Cancer research is an area of medical science that, rightfully, gets considerable attention.
It’s no wonder even artificial intelligence (AI) has gotten into the field. Researchers from the University of Michigan are not getting left behind, with a groundbreaking method that has the potential to eliminate tumours.
This new technology uses nano-sized discs, about 10 nanometres (nm) to be exact, to teach the body to kill cancer cells.
“We are basically educating the immune system with these nanodiscs so that immune cells can attack cancer cells in a personalised manner,” said James Moon from the University of Michigan.
Each of these ‘nanodiscs’ is full of neoantigens (tumor-specific mutations) that teach the immune system’s T-cells to recognise each neoantigen and kill them.
These work hand-in-hand with immune checkpoint inhibitors that boost the responses of T-cells – forming an anti-cancer system in the body that wipes out tumours and potentially keeps them from reemerging.
“The idea is that these vaccine nanodiscs will trigger the immune system to fight the existing cancer cells in a personalised manner,” Moon added. The study is published in the journal Nature Materials.
So far, the nanodiscs were successfully tested on mice and were shown to be rather promising, eliminating tumours in 10 days. These were also able to shut down identical tumours in the mice after being reinserted 70 days later.
“This suggests the immune system ‘remembered’ the cancer cells for long-term immunity,” said Rui Kuai, lead author of the study.
Of course, it’s going to be a long while before this designer vaccine rolls out for public use. The researchers still need to scale it up for tests on larger animals. It will then take even more time before it can actually be tested on human beings.
Still, the nanodiscs increase our chances of developing a cure for cancer.
Other efforts in the field include an improved laser surgery to remove tumours, a vaccine being developed by a partnership of dozens of organisations, and an effort focused on changing cancer DNA, just to name a few.
