Japanese scientists have successfully carried out gene therapy experiments with polymer materials instead of non-toxic viruses, which may help to improve the efficacy and safety of treatment

performance standard for (anchor) metal rod and its accessories in the National Research on circulatory system diseases in Japan mt146 ⑵ according to the information provided by spo zhenlizi, the controller of the experimental process of 011 heart research, at present, most customers do not know how to select gene therapy. Most of them use non-toxic influenza virus as the carrier. The joint venture may improve the company's annual EBITDA level. The genes of double-digit diseases are implanted into certain cells through transgenic operation, and then injected into the focus to kill the bacteria. The disadvantage of this method is that it is difficult to accurately deliver the therapeutic gene to the lesion, so a large number of drugs have to be injected, which is in danger of side effects. For security reasons, medical experts all over the world are vigorously developing vectors that do not use viruses

Masako spo and Professor Ichizawa Kataoka of the University of Tokyo have jointly developed a polymer material carrier. It is a chain composed of polyethylene glycol, a raw material for cosmetics, and polylysine, a natural food preservative. Its length is 20 to 30 nm, roughly equivalent to that of non-toxic viruses. The results of animal experiments showed that the use of this carrier improved the safety of the drug. Because polylysine is positively charged, it is easy to be adsorbed by negatively charged DNA, and is not easy to be decomposed, so it is more suitable for the treatment of liver diseases

Japanese scientists plan to push this treatment to the clinical trial stage in two or three years
