普遍的癌症疫苗人体试验靠拢很快开始

In what could be a groundbreaking achievement, researchers report the results of the first tests of a universal cancer vaccine。

Researchers have reportedly persuaded the body’;s cells to attack and destroy cancer cells, and cancer cells only。 The results on mice and preliminary results on humans indicate that this technique could be used for tumors everywhere in the body, no matter what the type of cancer is。

Unlike the vaccines we’;re familiar with, this one would work a little bit differently。 It would be used on people who already have cancer, as opposed to people who are at risk of cancer。 It works by basically shooting pieces of RNA from patients’; cancer cells at the body’;s own immune system, metaphorically showing it the enemy and convincing it to fight against the cancer。

“;[Such] vaccines are fast and inexpensive to produce, and virtually any tumour antigen can be encoded by RNA,”; the team, led by researchers at Johannes Gutenberg University of Mainz in Germany, reports in Nature。 “;Thus, the nanoparticulate RNA immunotherapy approach introduced here may be regarded as a universally applicable novel vaccine class for cancer immunotherapy。”;

Immunotherapy in itself isn’;t a new concept。 Using the body’;s immune system to beat cancer has been used with success for years in cancer treatment, but this time it’;s different。 Techniques used until now relied on genetically engineering cancer-targeting immune cells in the lab, and then injecting them back into a patient。 The whole process is laborious and expensive。

Meanwhile, this new approach is less invasive, cheaper and can target more times of cancers。 It can be tweaked depending on the patient’;s problems, which is a significant advantage。
