Hierarchically Annular Mesoporous Carbon Derived from Phenolic Resin for Efficient Removal of Antibiotics in Wastewater.

Antibiotics have become a new type of environmental pollutant due to their extensive use. High-performance adsorbents are of paramount significance for a cost-effective and environmentally friendly strategy to remove antibiotics from water environments. Herein, we report a novel annular mesoporous carbon (MCN), prepared by phenolic resin and triblock copolymer F127, as a high-performance adsorbent to remove penicillin, streptomycin, and tetracycline hydrochloride from wastewater. The MCNs have high purity, rich annular mesoporosity, a high surface area (605.53 m2/g), and large pore volume (0.58 cm3/g), improving the adsorption capacity and facilitating the efficient removal of penicillin, streptomycin, and tetracycline hydrochloride from water. In the application of MCNs to treat these three kinds of residual antibiotics, the adsorption amounts of tetracycline hydrochloride were higher than penicillin and streptomycin, and the adsorption capacity was up to 880.6 mg/g. Moreover, high removal efficiency (99.6%) and excellent recyclability were achieved. The results demonstrate that MCN adsorbents have significant potential in the treatment of water contaminated with antibiotics.

Preparation of bioactive glass nanoparticles with highly and evenly doped calcium ions by reactive flash nanoprecipitation.

Nanoscale bioactive glass particles have greater bioactivity than microscale bioactive glass particles, due to their high-specific surface area and fast ion release rate in body fluid. However, preparation of bioactive glass nanoparticles (BGNPs) is difficult since calcium is not easy to be highly doped into the forming silica atom network, leading to an uneven distribution and a low content of calcium. In addition, BGNPs are usually prepared in a dilute solution to avoid agglomeration of the nanoparticles, which decreases the production efficiency and increases the cost. In this work, BGNPs are prepared by a method of the reactive flash nanoprecipitation (RFNP) as well as a traditional sol-gel method. The results indicate that the BGNPs by the RFNP present a smaller size, narrower size distribution, more uniform composition, and better bioactivity than those by the traditional sol-gel method. The obtained BGNPs have uniform compositions close to the feed values. The high and even doping of calcium in the BGNPs is achieved. This successful doping of calcium into nanoparticles by the RFNP demonstrates a promising way to effectively generate high-quality BGNPs for bone repairs.

Extracellular vesicles in bone and tooth: A state-of-art paradigm in skeletal regeneration.

Bone and tooth, fundamental parts of the craniofacial skeleton, are anatomically and developmentally interconnected structures. Notably, pathological processes in these tissues underwent together and progressed in multilevels. Extracellular vesicles (EVs) are cell-released small organelles and transfer proteins and genetic information into cells and tissues. Although EVs have been identified in bone and tooth, particularly EVs have been identified in the bone formation and resorption, the concrete roles of EVs in bone and tooth development and diseases remain elusive. As such, we review the recent progress of EVs in bone and tooth to highlight the novel findings of EVs in cellular communication, tissue homeostasis, and interventions. This will enhance our comprehension on the skeletal biology and shed new light on the modulation of skeletal disorders and the potential of genetic treatment.

Biocompatible Copper-Based Nanocomposites for Combined Cancer Therapy.

Copper (Cu) and Cu-based nanomaterials have received tremendous attention in recent years because of their unique physicochemical properties and good biocompatibility in the treatment of various diseases, especially cancer. To date, researchers have designed and fabricated a variety of integrated Cu-based nanocomplexes with distinctive nanostructures and applied them in cancer therapy, mainly including chemotherapy, radiotherapy (RT), photothermal therapy (PTT), chemodynamic therapy (CDT), photodynamic therapy (PDT), cuproptosis-mediated therapy, etc. Due to the limited effect of a single treatment method, the development of composite diagnostic nanosystems that integrate chemotherapy, PTT, CDT, PDT, and other treatments is of great significance and offers great potential for the development of the next generation of anticancer nanomedicines. In view of the rapid development of Cu-based nanocomplexes in the field of cancer therapy, this review focuses on the current state of research on Cu-based nanomaterials, followed by a discussion of Cu-based nanocomplexes for combined cancer therapy. Moreover, the current challenges and future prospects of Cu-based nanocomplexes in clinical translation are proposed to provide some insights into the design of integrated Cu-based nanotherapeutic platforms.

One-pot synthesis of ternary-emission molecularly imprinted fluorescence sensor based on metal-organic framework for visual detection of chloramphenicol.

In this paper, a ternary-emission fluorescence imprinted polymer was one-pot synthesized by sol-gel method after mixing luminescence metal organic framework, green CdTe and near infrared red CdTe for visual detection of chloramphenicol in food. The ternary-emission fluorescence imprinted sensor showed wider linear range within concentration of 10 pM-0.5 nM and 0.5 nM-4.5 nM, with rapid response time of 3 min and the lower detection limit of 3.8 pM toward chloramphenicol. Meanwhile, NH2-UiO-66 improved the fluorescence sensitivity and response speed, the near-infrared CdTe enhanced the anti-interference ability of the imprinted sensor. Compared with the traditional single-emission and dual-emission fluorescence imprinted sensors, the ternary-emission imprinted sensor provided richer color changes from yellowish green to apricot to orange-salmon to amaranth to purple to final blue. It was applied to detect trace chloramphenicol in food with the recoveries of 98.2-101.2 %, which provided a new way for rapid visual detection of chloramphenicol.

Characterization of microbial community, ecological functions and antibiotic resistance in estuarine plastisphere.

The plastisphere is a new ecological niche. Compared to the surrounding water, microbial community composition associated with the plastisphere is known to differ with functional consequences. Here, this study characterized the bacterial and fungal communities associated with four types of plastisphere (polyethylene, polystyrene, polypropylene and polyvinyl chloride) in an estuarine habitat; assessed ecological functions including carbon, nitrogen, phosphorus and sulfur cycling, and determined the presence of antibiotic resistance genes (ARGs) and human pathogens. Stochastic processes dominated the community assembly of microorganisms on the plastisphere. Several functional genera related to nutrient cycling were enriched in the plastisphere. Compared to surrounding water and other plastisphere, the abundances of carbon, nitrogen and phosphorus cycling genes (cdaR, nosZ and chpy etc.) and ARGs (aadA2-1, cfa and catB8 etc.) were significantly increased in polyvinyl chloride plastisphere. In contrast, the polystyrene plastisphere was the preferred substrate for several pathogens being enriched with for example, Giardia lamblia 18S rRNA, Klebsiella pneumoniae phoE and Legionella spp. 23S rRNA. Overall, this study showed that different plastisphere had different effects on ecological functions and health risk in estuaries and emphasizes the importance of controlling plastic pollution in estuaries. Data from this study support global policy drivers that seek to reduce plastic pollution and offer insights into ecological functions in a new ecological niche of the Anthropocene.

Characterization and modeling of Bragg gratings written in polymer fiber for use as filters in the THz region.

We demonstrate fiber Bragg gratings written in polymer fiber for use in the THz window for the first time. A KrF excimer laser operating at 248 nm was used to inscribe notch-type gratings in single component Topas subwavelength fiber. A transmission loss at the centre wavelength of the grating of 60 dB is observed in short gratings containing only 192 notches. Experimental results and modeling are presented. The gratings are expected to find use in THz signal filtering and chemical or biosensing applications.

Interaction of herbal compounds with biological targets: a case study with berberine.

Berberine is one of the main alkaloids found in the Chinese herb Huang lian (Rhizoma Coptidis), which has been reported to have multiple pharmacological activities. This study aimed to analyze the molecular targets of berberine based on literature data followed by a pathway analysis using the PANTHER program. PANTHER analysis of berberine targets showed that the most classes of molecular functions include receptor binding, kinase activity, protein binding, transcription activity, DNA binding, and kinase regulator activity. Based on the biological process classification of in vitro berberine targets, those targets related to signal transduction, intracellular signalling cascade, cell surface receptor-linked signal transduction, cell motion, cell cycle control, immunity system process, and protein metabolic process are most frequently involved. In addition, berberine was found to interact with a mixture of biological pathways, such as Alzheimer's disease-presenilin and -secretase pathways, angiogenesis, apoptosis signalling pathway, FAS signalling pathway, Hungtington disease, inflammation mediated by chemokine and cytokine signalling pathways, interleukin signalling pathway, and p53 pathways. We also explored the possible mechanism of action for the anti-diabetic effect of berberine. Further studies are warranted to elucidate the mechanisms of action of berberine using systems biology approach.

Effect of ZrN coating by magnetron sputtering and sol-gel processed silica coating on titanium/porcelain interface bond strength.

In this study, a coating technique was applied to improve the bond strength of titanium (Ti) porcelain. ZrN coating was prepared by magnetron sputtering, and silica coating was processed by a sol-gel method. The treated surfaces of the specimens were analyzed by X-ray diffraction, and the Ti/porcelain interface was investigated by scanning electron microscopy (SEM) and energy dispersive spectroscopy. The coated specimens appeared fully coherent to the Ti substrate. The fractured bonding surface was also investigated by SEM. The residual porcelain on the metal surface could be observed in the ZrN group and silica group, but there was no obvious porcelain remaining in the control group. A three-point-bending test showed that the bonding strength of the ZrN group (45.99 ± 0.65 MPa) was higher than the silica group (37.77 ± 0.78 MPa) (P < 0.001) and control group (29.48 ± 1.01 MPa) (P < 0.001), while that of the silica group was significantly higher than the control group (P < 0.001). In conclusion, conditioning the ceramic surface with ZrN and silica coatings resulted in a stronger Ti/porcelain bond. ZrN coating by magnetron sputtering was a more effective way to improve the bond strength between Ti and porcelain compared with sol-gel processed silica coating in this study.

[Effect of triple antibiotic paste on microorganisms in root canals of deciduous teeth].

PURPOSE: To analyze the effect of triple antibiotic paste on root canal microorganisms in periapical periodontitis of different stages. METHODS: Eighty-nine children with periapical periodontitis of deciduous teeth in Department of Stomatology, Children's Hospital of Nanjing Medical University from April 2017 to April 2020 were enrolled, and divided into two groups according to the clinical symptoms and root X-ray films, i.e., acute inflammation group and chronic inflammation group. Samples of infected root canals were collected for bacterial identification, isolation and purification. The detection of microorganisms in the infected root canal and the composition of anaerobic microorganisms were analyzed in both groups. Disk diffusion method was used to observe antimicrobial effects of triple antibiotic paste and calcium hydroxide against common anaerobic bacteria, and the sensitivity of different anaerobic bacteria to triple antibiotic paste. Statistical analysis was completed by SPSS 20.0 software package. RESULTS: The microorganisms in both groups were mainly anaerobic bacteria. The detection rates of aerobes and anaerobic bacteria in the infected root canals had no significant difference between the two groups (P>0.05). The top five anaerobes detected in infected root canals were Peptostreptococcus, Bacteroidetes, Enterococcus faecalis, Porphyromonas gingivalis and Fusobacterium nucleatum. The detection rates of Porphyromonas gingivalis, Fusobacterium nucleatum and Bacteroidetes in infected root canal of acute inflammation group were significantly higher than those of chronic inflammation group, and the detection rate of Enterococcus faecalis was significantly lower than that of chronic inflammation group(P<0.05). The bacteriostatic circle diameter of triple antibiotic paste against Peptostreptococcus, Bacteroidetes, Enterococcus faecalis, Porphyromonas gingivalis and Fusobacterium nucleatum was significantly larger than that of calcium hydroxide(P<0.05). The sensitivity of different anaerobic bacteria to triple antibiotic paste was highest in Enterococcus faecalis, followed by Peptostreptococcus, Porphyromonas gingivalis, Fusobacterium nucleatum, and Bacteroidetes(P<0.05). CONCLUSIONS: Triple antibiotic paste has good antimicrobial effect on the common bacteria in the infected root canal of acute and chronic periapical periodontitis.

[Analysis of the effect of improved ART with high-intensity glass ionomer cement in the treatment of primary caries in children].

PURPOSE: To investigate the effect of improved atraumatic restorative treatment(ART) with high-strength glass ionomer cement in the treatment of primary caries in children. METHODS: From August 2018 to May 2019, 262 children with primary tooth caries who were treated in Children's Hospital of Nanjing Medical University were selected into our study, prospectively. The children were divided into two groups, randomly: ART group (131 cases, 177 teeth) and control group (131 cases, 178 teeth). Children in the control group were treated with conventional cavity preparation and composite resin filling, while those in the ART group were treated with improved high-intensity glass ionomer. The curative effect and satisfaction degree were compared between the two groups. SPSS 19.0 software package was used for data analysis. RESULTS: The overall curative effect in the ART group was better than that of the control group. The cooperation degree of the 2~4 years old children in the ART group was significantly higher than that of the control group(P<0.05). The cooperation degree of the 5 years old children between the two groups had no significant differences(P>0.05). Both groups of children accepted 12 months of follow-up. Three months after treatment, the rate of secondary caries in the ART group was significantly lower than that in the control group, but it was not statistically significant(P>0.05). Six and 12 months after treatment, the rate of secondary caries in the ART group were significantly lower than that in the control group(P<0.05), and the satisfaction of parents in the ART group was significantly higher than that in the control group (P<0.05). CONCLUSIONS: Improved ART with high-intensity glass ionomer cement is more likely accepted by children and their parents, with more willing to accept and cooperate with the treatment. Not only is it easy to operate, but also has a reliable curative effect in children.

[Microplastic-Induced Alterations to Antibiotic Resistance Genes in Seawater].

The increasing and combined pollution of microplastics (MPs) and antibiotic resistance genes (ARGs) in aquatic environments is a great ecological and health concern. However, MP-induced alterations to ARGs in seawater is poorly understood, impeding risk assessment of plastics. We profiled the diversity and abundance of ARGs and mobile genetic elements (MGEs) in seawater after the addition of three different MPs (PE, PVC, and PVA) and 49-day aerated incubation.A total of 20, 35, 42, and 64 ARGs were detected in BLK, PE, PVC, and PVA, with 2, 4, 2, and 3 MGEs, respectively. The absolute abundance of ARGs in the seawater aerated with MPs ranged from 4.01×106 copies ·L-1 to 1.05×108 copies ·L-1. Additionally, the variety and richness of ARGs and MGEs in PVA were significantly higher than in the original seawater, or the seawater aerated with the other two MPs. This indicates that PVA, which is water soluble, could induce more diverse and abundant ARGs in seawater. Significant correlations among ARGs, MGEs, and 16S rRNA genes were observed, implying that the occurrence of MGEs in seawater may accelerate the transmission of ARGs through horizontal gene transfer, and bacterial microorganisms could directly affect the propagation and dissemination of ARGs.

3D-Printed metal-organic frameworks within biocompatible polymers as excellent adsorbents for organic dyes removal.

Three-dimensional (3D) printing technique has received exceptional global attention as it can create a myriad of high-resolution architectures from digital models. In the present study, 3D-printed metal-organic frameworks (MOFs) were shaped into several geometries via direct ink writing, which overcomes the instability and high-pressure drop of powdery MOF during the flow of gas or liquid streams. The inclusion of a blend of calcium alginate and gelatin (CA-GE) as biocompatible binder allowed for easy writing and an enhanced mechanical property. Besides, it was found that the printing geometry (square, hexagon, and circle), MOF loading amount, and MOF size also greatly influenced the adsorptive performance. For instance, the methylene blue adsorption efficiency of CA-GE scaffolds without MOF was only 43.6%, while the printed MOF/CA-GE sample exhibited 99.8% adsorption efficiency at 20 min. Both the inherent microporous structure of MOFs and meso/macroporous structures of the 3D matrix contributed to the excellent adsorption properties towards a variety of organic dyes and their mixtures. Furthermore, the 3D-printed adsorbents can be easily regenerated in dilute acid solution and reused for at least 7 times without performance loss. In contrast, the powdery MOF can only be repeatedly used for at most 2 times.

Downregulation of microRNA-204 increases the expression of matrix metallopeptidase 9 in pediatric patients with pulpitis and Helicobacter pylori infection in the stomach.

The present study examined the expression of microRNA (miRNA or miR)-204 in pulp tissues, blood and saliva from pediatric patients with pulpitis and an underlying Helicobacter pylori (Hp) infection in the stomach, and the mechanism of the associated regulation by miR-204 was assessed. A total of 26 children with pulpitis who received tooth extraction at the Children's Hospital of Nanjing Medical University (Nanjing, China) between December 2014 and August 2016 were diagnosed with Hp infection in the stomach and included in the present study (HP+ group); furthermore, 19 children with pulpitis but without Hp infection in the stomach were enrolled as a control (HP- group). Pulp tissues, blood (serum) and saliva samples were collected from all subjects. Reverse-transcription quantitative polymerase chain reaction was used to determine the expression of miR-204 and matrix metalloproteinase 9 (MMP9) mRNA. Western blot analysis was performed to determine MMP9 protein expression in pulp tissues, while ELISA was performed to measure the contents of MMP9 in serum and saliva. A dual luciferase reporter assay was used to identify the direct interaction between miR-204 and its target protein. The results indicated that Hp infection in the stomach was associated with an upregulation of MMP9 mRNA and protein in pulp tissues, serum and saliva from children with pulpitis. Furthermore, the levels of miR-204 in pulp tissues, serum and saliva from children with pulpitis and Hp infection in the stomach were significantly reduced. miR-204 was confirmed to regulate the expression of MMP9 by directly binding with the 3'-untranslated region of MMP9 mRNA. The present study demonstrated that MMP9 expression in pulp tissues, blood and saliva from children with pulpitis and Hp infection in the stomach was upregulated, while miR-204 expression was downregulated. miR-204 may affect inflammatory processes and other oral diseases in children with pulpitis and Hp infection via MMP9, and may be a potential marker for the detection of Hp infection in children with pulpitis.

Modified Sutureless and Glue-Free Method Versus Conventional Sutures for Conjunctival Autograft Fixation in Primary Pterygium Surgery: A Randomized Controlled Trial.

PURPOSE: To compare the advantages and disadvantages of a modified sutureless and glue-free method with those of conventional sutures for conjunctival autograft fixation in pterygium surgery. METHODS: A prospective randomized controlled study was performed on 73 eyes with primary nasal pterygium. After pterygium excision, the bare sclera was covered with a limbal conjunctival autograft, which was fixed using a modified sutureless and glue-free method in group 1 (39 eyes) and sutures in group 2 (34 eyes). The main outcome measures were operative time, autograft stability, postoperative discomfort, autograft thickness, pterygium recurrence, and complications. RESULTS: The mean operative time was significantly shorter in group 1 (11.9 ± 1.3 minutes) than in group 2 (24.3 ± 6.1 minutes, P < 0.0001). On day 2 postsurgery, the average conjunctival autograft thickness was significantly higher in group 1 (861 ± 340 µm) than in group 2 (577 ± 287 µm, P = 0.034). Subsequently, conjunctival autograft thickness gradually decreased, with no significant difference between groups after 1 week. There were no significant differences in postoperative discomfort between groups, except for a greater foreign body sensation on day 2 and an itching sensation in 1 week in group 2 compared with group 1. Autograft side displacement occurred in 4 patients (10.3%) in group 1; 2 of these 4 developed a granuloma. There was 1 recurrence (2.9%) in group 2. CONCLUSIONS: The modified sutureless and glue-free limbal conjunctival autograft fixation method might be effective and efficient for primary pterygium surgery, with potentially decreased recurrence and postoperative discomfort.

Substrates with patterned topography reveal metastasis of human cancer cells.

In this study, we aimed at studying the effects of engineered and patterned substrates on the migration characteristics of mammalian cancer cell lines. On the shallow topographical patterns, cells from different histological origins showed different migration speed and directionality. We also observed that cells from the same origin showed distinctive behaviour, suggesting these substrate topographies could distinguish cancer subtypes. To eliminate the influence of genetic background, we examined two isogenic subpopulations of ovarian cancer cell lines for their different metastatic activities. While these cell lines showed indistinguishable migration characteristics on a flat substrate, their motilities on the patterned substrates were highly different, suggesting that cancer cells' motilities on these substrates varied in a metastasis-dependent manner. While cells with different metastatic activities showed similar morphology and focal adhesion distribution on flat surface, vinculin aggregated into single cytoplasmic foci in metastatic cells cultured on the engineered substrates. This implies that the topographical patterns on the substrates induced vinculin redistribution in cancer cells with a higher invasive activity. The fabricated platforms with topographical patterns offer a novel in vitro technique for metastasis assessment. Moreover, such platforms could potentially provide the opportunity to sort cells in different metastatic states using advanced pattern designs and features.

Therapeutic effects of curcumin nanoemulsions on prostate cancer.

The therapeutic potential of curcumin (Cur) is hampered by its poor aqueous solubility and low bioavailability. The aim of this study was to determine whether Cur nanoemulsions enhance the efficacy of Cur against prostate cancer cells and increase the oral absorption of Cur. Cur nanoemulsions were developed using the self-microemulsifying method and characterized by their morphology, droplet size and zeta potential. The results showed that the cytotoxicity and cell uptake were considerably increased with Cur nanoemulsions compared to free Cur. Cur nanoemulsions exhibited a significantly prolonged biological activity and demonstrated better therapeutic efficacy than free Cur, as assessed by apoptosis and cell cycle studies. In situ single-pass perfusion studies demonstrated higher effective permeability coefficient and absorption rate constant for Cur nanoemulsions than for free Cur. Our study suggested that Cur nanoemulsions can be used as an effective drug delivery system to enhance the anticancer effect and oral bioavailability of Cur.

Transforming doxorubicin into a cancer stem cell killer via EpCAM aptamer-mediated delivery.

Chemotherapy-resistant cancer stem cells (CSCs) are a major obstacle to the effective treatment of many forms of cancer. To overcome CSC chemo-resistance, we developed a novel system by conjugating a CSC-targeting EpCAM aptamer with doxorubicin (Apt-DOX) to eliminate CSCs. Incubation of Apt-DOX with colorectal cancer cells resulted in high concentration and prolonged retention of DOX in the nuclei. Treatment of tumour-bearing xenograft mice with Apt-DOX resulted in at least 3-fold more inhibition of tumour growth and longer survival as well as a 30-fold lower frequency of CSC and a prolonged longer tumourigenic latency compared with those receiving the same dose of free DOX. Our data demonstrate that a CSC-targeting aptamer is able to transform a conventional chemotherapeutic agent into a CSC-killer to overcome drug resistance in solid tumours.

Multifunctional Poly(L-lactide)-Polyethylene Glycol-Grafted Graphene Quantum Dots for Intracellular MicroRNA Imaging and Combined Specific-Gene-Targeting Agents Delivery for Improved Therapeutics.

Photoluminescent (PL) graphene quantum dots (GQDs) with large surface area and superior mechanical flexibility exhibit fascinating optical and electronic properties and possess great promising applications in biomedical engineering. Here, a multifunctional nanocomposite of poly(l-lactide) (PLA) and polyethylene glycol (PEG)-grafted GQDs (f-GQDs) was proposed for simultaneous intracellular microRNAs (miRNAs) imaging analysis and combined gene delivery for enhanced therapeutic efficiency. The functionalization of GQDs with PEG and PLA imparts the nanocomposite with super physiological stability and stable photoluminescence over a broad pH range, which is vital for cell imaging. Cell experiments demonstrate the f-GQDs excellent biocompatibility, lower cytotoxicity, and protective properties. Using the HeLa cell as a model, we found the f-GQDs effectively delivered a miRNA probe for intracellular miRNA imaging analysis and regulation. Notably, the large surface of GQDs was capable of simultaneous adsorption of agents targeting miRNA-21 and survivin, respectively. The combined conjugation of miRNA-21-targeting and survivin-targeting agents induced better inhibition of cancer cell growth and more apoptosis of cancer cells, compared with conjugation of agents targeting miRNA-21 or survivin alone. These findings highlight the promise of the highly versatile multifunctional nanocomposite in biomedical application of intracellular molecules analysis and clinical gene therapeutics.

Novel targeting of PEGylated liposomes for codelivery of TGF-ß1 siRNA and four antitubercular drugs to human macrophages for the treatment of mycobacterial infection: a quantitative proteomic study.

Tuberculosis (TB) is still a major public health issue in developing countries, and its chemotherapy is compromised by poor drug compliance and severe side effects. This study aimed to synthesize and characterize new multimodal PEGylated liposomes encapsulated with clinically commonly used anti-TB drugs with linkage to small interfering RNA (siRNA) against transforming growth factor-ß1 (TGF-ß1). The novel NP-siRNA liposomes could target THP-1-derived human macrophages that were the host cells of mycobacterium infection. The biological effects of the NP-siRNA liposomes were evaluated on cell cycle distribution, apoptosis, autophagy, and the gene silencing efficiency of TGF-ß1 siRNA in human macrophages. We also explored the proteomic responses to the newly synthesized NP-siRNA liposomes using the stable isotope labeling with amino acids in cell culture approach. The results showed that the multifunctional PEGylated liposomes were successfully synthesized and chemically characterized with a mean size of 265.1 nm. The novel NP-siRNA liposomes functionalized with the anti-TB drugs and TGF-ß1 siRNA were endocytosed efficiently by human macrophages as visualized by transmission electron microscopy and scanning electron microscopy. Furthermore, the liposomes showed a low cytotoxicity toward human macrophages. There was no significant effect on cell cycle distribution and apoptosis in THP-1-derived macrophages after drug exposure at concentrations ranging from 2.5 to 62.5 µg/mL. Notably, there was a 6.4-fold increase in the autophagy of human macrophages when treated with the NP-siRNA liposomes at 62.5 µg/mL. In addition, the TGF-ß1 and nuclear factor-κB expression levels were downregulated by the NP-siRNA liposomes in THP-1-derived macrophages. The Ingenuity Pathway Analysis data showed that there were over 40 signaling pathways involved in the proteomic responses to NP-siRNA liposome exposure in human macrophages, with 160 proteins mapped. The top five canonical signaling pathways were eukaryotic initiation factor 2 signaling, actin cytoskeleton signaling, remodeling of epithelial adherens junctions, epithelial adherens junction signaling, and Rho GDP-dissociation inhibitor signaling pathways. Collectively, the novel synthetic targeting liposomes represent a promising delivery system for anti-TB drugs to human macrophages with good selectivity and minimal cytotoxicity.
