One of the main problems in the treatment of brain tumors is poor accessibility for both medicines (since the brain is protected by the blood-brain barrier), so for operational intervention because of the danger to vital centers.
But the method of treatment with the help of viruses, about which we already wrote, got its development and in fact can be very effective!
As writes of the Journal of Experimental Medicine, it turned out that the Zika virus is able to freely enter into the cancer cells in the human brain. The study is headed by Dr. Michael Diamond from the University of Washington in St. Louis.
A group of scientists led by Diamond several years ago drew attention to the fact that the Zika virus, in the main, attacks the stem cells of the nervous tissue. In turn, very similar in their structure to tumor cells called Glioblastoma.
In the course of further research, the hypothesis was confirmed: strains of the Zika virus successfully penetrated into the cancer cells and destroyed them.
Selectivity in the “actions” of the virus, of course, can have negative consequences for the human brain, but with the correct choice of dosage and in combination with other methods of treatment, the virus can act as a “cleaner”, finishing off cells that have remained after other methods of treatment.
On this discovery, scientists have not ended their research. Implanted tumor to laboratory mice and attempted to destroy it with the help of a virus, it was noted that the growth of Glioblastomas slowed, and the tumors themselves became more sensitive to chemotherapy.
“It is important to understand that our research is only the first step towards creating safe and effective strains of the Zika virus that could fight cancer. Now we need to conduct clinical studies to “teach” the virus not to harm the brain cells. “
