Protein‐Based Nanomedicine Platforms for Drug Delivery

Abstract: Protein-based nanomedicine platforms for drug delivery comprise naturally self-assembled protein subunits of the same protein or a combination of proteins making up a complete system. They are ideal for drug-delivery platforms due to their biocompatibility and biodegradability coupled with low toxicity. A variety of proteins have been used and characterized for drug-delivery systems, including the ferritin/apoferritin protein cage, plant-derived viral capsids, the small Heat shock protein (sHsp) cage, albumin,… Show more

“…Moreover, proteins possess inherent complex structures which show tunable charges in different pH environments and also have hydrophobic sections capable of hydrophobic interactions. Thus, proteins show flexible adsorption to various substrates and, hence, the potential to serve as carriers of proteins, cells, drugs and growth factors [4,5]. Among the various types of biomaterials being developed, electrospun materials composed of ultra fine fibers are preferred for medical applications.…”

“…[ 1,6 ] Human ferritin is an ideal drug delivery carrier due to the nanoscale structure, and biocompatible, biodegradable, stable, nontoxic properties. [ 2,7,8 ] Ferritin consists of an apoferritin (AFt) protein cage and an iron core, and prevents accumulation of toxic levels of free iron in cells. AFt is composed of 24 subunits arranged into a 12 nm diameter cage with an internal 8 nm cavity.…”

“…Among the 14 channels, eight are hydrophilic and six are hydrophobic. [ 6,7,9 ] Also, the AFt cage can disassemble into subunits at low pH (<pH 4.0) allowing release of cargo, and reassemble at higher pH (>pH 5.0). [ 5 ] Ferritin circulates and binds to a variety of cell types, however, specifi c binding to cells has been seen only for H-ferritins.…”

“…The spherical cage in apoferritin can be used for the encapsulation of fluorescent dyes [77], drugs [78][79][80][81][82][83][84][85], magnetic resonance imaging contrast agents [86,87], genes [88] or other compounds [89]. Due to the self-assembly activity of apoferritin and its response to the surrounding environment, it has several advantages for use as a nanocarrier.…”
