It is well known that Rabies virus (RV) is the causative agent of rabies, a zoonotic infectious disease. At present, there is still no effective treatment for rabies in medical treatment. The mortality rate after rabies is almost 100%. Patients usually die of respiratory or circulatory failure within 3 to 6 days. Therefore, preventive measures should be strengthened. It is reported that the number of deaths caused by rabies every year is tens of thousands. People often hear the "rabies virus" and change color. Specific function of rabies virus: neurotropic It is such a ruthless killer, but has an important ability - neurotropic (the ability to enter the nerve cells), can be used to infect the catheter of the brain tissue. As a result, scientists skillfully used the neurotropic capacity of rabies virus to transform it into a carrier for nanomedicine for brain cancer. As mentioned earlier, rabies virus is mainly transmitted through the bite of infected animals. After thousands of years of evolution, it has the ability to invade nerve cells and enter the brain from infected muscle tissue. This way it bypasses a major obstacle, the blood-brain barrier (a selective membrane that blocks most pathogens from passing through the bloodstream). Unfortunately, the blood-brain barrier also prevents the entry of cancer drugs into infected cells, limiting patient choice. To solve this problem, scientists used rabies virus surface proteins to encapsulate nanomedicine and deliver it to the brain. Take drugs with poison! The "artifact" for precise treatment of brain cancer Scholars at Sungkyunkwan University in South Korea have recently adopted a carrier-like but more subtle approach. Nano expert Yu Seok Youn embeds gold particles in nanorods and wraps rabies virus surface proteins around them. Rodlike nanoparticles are larger than the spherical surface area, can bind more proteins, increase the binding ability of surface proteins and nerve cell receptors, and thus enter the nerve cells more effectively. The nanoparticles do not carry any other drugs, and the gold particles themselves absorb the heat generated by the laser and use high temperatures to kill the surrounding tissue. To see if the new particles can effectively kill tumor cells. Youn and colleagues injected the granules into four mice with brain tumors and found that they could quickly enter the brain and enrich in the vicinity of the tumor; then they used an infrared laser to illuminate the nanoparticles and heat them to 50. Around °C, the laser can easily pass through the skin and skull without harm, and only has a thermal effect on the tissue surrounding the nanoparticles. It has been observed that this type of treatment results in a significant reduction in tumor volume. Recently, Youn et al. reported the study at Advanced Materials. In another experiment, the researchers used the same method to treat mouse tumor cells and injected granules into their flanks (sides). After 7 days, the tumors of the two mice disappeared, and the tumors of the other mice shrank to about half of the original. The results of mouse animal experiments showed that the use of rabies virus as a drug carrier for brain cancer achieved the desired effect. If it is equally effective in humans, this nanoparticle-bearing virus can directly treat tumors without damaging healthy cells, or become an "artifact" for the precise treatment of brain cancer.
