<div> <div> <div> <p>Conjugation techniques are central to improving intracellular delivery of bioactive small molecules. However, tracking and assessing the overall biological outcome of these constructs remains poorly understood. We addressed this issue by having developed a focused library of heterobivalent constructs based on Rho kinase inhibitors to probe various scenarios. By comparing induction of a phenotype of interest vs. cell viability vs. cellular uptake, we demonstrate that such conjugates indeed lead to divergent cellular outcomes. </p> </div> </div> </div>

Therapeutic Drugs

Recently, polymeric nanoparticles have attracted tremendous interests as a useful tool to encapsulate therapeutic drugs, genes, and proteins for their controlled and sustained delivery. Among them, polymeric hydrogel nanoparticles with thermal and/or pH responsiveness have attracted particular attention [1]. Trehalose, a non-reducing disaccharide of glucose, has been demonstrated to be a potent, nontoxic bioprotectant for stabilizing lipids, proteins, viruses, and blood cells at cryogenic and particularly, ambient temperatures (i.e., cryo and lyopreservation) [2]. However, intracellular delivery of trehalose into small eukaryotic mammalian cells in a large quantity for biostabilization purpose has not been very successful so far [2]. In this study, a thermally responsive polymeric nanocapsule was synthesized and characterized with the aim to encapsulate trehalose for its intracellular delivery.

Potential Use

Microscale hydrogels consisting of macromolecular networks in aqueous continuous phases have received increasing attention because of their potential use in tissue engineering, cell encapsulation and for the storage and release of cargo molecules. However, for applications targeting intracellular delivery, their micrometer-scale size is unsuitable for effective cellular uptake. Nanoscale analogs of such materials are thus required for this key area. Here, we describe a microfluidics/nanofluidics-based strategy for generating monodisperse nanosized water-in-oil emulsions with controllable sizes ranging from 2500 ± 110 nm down to 51 ± 6 nm. We demonstrate that these nanoemulsions can act as templates to form protein nanogels stabilized by supramolecular fibrils from three different proteins. We further show that these nanoparticles have the ability to penetrate mammalian cell membranes and deliver intracellular cargo. Due to their biocompatibility and lack of toxicity, natural protein-based nanoparticles present advantageous characteristics as vehicles for cargo molecules in the context of pharmaceutical and biomedical applications.
