Plant derived edible nanoparticles as a new therapeutic approach against diseases.

In plant cells, nanoparticles containing miRNA, bioactive lipids and proteins serve as extracellular messengers to mediate cell-cell communication in a manner similar to the exosomes secreted by mammalian cells. Notably, such nanoparticles are edible. Moreover, given the proper origin and cargo, plant derived edible nanoparticles could function in interspecies communication and may serve as natural therapeutics against a variety of diseases. In addition, nanoparticles made of plant-derived lipids may be used to efficiently deliver specific drugs. Plant derived edible nanoparticles could be more easily scaled up for mass production, compared to synthetic nanoparticles. In this review, we discuss recent significant developments pertaining to plant derived edible nanoparticles and provide insight into the use of plants as a bio-renewable, sustainable, diversified platform for the production of therapeutic nanoparticles.
