Abstract
Diabetes is a global epidemic accompanied by impaired wound healing and increased risk of persistent infections and resistance to standard treatments. Therefore, there is an immense need to develop novel methods to specifically target therapeutics to affected tissues and improve treatment efficacy. This study aims to use enzyme-responsive nanoparticles for the targeted delivery of an anti-inflammatory drug, dexamethasone, to treat inflammation in diabetes. These nanoparticles are assembled from fluorescently-labeled, dexamethasone-loaded peptide-polymer amphiphiles. The nanoparticles are injected in vivo, adjacent to labeled collagen membranes sub-periosteally implanted on the calvaria of diabetic rats. Following their implantation, collagen membrane resorption is linked to inflammation, especially in hyperglycemic individuals. The nanoparticles show strong and prolonged accumulation in inflamed tissue after undergoing a morphological switch into microscale aggregates. Significantly higher remaining collagen membrane area and less inflammatory cell infiltration are observed in responsive nanoparticles-treated rats, compared to control groups injected with free dexamethasone and non-responsive nanoparticles. These factors indicate improved therapeutic efficacy in inflammation reduction. These results demonstrate the potential use of enzyme-responsive nanoparticles as targeted delivery vehicles for the treatment of diabetic and other inflammatory wounds.

Abstract
With the advent of chemical strategies that allow the design of smart bioconjugates, peptide- and protein-drug conjugates are emerging as highly efficient therapeutics to overcome limitations of conventional treatment, as exemplified by antibody-drug conjugates (ADCs). While targeting peptides serve similar roles as antibodies to recognize overexpressed receptors on diseased cell surfaces, peptide-drug conjugates suffer from poor stability and bioavailability due to their low molecular weights. Through a combination of a supramolecular protein-based assembly platform and a pH-responsive linker, the authors devise herein the convenient assembly of a trivalent protein-drug conjugate. The conjugate should ideally possess distinct features of ADCs such as 1) recognition sites that recognize cell receptor and are arranged on 2) distinct locations on a high molecular weight protein scaffold, 3) a stimuli-responsive linker, as well as 4) an attached payload such as a drug molecule. These AD-like conjugates target cancer cells that overexpress somatostatin receptors, can enable controlled release in the microenvironment of cancer cells through a new pH-responsive biotin linker, and exhibit stability in biological media.

Abstract
Proteins play key roles in most biological processes, and protein dysfunction can cause various diseases. Over the past few decades, tremendous development has occurred in the protein therapeutic market due to the high specificity, low side effects, and low risk of proteins. Currently, all protein drugs on the market are based on extracellular targeting; more than 70% of intracellular targets remain un-druggable. Efficient delivery of cytosolic proteins is of significance for protein drugs, advanced biotechnology and molecular cell biology. Herein, we developed a co-assembly strategy for protein-hexahistidine-metal for intracellular protein delivery. Based on the coordinative interaction between His6 and metal ions, various proteins were encapsulated in situ into nanosized and positively charged protein encapsulation particles(Protein@HmA) through a co-assembly process with a high loading capacity and loading efficiency. Protein@HmA was able to deliver proteins with diverse physicochemical properties through multiple endocytosis pathways, and the protein could quickly escape from endosomes. In addition, the bioactivity of the loaded protein during co-assembly and the intracellular delivery processes were well preserved and could be properly exerted inside cells. Our results demonstrate that this strategy should be a valuable platform for protein delivery and has huge potential in protein-based theranostics. STATEMENT OF SIGNIFICANCE: Intracellular targets with protein drugs may provide a new way for the treatment of many refractory disease. Herein, we developed a co-assembly strategy for protein-hexahistidine-metal for efficient intracellular protein delivery. Based on the coordinative interaction between His6 and metal ions, various proteins were encapsulated in situ into nanosized and positively charged particles (Protein@HmA) with a high loading efficiency. Protein@HmA was able to deliver different proteins through multiple endocytosis pathways, and the protein could quickly escape from endosomes. In addition, the bioactivity of the loaded protein during co-assembly and the intracellular delivery processes were well preserved and could be properly exerted inside cells. This strategy should be a valuable platform for protein delivery and has huge potential in protein-based theranostics.

Abstract
Synthetic assembly within living cells represents an innovative way to explore purely chemical tools that can direct and control cellular behavior. We use a simple and modular platform that is broadly accessible and yet incorporates highly intricate molecular recognition, immolative, and rearrangement chemistry. Short bimodular peptide sequences undergo a programmed sequence of events that can be tailored within the living intracellular environment. Each sequential stage of the pathways beginning with the cellular uptake, intracellular transport, and localization imposes distinct structural changes that result in the assembly of fibrillar architectures inside cells. The observation of apoptosis, which is characterized by the binding of Annexin V, demonstrates that programmed cell death can be promoted by the peptide assembly. Higher complexity of the assemblies was also achieved by coassembly of two different sequences, resulting in intrinsically fluorescent architectures. As such, we demonstrate that the in situ construction of architectures within cells will broaden the community's perspective toward how structure formation can impact a living system.

Abstract
The development of a synthetic code that enables a sequence programmable feature like DNA represents a key aspect toward intelligent molecular systems. We developed herein the well-known dynamic covalent interaction between boronic acids (BAs) and catechols (CAs) into synthetic nucleobase analogs. Along a defined peptide backbone, BA or CA residues are arranged to enable sequence recognition to their complementary strand. Dynamic strand displacement and errors were elucidated thermodynamically to show that sequences are able to specifically select their partners. Unlike DNA, the pH dependency of BA/CA binding enables the dehybridization of complementary strands at pH 5.0. In addition, we demonstrate the sequence recognition at the macromolecular level by conjugating the cytochrome c protein to a complementary polyethylene glycol chain in a site-directed fashion.

Abstract
Nature has evolved an optimal synthetic factory in the form of translational and posttranslational processes by which millions of proteins with defined primary sequences and 3D structures can be built. Nature's toolkit gives rise to protein building blocks, which dictates their spatial arrangement to form functional protein nanostructures that serve a myriad of functions in cells, ranging from biocatalysis, formation of structural networks, and regulation of biochemical processes, to sensing. With the advent of chemical tools for site-selective protein modifications and recombinant engineering, there is a rapid development to develop and apply synthetic methods for creating structurally defined, functional protein nanostructures for a broad range of applications in the fields of catalysis, materials and biomedical sciences. In this review, design principles and structural features for achieving and characterizing functional protein nanostructures by synthetic approaches are summarized. The synthetic customization of protein building blocks, the design and introduction of recognition units and linkers and subsequent assembly into structurally defined protein architectures are discussed herein. Key examples of these supramolecular protein nanostructures, their unique functions and resultant impact for biomedical applications are highlighted.

Abstract
Although gene therapy offers hope against incurable diseases, nonreplicating transduction vectors remain lacking. We have previously characterized a cell-penetrating peptide hPP10 for the delivery of various cargoes; however, whether hPP10 can mediate nucleic acid delivery is still unknown. Here, examining via different ways, we demonstrate that hPP10 stably complexes with plasmid DNA (pDNA) and safely mediates nucleic acid transfection. hPP10 can mediate GFP-, dsRed-, and luciferase-expressing plasmids into cells with nearly the same efficiency as commercial transfection reagents Turbofectin or Lipofect. Furthermore, hPP10 can mediate Cre fusion protein delivery and pDNA transfection simultaneously in the Cre/loxp system in vitro. In addition, hPP10 fused with an RNA-binding domain can mediate delivery of small interfering RNA into cells to silence the reporter gene expression. Collectively, our results suggest that hPP10 is an option for nucleic acid delivery with efficiencies similar to that of commercial reagents.

Abstract
Dynamic covalent chemistry is a versatile and powerful tool that integrates both stable chemical bonds and stimulus responsiveness into the construction of smart biotherapeutics. With minimalistic molecular design, a dynamic covalent protein assembly that incorporates selective targeting and intracellular release upon pH stimulus is presented. The construct comprises an active enzymatic protein core (cytochrome c) self-assembled with cancer cell targeting motifs (somatostatin) through boronic acid/salicylhydroxamate chemistry. The bioorthogonal assembly takes place rapidly under neutral aqueous conditions while the release of the protein is initiated under acidic conditions found within cellular vesicles during uptake. By demonstrating that these modular components act in synergy, we show the broad applicability of such chemical strategies to advance the frontier of modern nanomedicine.

Abstract
Nanoparticles can be used as a smart drug delivery system, when they release the drug only upon degradation by specific enzymes. A method to create such responsive materials is the formation of hydrogel nanoparticles, which have enzymatically degradable crosslinkers. Such hydrogel nanoparticles were prepared by ionotropic gelation sodium alginate with lysine-rich peptide sequences-either α-poly-L-lysine (PLL) or the aggrecanase-labile sequence KKKK-GRD-ARGSV↓NITEGE-DRG-KKKK. The nanoparticle suspensions obtained were analyzed by means of dynamic light scattering and nanoparticle tracking analysis. Degradation experiments carried out with the nanoparticles in suspension revealed enzyme-induced lability. Drugs present in the polymer solution during the ionotropic gelation can be encapsulated in the nanoparticles. Drug loading was investigated for interferon-β (IFN-β) as a model, using a bioluminescence assay with MX2Luc2 cells. The encapsulation efficiency for IFN-β was found to be approximately 25%. The nanoparticles suspension can be used to spray-coat titanium alloys (Ti-6Al-4V) as a common implant material. The coatings were proven by ellipsometry, reflection-absorption infrared spectroscopy, and X-ray photoelectron spectroscopy. An enzyme-responsive decrease in layer thickness is observed due to the degradation of the coatings. The Alg/peptide coatings were cytocompatible for human gingival fibroblasts (HGFIB), which was investigated by CellTiterBlue and lactate dehydrogenase (LDH) assay. However, HGFIBs showed poor adhesion and proliferation on the Alg/peptide coatings, but these could be improved by modification of the alginate with a RGD-peptide sequence. The smart drug release system presented can be further tailored to have the right release kinetics and cell adhesion properties.
