緊密連接的通透性和維持細(xì)胞極性,Z...
