Abstract
Intracellular bacteria are the major cause of serious infections including sepsis and peritonitis, but face great challenges in fighting against the stubborn intracellular small colony variants (SCVs). Herein, the authors have developed nanogels (NGs) to destroy both planktonic bacteria and SCVs and eliminate excessive inflammations for peritonitis and sepsis therapies. Free gentamicin (GEN) and hydroxyapatite nanoparticles (NPs) with GEN loading and mannose grafts (mHAG) are inoculated into ε-polylysine NGs to obtain NG@G1-mHAG2 through crosslinking with phenylboronic acid and tannic acid. The H2O2 consumption after reaction with phenylboronic esters and the elimination of free radicals by tannic acid alleviates the escalated inflammatory status to promote sepsis therapy. After mannose-mediated uptake into macrophages, the acid-triggered degradation of mHAG NPs generates Ca2+ to destabilize lysosomes and the efficient lysosomal escape leads to reversion of hypometabolic SCVs into normal phenotype and their sensitivity to GEN. In a peritonitis mouse model, NG@G1-mHAG2 treatment provides strong and persistent bactericidal effects against both extracellular bacteria and intracellular SCVs and extends survival of peritonitis mice without apparent hepatomegaly, splenomegaly, pulmonary edema, and inflammatory cell infiltration. Thus, this study demonstrates a concise and versatile strategy to eliminate SCVs and relieve inflammatory storms for peritonitis and sepsis therapies without infection recurrence.

Abstract
Traditional liposomes degrade into lower-order micelles when PEGylated to even minor degrees (6-7 mol %) and therefore can offer only limited steric exclusion against opsonization during in vivo delivery. In this work, we present for the first time a liposome coated exclusively by PEGylated phospholipids, utilizing lipid-coated calcium phosphate (CaP) cores of diverse sizes (10-15 nm, 30-40 nm) as well as varying polyethylene glycol (PEG) chain lengths (350-5000 Da). Such fully-PEGylated liposome calcium phosphate (LCP) particles exhibit a PEG chain length-dependent circulation longevity and robust immune evasion, while facilitating both strong accumulation within solid tumors upon intravenous injection and a more rapid and extensive lymphatic drainage upon subcutaneous administration. Further, these fully-PEGylated liposomes remain amenable to active targeting strategies which facilitate improved degrees of focused distribution and nanoparticle uptake, represent a lipid packing density commensurate with the formation of a lipid bilayer, and avoid use of scale-limited physical resuspension methods. We expect such improved delivery properties to translate into improved therapeutic safety and efficacy for a variety of systemic and lymphatic diseases.

Abstract
“Biomimetic” approaches for heterogeneous growth of inorganic coatings have become particularly widespread in biomedical applications, where calcium phosphate (CaP) mineral coatings are used to improve biomedical implants. Changes in coating properties can influence the effects of mineral coatings on adjacent cells, but to date it has not been practical to systematically vary inorganic coating properties to optimize specific cell behaviors. Here, we present an approach to grow CaP mineral coatings in an enhanced throughput format to identify unprecedented capabilities in non-viral gene delivery. Subtle changes in coating properties resulted in widely variable transfection, and optimized coatings led to greater than 10-fold increases in transgene expression by multiple target cell types when compared to standard techniques. The enhanced transfection observed here is substrate-mediated, and related to the characteristics of the local environment near the surface of dissolving mineral coatings. These findings may be particularly translatable to medical device applications.

Abstract
Multifunctional membrane-core nanoparticles, composed of calcium phosphate cores, arginine-rich peptides, cationic and PEGylated lipid membranes, and galactose targeting ligands, have been developed as synthetic vectors for efficient nuclear delivery of plasmid DNA and subsequent gene expression in hepatocytes in vivo. Targeted particles exhibited rapid and extensive hepatic accumulation and were predominantly internalized by hepatocytes, while the inclusion of such peptides in LCP was sufficient to elicit high degrees of nuclear translocation of plasmid DNA. Monocyclic CR8C significantly enhanced in vivo gene expression over 10-fold more than linear CR8C, likely due to a release-favoring mechanism of the DNA/peptide complex. Though 100-fold lower in activity than that achieved via hydrodynamic injection, this formulation presents as a much less invasive alternative. To our knowledge, this is the most effective synthetic vector for liver gene transfer.

Abstract
The development of antiviral agents that have novel mechanisms of action is urgently required in the topical therapy of herpes simplex virus type 2 (HSV-2) infections. We reported previously that topical application of branched 3610-Da polyethylenimine (PEI) exhibited preventative antiviral activity. In this study, to develop therapeutic anti-HSV-2 agents, the most potent PEI combined with ~200 nm-sized liposomes with or without oleic acid (liposomes/PEI) was selected in vitro and further evaluated using in vivo studies. The mechanism of action in vivo was elucidated using PEIs with decreased numbers of primary amine residues, resulting from ethylene carbonate treatment, and polyallylamine, a linear polyamine consisting of primary amines. Cytotoxicity and antiviral activity in vitro, and the appearance of acute herpetic disease and virus yields in mice intravaginally administered with liposomes/PEI were evaluated in cell culture assays and a mouse genital herpes model, respectively. In addition, the cellular association of liposome/PEI was examined by flow cytometry and confocal microscopy. PEI showed higher antiviral activity postinfection than preinfection in vivo. Liposome/PEI and PEI with decreased numbers of primary amine residues at a dose of 0.2 mg PEI/mouse exhibited more potent therapeutic antiviral activity than acyclovir and PEI alone without acute lesion appearance or toxicity pre- or postinfection, but polyallylamine was moderately effective only preinfection. Liposome concentrations were important for the effectiveness of liposome/PEI. This finding suggests that PEI combined with liposomes and with slightly decreased numbers of primary amines may be an effective vaginally administrated antiviral drug, and secondary and tertiary amine residues of PEI may contribute to the inhibitory efficiency against viral infection.

Abstract
Targeted gene delivery using nonviral vectors is a highly touted scheme to reduce the potential for toxic or immunological side effects by reducing dose. In previous reports, TAT polyplexes with DNA have shown relatively poor gene delivery. The transfection efficiency has been enhanced by condensing TAT/DNA complexes to a small particle size using calcium. To explore the targetability of these condensed TAT complexes, LABL peptide targeting intercellular cell-adhesion molecule-1 (ICAM-1) was conjugated to TAT peptide using a polyethylene glycol (PEG) spacer. PEGylation reduced the transfection efficiency of TAT, but TAT complexes targeting ICAM-1 expressing cells regained much of the lost transfection efficiency. Targeted block peptides properly formulated with calcium offer promise for gene delivery to ICAM-1 expressing cells at sites of injury or inflammation.

Abstract
Cell-penetrating peptides (CPPs) are small peptides that can facilitate the uptake of macromolecular drugs, such as proteins or nucleic acids, into mammalian cells. Cytosolic delivery of CPPs could be beneficial to bypass conventional endocytosis in order to avoid degradation in the lysosomes. Oligoarginine conjugates have characteristics similar to CPPs in terms of cell translocation and are used in the intracellular delivery of plasmid DNA. In these cases, oligoarginine length and/or charge are important factors in the cellular uptake of oligoarginine alone. The arginine moiety of oligoarginine-modified particles may also be a decisive factor for vectors to deliver plasmid DNA. Oligoarginine-PEG-lipids can form self-assembled particles and modify the surface of lipid- and polymer-based particles. This review focuses on the influence of: i) oligoarginine-modified particles such as micelles, liposomes and polymer-based particles; ii) the morphology of oligoarginine-PEG-lipid complexed with plasmid DNA by decreasing the charge ratio; and iii) the oligoarginine length in the complex on its cellular uptake, transfection efficiency and uptake mechanism. The oligoarginine length of oligoarginine-modified particle complexed with plasmid DNA governs the cellular uptake pathway that determines the destiny of intracellular trafficking and finally transfection efficiency. The new aspects of surface-functionalized particle vectors with oligoarginine are discussed.

Abstract
Oligoarginine-conjugated lipids ((Arg)n-PEG-lipid) (n=4, 6, 8, and 10: number of arginine residues) are novel gene delivery vectors. We prepared two oligoarginine-modified liposomes using (Arg)n-lipid without and with poly(ethylene glycol) (PEG) spacer ((Arg)n-L and (Arg)n-PEG-L), and investigated the effect of PEG spacer and oligoarginine length of liposomes on cellular uptake, gene transfection, and its mechanism in HeLa cells, using complexes with plasmid DNA (DNA) or oligodeoxynucleotide. Transfection efficiency increased as the number of arginine residues increased and Arg10-PEG-L/DNA complexes (lipoplexes) showed the highest gene transfection efficiency among (Arg)n- and (Arg)n-PEG-lipoplexes. Arg4- and Arg4-PEG-lipoplexes were taken up greatly into cells, but showed lower transfection efficiency than Arg10- and Arg10-PEG-lipoplexes, respectively. The different gene expression by Arg4-L to Arg10-L with or without PEG spacer may be explained by the different intracellular uptake mechanism. The main cellular uptake mechanism of Arg10-L and Arg10-PEG-L was the macropinocytosis pathway, whereas that of Arg4-L and Arg4-PEG-L was not. PEG spacer was more effective for intracellular trafficking than Arg length and surface charge of lipoplex which depends on Arg length at the almost same size of lipoplexes. The findings suggested that Arg10-PEG-L was a superior vector since Arg10 induced the macropinocytosis uptake pathway.
