3-D Vaccines: New Weapon Against Cancer

By    |   Tuesday, 09 December 2014 04:36 PM

Cancer is deadly because it is able to evade attack from the body's immune system, which allows tumors to flourish and spread. Now scientists are enlisting 3-D technology in hopes of creating a vaccine that could boost the immune system, enabling them to fight and even prevent the disease.
 
Researchers at the Wyss Institute for Biologically Inspired Engineering at Harvard University and Harvard's School of Engineering and Applied Sciences devised the technique.

It involves injecting programmable biomaterial, which would spontaneously assemble inside the body into a 3-D structure that could fight and even help prevent cancer.
 
So far, the researchers have tested the 3-D vaccine only in mice, but it has proven highly effective. An experiment showed that the injectable 3-D scaffold recruited and attracted millions of dendritic cells (which are messenger cells for the immune system) in a host mouse, before dispersing the cells to the lymph nodes and triggering a powerful immune response.
 
"Injectable immunotherapies that use programmable biomaterials as a powerful vehicle to deliver targeted treatment and preventative care could help fight a whole range of deadly infections, including common worldwide killers like HIV and Ebola, as well as cancer," said Dr. Donald Ingber, the founding director of the Wyss Institute.
