Down-regulation of NF-κB signalling by methanolic extract of Viola odorata (L.) attenuated in vivo inflammatory and angiogenic responses. Inflammopharmacology 2024:10.1007/s10787-024-01505-z. [PMID: 39030451 DOI: 10.1007/s10787-024-01505-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2024] [Accepted: 06/01/2024] [Indexed: 07/21/2024]
Abstract
Intractable inflammation plays a key role in the progression of autoimmune diseases such as rheumatoid arthritis. Oedema and angiogenesis are the hall marks of chronic inflammation. The current study was aimed to investigate the pharmacological effects of the methanolic extract of Viola odorata (Vo.Me) on inflammation induced oedema and angiogenesis, and to identify the active principles and explore the molecular mechanisms thereof. Various models of inflammation were utilized in rats, including carrageenan- and histamine-induced acute oedema, as well as chronic models of Complete Freund's Adjuvant (CFA)-induced arthritis and cotton pellet-induced granuloma. Anti-angiogenic activity was evaluated by CAM assay followed by quantification of phytoconstituents through HPLC. Effect of Vo.Me treatment on the expression of various mediators (PGE-2 and NO) and genes (IL-1β, TNF-α, NF-κB, and COX-2) were explored by qPCR and ELISA assays. HPLC analysis showed the presence of quercetin, chlorogenic acid, gallic acid, benzoic acid, m-coumaric acid, p-coumaric acid, synergic acid, caffeic acid, vanillic acid, sinapic acid, and cinnamic acid in Vo.Me. Significant dose-dependent inhibition of rats' paw oedema was observed in the Vo.Me administered groups (p < 0.05) in both acute and chronic inflammatory models. Moreover, at a dosage of 500 mg/kg, Vo.Me exhibited a comparable anti-inflammatory effect to indomethacin (p > 0.05). Additionally, Vo.Me demonstrated a remarkable anti-granulomatous activity. Histopathological findings demonstrated amelioration of inflammation in animal paws which were treated with Vo.Me and indomethacin. CAM assay also displayed significant inhibitory effect of Vo.Me on the blood vasculature growth. Vo.Me treatment also caused relatively less gastric irritation and hepatic damage as compared to indomethacin. At a molecular level, the down-regulation of NF-κB signalling leading to the decreased activation of pro-inflammatory mediators (such as IL-1β, TNF-α, and COX-2) and their downstream molecules including prostaglandin E-2 (PGE-2) and nitric oxide (NO), is suggested to be responsible for these diverse anti-inflammatory effects. These findings confirmed the promising anti-inflammatory and anti-angiogenic activities of Vo.Me, which warrant bench-to-bedside translational studies to assess its safety and suitability for clinical usage.

Abstract
Inflammatory bowel disease (IBD) is characterized by inflammatory conditions in the gastrointestinal tract. According to reports, IBD prevalence is increasing globally, with heavy economic and physical burdens. Current IBD clinical treatment is limited to pharmacological methods; therefore, new strategies are needed. Myeloid-derived growth factor (MYDGF) secreted by bone marrow-derived mononuclear macrophages has beneficial effects in multiple inflammatory diseases. To this end, the present study aimed to establish an experimental IBD mouse model using dextran sulfate sodium in drinking water. MYDGF significantly alleviated DSS-induced colitis, suppressed lymphocyte infiltration, restored epithelial integrity in mice, and decreased apoptosis in the colon tissue. Moreover, the number of M1 macrophages was decreased and that of M2 macrophages was increased by the action of MYDGF. In MYDGF-treated mice, the NF-κB and MAPK pathways were partially inhibited. Our findings indicate that MYDGF could mitigate DSS-induced mice IBD by reducing inflammation and restoring epithelial integrity through regulation of intestinal macrophage polarization via NF-κB and MAPK pathway inhibition. KEY MESSAGES: MYDGF alleviated DSS-induced acute colitis. MYDGF maintains colon epithelial barrier integrity and relieves inflammation. MYDGF regulates colon macrophage polarization. MYDGF partially inhibited the activation of NF-κB and MAPK pathway.

Abstract
An immunologic system attacking the body's own tissues is a hallmark of autoimmune disorders, which encompass a wide range of unique conditions. Numerous essential biologic functions, including the regulation of the immune system, inflammation, cell division, and tissue repair, are carried out by cytokines. Natural compounds are an effective treatment for autoimmune illnesses by modulation of inflammatory cytokines and infiltration of leukocytes into the inflamed tissue. Here, anti-arthritic study was carried out using oral administration of Azelaic acid (AzA) for 28 days with doses (20, 40, and 80 mg/kg) in Complete Freund's Adjuvant (CFA) induced arthritis model. AzA ameliorated the adjuvant-induced arthritis by decreasing arthritic score, paw volume, improved body-weight alterations and serum levels of PGE2, 5-LOX and anti-ccp. AzA showed significant down regulation of NF-κB, COX-II, TNF-α, IL-17, IL-1β, IL-6, and up regulation of IL4 and IL10. Hemoglobin and RBCs count remarkably increased and ESR, CRP, platelets, WBCs levels markedly reduced in post treatment. In addition, the weakened SOD (superoxide dismutase), Catalase (CAT), Glutathione (GSH) activity and the increased levels of malondialdehyde (MDA) were all reversed by AzA treatment. And showed improved radiographical and histologic alterations in the structure of the joints. Molecular docking studies targeting COX-II, iNOS, TNF-α, 5-LOX, IL4, IL10, IL-6, and IL-17 establish a correlation between theoretical and experimental results. Results showed that AzA inhibit pro-inflammatory cytokines (COX-II, TNF-α, 5-LOX, IL-17, NF-κB, IL-1β, and IL-6) and increase anti-inflammatory cytokines, which supported the anti-arthritic and immunomodulatory potential of AzA.

Abstract
OBJECTIVES Schisandrin B (Sch B) has been shown to possess anti-inflammatory and antioxidant properties, however, its antirheumatoid arthritis properties and potential mechanism remain unexplored. This study evaluated the potential of Sch B in adjuvant-induced arthritic (AIA) rats. METHODS AIA was induced by injecting 0.1 ml of CFA into the paw of rats and the animals were administered with Sch B (50 mg/kg) for 28 days. The effects of Sch B were evaluated using arthritis severity, serum levels of oxido-inflammatory, and metabolic index parameters. KEY FINDINGS Sch B eased arthritic symptoms by significantly reducing paw swelling and arthritic score and increased body weight gain. Moreover, Sch B alleviated the levels of oxido-inflammatory markers including interleukin-1 beta, interleukin-6, tumor necrosis factor alpha, nuclear factor kappa B, transforming growth factor β1, inducible nitric oxide synthase and malonaldehyde, as well as increased the levels of superoxide dismutase, glutathione, and Nrf2. Sch B also remarkably restored the altered levels of triglyceride, aspartate aminotransferase, lactic acid, pyruvate, phosphoenolpyruvate carboxylase, glucose, hypoxia inducible factor-1 alpha, and vascular endothelial growth factor. In addition, Sch B markedly alleviated p65 expression in the treated AIA rats. CONCLUSION This study suggests that Sch B alleviated AIA by reducing oxidative stress, inflammation, and angiogenesis.

Abstract
Objectives To investigate extracts of the stem bark of Ziziphus jujuba (L.) Gaertn. var. hysudrica Edgew. (Rhamnaceae) for anti-inflammatory activity and isolate the active principle(s). Methods The dry powder was macerated separately in three types of solvents to prepare methanol extract (ME), ethyl acetate extract (EE), and chloroform extract (CE). Following in vitro anti-inflammatory screening, the most active extract was selected to isolate the active compound. Both, the active extract and isolated compound were further tested on rats using the carrageenan-induced inflammation model. The blood and paw tissue were subjected to qPCR, and histopathology, respectively. Key findings CE showed comparatively higher anti-inflammatory activity (85.0-95.0 %) in all in vitro assays, except the heat-induced membrane stabilization model (p < 0.05), and upon column chromatography, it yielded a pure crystalline compound. The compound was a pentacyclic triterpenoid (Lupane), named as hydroxymethyl (3β)-3-methyl-lup-20(29)-en-28-oate (Hussainate). CE (500 mg/kg) and Hussainate (1.0 mg/kg) reduced edema in 5 h after carrageenan administration. The activity of Hussainate was found to be comparable to that of dexamethasone (standard). The possible activity mechanism was the downregulation of tumor necrosis factor-alpha (TNF-α), cyclooxygenase-2 (COX-II), NF-κB, and IL-1β. Conclusions This study reveals that chloroform extract of the stem's bark of Z. jujuba may be used to prepare standardized anti-inflammatory herbal products using Hussainate as an active analytical marker. Hussainate may be used as a lead to develop anti-inflammatory drugs.

Abstract
Onosma bracteatum Wall (O. bracteatum) has been used traditionally for the management of arthritis; however, its therapeutic potential warrants further investigation. This study aimed to evaluate the anti-arthritic effects of the aqueous-ethanolic extract of O. bracteatum leaves (AeOB) in a rat model of complete Freund's adjuvant (CFA)-induced arthritis. Rats were treated with AeOB (250, 500, and 750 mg/kg), indomethacin (10 mg/kg), or a vehicle control from days 8 to 28 post-CFA injection. Arthritic score, paw diameter, and body weight were monitored at regular intervals. X-ray radiographs and histopathological analysis were performed to assess arthritic severity. Inflammatory cytokines tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), and C-reactive protein (CRP) were quantified by qPCR and icromatography. Phytochemical analysis of AeOB revealed alkaloids, flavonoids, phenols, tannins, Saponins, and glycosides. AeOB also exhibited antioxidant potential with an IC50 of 73.22 µg/mL in a DPPH assay. AeOB and diclofenac exhibited anti-inflammatory and anti-arthritic activities. Rats treated with AeOB at 750 mg/kg and indomethacin showed significantly reduced arthritic symptoms and joint inflammation versus the CFA control. The AeOB treatment downregulated TNF-α and IL-6 and decreased CRP levels compared with arthritic rats. Radiography and histopathology also showed improved prognosis. These findings demonstrate the anti-arthritic potential of AeOB leaves.

Abstract
Panicum antidotale has traditionally been used as a poultice to alleviate local inflammation and painful diseases. This study aimed to evaluate the anti-inflammatory, wound-healing, analgesic, and antipyretic potential of its ethanol extract (PAAPEE) in vivo for the first time. In vitro antioxidant assays of Panicum antidotale using a 2,2-diphenyl-1-picrylhydrazyl assay revealed that it showed IC50 of 62.50 ± 6.85 μg/mL in contrast to standard, ascorbic acid, that showed IC50 of 85.51 ± 0.38 μg/mL. Administration of PAAPEE at a dose of 500 mg/kg (PAAPEE-500) displayed 78.44% and 75.13% inhibition of paw edema in carrageenen and histamine-induced edema models. respectively, 6 h post-treatment compared to that of the untreated group. Furthermore, it showed 68.78% inhibition of Freund's complete adjuvant-induced edema 21 days after treatment. It reduced the animal's rectal temperature in the yeast-induced fever model to 99.45 during the fourth h post-treatment. It significantly inhibited abnormal writhing by 44% in the acetic acid-induced pain model. PAE-500 also showed enhancement in wound closure by 72.52% with respect to that of the untreated group on the 10th day post-treatment using the excision healing of wound model. Histopathological examination of skin samples confirmed this improvement, showing enhanced tissue architecture with minimal infiltration of inflammatory cells. High-performance liquid chromatography (HPLC) of PAAPEE revealed the presence of quercetin, gallic, p-coumaric, benzoic, chlorogenic, syringic, ferulic, cinnamic, and sinapic acids. Molecular docking of 5-lipoxygenase and glycogen synthase kinase-3 β protein indicated their potential interaction within the active sites of both enzymes. Thus, P. antidotale serves as an effective natural wound-healing, anti-inflammatory, analgesic, and antipyretic agent.

Abstract
Rheumatoid arthritis (RA) is classified as a chronic inflammatory autoimmune disorder, associated with a varied range of immunological changes, synovial hyperplasia, cartilage destructions, as well as bone erosion. The infiltration of immune-modulatory cells and excessive release of proinflammatory chemokines, cytokines, and growth factors into the inflamed regions are key molecules involved in the progression of RA. Even though many conventional drugs are suggested by a medical practitioner such as DMARDs, NSAIDs, glucocorticoids, etc., to treat RA, but have allied with various side effects. Thus, alternative therapeutics in the form of herbal therapy or phytomedicine has been increasingly explored for this inflammatory disorder of joints. Herbal interventions contribute substantial therapeutic benefits including accessibility, less or no toxicity and affordability. But the major challenge with these natural actives is the need of a tailored approach for treating inflamed tissues by delivering these bioactive agentsat an appropriate dose within the treatment regimen for an extended periodof time. Drug incorporated with wide range of delivery systems such as liposomes, nanoparticles, polymeric micelles, and other nano-vehicles have been developed to achieve this goal. Thus, inclinations of modern treatment are persuaded on the way to herbal therapy or phytomedicines in combination with novel carriers is an alternative approach with less adverse effects. The present review further summarizes the significanceof use of phytocompounds, their target molecules/pathways and, toxicity and challenges associated with phytomolecule-based nanoformulations.

Abstract
The present research study aims to appraise the potential of polyphenol-rich extracts from two Brassica rapa varieties on antioxidant, anti-inflammatory and analgesic activities using carrageenan-induced paw edema model in rats. Methanol extracts of peels and pulps of Brassica rapa yellow root (BRYR) and Brassica rapa white root (BRWR) were prepared using the soxhlet extraction technique. All four extracts were analyzed by reversed-phase high-pressure liquid chromatography (RP-HPLC) for the polyphenols, and results showed that 10 phenolic acids and 4 flavonoids were detected. Gallic acid was the major phenolic acid (174.6-642.3 mg/100 g of dry plant material) while catechin was the major (34.45-358.5 mg/100 g of dry plant material) flavonoid detected in the extracts. The total phenolic contents (TPC) of BRYR peel, BRWR peel, BRYR pulp and BRWR pulp extracts were in the range of 1.21-5.01 mg/g of dry plant material, measured as GAE, whereas the total flavonoid contents (TFC) were found in the range of 0.90-3.95 mg/g of dry plant material, measured as QE. BRYR peel extract exhibited the best DPPH radical scavenging activity (IC50, 3.85 µg/mL) and reducing potential as compared with other extracts. The in vivo anti-inflammatory potential was assessed by carrageenan-induced rat paw edema, and the analgesic potential was investigated by a hot plate test. Suppression of biochemical inflammatory biomarkers including C-reactive protein (CRP), rheumatoid factor (RF) and tumor necrosis factor (TNF-α), and interleukin-6 (IL-6) concentration were also determined. Results showed that BRYR peel extracts reduced paw edema and suppressed the production of TNF-α, IL-6, CRP and RF most significantly, followed by BRWR peel, BRYR pulp and BRWR pulp extracts. In addition, histopathology observation also supports the anti-inflammatory effect of peel extracts as being greater than that of root pulp extracts. Moreover, it was observed that the analgesic effect of the root-peel extracts was also more pronounced as compared with root-pulp extracts. It can be concluded that BRYR peel extract has higher phenolic contents and showed higher suppression of TNF-α, IL-6, CRP and RF, with strong antioxidant, anti-inflammatory and analgesic effects.

Abstract
Traditional use of Cassia absus as an anti-inflammatory in conjunctivitis and bronchitis is well reported. Owing to its anti-inflammatory potential, the current study appraised in vivo anti-arthritic activity of n-hexane and aqueous extracts of Cassia absus seeds (200 mg/kg) using Complete Freund's Adjuvant (CFA) rat model of arthritis. Changes in paw size (mm), joint diameter (mm), and pain response (sec) were recorded at the baseline and then after CFA induction at the interval of 4 days till the 28th day. Blood samples of anesthetized rats were collected for the estimation of hematological, oxidative, and inflammatory biomarkers. Results showed percent inhibition in paw edema (45.09% and 60.79%) with both n-hexane and aqueous extracts, respectively. Significant reduction in paw size and ankle joint diameter (P < 0.01) was seen in extracts treated rats. Erythrocyte Sedimentation rate, C-Reactive Protein, White Blood Cell levels significantly lowered, and Hemoglobin, Platelets and Red Blood Cell count significantly increased post-treatments. Superoxide Dismutase, Catalase, and Glutathione were significantly improved (P < 0.0001) in treated groups as compared to CFA induced arthritic control. Real-time polymerase chain reaction investigation showed significant downregulation (P < 0.05) of Interleukin-1β, Tumor Necrosis Factor-α, Interleukin-6, Cycloxygenase-2, Nuclear Factor-κB, Prostaglandin E Synthase 2, Interferon Gamma and upregulation of Interleukin-4, Interleukin-10 in both n-hexane and aqueous extract-treated groups. It is thereby concluded that Cassia absus can significantly attenuate CFA-induced arthritis by modulation of oxidative and inflammatory biomarkers.

Abstract
Diosgenin (DGN) is a well-known steroidal sapogenin that is obtained from the hydrolysis of dioscin. The current research aimed to explore the anti-inflammatory and anti-arthritic potential of DGN alone and in combination with methotrexate (MTX). The in-vitro antioxidant, and anti-arthritic potential was assessed by protein denaturation and Human red blood cell membrane stabilization assays. The in-vivo anti-inflammatory effect was examined by carrageenan-induced paw edema and xylene-induced ear edema methods. The arthritis was induced in Wistar rats by inoculation of 0.1 ml Complete Freund's adjuvant in the left hind paw at day 1. The arthritic animals received MTX 1 mg/kg as standard, DGN at 5, 10, 20 mg/kg, and a combination treatment (DGN 20 mg/kg + MTX) was administered orally from 8 to 28th day while normal and disease control received normal saline. DGN at 1600 μg/ml exhibited the highest in-vitro activities in contrast to other tested concentrations. DGN at 20 mg/kg exhibited the maximum (p < 0.05-0.0001) inhibition of inflammation in carrageenan and xyleneinduced edema models. Treatment with DGN and MTX alone and in combination significantly reduced the paw diameter, body weight, arthritic index, and pain. It restored altered blood parameters and oxidative stress biomarkers in contrast to the diseased control rats. DGN profoundly (P < 0.0001) downregulated mRNA expression of TNF-α, IL-1β, NF-ĸβ, and COX-2 while upregulated IL-4 and -10 in treated rats. The combination of DGN with MTX showed the highest therapeutic efficacy than individual therapy, so it can be used as an adjunct for rheumatoid arthritis treatment.

Abstract
Inflammation is the core contributor in the pathogenesis of various acute and chronic illness including appendicitis, bronchitis, arthritis, cancer and neurological diseases. NSAIDs, commonly used medications for inflammatory diseases, on prolonged use cause GI bleeding, ulcers and many more issues. Plant-based therapeutic agents including essential oils in combination with low-dose synthetic drugs have been shown to produce synergistic effects and reduce complications of synthetic drugs. This study was designed to evaluate the anti-inflammatory, analgesic and anti-pyretic properties of Eucalyptus globulus essential oil alone and in combination with flurbiprofen. GC-MS analysis was performed to screen chemical composition of oil. In vitro anti-inflammatory assay (membrane stabilization assay) and in vivo inflammatory acute (carrageenan and histamine-induced paw oedema) and chronic (cotton pellet-induced granuloma and Complete Freund's adjuvant-induced arthritis) models were performed to check anti-inflammatory properties. Acetic acid-induced algesia and yeast-induced pyrexia models were performed to check analgesic and anti-pyretic properties. qRT-PCR was performed to study the effect of treatments on the expression of inflammatory biomarkers. GC-MS analysis of E. globulus essential oil showed the presence of eucalyptol along with other active biomolecules. 500 + 10 mg/kg of oil-drug combination showed significantly (p < 0.05) better in vitro membrane stabilization effects as compared with groups treated with 500 mg/kg of E. globulus oil and 10 mg/kg of Flurbiprofen alone. 500 + 10 mg/kg of oil-drug combination showed significantly (p < 0.05) better anti-inflammatory, analgesic and antipyretic effects as compared to 500 mg/kg of E. globulus oil alone in all in vivo models. When comparison was done between 500 + 10 mg/kg of oil-drug combination-treated and 10 mg/kg Flurbiprofen-treated group, the former group showed significantly (p < 0.05) better anti-inflammatory and anti-pyretic effects, but there were non-significant differences in the analgesic model. Animal group treated with 10 mg/kg of Flurbiprofen showed significantly (p < 0.05) better anti-inflammatory and analgesic effects than group treated with 500 mg/kg of oil alone while, there were non-significant differences in anti-pyretic effects. qRT-PCR analysis showed significant (p < 0.05) down-regulation in the expression of IL-4 and TNF-α in serum samples of animals treated with 500 + 10 mg/kg of oil-drug combination as compared to the diseased control (arthritic) group. Overall, the current research demonstrates that Eucalyptus globulus essential oil in combination with flurbiprofen showed better anti-inflammatory, analgesic and anti-pyretic effects than oil and flurbiprofen alone which is attributed to the down-regulation of pro-inflammatory biomarkers (IL-4 and TNF-α). Further studies are required to formulate a stable dosage form and to check the anti-inflammatory efficacy in different inflammatory disorders.

Abstract
This study investigated the anti-arthritic potential of novel mannich-based derivatives of 2-mercaptobenzimidazole (AK7 and AK9) in rats. The compounds were characterized by NMR and FTIR spectroscopies and their acute anti-inflammatory effects were measured by carrageenan (CRG)-induced paw edema model. The most potent doses of AK7 and AK9 were subsequently evaluated in the complete Freund's adjuvant (CFA)-induced inflammatory arthritis model. AK7 and AK9 inhibited CRG-induced inflammation in a dose-dependent fashion and a similar reduction in CFA-induced paw inflammation was observed. Moreover, X-ray and histopathological analyses of AK7-treated animals displayed normal joint structure whereas AK9, despite of its anti-inflammatory effects, failed to protect against cartilage destruction. Interestingly, biochemical analysis revealed a better safety profile for AK7 than for AK9 and methotrexate. Both compounds suppressed mRNA levels of pro-inflammatory mediators (IRAK1, NF-κB1, TNF-α, IL1B) while only AK7 reduced the transcript levels of interstitial collagenase (MMP1). Molecular docking analysis of AK7 and AK9 with TNF-α and MMP1 also supported the experimental data. These findings clearly highlight the beneficial effects of AK7 in the prevention and/or treatment of inflammatory arthritis.

Abstract
PURPOSE The present study was carried out to evaluate anti-inflammatory and antiangiogenic attributes of simvastatin and its nanofilms containing silver nanoparticles. METHODS Silver nanoparticles and simvastatin-loaded nanocomposite (SNSN) films were formulated by using polymeric solution (pectin + sericin) through casting solution method. Different in vitro and in vivo anti-inflammatory assays were performed. In addition, chick chorioallantoic membrane assay (CAM) was also employed for angiogenesis activity. RESULTS FTIR spectra of the film depicted the presence of intact simvastatin. Differential scanning calorimetry exhibited no endothermic expression in F9 film thermogram. The simvastatin release from all films exhibited a burst effect. Cotton-pellet induced granuloma model study showed that high dose of simvastatin and indomethacin produced comparable (p < 0.05) anti-inflammatory effect. Noteworthy, RT-PCR showed dose-dependent, anti-oedematous effect of simvastatin through downregulation of serum TNF-α and interleukin-1ß levels. While results of CAM assay exhibited remarkable anti-angiogenic potential of SNSN films showing dissolved blood vessels network macroscopically. CONCLUSION To reiterate, simvastatin and its SNSN films can add significant contribution to the field of biomedicines due to their promising anti-inflammatory and antiangiogenic properties, however, clinical studies are required to validate their commercial use.

Abstract
Rheumatoid arthritis is a chronic inflammatory disorder of polyarticular tissues, characterised by progressive synovitis. Its prolonged treatment imparts a huge burden on the healthcare system and results in toxicity, which necessitates the search for safe, efficacious and cost-effective therapies. Diospyros malabarica (Desr.) Kostel is traditionally used for anti-inflammatory purposes; however, to the best of our knowledge, there is no detailed study reporting the in vivo anti-inflammatory potential of this plant. Therefore, in the current study, the methanol extract of D. malabarica (Desr.) Kostel fruit (mDMF) was evaluated for its antioxidant, anti-inflammatory and anti-arthritic potentials, along with its underlying mechanisms. The antioxidant activity was evaluated by DPPH assay. Total phenolic and flavonoid contents were estimated via colorimetric and high-performance liquid chromatography (HPLC) methods. Different doses (250, 500 and 750 mg/kg) of mDMF were used to evaluate the anti-inflammatory and anti-arthritis actions in acute inflammatory (carrageenan and histamine-induced paw oedema) and Freund's complete adjuvant (FCA)-induced arthritis rat models. Levels of various pro- and anti-inflammatory biomarkers were estimated using ELISA and RT-PCR techniques. Paw samples were used for different histopathological and radiographic studies. Qualitative phytochemical and HPLC analyses indicated the presence of various polyphenolic compounds in mDMF, which exhibited marked antioxidant activity in the DPPH assay. mDMF showed time-dependent anti-inflammatory and anti-arthritic effects in in vivo models. ELISA assay data showed significant (p < 0.05) reduction in the serum levels of C-reactive protein and rheumatoid factor in the mDMF treatment groups. RT-PCR data showed significant (p < 0.05) down-regulation of various pro-inflammatory markers (TNF-α, NF-κB, COX-2, IL-1β and IL-6) and up-regulation of anti-inflammatory markers (IκB, IL-4 and IL-10) in serum samples of rats treated with mDMF. The histopathology of the ankle joints showed reduced pannus formation, joint swelling and synovial hyperplasia in mDMF-treated animals when compared with the untreated disease control group. Overall, it may be concluded that the antioxidant, anti-inflammatory and anti-arthritis properties of mDMF are due to its flavonoid and phenolic constituents. Further studies using a stable oral dosage form of D. malabarica (Desr.) Kostel fruits extract are warranted to explore its effects in other inflammatory disorders, including irritable bowel syndrome, appendicitis and hepatitis.

Abstract
The oral delivery of diclofenac sodium (DNa), a non-steroidal analgesic, anti-inflammatory drug, is associated with various gastrointestinal side effects. The aim of the research was to appraise the potential of transdermal delivery of DNa using bilosomes as a vesicular carrier (BSVC) in inflamed paw edema. DNa-BSVCs were elaborated using a thin-film hydration technique and optimized using a 31.22 multilevel categoric design with Design Expert® software 10 software (Stat-Ease, Inc., Minneapolis, MI, USA). The effect of formulation variables on the physicochemical properties of BSVC, as well as the optimal formulation selection, was investigated. The BSVCs were evaluated for various parameters including entrapment efficiency (EE%), vesicle size (VS), zeta potential (ZP) and permeation studies. The optimized BSVC was characterized for in vitro release, Fourier transform infrared spectroscopy (FTIR), transmission electron microscopy (TEM) and incorporated into hydrogel base. The optimized DNa-BSVC gel effectiveness was assessed in vivo using carrageenan-induced paw edema animal model via cyclooxygenase 2 (COX-2), interleukin 6 (IL-6), Hemooxygenase 1 (HO-1) and nuclear factor-erythroid factor2-related factor 2 (Nfr-2) that potentiate anti-inflammatory and anti-oxidant activity coupled with histopathological investigation. The resulting vesicles presented VS from 120.4 ± 0.65 to 780.4 ± 0.99 nm, EE% from 61.7 ± 3.44 to 93.2 ± 2.21%, ZP from −23.8 ± 2.65 to −82.1 ± 12.63 mV and permeation from 582.9 ± 32.14 to 1350.2 ± 45.41 µg/cm2. The optimized BSVCs were nano-scaled spherical vesicles with non-overlapped bands of their constituents in the FTIR. Optimized formulation has superior skin permeability ex vivo approximately 2.5 times greater than DNa solution. Furthermore, histological investigation discovered that the formed BSVC had no skin irritating properties. It was found that DNa-BSVC gel suppressed changes in oxidative inflammatory mediators (COX-2), IL-6 and consequently enhanced Nrf2 and HO-1 levels. Moreover, reduction of percent of paw edema by about three-folds confirmed histopathological alterations. The results revealed that the optimized DNa-BSVC could be a promising transdermal drug delivery system to boost anti-inflammatory efficacy of DNa by enhancing the skin permeation of DNa and suppressing the inflammation of rat paw edema.

Abstract
Infertility is one of the disorders that worries many couples around the world, although novel and molecular methods can be used to cure this disease in different stages. One of the factors that causes infertility in men and women is the increased oxidative stress within the cells, which can lead to damage in zygote formation. ROMO1 is one of the most important proteins in the production of reactive oxygen species. This protein can enhance oxidative stress in the cells and body through cellular pathways, such as TNF-α and NF-κB routes, which will eventually lead to many diseases, especially infertility. We engage several international databases by using keywords; ROMO1, Infertility, and Reactive Oxygen Species, and gained a great quantity of information about ROMO1, Infertility, and Oxidative Stress. Although not proven, it is hypothesized that ROMO1 might elevate oxidative stress by activating NF-κB pathway in the cells, furthermore, TNF-α can arouse ROMO1 that can end up with apoptosis and cell death, which consequently can have a lot of disturbing effects on the body, especially the reproductive system. To sum up, revealing the exact cellular and molecular mechanisms of ROMO1-dependent TNF-α and NF-κB pathways in the pathogenesis of infertility might find interesting therapeutic and management strategies for this disorder.

Abstract
Background: Inflammation is a strong reaction of the non-specific natural immune system that helps to start protective responses against encroaching pathogens and develop typical immunity against intruding factors. However, prolonged inflammation may lead to chronic autoimmune diseases. For thousands of years, medicinal plants have served as an excellent source of treatment for chronic pathologies such as metabolic diseases. Purpose: The present study aims to evaluate the anti-inflammatory and anti-angiogenic potential of Moringa olifera Lam. extract (MO) and Moringa-loaded nanoclay films. Methods: The extract preparation was done through the maceration technique using absolute methanol (99.7%) and labelled as Mo. Me. Mo. Me-loaded nanoclay-based films were prepared by using pectin and sericin (Table 1). The in vitro studies characterized the film thickness, moisture, and phytochemical contents. The in vivo anti-inflammatory tests involved using a cotton pellet-induced granuloma model assay. In addition, the chick chorioallantoic membrane (CAM) assay was employed for angiogenesis activity. Results: The phytochemical analysis of the extract confirmed the presence of alkaloids, glycosides, flavonoids and phytosterol. This extract contained quercetin in a large quantity. Cotton-pellet induced granuloma model study revealed a comparable (p > 0.05) effect of a high dose of Mo. Me (500 mg/kg) as compared with standard drug. Noteworthy, data obtained through the RT-PCR technique manifested the dose-dependent anti-oedematous effect of Moringa olifera via downregulation of TNF-α and interleukin-1ß. The findings of the CAM assay exhibited a remarkable anti-angiogenic activity of Mo. Me loaded nanoclay films, showing diffused vasculature network in the macroscopic snapshot. Conclusion:Moringa olifera and its nanocomposite films have therapeutic potential against inflammation.

Qu J, Zhao Y, Zhang L, Hu S, Liao K, Zhao M, Wu P, Jin H. Evaluated serum perfluoroalkyl acids and their relationships with the incidence of rheumatoid arthritis in the general population in Hangzhou, China. ENVIRONMENTAL POLLUTION (BARKING, ESSEX : 1987) 2022; 307:119505. [PMID: 35605832 DOI: 10.1016/j.envpol.2022.119505] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/03/2021] [Revised: 05/15/2022] [Accepted: 05/16/2022] [Indexed: 06/15/2023]
Abstract
Perfluoroalkyl acids (PFAAs) are widely present in human blood, and have many toxic effects on humans. However, effects of PFAA exposure on the risk of rheumatic immune diseases are limited. In the present study, occurrence of 7 PFAAs, including perfluorooctane sulfonate (PFOS), perfluorooctanoic acid (PFOA), perfluorononanoate (PFNA), perfluorodecanoate (PFDA), perfluoroundecanoate (PFUnA), perfluorododecanoate (PFDoA), and perfluorotrdecanoate (PFTrA), were measured in serum samples from 156 healthy people (controls) and 156 rheumatoid arthritis (RA) cases living in Hangzhou, China. We also investigated the relationships among cumulative PFAA levels in serum, some immune markers, and the incidence of RA. The results showed that PFOA (6.1 and 11.8 ng/mL) had the highest mean serum concentrations, followed by PFOS (3.2 and 3.4 ng/mL) and PFDA (0.86 and 2.6 ng/mL), in both controls and RA cases. Cumulative exposure to PFOA in the study population were positively correlated with the levels of rheumatoid factors (rs = 0.69, p < 0.01) and anti-cyclic citrullinated peptide antibody (rs = 0.56, p < 0.05). Moreover, significant associations of PFOA concentrations with odds ratios (OR) of RA (OR = 1.998, confidence interval (CI): 1.623, 2.361, p = 0.01) were found by adjusting for various covariates. The crude and adjusted OR for RA was respective 1.385 (95% CI: 1.270, 1.510, p = 0.04) and 1.381 (95% CI: 0.972, 1.658, p = 0.06) for a unit increase in serum PFOS levels, but the adjusted results were not significant. Overall, this case-control study found that human serum PFOA concentrations were positively correlated with RF and ACPA levels.

Abstract
Background Thrombosis is a major disorder which is an outcome of an imbalance in the hemostatic system that develop undesirable blood clot and hinder blood circulation. Purpose The current study was designed to verify the potential of aqueous methanolic crude extract of Asphodelus tenuifolius Cav. (At.Cr), used traditionally as remedy in circulatory problems. Research Design Antioxidant activity, FTIR, and HPLC analysis were performed. In-vitro clot lysis assay was performed on human blood samples, and in-vivo acute pulmonary thromboembolism model was developed by administering the mixture of collagen and epinephrine in tail vein of mice. Carrageenan-induced thrombosis and FeCl3-induced carotid arterial thrombosis models were developed in rats. Results At.Cr demonstrated significant increase in lysis of human blood clot. Bleeding and clotting times were increased dose-dependently. Lungs histology showed clear alveolar spaces with decreased red blood cells congestion. Reduction in infarcted tail length, augmentation in prothrombin time, and activated partial thromboplastin time with decrease in platelet count were observed. At.Cr also prolonged the arterial occlusion time and reduced the weight of thrombus and TXB2 levels dose-dependently. Conclusions The results demonstrated the antithrombotic and thrombolytic potential of At.Cr due to activation of coagulation factors through extrinsic and intrinsic pathways.

Shaoyao-Gancao Decoction Promoted Microglia M2 Polarization via the IL-13-Mediated JAK2/STAT6 Pathway to Alleviate Cerebral Ischemia-Reperfusion Injury. Mediators Inflamm 2022; 2022:1707122. [PMID: 35757105 PMCID: PMC9232306 DOI: 10.1155/2022/1707122] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2022] [Accepted: 05/19/2022] [Indexed: 11/17/2022] Open
Abstract
Microglia in the penumbra shifted from M2 to M1 phenotype between 3 and 5 days after cerebral ischemia-reperfusion, which promoted local inflammation and injury. Shaoyao-Gancao Decoction (SGD) has been found to result in a significant upregulation of IL-13 in the penumbra, which has been shown to induce polarization of M2 microglia. There was thus a hypothesis that SGD could exert an anti-inflammatory and neuroprotective effect by activating IL-13 to induce microglia polarization towards M2 phenotype, and the purpose of this study was to explore the influence of SGD on microglia phenotype switching and its possible mechanism. Rats who received middle cerebral artery occlusion surgery (MCAO) were treated with SGD for 3 or 6 days, to investigate the therapeutic effect and the underlying mechanism of SGD for cerebral ischemia-reperfusion injury (CI/RP). The results indicated that SGD improved neurobehavioral scores and reduced apoptosis. Furthermore, SGD significantly decreased M1 microglia and M1-like markers, but increased M2 microglia and M2 markers. Moreover, higher levels of IL-13 and ratios of p-JAK2/JAK2 and p-STAT6/STAT6 were found in the SGD group compared to the MCAO. In conclusion, it was verified that SGD prevented injury by driving microglia phenotypic switching from M1 to M2, probably via IL-13 and its downstream JAK2-STAT6 pathway. Given that no further validation tests were included in this study, it is necessary to conduct more experiments to confirm the reliability of the above results.

Abstract
Coronopus didymus (L.) Sm. (CD) has been traditionally used to treat pain, rheumatism, and inflammation. This study was planned to appraise the anti-oxidant, anti-inflammatory and anti-arthritic potentials of CD (whole plant) aqueous ethanolic (CDAEE) and aqueous extracts (CDAE) and chemical characterization by high-performance liquid chromatography-diode array detector. In vivo anti-inflammatory (Carrageenan induced paw edema, and Xylene induced ear edema assays) and anti-arthritic potentials were evaluated in Wistar rats. Both extracts showed significant (p < 0.0001) in vitro free radical scavenging and in vitro anti-arthritic potentials by inhibition of protein denaturation and stabilization of the HRBC membrane and anti-oedematogenic potential, whereas more activity was expressed by CDAEE. In complete Freund's adjuvant-induced arthritic model, the CDAEE at 200, 400, and 800 mg kg-1 and methotrexate (1 mg kg-1) profoundly (p < 0.05) reduced the arthritic score and paw edema, restored body and immune organ weight, and altered blood parameters and oxidative stress biomarkers. The qRT-PCR analysis revealed that CDAEE at 400 mg kg-1 significantly (p < 0.0001) downregulated TNF-α (2.22 ± 0.16 fold), IL-6 (2.29 ± 0.05 fold), IL-1β (2.10 ± 0.01 fold), COX-2 (2.45 ± 0.02 fold), and NF-ĸβ (2.72 ± 0.06 fold) and considerably upregulated IL-10 (58.84 ± 0.67%), IL-4 (76.16 ± 2.79%) and I-kβ (75.45 ± 0.17%) in arthritic rats in contrast to disease control and methotrexate as evidenced from the joint histology. These findings suggested the antioxidant, anti-inflammatory and anti-arthritic activities of C. didymus, which might be due to the presence of quercetin, ferulic acid, dihydromyricetin, apigenin, vitexin, and kaempferol in CDAEE.

Abstract
Cognitive dysfunction is an important complication observed in type 2 diabetes mellitus (T2DM) patients. Tetramethylpyrazine (TMP) is known to exhibit anti-diabetic and neuroprotective properties. Therefore, the present study aimed to investigate the possible therapeutic effects of TMP against type 2 diabetes-associated cognitive impairment in rats. High-fat diet (HFD) followed by a low dose of streptozotocin (35 mg/kg) was used to induce diabetes in Sprague-Dawley rats. TMP (20, 40, and 80 mg/kg) and Pioglitazone (10 mg/kg) were administered for 4 weeks. The Morris water maze (MWM) and novel objective recognition task (NOR) tests were used to assess memory function. Fasting blood glucose (FBG), lipid profile, HOMA-IR, glycosylated hemoglobin (HbA1c), and glucose tolerance were measured. Acetylcholinesterase (AChE) and choline acetytransferase (ChAT) activity, acetylcholine (ACh) levels, oxidative stress, apoptotic (Bcl-2, Bax, caspase-3), and inflammatory markers (TNF-α, IL-1β, and NF-kβ) were assessed. BDNF, p-AKT, and p-CREB levels were also measured. In the present work, we observed that treatment of diabetic rats with TMP alleviated learning and memory deficits, improved insulin sensitivity, and attenuated hyperglycemia and dyslipidemia. Furthermore, treatment with TMP increased BDNF, p-Akt, and p-CREB levels, normalized cholinergic dysfunction, and suppressed oxidative, inflammatory, and apoptotic markers in the hippocampus. Collectively, our results suggest that the TMP may be an effective neuroprotective agent in alleviating type 2 diabetes-associated cognitive deficits.

Abstract
Uncontrolled inflammation plays a central role in the pathogenesis of various diseases. Currently available anti-inflammatory agents on prolonged use may lead to ulcers or thrombus formation. The present study was designed to evaluate the anti-inflammatory, anti-arthritic and anti-angiogenic potentials of methanol extract of Viola betonicifolia using battery of in vivo models. Methanol extract of Viola betonicifolia (Vb.Me) was prepared through maceration. High performance liquid chromatography (HPLC) and gas chromatography mass spectrometery (GC-MS) were performed to identify bioactive compounds present in Vb.Me. In vivo safety profile of Vb.Me was evaluated following OECD 425 acute toxicity guidelines. Anti-inflammatory potential of Vb.Me at three different dose levels was evaluated in in vivo acute (carrageenan and, histamine-induced paw oedema), sub-chronic (cotton pellet-induced granuloma) and chronic (Complete Freund's adjuvant-induced arthritis) models. Blood and paws samples were collected to study effects of Vb.Me treatment on the expression of various pro- and anti-inflammatory genes (RT-PCR) and to study the histopathological changes at tissue levels. Effects of Vb.Me on neovasculature development were studied in ex-ovo chicken chorioallantoic membrane (CAM) assay. Quercetin and n-hexadecanoic were identified as one of the major bioactive molecules in HPLC and GC-MS analysis of Vb.Me. Toxicity data revealed that Vb.Me was safe for administration up to the dose of 2000 mg/kg. Findings of inflammatory models showed that Vb.Me produced time and dose-dependent effects. 500 mg/kg Vb.Me showed significantly (p < 0.05) better effects as compared with 125 and 250 mg/kg. 500 mg/kg Vb.Me also showed comparable anti-inflammatory effects with indomethacin in both acute and chronic models respectively. RT-PCR data exhibited significant (p < 0.05) down-regulation of IL-6, IL-1ß, NF-kß, TNF-α and COX-2 genes with simultaneous up-regulation of IL-4 and IL-10 genes in the blood samples of animals treated with 500 mg/kg of Vb.Me and 10 mg/kg of indomethacin respectively. CAM assay data revealed arrest of microvessel outgrowth in Vb.Me-treated eggs. Altogether, findings of the current study indicate that Vb.Me exerts in vivo anti-inflammatory and anti-angiogenic effects through regulation of expression of various pro- and anti-inflammatory genes. Synergist actions of various bioactive molecules in Vb.Me are proposed to be responsible for these attributes. However, further studies to standardize the extract and evaluation of its potential in various inflammation-induced diseases are warranted.

Abstract
Background: Exercise has been proven to be an effective therapy for stroke by reducing the microglia-initiated proinflammatory response. Few studies, however, have focused on the phenotypic changes in microglia cells caused by exercise training. The present study was designed to evaluate the influence of treadmill exercise on microglia polarization and the molecular mechanisms involved. Methods: Male Sprague-Dawley rats were randomly assigned into 3 groups: sham, MCAO and exercise. The middle cerebral artery occlusion (MCAO) and exercise groups received MCAO surgery and the sham group a sham operation. The exercise group also underwent treadmill exercise after the surgery. These groups were studied after 4 and 7 days to evaluate behavioral performance using a modified neurological severity score (mNSS), and infarct conditions using 2,3,5-triphenyl tetrazolium chloride. Quantitative real-time polymerase chain reaction (qRT-PCR) and Luminex was employed to determine the expressions of markers of microglia phenotypes. Western blotting was employed to identify the phosphorylation levels of Janus kinase1 (JAK1) and signal transducer and activator of transcription 6 (STAT6). Immunofluorescence was conducted to identify microglia phenotypes. Results: Treadmill exercise was found to improve neurobehavioral outcomes, mainly motor and balance functions, reduce infarct volumes and significantly increase interleukin-4 (IL-4) expression. In addition, treadmill exercise inhibited M1 microglia and promoted M2 microglia activation as evidenced by decreased M1 and increased M2 markers. Furthermore, an obvious increase in p-JAK1 and p-STAT6 was observed in the exercise group. Conclusions: Treadmill exercise ameliorates cerebral ischemia-reperfusion injury by enhancing IL-4 expression to promote M2 microglia polarization, possibly via the JAK1-STAT6 pathway.
