膿毒癥是指因感染引起的反應(yīng)失調(diào)導(dǎo)致的危及生命的器官功能障礙,可累及多個(gè)臟器,導(dǎo)致臟器官功能損害或衰竭。膿毒癥是導(dǎo)致孕產(chǎn)婦死亡的主要原因之一,常常導(dǎo)致新生兒發(fā)育畸形、早產(chǎn)、以及流產(chǎn)等嚴(yán)重后果。今年2月,南方醫(yī)科大學(xué)龔神海/姜勇/肖煒教授團(tuán)隊(duì)在期刊Immunity(發(fā)表時(shí)IF=43.474)上發(fā)表了研究論文Pregnancy-induced changes to the gut microbiota drive macrophage pyroptosis and exacerbate septic inflammation,聚焦于妊娠期腸道菌群變化與膿毒癥免疫功能紊亂研究并取得進(jìn)展。欣博盛生物非常榮幸能夠作為供應(yīng)商為該項(xiàng)研究提供高品質(zhì)ELISA試劑盒,為生物醫(yī)學(xué)領(lǐng)域的科研貢獻(xiàn)一份力量。

研究詳情
有臨床證據(jù)表明懷孕期間發(fā)生的生理和免疫變化與感染和敗血癥期間疾病惡化的結(jié)果有關(guān),但這些關(guān)聯(lián)是如何加劇炎癥的發(fā)展還沒有被研究過。南方醫(yī)科大學(xué)的研究團(tuán)隊(duì)通過使用抗生素治療和糞便微生物轉(zhuǎn)移,證明膿毒癥易感性是由妊娠誘導(dǎo)的小鼠和人類腸道微生物組的變化驅(qū)動(dòng)的。
通過綜合評(píng)估對(duì)妊娠期小鼠與女性的腸道菌的多組學(xué)測(cè)試與同源重組結(jié)果,研究團(tuán)隊(duì)揭示了懷孕期間Parabacteroides merdae (P. merdae)(腸道糞副擬桿菌)數(shù)量減少將導(dǎo)致其代謝產(chǎn)物芒柄花素(Formononetin,F(xiàn)MN)減少和巨噬細(xì)胞死亡增加,從而導(dǎo)致整體免疫力下降,以至于不足以充分地清除侵入人體的病原體,加速了膿毒癥患者的死亡。
從分子機(jī)制上來看,F(xiàn)MN通過抑制負(fù)向調(diào)控蛋白受體巨噬細(xì)胞內(nèi)異質(zhì)核糖核蛋白UL2(hnRNPUL2)向細(xì)胞核的易位,隨后與NLRP3啟動(dòng)子結(jié)合,抑制巨噬細(xì)胞的焦亡。
用FMN治療或借助腺病毒技術(shù)敲除小鼠的hnRNPUL2,發(fā)現(xiàn)能夠保護(hù)膿毒癥小鼠的多器官衰竭并提高生存概率。P. merdae和FMN的腸道豐度與膿毒癥患者的進(jìn)展呈負(fù)相關(guān)。
本項(xiàng)研究成果揭示了微生物免疫軸在妊娠膿毒癥宿主中被破壞,突出了FMN-hnRNPUL2-NLRP3這一菌群-免疫互作軸在膿毒癥的治療期間具備的重要生物學(xué)意義,為研究妊娠期膿毒癥的治療方案提供有前景的策略和潛力。

小鼠白介素相關(guān)產(chǎn)品推薦
白細(xì)胞介素(interleukins, ILs),簡稱白介素,最初是指由白細(xì)胞產(chǎn)生并在白細(xì)胞之間起調(diào)節(jié)作用的細(xì)胞因子,均為小分子多肽或糖蛋白類物質(zhì)。通過評(píng)估白介素在機(jī)體內(nèi)的變化水平指標(biāo),有助于更深入地了解疾病的發(fā)生與發(fā)展。欣博盛生物可提供多種小鼠白介素相關(guān)ELISA試劑盒產(chǎn)品,方便您的科研探索!
