Proved: therapeutic vaccine against cancer works in 100% of cases
Staff Moffitt Cancer Center have successfully tested on rodents synthetic vaccine against cervical cancer caused by the human papilloma virus, said Medical Express. According to Esteban Tselisa, the virus triggers the development of 99% of cases of cervical cancer each year claiming the lives of more than 250,000 people worldwide.
Also human papilloma virus can cause cancer of the head, neck and genitals. At the moment, widespread prophylactic vaccines to prevent infection with the virus, which, however, do not treat the cancer itself.
Solve this problem was created by the program TriVax-HPV. According to the proposed strategy in the body to create large quantities of cytotoxic T-cells, which will try to discover proteins HPV16-E6 and E7, produced in tumors. Vaccine to target these proteins can create initiate an immune response without the risk of autoimmune disorders.
In testing the vaccine on tumors caused by HPV16, it was established that the vaccine TriVax, containing a small synthetic peptide protein E7, made it possible to remove the tumor in 100% of cases. But in the control group tumor continued to grow, and rather quickly. Now it remains to check whether the same way a vaccine works in the human body.
