據(jù)新華社電 美國航天局一項雙胞胎對比研究顯示,長期太空生活有可能會讓宇航員的免疫系統(tǒng)處于高度警戒狀態(tài),并改變他們一些基因的活躍程度。2015 年至 2016 年,美國宇航員斯科特 · 凱利在國際空間站上連續(xù)生活 340 天,而他的雙胞胎兄弟馬克 · 凱利在地面生活。美國航天局利用兄弟倆開展了獨(dú)特的對比研究,希望進(jìn)一步了解長期太空生活對人體健康的影響。在近日召開的美國科學(xué)促進(jìn)會年會上,研究人員公布了一項初步發(fā)現(xiàn):接近一年的太空生活讓斯科特的免疫系統(tǒng)變得超級活躍。免疫系統(tǒng)是人體防衛(wèi)病原體入侵的重要防線。參與研究的美國韋爾 · 康奈爾醫(yī)學(xué)院遺傳學(xué)者克里斯托弗 · 梅森說,斯科特身體對太空環(huán)境的反應(yīng),就好像他體內(nèi)多了一個陌生器官一般。梅森表示,斯科特體內(nèi)一些與免疫系統(tǒng)有關(guān)的基因變得超級活躍。雖然基因本身沒有改變,但其表達(dá)卻有所不同,即基因的開與關(guān)、產(chǎn)生蛋白質(zhì)的多少發(fā)生了變化。他還發(fā)現(xiàn),斯科特血液中一種顯示免疫系統(tǒng)增強(qiáng)的標(biāo)志物增多,而一種與早期病毒防御相關(guān)的細(xì)胞類型卻有所減少。研究人員表示,目前尚無法確定這些變化會對人體造成什么影響。但基因活動在太空中發(fā)生變化并不奇怪,因為人體會對環(huán)境的改變作出反應(yīng)。斯科特回到地球后不久,身體各項指標(biāo)就大體恢復(fù)正常。研究人員認(rèn)為,雙胞胎對比研究尚未發(fā)現(xiàn)新的重要警示信息,這對長期太空飛行來說總體上是一個令人鼓舞的消息。此...

2019年6月24日訊 /生物谷BIOON /——普林斯頓大學(xué)的Bonnie Bassler及其同事于近日在《PLOS Pathogens》上發(fā)表的一項研究表明,他們已經(jīng)開發(fā)出一種新的突變型受體,這種受體被一種細(xì)菌病原體用來進(jìn)行一種稱為群體感應(yīng)的化學(xué)交流過程。正如作者所指出的,突變受體可作為識別抑制群體感應(yīng)的治療化合物,以滿足迫切的醫(yī)療需求。圖片來源:McCready AR, et al. (2019)人類病原體綠膿桿菌利用群體感應(yīng)來協(xié)調(diào)群體行為,包括生物膜的形成和促感染分子的產(chǎn)生。群體感應(yīng)是綠膿桿菌成為病原體的關(guān)鍵,它依賴于細(xì)胞外信號分子的產(chǎn)生、釋放和檢測。自誘導(dǎo)因子與受體蛋白結(jié)合,共同激活群體感應(yīng)基因的轉(zhuǎn)錄。在這項新研究中,Bassler和他的同事發(fā)現(xiàn)、純化并鑒定了綠膿桿菌RhlR群體感應(yīng)受體的突變版本,他們稱之為RhlR*。值得注意的是,RhlR*不需要它的合作自動誘導(dǎo)器來工作。攜帶RhlR*的綠膿桿菌能正確形成生物膜,產(chǎn)生毒力因子,感染蛔蟲。由于RhlR*不依賴于一種自動誘導(dǎo)劑來發(fā)揮作用,以前無法用RhlR進(jìn)行的生化和遺傳分析可以用RhlR*進(jìn)行。這一發(fā)現(xiàn)為綠膿桿菌群體感應(yīng)元件的工作機(jī)制提供了新的見解,其中最引人注目的是PqsE酶,它與RhlR一起控制毒力因子的產(chǎn)生。作者認(rèn)為,RhlR*是了解綠膿桿菌細(xì)胞間通訊和毒性的一個特別有價值的工具,而綠膿桿菌是一種具有高度臨床相關(guān)性...
