The reporter learned from Suzhou Institute of nanotechnology, Chinese Academy of Sciences that the cancer diagnosis and treatment team led by researcher Zhu Yimin of the Institute has recently screened out a new peptide sequence that can be used in tumor immunotherapy This peptide provides a new tool for tumor immunotherapy In recent years, immunotherapy has become a new hot spot in anti-tumor research, and become the fourth tumor treatment after surgery, radiotherapy and chemotherapy because of its advantages of low drug resistance, long-term effect and low side effects At present, the U.S Food and Drug Administration (FDA) has approved the listing of a variety of related antibody drugs for tumor immunotherapy These antibody drugs can block the "confusion" of tumor cells to human immune T cells and stimulate the auto immune function to fight against tumor However, due to the large molecular weight, antibody can not enter into some pathological vessels and sometimes can not reach the affected area Zhu Yimin's team has been exploring new drugs and has focused on polypeptides Similar to antibodies, polypeptides are also composed of amino acids, but their molecular weight is less than 1 / 200 of that of antibodies They have significant advantages in reaching the affected area and being cheap The relevant research results have recently been published in the American Journal of cancer immune research.
