Study paves the way for development of novel delivery systems to suppress HIV

In a new study supported by the National Institutes of Health, researchers used exosomes, tiny nanoparticles capable of being taken up by cells, to deliver novel protein into the cells of mice infected with HIV. The protein attached to HIVs' genetic material and prevented it from replicating, resulting in reduced levels of HIV in the bone marrow, spleen, and brain.
