Abstract
BACKGROUND The traumatic spinal cord injury (SCI) can cause immediate multi-faceted function loss or paralysis. Microglia, as one of tissue resident macrophages, has been reported to play a critical role in regulating inflammation response during SCI processes. And transplantation with M2 microglia into SCI mice promotes recovery of motor function. However, the M2 microglia can be easily re-educated and changed their phenotype due to the stimuli of tissue microenvironment. This study aimed to find a way to maintain the function of M2 microglia, which could exert an anti-inflammatory and pro-repair role, and further promote the repair of spinal cord injury. METHODS To establish a standard murine spinal cord clip compression model using Dumont tying forceps. Using FACS, to sort microglia from C57BL/6 mice or CX3CR1GFP mice, and further culture them in vitro with different macrophage polarized medium. Also, to isolate primary microglia using density gradient centrifugation with the neonatal mice. To transfect miR-145a-5p into M2 microglia by Lipofectamine2000, and inject miR-145a-5p modified M2 microglia into the lesion sites of spinal cord for cell transplanted therapy. To evaluate the recovery of motor function in SCI mice through behavior analysis, immunofluorescence or histochemistry staining, Western blot and qRT-PCR detection. Application of reporter assay and molecular biology experiments to reveal the mechanism of miR-145a-5p modified M2 microglia therapy on SCI mice. RESULTS With in vitro experiments, we found that miR-145a-5p was highly expressed in M2 microglia, and miR-145a-5p overexpression could suppress M1 while promote M2 microglia polarization. And then delivery of miR-145a-5p overexpressed M2 microglia into the injured spinal cord area significantly accelerated locomotive recovery as well as prevented glia scar formation and neuron damage in mice, which was even better than M2 microglia transplantation. Further mechanisms showed that overexpressed miR-145a-5p in microglia inhibited the inflammatory response and maintained M2 macrophage phenotype by targeting TLR4/NF-κB signaling. CONCLUSIONS These findings indicate that transplantation of miR-145a-5p modified M2 microglia has more therapeutic potential for SCI than M2 microglia transplantation from epigenetic perspective.

Abstract
Objectives Diabetes mellitus [DM], is a multifaceted metabolic disease, which has become a worldwide threat to human wellness. Over the past decades, an enormous amount of attention has been devoted to understanding how microRNAs [miRNAs], a class of small non-coding RNA regulators of gene expression at the post-transcriptional level, are tied to DM pathology. It has been demonstrated that miRNAs control insulin synthesis, secretion, and activity. This review aims to provide an evaluation of the use of miR-143 and miR-145 as biomarkers for the diagnosis and prognosis of diabetes. Methods The use of miR-143 and miR-145 as biomarkers for the diagnosis and prognosis of diabetes has been studied, and research that examined this link was sought after in the literature. In addition, we will discuss the cellular and molecular pathways of insulin secretion regulation by miR-143/145 expression and finally their role in diabetes. Results In the current review, we emphasize recent findings on the miR-143/145 expression profiles as novel DM biomarkers in clinical studies and animal models and highlight recent discoveries on the complex regulatory effect and functional role of miR-143/145 expression in DM. Conclusion A novel clinical treatment that alters the expression and activity of miR-143/miR-145 may be able to return cells to their natural state of glucose homeostasis, demonstrating the value of using comprehensive miRNA profiles to predict the beginning of diabetes.

Abstract
Diabetic wound healing remains a worldwide challenge for both clinicians and researchers. The high expression of matrix metalloproteinase 9 (MMP9) and a high inflammatory response are indicative of poor diabetic wound healing. H8, a curcumin analogue, is able to treat diabetes and is anti-inflammatory, and our pretest showed that it has the potential to treat diabetic wound healing. However, H8 is highly expressed in organs such as the liver and kidney, resulting in its unfocused use in diabetic wound targeting. (These data were not published, see Table S1 in the Supporting Information.) Accordingly, it is important to pursue effective carrier vehicles to facilitate the therapeutic uses of H8. The use of H8 delivered by macrophage membrane-derived nanovesicles provides a potential strategy for repairing diabetic wounds with improved drug efficacy and fast healing. In this study, we fabricated an injectable gelatin microsphere (GM) with sustained MMP9-responsive H8 macrophage membrane-derived nanovesicles (H8NVs) with a targeted release to promote angiogenesis that also reduces oxidative stress damage and inflammation, promoting diabetic wound healing. Gelatin microspheres loaded with H8NV (GMH8NV) stimulated by MMP9 can significantly facilitate the migration of NIH-3T3 cells and facilitate the development of tubular structures by HUVEC in vitro. In addition, our results demonstrated that GMH8NV stimulated by MMP9 protected cells from oxidative damage and polarized macrophages to the M2 phenotype, leading to an inflammation inhibition. By stimulating angiogenesis and collagen deposition, inhibiting inflammation, and reducing MMP9 expression, GMH8NV accelerated wound healing. This study showed that GMH8NVs were targeted to release H8NV after MMP9 stimulation, suggesting promising potential in achieving satisfactory healing in diabetic treatment.

Abstract
Macrophages play a crucial role in regulating wound healing, as they undergo a transition from the proinflammatory M1 phenotype to the proliferative M2 phenotype, ultimately contributing to a favorable outcome. However, in hyperglycemic and hyper-reactive oxygen species environments, the polarization of macrophages becomes dysregulated, hindering the transition from the inflammatory to proliferative phase and consequently delaying the wound healing process. Consequently, regulating macrophage polarization is often regarded as a potential target for the treatment of diabetic wounds. The role of macrophages in wound healing and the changes in macrophages in diabetic conditions were discussed in this review. After that, we provide a discussion of recent therapeutic strategies for diabetic wounds that utilize macrophage polarization. Furthermore, this review also provides a comprehensive summary of the efficacious treatment strategies aimed at enhancing diabetic wound healing through the regulation of macrophage polarization. By encompassing a thorough understanding of the fundamental principles and their practical implementation, the advancement of treatment strategies for diabetic wounds can be further facilitated.

Abstract
MiRNAs are biomarkers widely used in research but their clinical application is still challenging due to their low expression levels. Current methods for miRNA detection involve separate transcription and quantification for each target, which is costly and unsuitable for large sample sizes. This study provides a strategy for designing and screening miRNA-specific stem-loop reverse transcription (RT) primers, which enable the simultaneous transcription of three miRNAs and U6, and the concurrent detection of miRNA and U6 in the same transcript using TaqMan probes labeled with different dyes. The strategy was successfully employed to establish multiplex RT-PCR and dual-quantitative PCR (qPCR) quantification systems for 21 differentially expressed miRNAs during wound healing. The corresponding system can accurately quantify the cell culture samples containing miR-7a-5p mimic, miR-7a-5p inhibitor, or negative control. In summary, our results demonstrate that this strategy could efficiently accomplish the design, screening, and analysis of stem-loop RT primers for multiplex miRNA detection. Compared with the commercially customized miRNA assay kits, our system showed a higher degree of automation, more accurate qPCR assay capabilities, and lower assay costs, which could provide practical value for clinical diagnosis.

Abstract
Diabetic ulcer is usually seen in people with uncontrolled blood sugar. Reportedly, many factors such as impaired glucose metabolism, and macrovascular and microvascular diseases caused angiogenesis disorders and delayed the healing of diabetic ulcers, thus affecting the body's metabolism, nutrition, and immune function. This study aimed to explore the effect of paeonol on skin wound healing in diabetic rats and the related mechanism. A rat model of diabetic ulcer was established. High glucose-treated mouse skin fibroblasts were co-cultured with M1 or M2-polarized macrophages treated with or without paeonol. H&E and Masson staining were used to reveal inflammatory cell infiltration and collagen deposition, respectively. Immunohistochemistry visualized the expression of Ki67, CD31, and vascular endothelial growth factor (VEGF). Western blot was used to detect interleukin (IL)-1β, tumor necrosis factor (TNF)-α, IL-4, IL-10, CD31, VEGFA, and collagen I/III. The expression of iNOS and arginase 1 was revealed by immunofluorescence staining. Paeonol treatment augmented collagen deposition and the expression of Ki67, CD31, VEGF, and macrophage M2 polarization markers (IL-4 and IL-10) and reduced wound area, inflammatory cell infiltration, and macrophage M1 polarization markers (IL-1β and TNF-α) in the ulcerated area. In vitro, paeonol treatment promoted M2-polarization and repressed M1-polarization in macrophages, thereby improving the repair of cell damage induced by high glucose. Paeonol accelerates the healing of diabetic ulcers by promoting M2 macrophage polarization and inhibiting M1 macrophage polarization.

Abstract
Aim Addressing both inflammation and epithelialization during the treatment of diabetic foot ulcers is an important step, but current treatment options are limited. MiRNA has important prospects in the treatment of diabetic foot refractory wound ulcers. Previous studies have reported that miR-185-5p reduces hepatic glycogen production and fasting blood glucose levels. We herein hypothesized that miR-185-5p might play an important role in the field of diabetic foot wounds. Materials and Methods MiR-185-5p in skin tissue samples from patients with diabetic ulcers and diabetic rats were measured using quantitative real-time PCR (qRT-PCR). The streptozotocin-induced diabetes rat model (male Sprague-Dawley rats) for diabetic wound healing was conducted. The therapeutic potential was observed by subcutaneous injection of miR-185-5p mimic into diabetic rat wounds. The anti-inflammation roles of miR-185-5p on human dermal fibroblast cells were analyzed. Results We found that miR-185-5p is significantly downregulated in diabetic skin (people with DFU and diabetic rats) compared to controls. Further, in vitro upregulation of miR-185-5p decreased the inflammatory factors (IL-6, TNF-α) and intercellular adhesion molecule 1 (ICAM-1) of human skin fibroblasts under advanced glycation end products (AGEs). Meanwhile, the increase of miR-185-5p promoted cell migration. Our results also confirmed that the topical increase of miR-185-5p decreases diabetic wound p-nuclear factor-κB (p-NF-κB), ICAM-1, IL-6, TNF-α, and CD68 expression in diabetic wounds. MiR-185-5p overexpression boosted re-epithelization and expedited wound closure of diabetic rats. Conclusion MiR-185-5p accelerated wound healing of diabetic rats, reepithelization, and inhibited the inflammation of diabetic wounds in the healing process, a potentially new and valid treatment for refractory diabetic foot ulcers.

Abstract
A biophotonic device is fabricated by a 3D printing technique for tumor immunotherapy utilizing a flexible organic light-emitting diode (OLED) with deep blue emission and a gelatin-alginate hydrogel that contains a poly(phenylene vinylene) (PPV) derivative and live immune cells of macrophages (M0-RAW264.7). PPV is excited by the OLED to generate reactive oxygen species (ROS), enabling the macrophages to polarize to the M1 phenotype and secrete cytotoxic cytokines to induce the apoptosis of tumor cells. This strategy provides a new method for fabricating cell-involved biophotonic devices for immunotherapy.

Abstract
ABSTRACT Nowadays, there is limited prevention and treatment for myocardial fibrosis in diabetic cardiomyopathy (DCM). Our study aimed to depict the mechanism of the lncRNA TUG1/miR-145a-5p/Cfl2 axis in DCM and to provide a molecular basis for the study of this disease. Male C57BL/6J mice were intraperitoneally injected with streptozotocin to establish DCM mouse models. The expression levels of lncRNA TUG1, miR-145a-5p, and Cfl2 in myocardial tissues of mice were tested by RT-qPCR or Western blot. Cardiac function was assessed by echocardiography. The contents of Ang-II, TNF-α, and IL-1β were measured using ELISA. The histopathological observation was performed by HE staining and Masson staining. The expression levels of myocardial fibrosis-related genes COL1A1, MMP2, and FN1 were determined by RT-qPCR. In addition, bioinformatics website, RIP assay, pull-down assay, and luciferase activity assay were conducted to verify the relationships of lncRNA TUG1, miR-145a-5p, and Cfl2. In the DCM mouse model, lncRNA TUG1 and Cfl2 expression levels were upregulated and miR-145a-5p expression was downregulated. Downregulation of lncRNA TUG1 improved cardiac function and myocardial fibrosis; decreased COL1A1, MMP2, and FN1 expression levels; as well as TNF-α, IL-1β, and Ang-II contents in myocardial tissues of DCM mice. Upregulation of miR-145a-5p showed the same trend as downregulation of lncRNA TUG1. In addition, upregulating miR-145a-5p reversed the promotion roles of lncRNA TUG1 on myocardial fibrosis in DCM mice, and upregulating Cfl2 compromised the improvement effect of downregulated lncRNA TUG1 on myocardial fibrosis in DCM mice. Mechanistically, there was a binding site between lncRNA TUG1 and miR-145a-5p, and miR-145a-5p had a targeting relationship with Cfl2. This study highlights that lncRNA TUG1 sponges miR-145a-5p to aggravate myocardial fibrosis in DCM mice by promoting Cfl2.

Cha KY, Cho W, Park S, Ahn J, Park H, Baek I, Lee M, Lee S, Arai Y, Lee SH. Generation of bioactive MSC-EVs for bone tissue regeneration by tauroursodeoxycholic acid treatment. J Control Release 2023; 354:45-56. [PMID: 36586671 DOI: 10.1016/j.jconrel.2022.12.053] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2022] [Revised: 12/24/2022] [Accepted: 12/26/2022] [Indexed: 01/02/2023]
Abstract
Extracellular vesicles (EVs) are nano-sized carriers that reflect the parent cell's information and are known to mediate cell-cell communication. In order to overcome the disadvantages of mesenchymal stem cells (MSCs) in cell therapy, such as unexpected differentiation leading to tumorization, immune rejection, and other side effects, EVs derived from MSCs (MSC-EVs) with the tissue regenerative function have been studied as new cell-free therapeutics. However, therapeutic applications of EVs require overcoming several challenges. First, the production efficiency of MSC-EVs should be increased at least as much as the quantity of them are required to their clinical application; second, MSC-EVs needs to show various functionality further, thereby increasing tissue regeneration efficiency. In this study, we treated tauroursodeoxycholic acid (TUDCA), a biological derivative known to regulate cholesterol, to MSCs and investigated whether TUDCA treatment would be able to increase EV production efficiency and tissue regenerative capacity of EVs. Indeed, it appears that TUDCA priming to MSC increases the yield of MSC-EVs >2 times by reducing the cellular cholesterol level in MSCs and increasing the exocytosis-related CAV1 expression. Interestingly, it was found that the EVs derived from TUDCA-primed MSCs (T-EV) contained higher amounts of anti-inflammatory cytokines (IL1RN, IL6, IL10, and IL11) and osteogenic proteins (ALP, RUNX2, BMP2, BMPR1, and BMPR2) than those in control MSC-EVs (C-EV). Besides, it was shown that T-EV not only regulated M1/M2 macrophages differentiation of monocytes, also effectively increased the osteogenic differentiation of MSCs as well as bone tissue regeneration in a bone defect rat model. Based on these results, it is concluded that TUDCA treatment to MSC as a new approach endows EV with high-yield production and functionality. Thus, we strongly believe T-EV would be a powerful therapeutic material for bone tissue regeneration and potentially could be expanded to other types of tissue regeneration for clinical applications.

Valsartan in Combination with Tripterygium Glycosides Protects against Chronic Nephritis via the Toll-Like Receptor 4 Pathway. Anal Cell Pathol 2022; 2022:4807028. [PMID: 36061150 PMCID: PMC9433283 DOI: 10.1155/2022/4807028] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/10/2022] [Accepted: 07/20/2022] [Indexed: 11/17/2022] Open
Abstract
Objective. Valsartan has been studied to exert effects on kidney disease. However, the concrete function of valsartan in combination with tripterygium glycosides in chronic nephritis remained largely unknown. The study was designed to unravel the impacts of valsartan and tripterygium glycosides in chronic nephritis through the Toll-like Receptor 4 (TLR4) pathway. Methods. The renal function indicators such as serum creatinine (Scr), blood urea nitrogen (BUN) and β2 microglobulin (β2-MG), 24 h urine protein (Upro) levels, and blood lipid indicators such as total cholesterol (TC), low-density lipoprotein (LDL-C), triacylglycerol (TG) and high-density lipoprotein (HDL-C), inflammatory factors (e.g., IL-1β and IL-8), and the proportion of T lymphocyte subpopulations (CD4+ and CD8+) were detected in chronic nephritis patients before and after treatment with valsartan alone or valsartan combined with tripterygium glycosides. Symptoms of adverse reactions were recorded. TLR4 expression in the patients’ serum was examined. Results. Compared to patients before treatment, after treatment with valsartan alone or valsartan combined with tripterygium glycosides, the renal function indicators Scr, BUN, and 24 h levels were reduced, and TC, TG, and LDL-C levels were reduced, while HDL-C levels were elevated; inflammatory responses (IL-1β and IL-8) were mitigated; CD4+ ratio and CD4+/CD8+ ratio increased yet CD8+ ratio decreased; TLR4 expression was silenced after treatment. All of the changes were more obvious in patients after being treated with valsartan combined with tripterygium glycosides. Conclusion. Valsartan in combination with tripterygium glycosides protects against chronic nephritis via suppressing the Toll-like Receptor 4 pathway.
