Nanolipogel (IMAGE) U.S. National Science Foundation Caption 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).
