RT Journal Article ID 5544e9c7743829ac A1 Harush-Frenkel, Oshrat A1 Altschuler, Yoram A1 Benita, Simon T1 Nanoparticle-Cell Interactions: Drug Delivery Implications JF Critical Reviews™ in Therapeutic Drug Carrier Systems JO CRT YR 2008 FD 2008-12-20 VO 25 IS 6 SP 485 OP 544 AB Design strategies to enhance drug delivery at specific cellular organelle by taking advantage of the endocytotic pathways are still in the early stages of development. This review provides a summary of the endocytosis machineries and pathways, as well as their involvement in nanoparticle internalization processes into either polarized epithelial cells or nonpolarized cells, in view of the marked differences in endocytic processes occurring within those cell types. The relevance of the physicochemical properties of nanoparticles upon their entry into the cells, as well as the experimental tools used to investigate the entry of nanoparticles into cells, is also addressed. The objective of this review is to present current information and achievements for a more in-depth comprehension of the internalization process and intracellular trafficking of nanoparticulate drug delivery systems within various cells types.
