Abstract. Revianti S, Andriani D, Parisihni K, Wahjuningsih E, Widyastuti. 2020. Effectiveness of oral irrigation with an extract of green microalga Nannochloropsis oculata as an anti-inflammatory in rats infected with Aggregatibacter actinomycetemcomitans. Biodiversitas 21: 2977-2981. Aggressive periodontitis is strongly correlated with Aggregatibacter actinomycetemcomitans, a periodontopathic bacterium, which releases endotoxins and lipopolysaccharides (LPS). LPS acts as a stimulus to a variety of host cells that can promote the expression of pro-inflammatory cytokines, such as the tumor necrosis factor-α (TNF-α), in periodontal disease. The marine green microalga Nannochloropsis oculata has anti-inflammatory properties. This study aimed to examine the anti-inflammatory efficacy of oral irrigation with N. oculata extract against periodontitis induced by A. actinomycetemcomitans in a rat model. Twenty-four male Wistar rats were divided randomly into four groups (n = 6). First control group was without any treatment, the second to fourth groups were infected with A. actinomycetemcomitans and then orally irrigated with N. oculata extract at concentrations of 2.375%, 2.5%, and 2.625%. The mandibles of the euthanized rats were hemisected to measure the expression of TNF-α, interleukin-10 (IL-10, an anti-inflammatory cytokine), and osteoprotegerin (OPG) by immunohistochemistry. The first group (control) showed significantly higher expression of TNF-α and significantly lower expression of IL-10 and OPG compared to the other groups. Oral irrigation with N. oculata extracts reduced the expression of TNF-α and enhanced the expression of IL-10 and OPG in rats infected with A. actinomycetemcomitans. The effective concentration of N. oculata extract as an anti-inflammatory for oral irrigation was 2.375%.

Background: Bacteria playing a role in periodontitis are Gram-negative anaerobic bacteria that can release endotoxin or lipopolysaccharide (LPS). LPS acts as a stimulus to a variety of host cells that can stimulate expression of pro-inflammatory cytokines in periodontal disease, such as IL-1α, IL-1β, and TNF-α. Increased TNF-α then can lead to periodontal tissue destruction. Furthermore, cassava leaves have many health benefits due to flavonoid organic compound contained, known to possess anti-inflammatory activity are used as a medicine. Purpose: This study aimed to determine the effect of cassava leaf flavonoid extract as a basic ingredient of anti-inflammatory gel on TNF-α expression in Wistar rats suffering from periodontitis induced with Escherichia coli (E. coli) LPS. Method: This study used 24 male Wistar rats. Those rats were divided into six groups. Group 1 consisted of four rats induced with E. coli LPS for 2 weeks, and then decapitation was performed on day 3. Group 2 consisted of four rats induced with E. coli LPS for 2 weeks, and then decapitation was conducted on day 7. Group 3 consisted of four rats induced with E. coli LPS for 2 weeks, treated with the topical cassava leaf flavonoid extract gel (Manihot esculenta) at a concentration of 25%, and then decapitation was performed on day 3. Group 4 consisted of four rats induced with E. coli LPS for 2 weeks, treated with the topical cassava leaf flavonoid extract gel (Manihot esculenta) at a concentration of 25%, and then decapitation was conducted on day 7. Group 5 consisted of four rats induced with E. coli LPS for 2 weeks, treated with the topical cassava leaf flavonoid extract gel (Manihot esculenta) at a concentration of 50%, and then decapitation was performed on day 3. And, group 6 consisted of four rats induced with E. coli LPS for 2 weeks, treated with the topical Cassava leaf flavonoid extract gel (Manihot esculenta) at a concentration of 50%, and then decapitation was conducted on day 7. The topical Cassava leaf flavonoid extract gel was inserted into gingival sulcus on the first right molar of their lower jaw by using a blunted syringe needle. The gel was given two times a day for 7 days. Result: The expression of TNF-α in the control group was more than that in the treatment groups given the Cassava leaf flavonoid extract gel at the concentrations of 25% and 50%. The expression of TNF-α in the treatment groups given the cassava leaf flavonoid extract gel at the concentration of 50% was lower than that in the treatment groups given the cassava leaf flavonoid extract gel at the concentration of 25%. Conclusion: Cassava leaf flavonoid extract gel could be used as an anti-inflammatory gel characterized by a decrease in TNF-α expression in rat models suffering from periodontitis.

Background: There are close links between chemotherapy-induced intestinal mucositis and microbiota dysbiosis. Previous studies indicated that D-methionine was an excellent candidate for a chemopreventive agent. Here, we investigated the effects of D-methionine on cisplatin-induced mucositis. Materials and methods: Male Wistar rats (176–200 g, 6 weeks old) were given cisplatin (5 mg/kg) and treated with D-methionine (300 mg/kg). Histopathological, digestive enzymes activity, oxidative/antioxidant status, proinflammatory/anti-inflammatory cytokines in intestinal tissues were measured. Next-generation sequencing technologies were also performed to investigate the gut microbial ecology. Results: D-methionine administration increased villus length and crypt depth and improved digestive enzyme (leucine aminopeptidase, sucrose and alkaline phosphatase) activities in the brush-border membrane of cisplatin-treated rats ( p < 0.05). Furthermore, D-methionine significantly attenuated oxidative stress and inflammatory reaction and increased interleukin-10 levels in cisplatin-induced intestinal mucositis ( p < 0.05). Cisplatin administration resulted in high relative abundances of Deferribacteres and Proteobacteria and a low diversity of the microbiota when compared with control groups, D-methionine only and cisplatin plus D-methionine. Cisplatin markedly increased comparative abundances of Bacteroides caccae, Escherichia coli, Mucispirillum schaedleri, Bacteroides uniformis and Desulfovibrio C21-c20, while Lactobacillus was almost completely depleted, compared with the control group. There were higher abundances of Lactobacillus, Lachnospiraceae, and Clostridium butyrium in cisplatin plus D-methionine rats than in cisplatin rats. D-methionine treatment alone significantly increased the number of Lactobacillus reuteri. Conclusion: D-methionine protects against cisplatin-induced intestinal damage through antioxidative and anti-inflammatory effects. By enhancing growth of beneficial bacteria (Lachnospiraceae and Lactobacillus), D-methionine attenuates gut microbiome imbalance caused by cisplatin and maintains gut homeostasis.

Currently the TRPV1 (transient receptor potential vanilloid type 1) channel is considered to be one of the main targets for pro-inflammatory mediators including TNF-α. Similarly, the inhibition of TRPV1 activity in the peripheral nervous system affects pro-inflammatory mediator production and enhances analgesia in total. In this study, the analgesic and anti-inflammatory effects of HCRG21, the first peptide blocker of TRPV1, were demonstrated in a mice model of carrageenan-induced paw edema. HCRG21 in doses of 0.1 and 1 mg/kg inhibited edema formation compared to the control, demonstrated complete edema disappearance in 24 h in a dose of 1 mg/kg, and effectively reduced the productionof TNF-α in both doses examined. ELISA analysis of blood taken 24 h after carrageenan administration showed a dramatic cytokine value decrease to 25 pg/mL by HCRG21 versus 100 pg/mL in the negative control group, which was less than the TNF-α level in the intact group (40 pg/mL). The HCRG21 demonstrated potent analgesic effects on the models of mechanical and thermal hyperalgesia in carrageenan-induced paw edema. The HCRG21 relief effect was comparable to that of indomethacin taken orally in a dose of 5 mg/kg, but was superior to this nonsteroidal anti-inflammatory drug (NSAID) in duration (which lasted 24 h) in the mechanical sensitivity experiment. The results confirm the existence of a close relationship between TRPV1 activity and TNF-α production once again, and prove the superior pharmacological potential of TRPV1 blockers and the HCRG21 peptide in particular.

ObjectivesRecent studies suggested that upregulation of anti-inflammatory immune response during early syphilis may be associated with persistence of Treponema pallidum infection despite adequate treatment, resulting in a serofast state. The objective of this study was to determine whether enhanced interleukin (IL)-10-related response during early T. pallidum infection increased the risk of serofast syphilis.MethodsTwo IL10 gene promoter polymorphisms affecting IL-10 production (−1082A>G [rs1800896], −592C>A [rs1800872]) and serum levels of IL-10 were measured in 80 patients with early syphilis before and 6 months after penicillin treatment and in 24 healthy volunteers (control group).ResultsAfter 6 months, patients were stratified based on serological response into two groups: (1) serofast state (n = 28) and (2) serologically cured (n = 52). Pretreatment and post-treatment serum IL-10 levels were significantly higher in patients who remained serofast compared with those who had a serological cure (p<0.001). The GG genotype of the −1082A>G (rs1800896) polymorphism and the CC genotype of the −592C>A (rs1800872) polymorphism were significantly correlated with higher serum IL-10 levels. Moreover, the OR for remaining serofast for carriers of these genotypes was 16.2 (95% CI: 4.1 to 65.0, p<0.0001) and 2.9 (95% CI: 1.4 to 5.9, p=0.002), respectively.ConclusionsWe showed that a pronounced anti-inflammatory immune response may be an important predictor for the serofast state. Additionally, host-related factors such as polymorphisms of immune regulatory genes may influence the risk of remaining serofast after syphilis therapy.

The Gram-negative bacterium, Aggregatibacter actinomycetemcomitans, has been associated with localized aggressive periodontitis (LAP). In particular, highly leukotoxic strains of A. actinomycetemcomitans have been more closely associated with this disease, suggesting that LtxA is a key virulence factor for A. actinomycetemcomitans. LtxA is secreted across both the inner and outer membranes via the Type I secretion system, but has also been found to be enriched within outer membrane vesicles (OMVs), derived from the bacterial outer membrane. We have characterized the association of LtxA with OMVs produced by the highly leukotoxic strain, JP2, and investigated the interaction of these OMVs with host cells to understand how LtxA is delivered to host cells in this OMV-associated form. Our results demonstrated that a significant fraction of the secreted LtxA exists in an OMV-associated form. Furthermore, we have discovered that in this OMV-associated form, the toxin is trafficked to host cells by a cholesterol- and receptor-independent mechanism in contrast to the mechanism by which free LtxA is delivered. Because OMV-associated toxin is trafficked to host cells in an entirely different manner than free toxin, this study highlights the importance of studying both free and OMV-associated forms of LtxA to understand A. actinomycetemcomitans virulence.

Diphenyl diselenide ((PhSe)2) is a organoselenium compound with potent antioxidant properties. Therefore, the aim of the present study was to evaluate whether subcutaneous supplementation of (PhSe)2 in dairy sheep has positive effects on milk composition, as well as on the prevention of oxidative stress and exacerbated inflammatory response. For this, 16 primiparous recently calved sheep were divided into the following two groups, with eight animals in each: Group A, the control group; and Group B, the group subcutaneously supplemented with five doses of (PhSe)2 of 3.0µmol/kg each every 7 days. Blood samples from supplemented animals showed increased concentration of antioxidant enzymes (catalase, superoxide dismutase, glutathione peroxidase and glutathione-S-transferase), and reduced reactive oxygen species and lipid peroxidation, which prevented oxidative damage in the lactation period, as well as increased seric interleukin-10, an anti-inflammatory cytokine. In the sera, supplemented animals showed increased total antioxidant capacity and ferric-reducing ability of plasma compared with the control group. As a consequence, supplemented animals showed increased antioxidant variables, as well as reduced protein oxidation in milk samples. Moreover, milk from supplemented sheep showed a higher fat content, and lower total protein and lactose contents in some periods in the study, than did not-supplemented ewes. Seric concentrations of interleukin-1 were lower on Days 30 and 45 in supplemented animals, as well as the concentrations of tumour necrosis factor α in all periods, than were those in the control group, whereas the interleukin-10 concentrations were higher. Thus, dairy sheep supplementation of (PhSe)2 activated antioxidant and anti-inflammatory responses, and increased milk fat content. Moreover, this protocol increased the antioxidant and, consequently, reduced the oxidant concentration in milk, which is desirable for product quality.

The advantage in response of Th2 over Th1 is observed in normal pregnancy in peripheral blood. A disturbance of this balance can lead to symptoms of miscarriage and pregnancy loss. The aim of this study was to evaluate the pro- and anti-inflammatory cytokines in sera of women who were diagnosed with missed miscarriage in the first trimester and to compare this systemic immune response to the response in women with normal pregnancy. The study group consisted of 61 patients diagnosed with missed miscarriage. In total, 19 healthy women with uncomplicated first trimester created the control group. Cytokines were determined in the maternal serum by ELISA. The analysis included INF-γ, TNF-α, Il-1β, Il-4, Il-5, Il-6, Il-9, Il-10, Il-13 and TGF-β1. Th1 cytokine levels in the study group reached slightly higher values for INF-γ, Il-1β and slightly lower for IL-6 and TNF-α. In turn, Th2 cytokine levels in the study group were slightly higher (Il-9, Il-13), significantly higher (Il4, p = 0.015; Il-5, p = 0.0003) or showed no differences with the control group (Il-10). Slightly lower concentration involved only TGF-β1. Analysis of the correlation between levels of pro- and anti-inflammatory cytokines resulted in some discrepancies, without showing predominance of a specific immune response. The results did not confirm that women with missed miscarriage had an advantage in any type of immune response in comparison to women with normal pregnancy.

BACKGROUND: Immunological mechanisms of infertility are still poorly understood and controversial, both the cause and treatment. Inflammation, immunology, cell proliferation, cell differentiation, and cell survival are influenced by several proteins, including nuclear factor kappa-B (NFĸB), tumor necrosis factor-α (TNF-α), and interleukin-10 (IL-10). AIM: This study aimed to explore the potential of nano curcumin to prevent anti-sperm antibodies (ASA) formation due to the testes’ inflammatory process in Wistar rats. METHODS: This research is an experimental study with a pre-post-test approach with control group. The research subjects were rats (Rattus norvegicus) of the Wistar strain. The induced animals were grouped into three groups: Group 1 received nano curcumin 1 × 80 mg/kg BW orally, Group 2 received dexamethasone 1 × 0.3 mg/kg BW, and Group 3 received placebo aquadest 1 × 1 mL orally. TNF-α, NF-kB, and IL10 levels in serum were examined with enzyme-linked immunosorbent assay. RESULTS: The nano curcumin treatment showed the ability to reduce the pro-inflammatory cytokine protein TNF-α expression (47.3 ± 2.32) more optimally than dexamethasone treatment (54.4 ± 3.22). Nano curcumin has also shown the ability to reduce the pro-inflammatory cytokine transcription factor, NF-kB (32.5 ± 2.76) more optimally than treatment with dexamethasone (44.6 ± 2.43). CONCLUSION: Nano curcumin can prevent the formation of ASA in testicular trauma through inhibition of the inflammatory response.

Macrophages have been shown to be an important contributor to the pathogenesis of hypertension and stroke. The angiotensin AT2 receptor (AT2R), which is expressed in macrophages, is known to promote vasodialation, natriuresis and lower inflammation. The goal of the present study was to explore the anti-inflammatory role of AT2R stimulation in human macrophage-like THP-1 cells activated by lipopolysaccharide (LPS). Phorbol 12-myristate 13-acetate (PMA) differentiated macrophage-like THP-1 cells were treated with AT2R agonist C21 (1 μmol/L) for 30 minutes prior to activation with LPS (1 μg/ml). Media and cells were collected after 24 hours and were analyzed for levels of pro- and anti-inflammatory cytokines and proteins. Pre-treatment with C21 resulted in a 4-fold increase (104.8±6.1 vs 406.7±52.3) in anti-inflammatory interleukin-10 (IL-10) production and a 5-fold decrease (3560±237 vs 588.8±15.94) in pro-inflammatory tumor necrosis factor-α (TNF-α) levels in the media in response to LPS. Predictably, LPS resulted in a 6-fold up-regulation of iNOS expression which was prevented with C21 pre-treatment. A modest decrease in the anti-inflammatory macrophage mannose receptor C type 2 (MRC2) expression was detected with LPS treatment. AT2R agonist pre-treatment, however, increased this receptor expression by ~70% after LPS activation. C21 alone also resulted in a 20% increase in MRC2 expression compared to untreated controls. The anti-inflammatory effect of AT2R activation was abolished in the presence of neutralizing IL-10 antibody (1 μg/ml), indicating a central role for IL-10 in mediating the beneficial response to C21 in LPS activated macrophages. Further, inhibition of nitric oxide (NO) by L-NAME prior to C21 pre-treatment also prevented the decrease in TNF-α and increase in IL-10 in response to AT2R agonist, which suggests that the anti-inflammatory response to C21 may be mediated via increase in NO production prior to LPS activation of macrophages. In conclusion, AT2R stimulation may potentially suppress the inflammatory response of macrophages to LPS by shifting the balance from pro- to anti-inflammatory cytokine production and may prove to be beneficial in the control of the inflammatory component of stroke and hypertension.
