2. Rapid fabrication of precise high-throughput filters from membrane protein nanosheets

Abstract

Biological membranes are ideal for separations as they provide high permeability while maintaining high solute selectivity due to the presence of specialized membrane protein (MP) channels. However, successful integration of MPs into manufactured membranes has remained a significant challenge. Here, we demonstrate a two-hour organic solvent method to develop 2D crystals and nanosheets of highly packed pore-forming MPs in block copolymers (BCPs). We then integrate these hybrid materials into scalable MP-BCP biomimetic membranes. These MP-BCP nanosheet membranes maintain the molecular selectivity of the three types of β-barrel MP channels used, with pore sizes of 0.8 nm, 1.3 nm, and 1.5 nm. These biomimetic membranes demonstrate water permeability that is 20–1,000 times greater than that of commercial membranes and 1.5–45 times greater than that of the latest research membranes with comparable molecular exclusion ratings. This approach could provide high performance alternatives in the challenging sub-nanometre to few-nanometre size range.

3. Amphiphilic Copolymer Membranes Promote NADH:Ubiquinone Oxidoreductase Activity: Towards an ElectronTransfer Nanodevice

Abstract

Nanoscale devices for energy conversion require the transfer of electrons from one compartment to another. The enzyme complex I, which in vivo mediates electron transfer from NADH to ubiquinone, is an intriguing candidate for this role in nanodevices. However, complex I normally requires the presence of lipids to remain active, potentially limiting its application. Here we demonstrate for the first time that complex I can be actively reconstituted in the synthetic membrane of amphiphilic triblock copolymer vesicles. The functionality of the reconstituted protein was characterized by EPR and activity assays. Its activity is strongly influenced by the molar mass and the block length of the membraneforming polymers, and increases with increasing membrane thickness.

4. Inhibition of Macrophage Phagocytotic Activity by a Receptor-targeted Polymer Vesicle-based Drug Delivery Formulation of Pravastatin

Abstract

Ruptures of macrophage-rich atherosclerotic plaques in the coronary arteries are the main reason for heart attack. Targeted therapeutic interventions with an inhibitory effect on the macrophages promise to be beneficial, but currently available drugs such as statins achieve event reductions of only 30%. Dose-limiting adverse effects in remote organs prohibit achieving higher drug levels known to have strong inhibitory effects on macrophages. Receptor-specific targeting using statin-loaded nanometer-sized triblock copolymer vesicles with targeting moieties might allow high-dose treatment for improved efficacy, while minimizing toxicity in other cells. Vesicle uptake by target cells but not other cell types and slow intracellular content release was observed. A major improvement in biologic efficacy was observed for polymer vesicles compared to free drug, whereas no increased cytotoxicity was observed in muscle cells. Such high-dose, targeted therapy of statins through cell-specific polymer vesicles allows novel treatment paradigms not only for atherosclerosis, but appears promising for a wide range of drugs and diseases.
