研究：氧氣或有助免疫細(xì)胞抗癌需進(jìn)行人體測(cè)試

發(fā)布時(shí)間：2015-03-06 11:11:00 來(lái)源：中國(guó)新聞網(wǎng) 作者：佚名責(zé)任編輯：羅伯特

　　中新網(wǎng)3月6日電據(jù)外媒報(bào)道，近日，一項(xiàng)對(duì)老鼠進(jìn)行的爭(zhēng)議性研究顯示，體內(nèi)吸入額外氧氣可能有助免疫細(xì)胞對(duì)抗癌癥。因?yàn)槟[瘤會(huì)筑起防御工事阻擋免疫系統(tǒng)攻擊，而腫瘤內(nèi)低氧會(huì)刺激一種分子產(chǎn)生，這種分子能阻擋腫瘤斗士T細(xì)胞。

　　美國(guó)東北大學(xué)研究人員希望通過(guò)研究確定，增加腫瘤內(nèi)的氧氣是否能消除腫瘤的防御。

　　他們讓患有肺癌的老鼠吸入氧氣，而高氧組腫瘤縮小的程度較大，尤其研究人員為老鼠注射額外T細(xì)胞后，狀況更明顯。

　　不過(guò)他們警告，這項(xiàng)方法必須進(jìn)行人體測(cè)試，才能得知是否真的對(duì)人體有效。
