New corona artificially produced antibodies to prevent infection Kitasato University etc. May 7 16:54
Research groups such as Kitasato University have announced that they have artificially created antibodies that block the new coronavirus from binding to cells and prevent infection. It has potential applications in the development of new therapeutic agents.
When infected with a virus, several kinds of proteins called "antibodies" are produced in the body. Of these, "neutralizing antibody" binds to the virus and thus prevents the virus from binding to the surface of human cells. , Is supposed to prevent infection.
A research group of Professor Kazuhiko Katayama and others at Kitasato University analyzed the proteins on the surface of the new coronavirus and analyzed the information on the genes required for binding to the virus.
Based on this information, we artificially created neutralizing antibodies that bind to the virus.
A research group examined whether artificially produced neutralizing antibodies were effective in preventing infection, but when neutralizing antibodies were not added, most of the cells were infected by the virus and died. When the Japanese antibody was added, there was almost no infection.
The research group says that it can be applied to the development of new therapeutic agents, as well as the "antibody test" that checks whether you have been infected.
Professor Katayama said, "It is a new approach to make drugs with antibodies, but if it can be put to practical use, the options for treatment will be broadened. In the future, we would like to collaborate with pharmaceutical companies to start research and development for practical application such as animal experiments." I will.
