The United States has developed a new cancer treatment: activation of immune cells with near infrared rays August 19, 2016 Source: Bio Valley Researcher Xiao Linjiulong, a researcher at the National Institutes of Health (NIH), published a research report in the American medical journal Science Translational Medicine, which was published on the 17th of this month. It has developed an immune cell lymphocyte that activates cancer cells by near-infrared irradiation. The ball to eliminate cancer cells. It was alleged that the therapy was also effective in metastatic cancer by mouse experiments. According to the report, there are cells in the lymphocytes that prevent them from attacking themselves by mistake and exerting a blocking effect. Immunotherapy for cancer activates the lymphocytes of the body, so there is a risk of an “autoimmune response†that attacks healthy cells, but attenuating the degree of activation reduces the therapeutic effect, which is an unsolved problem. The therapy developed this time is to destroy only the blocking effect against cancer cells. Kobayashi said that "it is possible to become a potent drug to eliminate this contradiction." Kobayashi et al. used a chemical that destroys peripheral cells under the exposure of near-infrared light of a specific wavelength, and combined the substance with a molecule that is easily bound to a "regulatory T cell" that acts as a barrier to a complex. The complex was injected into a mouse transplanted with cancer cells, and only near-infrared rays were irradiated on the cancer cells. The results showed that the regulatory T cells were destroyed, the lymphocytes were activated, the cancer cells were reduced, and the survival time became longer. In an experiment in which the same cancer cells were transplanted to different sites and simulated metastatic cancer, only one site was irradiated, and the cancer cells in other sites that were not irradiated were also reduced. According to the analysis, this is because the lymphocytes in the irradiated cancer cells are activated and then enter the bloodstream to the whole body, and only the metastatic cancers with similar characteristics are recognized as the target of attack.
