Researchers at MIT and Brigham and Women’s Hospital have developed
nanoparticles that can deliver antiobesity drugs directly to fat tissue.
Overweight mice treated with these nanoparticles lost 10 percent of their body
weight over 25 days, without showing any negative side effects.
来自麻省理工学院和布里格姆女子医院的研究人员表示，他们已经开发出可靶向攻击脂肪组织的纳米粒子。该粒子能让罹患肥胖症的小白鼠在25天内减重10%，且未见任何不良反应。
The drugs work by transforming white adipose tissue, which is made of
fat-storing cells, into brown adipose tissue, which burns fat. The drugs also
stimulate the growth of new blood vessels in fat tissue, which positively
reinforces the nanoparticle targeting and aids in the white-to-brown
transformation.
这种药物能促进储存脂肪的白色组织转化为燃烧脂肪的褐色组织，并且刺激脂肪组织中的血管再生，这些新生的血管同时又对组织转化起到促进作用。
These drugs, which are not FDA-approved to treat obesity, are not new, but
the research team developed a new way to deliver them so that they accumulate in
fatty tissues, helping to avoid unwanted side effects in other parts of the
body.
这些药物目前还未获得美国药监局批准治疗肥胖症，虽然肥胖症药物不是新研发的，但是科研团队近期开发了新型传输模式，使得药物在脂肪组织上积聚，从而避免对身体其他组织产生副作用。
“The advantage here is now you have a way of targeting it to a particular
area and not giving the body systemic effects. You can get the positive effects
that you’d want in terms of antiobesity but not the negative ones that sometimes
occur,” says Robert Langer, the David H. Koch Institute Professor at MIT and a
member of MIT’s Koch Institute for Integrative Cancer Research.
“它的优点在于提供了一种针对性的方式，让我们能单独处理特定组织而不对人体产生系统性影响。这项技术针对肥胖症的积极影响可想而知，我们常听到的副作用将不复存在。”
麻省理工学院戴维·考赫研究所(DavidH. Koch Institute)教授、综合癌症研究员罗伯特·兰格(Robert Langer)如是说。
More than one-third of Americans are considered to be obese, and last year
obesity overtook smoking as the top preventable cause of cancer death in the
United States, with 20 percent of the 600,000 cancer deaths attributed to
obesity.
据估计有超过三分之一的美国人受肥胖困扰，而去年肥胖症更是超越吸烟成为全美最频发的可预防的致癌原因，在600,000例癌症死亡患者中，约有20%患有不同程度的肥胖症。
Langer and Omid Farokhzad, director of the Laboratory of Nanomedicine and
Biomaterials at Brigham and Women’s Hospital, are the senior authors of the
study, which appears in the Proceedings of the National Academy of Sciences the
week of May 2. The paper’s lead authors are former MIT postdoc Yuan Xue and
former BWH postdoc Xiaoyang Xu.
该研究发刊登在了《美国国家科学院论文集》里，兰格和布里格姆女子医院纳米医学及生物材料实验室主任奥米德·法罗哈扎德(Omid
Farokhzad)是论文资深作者，论文的第一作者是前麻省理工博士后袁雪(音译，Yuan Xue)和前布里格姆女子医院博士后徐晓阳(音译，Xiaoyang
Xu)。
