, Tarek Fahmy and colleagues at Yale University report the development of a nanogel-based delivery system that targets an immunosuppressive drug (mycophenolic acid) directly to tissues associated with immune cells.
A nanogel is composed of a polymer containing pores that can be loaded with drug compounds. Fahmy and colleagues tested the mycophenolic acid-loaded nanogel in a mouse model of lupus. Mice treated with the nanogel lived longer than untreated mice or mice treated with mycophenolic acid alone. Additionally, the onset of kidney damage, a common complication of lupus, was delayed in nanogel-treated mice. These studies suggest that nanogel-based therapies may be useful in the treatment of SLE.
