High-tech cancer vaccine is born: effect low price-cancer vaccine-IT information
Tencent science according to the United Kingdom, the independent newspaper reported, an international team of scientists has a common anticancer vaccine received a great deal of progress. Scientists took genetic RNA coding for cancer and turn them into tiny fat particles in the, and inject it into three vessels in patients with advanced cancer.
The patient's immune system responded after injections of the vaccine, produced a killer--T to attack cancer cells. The vaccine against the continuous growth of tumors in mice has a positive effect. Researchers wrote in the paper: "this vaccine makes fast and cheap, in fact any tumor antigens are able to encode RNA. RNA nanoparticles immunotherapy can be regarded as a new and General cancer immunotherapy. ”
Papers said three patients were injected with low doses of the vaccine, and the aim of the experiment is not to test the vaccine's efficacy. Although the patient's immune system appears to have responded, but there is no evidence that were cured of their cancer. One patient after the vaccine, the researchers suspected a tumor in the lymph nodes become smaller. Another by surgical removal of the tumor patients injected with the vaccine, 7 months free. Third patient of cancer cells from the skin into the lungs, injected with a vaccine, these tumors from clinical medicine is in a stable state.
The vaccine uses RAN in different parts, it can activate dendritic cells to select the target of the immune system to attack, the body's immune system will react strongly. Cancer immune therapy in the medical field led to great interest in scientists. Although traditional cancer therapies for some diseases can be cured, but lung cancer, melanoma, and some head and neck cancers are incurable. The researchers said, patients can be an effective treatment method is a very significant step forward. This compared with chemotherapy side effects of the vaccine are very limited.
高科技抗癌疫苗诞生：效果明显，价格低廉 - 抗癌,疫苗 - IT资讯
腾讯科学讯据英国《独立报》报道，一个国际研究团队的科学家们已经在一种通用抗癌疫苗的研究中获得了非常大的进步。科学家们采集了癌症的遗传RNA编码，把它们放入到微小的脂肪粒子中，并且将其注入到三位癌症晚期的患者血管中。
病人的免疫系统在注射了疫苗之后做出反应，产生了一种攻击癌症的杀手——T细胞。这种疫苗也对于对抗老鼠体内不断生长的肿瘤有着积极的效果。研究人员在论文中写道：“这样疫苗的制造快速而且廉价，事实上任何肿瘤抗原都能够通过RNA进行编码。因此纳米粒子RNA免疫疗法可以被视作一种通用的全新癌症免疫疗法。”
论文中称，三位病人被注射了低剂量的疫苗，而且实验的目的并非为了测试这种疫苗的疗效。虽然病人的免疫系统似乎做出了反应，但是尚没有证据表明他们的癌症得到治愈。其中一位病人注射疫苗之后，研究人员怀疑淋巴结中的一个肿瘤变小。另一位通过手术切除了肿瘤的患者，在注射了疫苗之后，有7个月时间都没有复发。第三位病人的癌细胞已经从皮肤进入到肺中，在注射了疫苗之后，这些肿瘤从临床医学上讲处于稳定状态。
这种疫苗使用了RAN的不同部分，它能激活树突细胞来选择免疫系统所要攻击的目标，人体免疫系统随后会做出强烈反应。癌症免疫疗法目前在医学领域中引发了科学家们的巨大兴趣。虽然传统的癌症疗法对于部分疾病来说能够治愈，但是肺癌、黑素瘤和部份大脑以及颈部癌症是难以治愈的。研究人员称，能够对病人实施一种积极有效的治疗方法是非常重大的进步。这种疫苗与化学疗法相比产生的副作用极其有限。
