Journal ArticleDOI
Self-porating polymersomes of PEG-PLA and PEG-PCL: hydrolysis-triggered controlled release vesicles.
Fariyal Ahmed,Dennis E. Discher +1 more
TL;DR: With all compositions, in both 100 nm and giant vesicles, the average release time reflects a highly quantized process in which any given vesicle is either intact and retains its encapsulant, or is porated and slowly disintegrates.
Journal ArticleDOI
Biodegradable polymersomes loaded with both paclitaxel and doxorubicin permeate and shrink tumors, inducing apoptosis in proportion to accumulated drug
Fariyal Ahmed,Refika I. Pakunlu,Aaron K. Brannan,Frank S. Bates,Tamara Minko,Dennis E. Discher +5 more
TL;DR: The polymersomes cause two-fold higher cell death in tumors than free drug and show quantitatively similar increases in maximum tolerated dose and drug accumulation within the tumors-suggesting promise for multi-drug delivery.
Journal ArticleDOI
Cell responses to the mechanochemical microenvironment--implications for regenerative medicine and drug delivery.
TL;DR: The initial findings for multipotent stem cells and also the elasticity-coupled effects of drugs on cancer cells and smooth muscle cells are summarized and the differential effects not only lend insight into mechano-sensing of the substrate by cells, but also have important implications for regeneration and molecular therapies.
Journal ArticleDOI
Emerging Applications of Polymersomes in Delivery: from Molecular Dynamics to Shrinkage of Tumors.
Dennis E. Discher,Vanessa Ortiz,Goundla Srinivas,Michael L. Klein,Younghoon Kim,David A. Christian,Shenshen Cai,Peter J. Photos,Fariyal Ahmed +8 more
TL;DR: Comparisons of polymersomes with viral capsids are shown to encompass and inspire many aspects of current designs, and polymersome loading, in vivo stealthiness, degradation-based disassembly for controlled release, and even tumor-shrinkage in vivo are reviewed.
Journal ArticleDOI
Shrinkage of a rapidly growing tumor by drug-loaded polymersomes: pH-triggered release through copolymer degradation.
Fariyal Ahmed,Refika I. Pakunlu,Goundla Srinivas,Aaron K. Brannan,Frank S. Bates,Michael L. Klein,Tamara Minko,Dennis E. Discher +7 more
TL;DR: Load, delivery, and cytosolic uptake of drug mixtures from degradable polymersomes are shown to exploit both the thick membrane of these block copolymer vesicles and their aqueous lumen as well as pH-triggered release within endolysosomes to disrupt lipid membranes and thereby enhance drug activity.
