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 H2 O2 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
Dendritic cell (DC)-based vaccines have shown promise in adoptive cell therapy for enhancing the antigen-specific response of antitumor immunity. However, their clinical efficacy is limited by the less-presented tumor-associated antigens (TAAs) through MHC I and low lymph node homing efficiency. Herein, to address these issues, we rationally design and fabricate DC-based nanovaccines by coating Cu2-xSe nanoparticles (CS NPs) with the membrane of matured DCs (named as DCNV(CSD) nanovaccines). We reveal the important roles of CS NPs in the DCNV(CSD) nanovaccines from three aspects: (1) inducing the immunogenic cell death of tumor cells to expose abundant TAAs; (2) promoting the escape of TAAs from the lysosomes of DCs during the antigen presenting process through MHC I; (3) sustainably releasing traces of copper ions to promote the proliferation of T cells. Our DCNV(CSD) nanovaccines are characterized with high expressions of MHC I, CD80, CD86, CCR7, and ICAM-1 proteins, which not only endow them with abundantly processed specific TAAs, but also a strong capability of homing to the lymph nodes. The homing capability of our small DCNV(CSD) nanovaccines is better than that of matured DCs. More importantly, they can elicit the strong response of potent antispecific CD8+ T cells for antitumor immunotherapy, as tested in the treatment of highly invasive glioblastoma and highly metastatic melanoma. Additionally, DCNV(CSD) nanovaccines can generate memory T cells (TEM) in the spleen of mice to effectively prevent the recurrence of treated tumors. This work demonstrates a universal approach to fabricate high-performance DC-based nanovaccines for tumor immunotherapy by using versatile CS NPs.

Abstract
This study found a higher percentage of CD8+ T cells in piglets immunized with a CVC1302-adjuvanted inactivated foot-and-mouth disease virus (FMDV) vaccine. We wondered whether the CVC1302-adjuvanted inactivated FMDV vaccine promoted cellular immunity by promoting the antigen cross-presentation efficiency of ovalbumin (OVA) through dendritic cells (DCs), mainly via cytosolic pathways. This was demonstrated by the enhanced levels of lysosomal escape of OVA in the DCs loaded with OVA and CVC1302. The higher levels of ROS and significantly enhanced elevated lysosomal pH levels in the DCs facilitated the lysosomal escape of OVA. Significantly enhanced CTL activity levels was observed in the mice immunized with OVA-CVC1302. Overall, CVC1302 increased the cross-presentation of exogenous antigens and the cross-priming of CD8+ T cells by alkalizing the lysosomal pH and facilitating the lysosomal escape of antigens. These studies shed new light on the development of immunopotentiators to improve cellular immunity induced by vaccines.

Abstract
Skin is the first barrier against external threats, and skin immune dysfunction leads to multiple diseases. Psoriasis is an inflammatory, chronic, common, immune-related skin disease that affects more than 125 million people worldwide. RNA interference (RNAi) therapy is superior to traditional therapies, but rapid degradation and poor cell uptake are the greatest obstacles to its clinical transformation. The transdermal delivery of siRNA and controllable assembly/disassembly of nanodrug delivery systems can maximize the therapeutic effect. Tetrahedral framework nucleic acid (tFNA) is undoubtedly the best carrier for the transdermal transport of genes due to its excellent noninvasive transdermal effect and editability. The authors combine acid-responsive tannic acid (TA), RNase H-responsive sequences, siRNA, and tFNA into a novel transdermal RNAi drug with controllable assembly and disassembly: STT. STT has heightened resistance to enzyme, serum, and lysosomal degradation, and its size is similar to that of tFNA, enabling easy transdermal transport. After transdermal administration, STT can specifically silence nuclear factor kappa-B (NF-κB) p65, thereby maintaining the stability of the skin's microenvironment and reshaping normal skin immune defense. This work demonstrates the advantages of STT in RNAi therapy and the potential for future treatment of skin-related diseases.

Abstract
Chemically modified mRNA (modRNA) has proven to be a versatile tool for the treatment of various cancers and infectious diseases due to recent technological advancements. However, a safe and effective delivery system to overcome the complex extracellular and intracellular barriers is required in order to achieve higher therapeutic efficacy and broaden clinical applications. Here, we explored All-Fect and Leu-Fect C as novel transfection reagents derived from lipopolymers, which demonstrated excellent biocompatibility, efficient delivery capabilities, and a robust ability to escape the lysosomes. These properties directly increase mRNA stability by preventing mRNA degradation by nucleases and simultaneously promote efficient gene translation in vitro and in vivo. The modRNA delivered with lipopolymer vectors sustained effective transfection in mouse hearts following direct intramyocardial injection, as well as in major organs (liver and spleen) after systemic administration. No observable immune reactions or systemic toxicity were detected following the systemic administration of lipopolymer-mRNA complexes to additional solid organs. This study identified commercial reagents for the effective delivery of modRNA and may help facilitate the advancement of gene-based interventions involving the safe and effective delivery of nucleic acid drug substances.

Abstract
Innumerable people worldwide die of cancer every year, although pharmaceutical therapy has actualized many benefits in human health. For background, anti-cancer drug development is difficult due to the multifactorial pathogenesis and complicated pathology of cancers. Cancer cells excrete hydrophobic low-molecular anti-cancer drugs by overexpressed efflux transporters such as multiple drug resistance 1 (MDR1) at the apical membrane. Mutation-driven drug resistance is also developed in cancer. Moreover, the poor distribution of drug to cancer cells is a serious problem, because patients suffer from off-target side effects. Thus, highly selective and effective drug delivery into solid cancer cells across the membrane should be established. It is known that substances (10-100 nm in diameter) such as monoclonal antibodies (mAbs) (approximately 14.2 nm in diameter) or nanoparticles spontaneously gather in solid tumor stroma or parenchyma through the capillary endothelial fenestration, ranging from 200-2000 nm, in neovasculatures due to the enhanced permeability and retention (EPR) effect. Furthermore, cancer antigens, such as HER2, Nectin-4, or TROP2, highly selectively expressed on the surface of cancer cells act as a receptor for receptor-mediated endocytosis (RME) using mAbs against such antigens. Thus, antibody-drug conjugates (ADCs) are promising anti-cancer pharmaceutical agents that fulfill accurate distribution due to the EPR effect and due to antibody-antigen binding and membrane permeability owing to RME. In this review, I introduce the implementation and possibility of highly selective anti-cancer drug delivery into solid cancer cells based on the EPR effect and RME using anti-cancer antigens ADCs with payloads through suitable linkers.

Abstract
The potential of combination therapy using nanoparticle delivery systems in improving triple-negative breast cancer treatment efficacy remains to be explored. Here, we report a novel nanoparticle system using a cholesterol biguanide conjugate hydrochloride (CBH) as both a drug and carrier to load magnolol (MAG). Poly(ethylene glycol)-poly(lactic-co-glycolic acid) (mPEG-PLGA) and aminoethyl anisamide-poly(ethylene glycol)-poly(lactic-co-glycolic acid) (AEAA-PEG-PLGA) were added to form nanoparticles. Nanoparticles accumulated most in tumor tissues when the weight ratio of AEAA-PEG-PLGA to mPEG-PLGA was 4:1. MAG and CBH exerted a synergistic inhibitory effect on 4T1 cells. An in vitro study showed that nanoparticles displayed the highest tumor cell uptake rate, highest apoptosis rate, and strongest inhibitory effect on tumor cell migration and monoclonal formation. CBH might promote nanoparticle uptake by cells and lysosomal escape. After intravenous administration to mice with 4T1 breast tumors in situ, the nanoparticles inhibited tumor growth without obvious toxicity. Western blot results showed that nanoparticles altered the levels of p53, p-AKT, and p-AMPK in the tumor tissue. Moreover, cell apoptosis was found in the same area of H&E-stained and TUNEL-stained tumors treated with the nanoparticles. Collectively, this nanoparticle system provides a novel combination drug delivery strategy for treating triple-negative breast cancer.

Abstract
Membrane lytic peptides (MLP) are widely explored as cellular delivery vehicles or antitumor/antibacterial agents. However, the poor selectivity between cancer and normal cells slims their prospects as potential anti-tumor drugs. Herein, we have developed a rationally designed self-assembly strategy to enhance tumor selectivity of MLP-based conjugates, incorporating a hydrophobic triphenylphosphonium (TPP) group for mitochondria targeting, and a hydrophilic arginine-glycine-aspartic acid (RGD) sequence targeting integrins. The self-assembly nanoparticles can enhance the stability of the peptides in vitro plasma and be endocytosed selectively into the cancer cells. The histidine-rich lytic peptide component assists the disruption of endosomal/lysosomal membranes and subsequent the mitochondria membrane, which leads to apoptosis. This rational design of MLP-based conjugates provides a practical strategy to increase the application prospects of lytic peptides in cancer treatment.

Abstract
Efficiency of standard chemotherapy is dramatically hindered by intrinsic multidrug resistance (MDR). Recently, to amplify therapeutic efficacy, photodynamic therapy (PDT)-induced mitochondrial dysfunction by decorating targeting moieties on nanocarriers has obtained considerable attention. Nevertheless, low targeting efficiency, complex synthesis routes, and difficulty in releasing contents become the major obstacles in further clinical application. Herein, an ingenious liposomal-based nanomedicine (L@BP) was fabricated by encapsulating a mitochondria-anchored photosensitizer (Cy-Br) and paclitaxel (PTX) for realizing enhanced cooperation therapy. At the cellular level, L@BP could hurdle endosomal traps to localize and implement PDT in mitochondria. Intriguingly, the PDT-induced in situ mitochondrial dysfunction led to intracellular ATP reduction, which triggered the downregulated P-glycoprotein transportation capacity and thus resulted in diminishing the efflux of chemotherapeutic agents and increasing drug uptake by drug-resistant cells. The prepared nanomedicine eminently accumulated in the tumor site and acquired enhanced therapeutic efficiency on PTX-resistant lung cancer cells, which possessed great potential in circumventing MDR tumors.

Abstract
BACKGROUND AND PURPOSE Cell penetrating peptides are promising tools for delivery of cargo into cells, but factors limiting or facilitating their cellular uptake are largely unknown. We set out to study the effect of the biophysical properties of the cell membrane on the uptake of penetratin, a cell penetrating peptide. EXPERIMENTAL APPROACH Using labelling with pH-insensitive and pH-sensitive dyes, the kinetics of cellular uptake and endo-lysosomal escape of penetratin were studied by flow cytometry. KEY RESULTS We report that escape of penetratin from acidic endo-lysosomal compartments is retarded compared with its total cellular uptake. The membrane dipole potential, known to alter transmembrane transport of charged molecules, is shown to be negatively correlated with the concentration of penetratin in the cytoplasmic compartment. Treatment of cells with therapeutically relevant concentrations of atorvastatin, an inhibitor of HMG-CoA reductase and cholesterol synthesis, significantly increased endosomal escape of penetratin in two different cell types. This effect of atorvastatin correlated with its ability to decrease the membrane dipole potential. CONCLUSION AND IMPLICATIONS These results highlight the importance of the dipole potential in regulating cellular uptake of cell penetrating peptides and suggest a clinically relevant way of boosting this process.

Abstract
Tumor microenvironment (TME) responsive intelligent system can realize the specific release and uniform distribution of chemotherapy drugs in tumor tissues, to achieve high-efficiency and low-toxic treatment of tumors. In this paper, drug delivery system TKD@RBCm-Mn2O3-ART with the above characteristics was constructed. We synthesized hollow mesoporous manganese trioxide (Mn2O3) nanoparticles and firstly found that they owned time-dependent size transformation feature in simulated TME. The particle size decreased from 318 nm to 50 nm and 6 nm at 1 h and 4 h in simulated TME, respectively. Then artemisinin (ART) was loaded into Mn2O3to realize the co-delivery of Mn2+and ART. The modification of homologous red cell membrane (RBCm) and TKD peptide was aimed at long circulation and tumor targeting in the body.In vitroresults demonstrated that in the presence of GSH, the cumulative drug release percentage could achieve 97.5%. Meanwhile, Mn2O3exhibited a good imaging capability in tumor, with the relaxation rate of 6.3113 mM-1s-1. After entering into MCF-7 cells, TKD@RBCm-Mn2O3/ART synchronously released Mn2+and ART to generate large amount of ROS and induce DNA damage.In vivoresults proved TKD@RBCm-Mn2O3/ART could arrive the deep area of solid tumors and achieve accurate diagnosis and treatment of breast cancer.

Abstract
Orthogonal experiments were used to optimize the process parameters of curcumin TPP-PEG-PCL nanomicelles; the particle size, electric potential and morphology under the electron microscope were systematically detected for the curcumin TPP-PEG-PCL nanomicelles; and the stability and in vitro release of the curcumin TPP-PEG-PCL nanomicelles were investigated. With DID fluorescent dye as the fluorescent probe, flow cytometry was used to study the uptake of nanomicelles by breast cancer cells, and laser confocal microscopy was used to study the mitochondrial targeting and lysosomal escape functions of nanomicelles. Under the same dosage conditions, the effect of curcumin TPP-PEG-PCL nanomicelles on promoting the apoptosis of breast cancer cells was evaluated. The optimal particle size of curcumin TPP-PEG-PCL nanomicelle was(17.3±0.3) nm, and the Zeta potential was(14.6±2.6) mV in orthogonal test. Under such conditions, the micelle appeared as regular spheres under the transmission electron microscope. Fluorescence test results showed that TPP-PEG-PCL nanomicelles can promote drug uptake by tumor cells, escape from lysosomal phagocytosis, and target the mitochondria. The cell survival rate and Hoechst staining positive test results showed that curcumin TPP-PEG-PCL nanomicelles had a good effect on promoting apoptosis of breast cancer cells. The curcumin TPP-PEG-PCL micelles can significantly reduce the mitochondrial membrane potential of breast cancer cells, increase the release of cytochrome C, significantly increase the expression of pro-apoptotic protein Bcl-2 and reduce the expression of anti-apoptotic Bax protein. These test results were significantly better than those of curcumin PEG-PCL nanomicelles and curcumin, with statistically significant differences. The results revealed that curcumin TPP-PEG-PCL nanomicelles can well target breast cancer cell mitochondria and escape from the lysosomal capture, thereby enhancing the drug's role in promoting tumor cell apoptosis.

Abstract
Epithelial cells are known to impede the oral delivery of polypeptides, and the accumulation of mucus and regular dynamic renewal also significantly impede drug absorption. In this work, we prepared a core-shell (COS) nanosystem using poly-N-(2-hydroxypropyl)methacrylamide (pHPMA)/chitosan (CTS). Liraglutide (NN2211) was isolated from the gastrointestinal environment and smoothly passes through the mucous layer. CSKSSDYQC (CSK) peptide and hemagglutinin-2 (HA2) were introduced into the COS nanosystem to establish a complete path from the oral cavity to the epithelial basal side. The fate of nanocapsules in vivo was studied by fluorescence detection. The results showed that the nanocapsules escaped smoothly from the mucus. Taking into account the characteristics of CSK targeting goblet cells, we conducted cell-level studies, and the results showed that after the modification of CSK and pHPMA, more nanocapsules entered the cells. In vitro and in vivo evaluation results showed that the system successfully established a complete path from mucus to epithelial cells by responding to the gastrointestinal environment multiple times.

Abstract
Triple negative breast cancer (TNBC) is insensitive to either chemotherapy or endocrine therapy because of the powerful DNA reparation and the negative expression of surface antigens, which urgently claims for an effective approach to improve the prognosis. Herein, DNA repair blocker BRCA1 small interfering RNA (siRNA) was introduced with cisplatin (Pt) into the elaborately designed pH-sensitive shell-core platform to enhance the chemotherapeutic treatment effect by silencing the DNA repair related gene. In this platform, BRCA1 siRNA and Pt prodrug (Pro-Pt) were separately encapsulated in the porous outer shell and hydrophobic inner core with extremely high encapsulation efficiency and stability effectively preventing them from degradation during circulation. Suitable size and urokinase plasminogen activator analogues (uPA) with high affinity for the uPA receptor (uPAR) realized an excellent dual passive and active tumor targeting ability. Moreover, the exposed PEG hydrophilic chain prevented the nanoparticles (NPs) from precipitating by serum protein or inactivating by nuclease in the blood cycle. Most importantly, the degradable CaP (calcium ions and phosphate ions) shell with smart pH sensitivity would dissipate from NPs in the lysosomes to burst the lysosome membranes so as to guarantee the lysosomal escape and the sequential release of the siRNA and Pro-Pt where the BRCA1 siRNA blocked the DNA repairing pathway followed by reducing Pro-Pt to Pt for irreversible DNA damage. Hence, the uPA-SP@CaP NPs provided a promising strategy for high-efficiency treatment of TNBC along with bringing new hope for more patients.

Abstract
Recently, many researchers have reported that DNA nanostructures, such as tetrahedral framework nucleic acids (tFNAs), have great potential to be useful tools in clinical and laboratory applications due to their programmable shapes, functional sites, and biological responses. However, finite endocytosis and stability in cells and body fluids compromise the functions of DNA nanostructures as a result of various adverse factors. In this study, we successfully synthesized PEGylated protamine, and tFNAs were adsorbed to it in a proper ratio of nitrogen in protamine to phosphorus in tFNAs (N/P ratio) as the functional complex. Furthermore, we demonstrated that PEGylated protamine-adsorbed tFNAs show a more prominent positive effect on cell viability and proliferation than naked tFNAs do. An increase in endocytosis can be observed in three different tissue-derived cells with the PEG-protamine-tFNA (PPT) complex. The increased endocytic ability is mediated by multiple pathways; moreover, the stimulatory effect of the PPT complex on the endocytic ability is dramatically blocked by the inhibition of the caveola-dependent pathway. Consistently, when tFNAs are stabilized by PEGylated protamine, they often tend to escape from lysosomes and survive for a longer period in biological fluids rather than being rapidly eliminated from the kidneys. The in vitro and in vivo results of our study demonstrate that the PPT complex method is a feasible, potent, and low-cost strategy that improves tFNA biocompatibility, stability, and internalization. This study provides evidence supporting the possibility of implementing PPTs for use in drug delivery, bioimaging, and gene transfection in the future.

Abstract
Proteins and peptides are poorly absorbed via oral administration because of the gastrointestinal tract environment and lysosomal digestion after apical endocytosis. A delivery system, consisting of a deoxycholic acid-conjugated nanometer-sized carrier, may enhance the absorption of proteins in the intestine via the bile acid pathway. Deoxycholic acid is first conjugated to chitosan. Liposomes are then prepared and loaded with the model drug insulin. Finally, the conjugates are bound to the liposome surface to form deoxycholic acid and chitosan conjugate-modified liposomes (DC-LIPs). This study demonstrates that DC-LIPs can promote the intestinal absorption of insulin via the apical sodium-dependent bile acid transporter, based on observing fluorescently stained tissue slices of the rat small intestine and a Caco-2 cell uptake experiment. Images of intestinal slices revealed that excellent absorption of DC-LIPs is achieved via apical sodium-dependent bile acid transporter, and a flow cytometry experiment proved that DC-LIPs are a highly efficient delivery carrier. Caco-2 cells were also used to study the lysosome escape ability of DC-LIPs. We learned from confocal microscopy photographs that DC-LIPs can protect their contents from being destroyed by the lysosome. Finally, according to pharmacokinetic analyses, insulin-loaded DC-LIPs show a significant hypoglycemic effect with an oral bioavailability of 16.1% in rats with type I diabetes.

Abstract
Drug-conjugated gold nanoparticles (GNPs), which are generally constructed with many molecules of thiol-terminated polyethylene glycol (PEG)-drug decorated on their surfaces via a thiol-Au covalent bond, are promising and efficient nanoprodrugs. However, because of the exposure of the hydrophobic drug molecules on the surface of the conjugate, in vivo stability, opsonization, and subsequent inefficient therapy become the main issues of this system. To solve these problems without complicating the structures of gold conjugates, herein we propose a method to change the relative position of PEG and the drug. A novel gold conjugate (GNP-NHN═Dox-mPEG) with doxorubicin (Dox) shielded by PEGylation on the surface of GNPs is designed. It demonstrates improved solubility, stability, and dispersion and achieves a two-step stimulus-responsive drug release in response to an acidic environment in lysosomes and then esterase in the cytoplasm. This unique manner of release enables the cytoplasm to act as a reservoir for sustained drug delivery into the nucleus to improve antitumor efficacy in vivo. The intratumoral drug concentrations of the conjugate reach 14.4 ± 1.4 μg/g at 8 h, a two-fold increase in the drug concentration compared with that of the doxorubicin hydrochloride group. This molecular design and regulation approach is facile but important in modulating the in vivo performance of nanovehicles and demonstrates its vital potential in developing effective nanoparticle-based drug delivery agents.

Abstract
Mesenchymal stem cells (MSCs) have a significant self-renewal capacity and can differentiate into a variety of cell types. Cell labeling is crucial as it is difficult to detect cell fate after transplantation in vivo. MSCs labeled with iron oxide nanoparticles (IONPs), which can be tracked by MRI, have tremendous potential in regenerative medicine and oncological research. As a part of nanoparticle, the iron oxide core is a key aspect that can exhibit adverse or beneficial effects on MSCs labeled for tracking. Some IONPs exhibit adverse effects, such as cytotoxicity and apoptosis, while other IONPs exhibit beneficial functions that can promote both MSC proliferation and homing efficiency. This review reveals the cytotoxic mechanisms and potential functions of the iron oxide core of IONPs in cell labeling as well as strategies for minimizing the intracellular effects of IONPs.

Abstract
Theranostic nanoparticles are emerging as potent tools for noninvasive diagnosis, treatment, and monitoring of solid tumors. Herein, an advanced targeted and multistimuli responsive theranostic platform is presented for the intracellular triggered delivery of doxorubicin. The system consists of a polymeric-drug conjugate solid nanoparticle containing encapsulated superparamagnetic iron oxide nanoparticles (IO@PNP) and decorated with a tumor homing peptide, iRGD. The production of this nanosystem is based on a pH-switch nanoprecipitation method in organic-free solvents, making it ideal for biomedical applications. The nanosystem shows sufficient magnetization saturation for magnetically guided therapy along with reduced cytotoxicity and hemolytic effects. IO@PNP are largely internalized by endothelial and metastatic cancer cells and iRGD decorated IO@PNP moderately enhance their internalization into endothelial cells, while no enhancement is found for the metastatic cancer cells. Poly(ethylene glycol)-block-poly(histidine) with pH-responsive and proton-sponge properties promotes prompt lysosomal escape once the nanoparticles are endocyted. In addition, the polymer-doxorubicin conjugate solid nanoparticles show both intracellular lysosomal escape and efficient translocation of doxorubicin to the nuclei of the cells via cleavage of the amide bond. Overall, IO@PNP-doxorubicin and the iRGD decorated counterpart demonstrate to enhance the toxicity of doxorubicin in cancer cells by improving the intracellular delivery of the drug carried in the IO@PNP.
