Abstract
The widespread use of magnetic nanoparticles in modern technologies and medical applications highlights the need for reliable theoretical models that can predict their physical properties. The pair correlation function of two randomly selected superparamagnetic nanoparticles in a ferrofluid/ferrocomposite is studied to depict the joint probability density of the easy magnetisation axes across the planes of parameters of major importance; these are the interaction of ferroparticles with an external magnetic field, the energy of magnetic anisotropy inside the superparamagnetic nanoparticle, and the interparticle magnetic dipole-dipole interaction. Assuming the rotational symmetry of the system, we come to the conclusion that the pair correlations of interest are dependent only on the polar angles, determining the inclinations of the ferroparticle easy axes from the direction of an external magnetic field. The dimer configuration, where two ferroparticles are in close contact along a magnetic field with their easy magnetisation axes aligned, is the most probable. This configuration becomes more pronounced with increasing anisotropy energy, dipolar coupling constant, and external magnetic field.

Abstract
Liver fibrosis is a dynamic pathological process in which the structure and function of the liver abnormally change due to long-term complex inflammatory reactions and chronic liver injury caused by multiple internal and external factors. Previous studies believed that the activation of hepatic stellate cells is a critical part of the occurrence and development of liver fibrosis. However, an increasing number of studies have indicated that the macrophage plays an important role as a central regulator in liver fibrosis, and it directly affects the development and recovery of liver fibrosis. Studies of macrophages and liver fibrosis in the recent 10 years will be reviewed in this paper. This review will not only clarify the molecular mechanism of liver fibrosis regulated by macrophages but also provide new strategies and methods for ameliorating and treating liver fibrosis.

Abstract
Oxidative stress is an important part of the development of NAFLD, and hepatic injury can be prevented by inhibiting oxidative stress. In this study, we investigated the potential role of sinapine in protecting the liver. LPS was selected to establish the oxidative stress model of THLE-2 cells, and the treatment concentrations of LPS (5 μg/mL) and sinapine (5 μM, 20 μM, and 80 μM) were determined by toxicity experiments. The MDA of the sinapine (80 μM) pretreatment group was 1.09 ± 0.13 nmol/mg prot which was reduced by 27.67 % compared with the LPS group. Furthermore, SOD and GSH-Px levels were significantly increased by 40.61 % and 49.60 %, respectively. And the ROS levels of 20 and 80 μM sinapine were reduced by 31.47 % and 40.31 %, respectively (p < 0.01) compared with the model group. The mitochondrial membrane potential had similar results. It was also found that sinapine can significantly down-regulate the level of MCJ protein (p < 0.01), which is related to oxidative stress. Our results indicate that sinapine can maintain liver health by down-regulating the expression of MCJ protein to inhibit oxidative stress, which provides a theoretical basis for the use of sinapine as an inhibitor of MCJ.

Abstract
Nonalcoholic fatty liver disease (NAFLD), recently renamed metabolic-dysfunction-associated fatty liver disease (MAFLD), affects a quarter of the worldwide population. Natural products have been extensively utilized in treating NAFLD because of their distinctive advantages over chemotherapeutic drugs, despite the fact that there are no approved drugs for therapy. Notably, the limitations of many natural products, such as poor water solubility, low bioavailability in vivo, low hepatic distribution, and lack of targeted effects, have severely restricted their clinical application. These issues could be resolved via hepatic targeted drug delivery systems (HTDDS) that boost clinical efficacy in treating NAFLD and decrease the adverse effects on other organs. Herein an overview of natural products comprising formulas, single medicinal plants, and their crude extracts has been presented to treat NAFLD. Also, the clinical efficacy and molecular mechanism of active monomer compounds against NAFLD are systematically discussed. The targeted delivery of natural products via HTDDS has been explored to provide a different nanotechnology-based NAFLD treatment strategy and to make suggestions for natural-product-based targeted nanocarrier design. Finally, the challenges and opportunities put forth by the nomenclature update of NAFLD are outlined along with insights into how to improve the NAFLD therapy and how to design more rigorous nanocarriers for the HTDDS. In brief, we summarize the up-to-date developments of the NAFLD-HTDDS based on natural products and provide viewpoints for the establishment of more stringent anti-NAFLD natural-product-targeted nanoformulations.

Abstract
The liver is a central organ in the human body, coordinating several key metabolic roles. The structure of the liver which consists of the distinctive arrangement of hepatocytes, hepatic sinusoids, the hepatic artery, portal vein and the central vein, is critical for its function. Due to its unique position in the human body, the liver interacts with components of circulation targeted for the rest of the body and in the process, it is exposed to a vast array of external agents such as dietary metabolites and compounds absorbed through the intestine, including alcohol and drugs, as well as pathogens. Some of these agents may result in injury to the cellular components of liver leading to the activation of the natural wound healing response of the body or fibrogenesis. Long-term injury to liver cells and consistent activation of the fibrogenic response can lead to liver fibrosis such as that seen in chronic alcoholics or clinically obese individuals. Unidentified fibrosis can evolve into more severe consequences over a period of time such as cirrhosis and hepatocellular carcinoma. It is well recognized now that in addition to external agents, genetic predisposition also plays a role in the development of liver fibrosis. An improved understanding of the cellular pathways of fibrosis can illuminate our understanding of this process, and uncover potential therapeutic targets. Here we summarized recent aspects in the understanding of relevant pathways, cellular and molecular drivers of hepatic fibrosis and discuss how this knowledge impact the therapy of respective disease.

Abstract
Chronic liver diseases (CLD) are responsible for significant morbidity and mortality worldwide. CLD patients are at a high risk of developing progressive liver fibrosis, cirrhosis, hepatocellular carcinoma (HCC), and subsequent liver failure. To date, there is no specific and effective therapies exist for patients with various forms of CLD. The application of nanotechnology has emerged as a rapidly developing area of interest for the safe and target-specific delivery of poorly aqueous soluble hepatoprotective agents and nucleic acids (siRNA/miRNAs) in CLD. The nanoparticle combination improves bioavailability and plasma stability of drugs with poor aqueous solubility. However, the extent of successful functional delivery of nanoparticles into hepatocytes is often surprisingly low. High Kupffer cells interaction reduces the nanomedicine efficacy. During fibrosis, the extracellular matrix accumulation in the perisinusoidal space restricts nanoparticle delivery to hepatocytes. The availability and uptake of nanoparticles exposure to different cells in the liver microenvironment is as Kupffer cells > sinusoidal endothelial cells > HSCs > hepatocytes. The most widely used strategy to reduce nanoparticles and macrophages interaction is to coat the particle surface with polyethylene glycol. The cationic charged nanoparticles have increased hepatocyte delivery by increased cellular interaction by disrupting the endosomal system via their pH buffering capacity. The immune clearance and toxicity of nanoparticles are mainly unpredictable. Therefore, more elaborate knowledge on exact cellular uptake and intracellular accumulation, trafficking, and endosomal sorting of nanoparticle is the need of the hour to improve the rational carrier design.

Abstract
To date, the search for creating stable ferrofluids with excellent properties for biomedical application is one of the challenging scientific and practical investigations. In this study, novel Fe3O4/Ag nanohybrid ferrofluids from iron sand were synthesized using a double-layer method. The Fe3O4/Ag nanocomposites exhibited stable crystallite sizes of 11.8 12.1 nm and 36.8-37.2 nm for Fe3O4 and Ag, respectively. The lattice parameters of the spinel structure Fe3O4 and face-centered cubic Ag were respectively 8.344 Å and 4.091 Å. With increasing Ag amount, the crystallite phase of Ag in the nanocomposites increased from 40.2% to 77.2%. The XPS results confirmed that Fe3O4/Ag nanocomposites were successfully prepared, where Fe3O4 mixed well with Ag via strong ionic bonding. The FTIR results confirmed the presence of Fe3O4/Ag, oleic acid, and dimethyl sulfoxide as the filler, first layer, and second layer, respectively. The as-prepared ferrofluids exhibited superparamagnetic behavior, where the saturation magnetization decreased with increasing Ag content. The Fe3O4/Ag nanohybrid ferrofluids exhibited excellent antimicrobial performance against Bacillus subtilis, Staphylococcus aureus, Escherichia coli, and Candida albicans. More importantly, the Fe3O4/Ag nanohybrid ferrofluids decreased the progression of liver fibrosis-related inflammation and fibrogenic activity on hepatic stellate cells.

Abstract
With the wide applications of magnetic fields (MFs) in medicine, researchers from different disciplines have gained interest in understanding the effect of various types of MFs on living cells and organisms. In this paper, we mainly focus on the immunological and physical aspects of the immune responses and their mechanisms under different types of MFs. Immune cells were slightly affected by low-frequency alternating MFs but were strongly influenced by moderate-intensity MFs and high-gradient MFs (HGMFs). Larger immune cells, such as macrophages, were more sensitive to HGMFs, which biased the cell polarization into the anti-inflammatory M2 phenotype. Subject to the gradient forces of varying directions and strength, the elongated M2 macrophage also remodeled the cytoskeleton with actin polymerization and changed the membrane receptors and ion channel gating. These alterations were very similar to changes caused by the small GTPase RhoA interference in macrophage. Regulation of iron metabolism may also contribute to the MF effects in macrophages. High MFs were found to regulate the iron content in monocyte-/macrophage-derived osteoclasts by affecting the expression of iron-regulation genes. On the other hand, paramagnetic nanoparticles (NPs) combined with external MFs play an important role in T-cell immunity. Paramagnetic NP-coated T-cells can cluster their T-cell receptors (TCRs) by using an external MF, thus increasing the cell–cell contact and communication followed by enhanced tumor killing capacity. The external MF can also guide the adoptively transferred magnetic NP-coated T-cells to their target sites in vivo, thus dramatically increasing the efficiency of cell therapy. Additionally, iron oxide NPs for ferroptosis-based cancer therapy and other MF-related therapeutic applications with obstacles were also addressed. Furthermore, for a profound understanding of the effect of MFs on immune cells, multidisciplinary research involving both experimental research and theoretical modeling is essential.

Abstract
Spinel ferrite magnetic nanoparticles have attracted considerable attention because of their high and flexible magnetic properties and biocompatibility. In this work, a set of magnetic nanoparticles of cobalt ferrite doped with zinc was synthesized via the eco-friendly sol-gel auto-combustion method. Obtained particles displayed a room-temperature ferromagnetic behavior with tuned by chemical composition values of saturation magnetization and coercivity. The maximal values of saturation magnetization ~74 Am2/kg were found in cobalt ferrite nanoparticles with a 15–35% molar fraction of cobalt replaced by zinc ions. At the same time, the coercivity exhibited a gradually diminishing trend from ~140 to ~5 mT whereas the concentration of zinc was increased from 0 to 100%. Consequently, nanoparticles produced by the proposed method possess highly adjustable magnetic properties to satisfy the requirement of a wide range of possible applications. Further prepared nanoparticles were tested with bacterial culture to display the influence of chemical composition and magnetic structure on nanoparticles-bacterial cell interaction.

Abstract
PURPOSE Gallic acid (GA) is a polyphenolic compound with proven efficacy against hepatic fibrosis in experimental animals. However, it suffers from poor bioavailability and rapid clearance that hinders its clinical investigation. Accordingly, we designed and optimized reverse micelle-loaded lipid nanocapsules (RMLNC) using Box-Behnken design that can deliver GA directly into activated-hepatic stellate cells (aHSCs) aiming to suppress hepatic fibrosis progression. METHODS GA-RMLNC was prepared using soft energy, solvent free phase inversion temperature method. Effects of formulation variables on particle size, zeta potential, entrapment efficiency (EE%) and GA release were studied. In-vivo biodistribution of GA-RMLNC in rats and in-vitro activities on aHSCs were also explored. RESULTS Nano-sized GA-RMLNCs (30.35 ± 2.34 nm) were formulated with high GA-EE% (63.95 ± 2.98% w/w) and physical stability (9 months). The formulated system showed burst GA release in the first 2 h followed by sustained release profile. In-vivo biodistribution imaging revealed that RMLNC-loaded with rhodamine-B accumulated mainly in rats' livers. Relative to GA; GA-RMLNC displayed higher anti-proliferative activities, effective internalization into aHSCs, marked down-regulation in pro-fibrogenic biomarkers' expressions and elevated HSCs' apoptosis. CONCLUSIONS These findings emphasize the promising application of RMLNC as a delivery system in hepatic fibrosis treatment, where successful delivery of GA into aHSCs was ensured via increased cellular uptake and antifibrotic activities.

Tumor-Derived Exosome-Educated Hepatic Stellate Cells Regulate Lactate Metabolism of Hypoxic Colorectal Tumor Cells via the IL-6/STAT3 Pathway to Confer Drug Resistance. Onco Targets Ther 2020; 13:7851-7864. [PMID: 32821126 PMCID: PMC7423356 DOI: 10.2147/ott.s253485] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2020] [Accepted: 07/15/2020] [Indexed: 12/12/2022] Open
Abstract
Purpose Colorectal cancer cells spread to the liver and crosstalk with the microenvironment, and hepatic stellate cells (HSCs) are the major stromal components in the liver. However, the role of the interaction between colorectal tumor cells and HSCs in chemotherapeutic resistance remains unclear. The present study aimed to determine the mechanism of colorectal tumor cells educating the HSCs to reprogram the metabolism of adjacent tumor cells and fuel themselves in the metastatic microenvironment of the liver. Patients and Methods Immunohistochemistry (IHC) examined the expression of the monocarboxylate transporters 1 (MCT1) and lactate dehydrogenase B (LDHB) in colorectal liver metastases (CRLM). The Mann–Whitney U-tests analyzed the association between IL-6 levels and clinical parameters. The mechanisms of normoxic tumor-derived exosomes in the education of HSCs were investigated using IHC and ELISA. The conditioned medium of activated HSCs in the regulation of hypoxic tumor cells was analyzed by CCK-8 and cell apoptosis assays. Results The expression of MCT1 and LDHB was high in the liver metastases of irinotecan-resistant patients, and the high level of IL-6 in the plasma of patients with CRLM was associated with poor response to irinotecan-based chemotherapy. The colorectal tumor-derived exosomes activated HSCs to secrete excessive IL-6. Furthermore, the conditioned medium of activated HSCs enhanced the lactate metabolism of hypoxic tumor cells by activating the IL-6/STAT3 pathway and upregulating the downstream MCT1 and LDHB, in order to confer the resistance of SN38, which is the active metabolite of irinotecan. Conclusion Taken together, the cultured supernatant of normoxic exosome-educated HSCs enhances the lactate metabolism of hypoxic tumor cells via the IL-6/STAT3 pathway, in order to confer the SN38 resistance in a mimic liver metastatic microenvironment.

Front Pharmacol 2020; 11:388. [PMID: 32296336 PMCID: PMC7136425 DOI: 10.3389/fphar.2020.00388] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2019] [Accepted: 03/13/2020] [Indexed: 12/14/2022] Open
Abstract
Hepatic stellate cells (HSCs) are the major profibrogenic cells that promote the pathogenesis of liver fibrosis. The crosstalk between transforming growth factor-β1 (TGF-β1) signaling and lipopolysaccharide (LPS)-induced NF-κB signaling plays a critical role in accelerating liver fibrogenesis. Until now, there have been no FDA-approved drug treatments for liver fibrosis. Barbituric acid derivatives have been used as antiasthmatic drugs in the clinic; however, the effect of barbituric acid derivatives in treating liver fibrosis remains unknown. In this study, we synthesized a series of six barbituric acid (BA) derivatives, and one of the compounds, BA-5, exhibited the best ability to ameliorate TGF-β1-induced HSC activation without overt cytotoxic effects. Then, we treated HSCs and RAW264.7 macrophages with BA-5 to analyze the cross-talk of anti-fibrotic and anti-inflammatory effects. Carbon tetrachloride (CCl4)-induced liver fibrosis mouse model was used to evaluate the therapeutic effects of BA-5. Treatment with BA-5 inhibited TGF-β1-induced α-SMA, collagen1a2, and phosphorylated smad2/3 expression in HSCs. Furthermore, BA-5 treatment reversed the LPS-induced reduction in BAMBI protein and decreased IκBα and NF-κB phosphorylation in HSCs. NF-κB nuclear translocation, MCP-1 secretion, and ICAM-1 expression were also inhibited in BA-5-treated HSCs. Conditioned medium collected from BA-5-treated HSCs showed a reduced ability to activate RAW264.7 macrophages by inhibiting the MAPK pathway. In the mouse model, BA-5 administration reduced CCl4-induced liver damage, liver fibrosis, and F4/80 expression without any adverse effects. In conclusion, our study showed that the barbituric acid derivative BA-5 inhibits HSCs activation and liver fibrosis by blocking both the TGF-β1 and LPS-induced NF-κB signaling pathways and further inhibits macrophages recruitment and activation.
