Scientists have developed a “nanoa drug”, the youngest of 50 thousand times from the ant, and it provides chemotherapy directly to the tumors, as nanoparticles are used invisible to the human eye to transmit chemical drugs, according to the British newspaper “Daily Mail”.
Access to a new nanic drug smaller than an ant
The newspaper said, Nanotechnologies use the invisible microscopic molecules of the human eye, to provide a new immune treatment and existing chemical medicines, and researchers from the University of Pittsburgh hope to reduce treatment from some side effects associated with traditional cancer treatments, where new treatment works by stopping the production of immune protein that is done Inhibition in cancer patients and allows tumors to grow and spread.
The newspaper pointed out that the new treatment provides a super dose targeting of chemotherapy directly for cancer through a swarm of nanoparticles that stick to the tumor itself, and chemotherapy works by killing fast -growing cancer cells, but it often accidentally attacks normal cells in other places of The body, which causes severe side effects, noting that lack of identification also means that chemotherapy can leave cancer cells without targeting and eliminating them, which begin to multiply again and may lead to relapse.
The newspaper said, in a study of mice with colon and pancreas cancer, which reduced the treatment “significantly” of the size of the tumor.
Nanoa is smaller than an ant
For his part, Dr.
Song Lee, Professor of Pharmaceutical Sciences at the Faculty of Pharmacy, University of Pittsburgh, stressed that there are two innovative aspects of the study, which are the discovery of a new therapeutic goal and a very new nanoparticle holder in the selective delivery of immune therapy and chemotherapy drugs.
In the study, published in the journal Nanotechnology, the Pittsburgh team developed a new immune treatment called Sirna, which closes a proteinist called XKR8, in people with cancer, chemotherapy causes small molecules known as phosphatidil Serene oily (PS) from the inner layer of the membranes of cancer cells To the surface of the cell, PS acts as an immunity inhibitor on the surface, protects the stuck cancer cells from the immune system, works with nanos in two ways – closing XKR8 protein and then connecting chemotherapy directly to the tumor.
The newspaper said that when tested on the mice, it produced those that have given precise treatment more cancer -resistant T cells and immunosuppressive cells are less than animals that were given an imaginary medicine or chemotherapy on its own, in contrast, the mice that received chemotherapy and immune therapy showed A significant decrease in the size of the tumor compared to the mice that got only one treatment..
