Toda semana, vou colocar aqui no blog uma notícia interessante em inglês. O objetivo é deixar quem já sabe inglês mais informado e ajudar a treinar quem já está fazendo o curso. Já falei aqui da importância de saber o inglês. Então não perca tempo! Comece o quanto antes. Confira a notícia dessa semana!

Cancers are notorious for secreting chemicals that confuse the immune system and thwart biological defenses. To counter that effect, some cancer treatments try to neutralize the cancer's chemical arsenal and boost a patient's immune response — though attempts to do both at the same time are rarely successful.

Now, researchers have developed a novel system to simultaneously deliver a sustained dose of both an immune-system booster and a chemical to counter the cancer's secretions, resulting in a powerful therapy that, in mice, delayed tumor growth, sent tumors into remission and dramatically increased survival rates.

The researchers, all from Yale Univ., report their findings in Nature Materials.

The new immunotherapy incorporates well-studied drugs, but delivers them using nanolipogels (NLGs), a new drug transport technology the researchers designed. The NLGs are nanoscale, hollow, biodegradable spheres, each one capable of accommodating large quantities of chemically diverse molecules.
