Carpesium macrocephalum (CM) Fr. et Sav. (Compositae) has been used in Chinese folk medicine as an analgesic, hemostatic, antipyretic, and to suppress inflammatory conditions. In the present study we aimed to provide scientific evidence for the anti-inflammatory properties of CM extract and evaluate the intrinsic mechanisms involved in both in vitro and in vivo experimental models. In in vitro findings, CM significantly inhibited the LPS-stimulated release of proinflammatory mediators such as nitric oxide, tumor necrosis factor-alpha, prostaglandin E2, and interleukin-6 in RAW264.7 macrophages in a concentration-dependent fashion. The attenuation of inflammatory responses in LPS-activated RAW264.7 cells by CM was closely associated with the suppression of nuclear factor-kappa B (NF-κB) phosphorylation, IκB-α degradation, and phosphorylation of Akt. CM treatment also attenuated the phosphorylation of STAT through TRIF dependent pathways in LPS-activated RAW264.7 cells. In vivo studies revealed that CM extract concentration dependently suppressed the acetic acid-induced vascular permeability in mice. Considering the data obtained regulation of multiple signaling mechanisms involving TRIF and Akt/NF-κB pathways might be responsible for the potent anti-inflammatory action of CM, substantiating its traditional use in inflammatory diseases.

Plant-extracted triterpenoids belong to a class of bioactive compounds with pleotropic functions, including antioxidant, anti-cancer, and anti-inflammatory effects. In this work, we investigated the anti-inflammatory and anti-oxidative activities of a semisynthetic derivative of 18βH-glycyrrhetinic acid (18βH-GA), soloxolone methyl (methyl 2-cyano-3,12-dioxo-18βH-olean-9(11),1(2)-dien-30-oate, or SM) in vitro on lipopolysaccharide (LPS)-stimulated RAW264.7 macrophages and in vivo in models of acute inflammation: LPS-induced endotoxemia and carrageenan-induced peritonitis. SM used at non-cytotoxic concentrations was found to attenuate the production of reactive oxygen species and nitric oxide (II) and increase the level of reduced glutathione production by LPS-stimulated RAW264.7 cells. Moreover, SM strongly suppressed the phagocytic and migration activity of activated macrophages. These effects were found to be associated with the stimulation of heme oxigenase-1 (HO-1) expression, as well as with the inhibition of nuclear factor-κB (NF-κB) and Akt phosphorylation. Surprisingly, it was found that SM significantly enhanced LPS-induced expression of the pro-inflammatory cytokines interleukin-6 (IL-6), tumour necrosis factor-α (TNF-α), and interleukin-1β (IL-1β) in RAW264.7 cells via activation of the c-Jun/Toll-like receptor 4 (TLR4) signaling axis. In vivo pre-exposure treatment with SM effectively inhibited the development of carrageenan-induced acute inflammation in the peritoneal cavity, but it did not improve LPS-induced inflammation in the endotoxemia model.

ABSTRACTNeisseria meningitidiscolonizes the nasopharyngeal mucosa of healthy populations asymptomatically, although the bacterial surface is rich in motifs that activate the host innate immunity. What determines the tolerant host response to this bacterium in asymptomatic carriers is poorly understood. We demonstrated that the conserved meningococcal surface protein NhhA orchestrates monocyte (Mo) differentiation specifically into macrophage-like cells with a CD200Rhiphenotype (NhhA-Mφ). In response to meningococcal stimulation, NhhA-Mφ failed to produce proinflammatory mediators. Instead, they upregulated interleukin-10 (IL-10) and Th2/regulatory T cell (Treg)-attracting chemokines, such as CCL17, CCL18, and CCL22. Moreover, NhhA-Mφ were highly efficient in eliminating bacteria. Thein vivovalidity of these findings was corroborated using a murine model challenged withN. meningitidissystematically or intranasally. The NhhA-modulated immune response protected mice from septic shock; Mo/Mφ depletion abolished this protective effect. Intranasal administration of NhhA induced an anti-inflammatory response, which was associated withN. meningitidispersistence at the nasopharynx.In vitrostudies demonstrated that NhhA-triggered Mo differentiation occurred upon engaged Toll-like receptor 1 (TLR1)/TLR2 signaling and extracellular signal-regulated kinase (ERK) and Jun N-terminal protein kinase (JNK) activation and required endogenously produced IL-10 and tumor necrosis factor alpha (TNF-α). Our findings reveal a strategy that might be adopted byN. meningitidisto maintain asymptomatic nasopharyngeal colonization.IMPORTANCENeisseria meningitidisis an opportunistic human-specific pathogen that colonizes the nasopharyngeal mucosa asymptomatically in approximately 10% of individuals. Very little is known about how this bacterium evades immune activation during the carriage stage. Here, we observed thatN. meningitidis, via the conserved surface protein NhhA, skewed monocyte differentiation into macrophages with a CD200Rhiphenotype. Bothin vivoandin vitrodata demonstrated that these macrophages, upon meningococcal infection, played an important role in forming a homeostatic immune microenvironment through their capacity to eliminate invading bacteria and to generate anti-inflammatory mediators. This work provides novel insight into the mechanisms underlying the commensal persistence ofN. meningitidis.

Alverine, a smooth muscle relaxant, is used to relieve cramps or spasms of the stomach and intestine. Although the effects of alverine on spontaneous and induced contractile activity are well known, its anti-inflammatory activity has not been fully evaluated. In this study, we investigated the anti-inflammatory effects of alverine in vitro and in vivo. The production of nitric oxide (NO) in RAW264.7 cells activated by lipopolysaccharide (LPS) or polyinosinic:polycytidylic acid (poly (I:C)) was reduced by alverine. The mRNA expression of inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), and tumor necrosis factor-α (TNF-α) was also dose-dependently inhibited by treatment with alverine. In reporter gene assays, alverine clearly decreased luciferase activity, mediated by the transcription factor nuclear factor κB (NF-κB) in TIR-domain-containing adapter-inducing interferon-β (TRIF)- or MyD88-overexpressing HEK293 cells. Additionally, phosphorylation of NF-κB subunits and upstream signaling molecules, including p65, p50, AKT, IκBα, and Src was downregulated by 200 μM of alverine in LPS-treated RAW264.7 cells. Using immunoblotting and cellular thermal shift assays (CETSAs), Src was identified as the target of alverine in its anti-inflammatory response. In addition, HCl/EtOH-stimulated gastric ulcers in mice were ameliorated by alverine at doses of 100 and 200 mg/kg. In conclusion, alverine reduced inflammatory responses by targeting Src in the NF-κB pathway, and these findings provide new insights into the development of anti-inflammatory drugs.

Several Cissus species have been used and reported to possess medicinal benefits. However, the anti-inflammatory mechanisms of Cissus subtetragona have not been described. In this study, we examined the potential anti-inflammatory effects of C. subtetragona ethanol extract (Cs-EE) in vitro and in vivo, and investigated its molecular mechanism as well as its flavonoid content. Lipopolysaccharide (LPS)-induced macrophage-like RAW264.7 cells and primary macrophages as well as LPS-induced acute lung injury (ALI) and HCl/EtOH-induced acute gastritis mouse models were utilized. Luciferase assays, immunoblotting analyses, overexpression strategies, and cellular thermal shift assay (CETSA) were performed to identify the molecular mechanisms and targets of Cs-EE. Cs-EE concentration-dependently reduced the secretion of NO and PGE2, inhibited the expression of inflammation-related cytokines in LPS-induced RAW264.7 cells, and decreased NF-κB- and AP-1-luciferase activity. Subsequently, we determined that Cs-EE decreased the phosphorylation events of NF-κB and AP-1 pathways. Cs-EE treatment also significantly ameliorated the inflammatory symptoms of HCl/EtOH-induced acute gastritis and LPS-induced ALI mouse models. Overexpression of HA-Src and HA-TAK1 along with CETSA experiments validated that inhibited inflammatory responses are the outcome of attenuation of Src and TAK1 activation. Taken together, these findings suggest that Cs-EE could be utilized as an anti-inflammatory remedy especially targeting against gastritis and acute lung injury by attenuating the activities of Src and TAK1.

Celtis choseniana is the traditional plant used at Korea as a herbal medicine to ameliorate inflammatory responses. Although Celtis choseniana has been traditionally used as a herbal medicine at Korea, no systemic research has been conducted on its anti-inflammatory activity. Therefore, the present study explored an anti-inflammatory effect and its underlying molecular mechanism using Celtis choseniana methanol extract (Cc-ME) in macrophage-mediated inflammatory responses. In vitro anti-inflammatory activity of Cc-ME was evaluated using RAW264.7 cells and peritoneal macrophages stimulated by lipopolysaccharide (LPS), pam3CSK4 (Pam3), or poly(I:C). In vivo anti-inflammatory activity of Cc-ME was investigated using acute inflammatory disease mouse models, such as LPS-induced peritonitis and HCl/EtOH-induced gastritis. The molecular mechanism of Cc-ME-mediated anti-inflammatory activity was examined by Western blot analysis and immunoprecipitation using whole cell and nuclear fraction prepared from the LPS-stimulated RAW264.7 cells and HEK293 cells. Cc-ME inhibited NO production and mRNA expression of inducible nitric oxide synthase (iNOS), cyclooxygenase (COX-2), and tumor necrosis factor-alpha (TNF-α) in the RAW264.7 cells and peritoneal macrophages induced by LPS, pam3, or poly(I:C) without cytotoxicity. High-performance liquid chromatography (HPLC) analysis showed that Cc-ME contained anti-inflammatory flavonoids quercetin, luteolin, and kaempferol. Among those, the content of luteolin, which showed an inhibitory effect on NO production, was highest. Cc-ME suppressed the NF-κB signaling pathway by targeting Src and interrupting molecular interactions between Src and p85, its downstream kinase. Moreover, Cc-ME ameliorated the morphological finding of peritonitis and gastritis in the mouse disease models. Therefore, these results suggest that Cc-ME exerted in vitro and in vivo anti-inflammatory activity in LPS-stimulated macrophages and mouse models of acute inflammatory diseases. This anti-inflammatory activity of Cc-ME was dominantly mediated by targeting Src in NF-κB signaling pathway during macrophage-mediated inflammatory responses.

Rosanortriterpenes A–B (RTA and RTB), two nortriterpenoids, are characteristic constituents in the fruits of Rosa laevigata var. leiocapus. However, pharmacological studies on these compounds are still scarce. In the present study, we aim to investigate the anti-inflammatory mechanisms associated with the effects of RTA–B in RAW264.7 macrophages and LO2 cells by detecting cell viabilities, nitric oxide (NO) production, tumour necrosis factor-alpha (TNF-α), and interleukin-6 (IL-6) production. Simultaneously, the anti-inflammatory action mechanisms of these two compounds were illustrated through western blot assay. Besides, the antihepatic fibrosis activities of these compounds have also been explored. The results demonstrated that RTA and RTB inhibited the production of NO, TNF-α, and IL-6 and suppressed liver fibrosis. RTA and RTB treatment also greatly inhibited the activation of NF-kappaB (NF-κB) pathway. Our study confirmed the promising anti-inflammatory and anti-liver fibrosis actions of RTA–B, suggesting that they might be developed as alternative and promising drugs for the treatment of hepatic inflammatory and fibrotic diseases.

Abstract Objectives Obese adipose tissue (AT) is characterized by decreased fatty acid oxidation (FAO) and overexpression of tumor necrosis factor alpha (TNFα), a potent proinflammatory mediator of AT dysfunction and metabolic diseases. Several studies have shown that biosynthesis of retinoic acid (RA) from retinol (vitamin A) is suppressed in obese AT. RA has been identified as an agonist for peroxisome proliferator-activated receptor beta/delta (PPARβ/δ), a critical inducer of FAO. The present study aimed to identify a potential mediator of suppressing RA synthesis and thus metabolic dysregulation by (1) evaluating the role of TNFa in tissue RA synthesis and metabolism in vivo and (2) investigating the potential roles of all trans-RA (ATRA) against TNFa-induced AT dysfunction in vitro. We hypothesized that altered retinoid metabolism in obese AT leads to AT dysfunction by reducing PPARβ/δ expression in adipocytes and macrophages. Methods Wild-type (WT) or TNFa knockout (KO) mice were fed a high-fat diet (HFD) or a low-fat diet (LFD) for 16 weeks. Selected serum biochemical parameters as well as expression of genes related to FAO and retinol metabolism were assessed by qPCR and Western Blot analysis. 3T3-L1 adipocytes and RAW264.7 macrophages were also employed to evaluate the effect of TNFa and ATRA on RA synthesis and pro-inflammatory responses. Results We found that RA concentration was significantly attenuated in epididymal AT from HFD-fed TNFa KO group concomitant with the upregulation of genes for RA synthesis (RDH10 & RALDH1) and PPARβ/δ compared to HFD-fed WT group. In 3T3-L1 adipocytes, TNFa treatment significantly inhibited RA synthesis from retinol and downregulated the expression of RDH10 & RALDH1 genes and FAO makers (PPARβ/δ protein and CPT1 mRNA). Furthermore, ATRA treatment significantly increased the expression of PPARβ/δ protein and CPT1 mRNA in TNFα-treated cells. In addition, ATRA significantly suppressed adipocyte-conditioned medium-induced inflammatory responses in RAW264.7 macrophages by increasing PPARβ/δ expression. Conclusions These findings suggest that TNFα overexpressed in obesity mediates AT dysfunction by impairing RA synthesis and ATRA may confer protection against obesity-induced metabolic comorbidities.

Plectranthus amboinicus(Lour.) Spreng. is a native Labiatae plant of Taiwan. The plants are commonly used in Chinese folk medicine for the treatment of cough, fever, sore throats, mumps, and mosquito bite. The aim of this study was to investigate the analgesic and antiinflammatory properties of the aqueous extract fromPlectranthus amboinicus(PA)in vivoandin vitro. PA inhibited pain induced by acetic acid and formalin, and inflammation induced by carrageenan. The anti-inflammatory effect of PA was related to modulating antioxidant enzymes' activities in the liver and decreasing the Malondialdehyde (MDA) level and the production of tumor necrosis factor alpha (TNF-α), and cyclooxygenase2 (COX-2) in edema-paw tissue in mice.In vitrostudies show that PA inhibited the proinflammatory mediators in RAW 264.7 cells stimulated with lipopolysaccharide (LPS). PA blocked the degradation of IκB-αand nuclear translocation of NF-κB p65 subunit. Finally, the amount of carvacrol in the aqueous extract of PA was 1.88 mg/g extract. Our findings suggest that PA has analgesic and anti-inflammatory activities. These effects were mediated by inhibiting the proinflammatory mediators through blocking NF-κB activation. Meanwhile, the effects observed in this study provide evidence for folkloric uses ofPlectranthus amboinicus(Lour.) Spreng. in relieving pain and inflammation.

This study aims to investigate the anti-inflammatory responses and mechanisms ofSiegesbeckia orientalisethanol extract (SOE). In cell culture experiments, RAW264.7 cells were pretreated with SOE and stimulated with lipopolysaccharide (LPS) for inflammatory mediators assay. In animal experiments, mice were tube-fed with SOE for 1 week, and s.c. injected withλ-carrageenan or i.p. injected with LPS to simulate inflammation. The degree of paw edema was assessed, and cytokine profile in sera and mouse survival were recorded. Data showed that SOE significantly reduced NO, IL-6, and TNF-α production in LPS-stimulated RAW264.7 cells.In vivostudies demonstrated that mice supplemented with 32 mg SOE/kg BW/day significantly lowered sera IL-6 level and resulted a higher survival rate compared to the control group (P=0.019). Furthermore, SOE inhibited LPS-induced NF-κB activation by blocking the degradation of IκB-α. The SOE also reduced significantly the phosphorylation of ERK1/2, p38, and JNK in a dose-dependent manner. In summary, thein vitroandin vivoevidence indicate that SOE can attenuate acute inflammation by inhibiting inflammatory mediators via suppression of MAPKs- and NF-κB-dependent pathways.

Glycyrrhizic acid (GA) is the main active component of the licorice root, which has been known in traditional medicine since the ancient times. It is a molecule composed of a hydrophilic part, two glucuronic acid molecules, and a hydrophobic part, glycyrrhetinic acid. GA, when subjected to acid hydrolysis, releases 18β- and 18α-glycyrrhetinic acids. Glycyrrhetinic acid is most responsible for the pharmacological activities of licorice. GA has been reported to have multiple therapeutic properties: anti-viral, anti-inflammatory, antitumor, antimicrobial and hepatoprotective. Different approaches have revealed similar anti-inflammatory mechanisms of action of GA, such as the inhibition of translocation of nuclear factor-κB (NF-κB) and suppression of Tumour Necrosis Factor alpha (TNF-α) and interleukins. In this sense, several in vitro and in vivo studies have described the use of GA in the prevention and treatment of several complications, especially microbial/viral infection, and as a novel chemo-preventive agent for liver injury. Recent studies postulated that GA nanoparticles (GANPs) can be a promising strategy for the treatment of Severe Acute Respiratory Syndrome CoronaVirus 2 (SARS-CoV-2) infections. This mini-review summarizes the pharmacological activities of GA and its beneficial effects against various health problems and provides perspectives on the development of versatile nanoplatforms to overcome some limiting physicochemical properties and for enhancing the therapeutic benefits of GA.
