Targeted pH-Gated Nanoparticle Anti-TB Drug Delivery System

Marcus Horwitz and colleagues at UCLA in the U.S. will develop and test a novel drug delivery system in which nanoparticles loaded with anti-TB drugs selectively target macrophages, and release the drugs intracellularly via a pH-dependent gate, allowing delivery of high concentrations on antibiotics into the host cells for Mycobacterium tuberculosis.
