Science:治疗疾病的新手段——靶向免疫细胞代谢通路?
创作:花开 审核:szx 2018年04月16日
  • 静息状态下的免疫细胞代谢率低,通过氧化磷酸化途径供能;
  • 活化的免疫细胞修正代谢通路,不同细胞倾向于利用不同的途径供能;
  • 例如:Th与Tc细胞更多利用糖酵解供能且消耗较多谷氨酰胺,Treg细胞继续利用氧化磷酸化供能且倾向于消耗脂肪酸;
  • 富马酸二甲酯、二甲双胍等以代谢通路为靶点的药物或可用于治疗免疫疾病和肿瘤;
  • 需要警惕这类药物破坏全身防御系统或损伤其他重要细胞;
  • 有公司正在研制新药,阻断氧化磷酸化治疗溃疡性结肠炎。

免疫细胞在静息和活化时开启不同的代谢通路,其异常活化可导致自身免疫性疾病,比如克罗恩病、红斑狼疮等。目前一些公司和临床研究,正在探索以免疫细胞的代谢通路为靶点,治疗克罗恩病等自身免疫病。Science近期发表的新闻特稿,对此进行了报导,值得看看。

Abstract:收起
When immune cells are stimulated to fight pathogens, they revamp their metabolism, changing their diet and the pathways they use to break down food and provide energy. B cells, cytotoxic T cells, and helper T cells boost their use of glucose and increase their reliance on the glycolysis pathway to digest the sugar. Regulatory T cells mainly dine on fatty acids and generate energy through an alternative pathway, oxidative phosphorylation. Researchers are now trying to target these pathways to treat immune diseases. Clinical trials of existing drugs such as the diabetes drug metformin are already underway, and one company is also testing a novel drug that blocks oxidative phosphorylation in patients with ulcerative colitis.
