Nanolipogel delivers multiple cancer treatments to boost survival rates

NSF - 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.

This illustration depicts a nanolipogel, developed at Yale University with NSF support, administering its immunotherapy cargo. The light-blue spheres within the blood vessels and the cutaway sphere in the foreground, are the nanolipogels (NLGs). As the NLGs break down, they release IL-2 (the green specks), which helps recruit and activate a body's immune response (the purple, sphere-like cells). The tiny, bright blue spheres are the additional treatment, a cancer drug that inhibits TGF-beta (one of the cancer's defense chemicals). Credit: Nicolle Rager Fuller, NSF
