Purpose: This study investigated the nutritional value of Misutkaru with added Gryllus bimaculatus powder (GBM) and its applicability as a healthy functional food.Methods: Chemical analysis of the moisture, crude fat, protein, and mineral contents was performed in accordance with the Association of Official Analytical Chemists (AOAC) guidelines. The amino acid and fatty acid compositions were analyzed using an automatic amino acid analyzer and gas chromatography, respectively. The levels of inflammatory cytokines tumor necrosis factor‑alpha (TNF-α), interleukin 1 beta (IL-1β), and interleukin 6 (IL‑6) induced by lipopolysaccharides in RAW 264.7 cells were measured.Results: The general composition per 100 g of GBM was 41.87 g protein, 19.75 g fat, and 28.52 g carbohydrates. The mineral content per 100 g of GBM was 889.66 mg calcium, 1189.73 mg potassium, 220.36 mg magnesium, 207.51 mg sodium, 694.81 mg phosphorus, and 15.50 mg zinc. In particular, valine (21.361 mg/kg), leucine (29.180 mg/kg), and isoleucine (15.562 mg/kg) were abundant in GBM. GBM also effectively downregulated the production of the inflammatory cytokines TNF-α, IL-1β, and IL-6 in RAW 264.7 macrophages.Conclusion: Misutkaru with added Gryllus bimaculatus powder may have potential for application in the development of food materials or foods to prevent muscle loss in elderly individuals and sarcopenia patients, build muscle, and prevent increase in blood lipid concentrations in middle aged people. In particular, as Gryllus bimaculatus is low in fat and carbohydrates, it can be used as a diet material.

Typha capensis is widely used by traditional healers to treat male fertility, venereal problems and inflammation. There are many molecular targets implicated in the inflammatory process: pro- and anti-inflammatory cytokines such as interleukin 1-β, IL-6, IL-10, IL-12p70, tumor necrosis factor alpha (TNF-α), and IL-8, and other proteins such as COX-2, and iNOS. In order to clarify the anti-inflammatory mechanism of action of compounds isolated from T. capensis, RAW 264.7 macrophages were activated by lipopolysaccharide and pre-treated with T. capensis isolated compounds. Lipopolysaccharide-stimulated RAW macrophages after treatment with T. capensis crude acetone extract resulted in decreasing expression of pro-inflammatory cytokines (TNF-α, IL-6,) and increased expression of immunomodulatory cytokine IL-12 P 70.  Isorhamnetin-3-O-β-D-glucoside and  isorhamnetin 3-O rutinoside increased the expression of pro-inflammatory cytokines TNF-α, but failed to reduce the expression of IL-1β and TNF-α. Isorhamnetin-3-O-β-D-glucoside and isorhamnetin 3-O rutinoside increased the expression of immunomodulatory cytokine IL-12p70. Isorhamnetin-3-O-β-D-glucoside  increased the expression of the anti-inflammatory cytokine IL-10 compared to quercetin and LPS-stimulated macrophages. The effect of isorhamnetin 3-O-rutinoside and isorhamnetin-3-O-β-D-glucoside on molecular targets of inflammation may provide support for the use of T. capensis by traditional healers against inflammation.

Recent studies have shown that mesenchymal stem cells (MSCs) can play a restorative role against degenerative joint diseases in horses. The purpose of this study was to investigate whether fetal bone marrow-derived cells (BMC)-derived nanoparticles (BMC-NPs) can stimulate the survival of equine chondrocytes. Equine fetal BMCs were isolated and characterized, and the role of BMC-NPs s in equine chondrocytes undergoing inflammatory cell death was examined. BMCs have several characteristics, such as the potential to differentiate into chondrocytes and osteocytes. Additionally, BMCs expressed immunoregulatory genes in response to treatment with tumor necrosis factor-alpha (TNF-α) and Interleukin 1 beta (IL-1β). We found that BMC-NPs were taken up by equine chondrocytes. Functionally, BMC-NPs promoted the growth of chondrocytes, and reduced apoptosis induced by inflammatory cytokines. Furthermore, we observed that BMC-NPs upregulated the phosphorylation of protein kinase B (Akt) in the presence of IL-1β, and reduced the phosphorylation of TNF-α-induced activation of extracellular signal-regulated kinase 1/2 (ERK1/2) in the chondrocytes. Cumulatively, our study demonstrated that equine fetal BMC-NPs have the potential to stimulate the survival of chondrocytes damaged by inflammatory cytokines. Thus, BMC-NPs may become an alternative cell-free allogenic therapeutic for degenerative joint diseases in horses.

In this study, we have investigated the impact of vitamin C on the production of pro-inflammatory cytokines (interleukin 1 β (IL-1 β), interleukin 6 (IL-6), interleukin 12p40 (IL-12p40), interferon gamma (IFNγ), and tumor necrosis factor alpha (TNF-α)) in lambs naturally infected by pneumonic pasteurellosis. Of 37 lambs, 18 lambs were identified to have pneumonic pasteurellosis and randomly allocated into two equal groups. Single subcutaneous dose of tulathromycine alone (2.5 mg kg−1) or tulathromycine combined with vitamin C (3 gm kg−1) were administrated to the diseased lambs. The serum levels of IL-1β, IL-6, IFN-γ, and TNF-α were returned to the normal levels in pneumonic lambs treated with the combination therapy. The obtained results indicate the selective influences of vitamin C on pro-inflammatory cytokines production in sera of lambs with pneumonic pasteurellosis and highlights the value of vitamin C as a potential anti-inflammatory drug and ideal immunomodulatory agent.

Abstract Vacuoles are membrane vesicles in eukaryotic cells, the digestive system of cells that break down substances absorbed outside the cell and digest the useless components of the cell itself. Researches on anticancer and intractable diseases using vacuoles are being actively conducted. The practical application of the present study to animals requires the determination of the biocompatibility of vacuole. In the present study, we evaluated the effects of vacuoles isolated from Saccharomyces cerevisiae in RAW 264.7 cells. This showed a significant increase in the production of nitric oxide (NO) produced by macrophage activity. Using Reactive Oxygen Species (ROS) assay, we identified that ROS is increased in a manner dependent on vacuole concentration. Western blot analysis showed that vacuole concentration-dependently increased protein levels of inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2). Therefore, iNOS expression was stimulated to induce NO production. In addition, pro-inflammatory cytokines levels promoted, such as interleukin (IL) 6 (IL-6) and tumor necrosis factor (TNF) α (TNF-α). In summary, vacuoles activate the immune response of macrophages by promoting the production of immune-mediated transporters NO, ROS, and pro-inflammatory cytokines.

The anti-inflammatory and cytotoxic activity of thirty-six extracts of nine Indian medicinal plants were determined by measuring the inhibition of production of nitric oxide (NO), interleukin 1beta (IL-1β) and tumor necrosis factor alpha (TNF-α) in lipopolysaccharide (LPS) stimulated RAW 264.7 cells. Their cytotoxic activity against macrophages was determined by MTT assay. The ethyl acetate (EtOAc) extract of Cassia occidentalis L. (roots) (IC50= 21.3 to 43.1 μg/mL) and Mimosa pudica (whole plant) (IC50 = 31.7 to 47.2 μg/mL) and the dichloromethane (DCM) extract of Leucas cephalotes (whole plant) (IC50= 46.8 to 49.3 μg/mL) exhibited significant anti-inflammatory activity by in vitro inhibition of the production of TNF-α, IL-1β and NO in LPS stimulated RAW 264.7 cells. Furthermore, the five compounds isolated from the ethyl acetate extract of Cassia occidentalis roots were found to suppress LPS-induced IL-1β, TNF-α and NO production in a concentration-dependent manner in these cells at IC50 values ranging from 22.5 to 97.4 μM. Emodin and chrysophanol were also found active in inhibiting pro-inflammatory cytokines in vivo. These findings justify an ethnopharmacological use of C occidentalis roots as an effective herbal remedy for the treatment and prevention of inflammation and associated ailments.

miR-150 was found to target the 3′-untranslated regions of AKT3, and the AKT pathway was affected by SR protein kinase 1 (SRPK1). However, the expression and significance of miR-150, AKT3 and SRPK1 in acute lung injury (ALI) were not clear. Here, we found that the expression of miR-150 was significantly reduced, while the expression of AKT3 and SRPK1 were markedly increased in LPS-treated A549, THP-1 and RAW 264.7 cells. miR-150 significantly decreased levels of pro-inflammatory cytokines IL-1β, IL-6 and TNF-α, reduced the expression of AKT3, but had no impact on SRPK1 expression compared with the control group in LPS-treated A549, THP-1 and RAW 264.7 cells. AKT3 silencing only reduced the production of pro-inflammatory cytokines and showed no effect on miR-150 and SRPK1 expression. Finally, we observed that miR-150 mimics and/or silencing of SRPK1 decreased the expression of AKT3 mRNA. Besides, over-expression of miR-150 or silencing of SRPK1 also reduced the expression of AKT3 protein, which exhibited the lowest level in the miR-150 mimics plus si-SRPK1 group. However, si-SRPK1 had no effect on miR-150 level. In conclusion, miR-150 and SRPK1 separately and cooperatively participate into inflammatory responses in ALI through regulating AKT3 pathway. Increased miR-150 and silenced SRPK1 may be a novel potential factor for preventing and treating more inflammatory lung diseases.

Objective This study aimed to analyze the changes in serum inflammatory cytokines and anti-inflammatory cytokines in patients with gouty arthritis (GA). Methods The clinical data and serum samples in patients with gouty arthritis and those in healthy volunteers were collected in China-Japan Friendship Hospital from July 2018 to January 2019. Serum cytokine concentrations in patients with GA and volunteers (controls) were determined by a chemiluminescence method. The differences in cytokine concentrations were compared between the two groups. Results Concentrations of serum interleukin-1 beta (IL-1ß), tumor necrosis factor-alpha (TNF-α), IL-6, IL-8, and IL-4 were significantly higher in patients with acute GA than in controls. Serum concentrations of IL-1ß, TNF-α, IL-6, IL-8, and immunoglobulin E in patients with remission of GA were significantly lower, whereas concentrations of IL-10 and interferon-γ were significantly higher, compared with those in patients with acute GA. Conclusion This study shows that serum concentrations of IL-1ß, TNF-α, IL-6, IL-8, and IL-4 are significantly elevated in patients with GA, and may be involved in the pathogenesis of GA.

Abstract Background An important contributor to the pathogenesis of the autoimmune disease systemic lupus erythematosus (SLE) is the impaired clearance of apoptotic cells (efferocytosis) and increasing evidence implicates microbiota dysbiosis as another important player. The disease-modifying antirheumatic drug hydroxychloroquine (HCQ) is frequently prescribed for the treatment of SLE. Here, we evaluate changes in efferocytosis and the gut microbiome in mice with pristane-induced lupus (PIL) before and after HCQ administration.Methods PIL mice were studied with or without HCQ and/or resveratrol (RESV). Efferocytosis was determined in RAW 264.7 cells and peritoneal macrophages from mouse ascites fluid. The gut microbiome was analyzed using Illumina sequencing targeting the 16S ribosomal DNA gene (rDNA) amplicon sequencing.Results Both HCQ and RESV enhanced efferocytosis. HCQ also significantly suppressed ascites production of proinflammatory cytokines interleukin (IL)-6 and tumor necrosis factor alpha (TNF-α). The Firmicutes/Bacteriodetes (F/B) ratio was significantly decreased in PIL mice compared with untreated controls (p<0.05). The F/B ratio in PIL mice was increased by HCQ alone and significantly increased by HCQ combined with RESV. Alpha- and beta-diversity differed between mice administered RESV and those that were not. Viable counts of lactic acid bacteria Lactobacillaceae, Lactobacillus and Lactobacillales were increased by RESV plus HCQ treatment.Conclusions In this study, HCQ and RESV enhanced efferocytosis in both RAW 264.7 cells and peritoneal macrophages of PIL mice and suppressed IL-6 and TNF-α production in ascites fluid. The pristane-induced reduction in the F/B ratio was restored by HCQ treatment. SLE treatment should consider the role of the gut microbiome.

Osteoarthritis (OA) is a prevalent joint disease linked to the irreversible degradation of key extracellular cartilage matrix (ECM) components (proteoglycans, type-II collagen) by proteolytic enzymes due to an impaired tissue homeostasis, with the critical involvement of OA-associated pro-inflammatory cytokines (interleukin 1 beta, i.e., IL-1β, and tumor necrosis factor alpha, i.e., TNF-α). Gene therapy provides effective means to re-establish such degraded ECM compounds by rejuvenating the altered OA phenotype of the articular chondrocytes, the unique cell population ubiquitous in the articular cartilage. In particular, overexpression of the highly specialized SOX9 transcription factor via recombinant adeno-associated viral (rAAV) vectors has been reported for its ability to readjust the metabolic balance in OA, in particular via controlled rAAV delivery using polymeric micelles as carriers to prevent a possible vector neutralization by antibodies present in the joints of patients. As little is known on the challenging effects of such naturally occurring OA-associated pro-inflammatory cytokines on such rAAV/polymeric gene transfer, we explored the capacity of polyethylene oxide (PEO) and polypropylene oxide (PPO)-based polymeric micelles to deliver a candidate rAAV-FLAG-hsox9 construct in human OA chondrocytes in the presence of IL-1β and TNF-α. We report that effective, micelle-guided rAAV sox9 overexpression enhanced the deposition of ECM components and the levels of cell survival, while advantageously reversing the deleterious effects afforded by the OA cytokines on these processes. These findings highlight the potentiality of polymeric micelles as effective rAAV controlled delivery systems to counterbalance the specific contribution of major OA-associated inflammatory cytokines, supporting the concept of using such systems for the treatment for chronic inflammatory diseases like OA.

The fruit and root of Clausena lansium are remedy for bronchitis in oriental traditional medicine. Extracts from Clausena lansium are reported to have antioxidant, anti-inflammatory, and anticancer activities. This study is designed to investigate whether the ethanol extract of Clausena lansium (Lour.) Skeels could inhibit the lipopolysaccharides (LPS)-induced inflammatory in RAW 264.7 macrophages and the underlining mechanisms. Enzyme-linked immunosorbent assay (ELISA) and reverse transcription polymerase chain reaction (RT-PCR) are used to detect the secretion of tumor necrosis factor alpha (TNF-α) protein and expression of TNF-α mRNA, respectively. RT-PCR and Western blotting are used to determine the mRNA and protein levels of TLR4, MYD88, and TRAF6, respectively. The extract of Clausena lansium suppressed the expression and secretion of TNF-α, which is released by RAW 264.7 cells after LPS induction. Meanwhile, the expression of TLR4, MYD88, and TRAF6 are decreased by extracts from Clausena lansium. Meanwhile, NBP2-29328, an inhibitor of MYD88, synergistically enhances the inhibiting effect of extract from Clausena lansium. The results imply that ethanol extract from Clausena lansium attenuate macrophage-mediated inflammation and TLR4/MYD88/TRAF6 pathway is its potential target.
