光免疫疗法(一种叫做psoralen的光活性化合物)可以用来触发对肿瘤的免疫反应。光免疫疗法精准靶向癌细胞,减少了目前癌症治疗中外科手术、放疗、化疗在杀死癌细胞时损伤正常细胞或周围的脏器的弊端。研究人员表示,目前最大挑战是如何在体内制造光。研究人员希望通过纳米粒子的磷光,将X射线的次级治疗剂量转化为光,激活肿瘤内部的psoralen,在那里光线通常 Photo-immunotherapy (a photoactive compound called psoralen) can be used to trigger an immune response to a tumor. Photonimmunotherapy targets cancer cells accurately and reduces the drawbacks of surgery, radiotherapy and chemotherapy during the current cancer treatment, which damages normal cells or surrounding organs when killing cancer cells. Researchers say the biggest challenge right now is how to make light in the body. Researchers hope that through the phosphorescence of nanoparticles, the secondary therapeutic dose of X-rays is converted into light, activating psoralen inside the tumor, where the light is usually
