Key points from article :
Scientists invented a nanoparticle that eats away from the inside out portions of plaques.
Nanoparticle has high selectivity to an immune cell type—monocytes and macrophages.
New approach works intracellularly and has been effective in stimulating macrophages.
Inside macrophages of the plaques, it delivers a drug agent that stimulates the plaque destruction.
Marketing of the nanoparticle will begin later this year.
