Researchers at the University of Pennsylvania have pinpointed a protein that triggers hair loss, BBC reported.
據(jù)英國廣播公司報(bào)道，賓夕法尼亞大學(xué)的研究人員找到了一種引起脫發(fā)的蛋白質(zhì)。
They found levels of a key protein called prostaglandin D synthase are elevated in the cells of hair follicles located within bald patches on the scalp, but not in hairy areas, and transplanted human hairs stopped growing when given the protein.
他們發(fā)現(xiàn)，在沒長頭發(fā)的區(qū)域，毛囊中含有較多的前列腺素D合酶，而在有頭發(fā)的地方，毛囊中則沒有該物質(zhì)，且一旦有了該蛋白質(zhì)，移植的人的頭發(fā)就停止生長。
The halting of hair growth is triggered when the protein binds to a receptor on the cells of hair follicles, said Prof. George Cotsarelis, who led the research.
研究帶頭人喬治•考茨里利斯教授認(rèn)為，該蛋白質(zhì)附著在毛囊細(xì)胞中的某個(gè)受體上后就會(huì)使頭發(fā)停止生長。
The professor also said that there is potential for developing a treatment that can be applied to the scalp to prevent baldness and possibly help hair re-grow.
考茨里利斯教授說，現(xiàn)在很有希望研制出一種可以用在頭皮上的藥物，它不僅可防止禿頭，還可能幫助頭發(fā)重新生長。
