An experimental "Trojan-horse" cancer (рак)therapy has completely eliminated(устраненный)prostate cancer in experiments on mice, according to UK researchers(исследователи).
The team hid cancer killing viruses inside the immune system in order to sneak them into a tumour.(опухоль)
Once inside, a study in the journal Cancer Research showed, tens of thousands of viruses were released to kill the cancerous cells.
Experts labelled(обозначенный) the study "exciting," but human tests are still needed.
Using viruses to destroy rapidly growing tumours is an emerging field in cancer therapy, however one of the challenges is getting the viruses deep inside the tumour where they can do the damage.
"There's a problem with getting enough virus into the tumour," Prof Claire Lewis from the University of Sheffield told the BBC. Harnessing the body's own immune system to deliver(доставлять)a deadly virus to tumours is an exciting approach.”(подход)

She leads a team which uses white blood cells as 'Trojan horses' to deliver the viral punch. 'Surfing'
After chemotherapy or radiotherapy is used to treat cancer, there is damage to the tissue(ткань). This causes a surge in white blood cells, which swamp(болото) the area to help repair(ремонт) the damage.
"We're surfing that wave to get as many white blood cells to deliver tumour-busting viruses into the heart of a tumour," said Prof Lewis.
Her team takes blood samples and extract macrophages, a part of the immune system which normally attacks foreign invaders.(захватчики). These are mixed with a virus which, just like HIV, avoids being attacked and instead becomes a passenger in the white blood cell.
In the study, the mice were injected with the white blood cells two days after a course of chemotherapy ended.
At this stage each white blood cell contained just a couple of viruses. However, once the macrophages enter the tumour the virus can replicate. After about 12 hours the white blood cells burst and eject up to 10,000 viruses each - which go on to infect, and kill, the cancerous cells.
I think it's cool that there are viruses which can kill the cancerous cells.A lot of people will be happy. -Do you like this article? -What do you know about the cancer? -What can kill the cancerous cells? -What is the name of the therapy? -Who helped people in the exeperimentals?
Nowadays there are many dangerous diseases!!!It is a fact. But people cannot find a cure for all deseases. Of course, scientists try to do it. In my opinion, they will achieve their aim. And we will be safe!!!
It's a very important topic nowadays. In my opinion, cancer is the most dangerous disease in the world. I hope that a cure for cancer will be found. Fact that scientists have found way out at least a little to improve the condition of patients is already great progress.
