Influence of the cell wall on ciprofloxacin susceptibility in selected wild-type Gram-negative and Gram-positive bacteria

The susceptibility of several wild-type bacteria to ciprofloxacin and accumulation of the drug in these bacteria were evaluated. Species studied included Escherichia coli, Serratia marcescens, Pseudomonas aeruginosa, Staphylococcus aureus, Bacillus subtilis and Bacillus cereus. Ciprofloxacin susceptibility was measured for each strain using two different methods: the minimal inhibitory concentration and the bactericidal index. Significant differences were observed between the results derived from these two methods. Whereas the minimal inhibitory concentration was low in all strains tested, ciprofloxacin’s bactericidal activity, as indicated by the bactericidal index, varied with the species studied. To determine whether this finding was due to variations in cell envelope permeability to ciprofloxacin (i.e. to combined cell uptake and efflux), we studied ciprofloxacin accumulation using spectrofluorometry. In Gram-negative bacteria, differences in permeability can lead to altered susceptibility to antibiotics. In fact, the combination of slow uptake and efficient efflux seems to be crucial to the characteristic poor susceptibility of P. aeruginosa to ciprofloxacin. However, the low level of activity of ciprofloxacin against S. aureus and two Bacillus species may have resulted from the drug’s interaction with its target enzymes (i.e. topoisomerase IV in S. aureus and DNA gyrase in Bacillus spp.) rather than diminished permeability.     

The effect of oxidized cholesterol on barrier functions and IL-10 mRNA expression in human intestinal epithelium co-cultured with dendritic cells in the transwell system

The intestinal epithelium is exposed to oxygenated cholesterol products present in foodstuffs. In vitro studies demonstrate the effect of oxysterols on cytokine release by intestinal cells cultured alone. However, physiologically, the response of the intestinal epithelium to external agents occurs in the presence of dendritic cells (DCs). The aim of the study was to analyze the effect of 7-ketocholesterol on the barrier functions and IL-10 mRNA expression of Caco-2 cells in the presence of DCs, and secondly, on IL-10 mRNA expression in DCs. Caco-2 cells were co-cultured with monocyte-derived dendritic cells and induced with 7-ketocholesterol in a transwell system. DCs did not affect the transepithelial electrical resistance (TER) of the Caco-2 cell monolayer, but increased IL-10 mRNA expression in Caco-2 cells. 7-ketocholesterol decreased the TER of Caco-2 cells co-cultured with DCs and diminished IL-10 mRNA expression in Caco-2 cells induced by the presence of DCs. IL-10 mRNA expression fell in DCs co-cultured with Caco-2 cells after treatment with 7-ketocholesterol. Oxidized cholesterols present in gut mucosa may contribute to the decrease of epithelial barrier functions and the inappropriate development of an inflammatory response to food compounds.

Interleukin-17A is involved in development of spontaneous pulmonary emphysema caused by Toll-like receptor 4 mutation

Aim:

To explore the pathogenic role of Th17 cells and interleukin-17A (IL-17A)-associated signaling pathways in spontaneous pulmonary emphysema induced by a Toll-like receptor 4 mutant (TLR4^mut).

Methods:

Lungs were obtained from wild-type (WT) or TLR4mut mice that were treated with or without recombinant mouse IL-17A (1 μg·kg⁻¹·d⁻¹, ip) from the age of 3 weeks to 3 months. Pulmonary emphysema was determined using histology, immunochemistry, and biochemical analysis. T cell polarization was determined with flow cytometry, the levels of cytokines were measured using ELISA, and the levels of IL-17A-associated signaling molecules were detected using Western blot.

Results:

Compared to WT mice, 3 month-old TLR4^mut mice were characterized by significantly reduced infiltration of Th17 cells into lungs (2.49%±1.13 % νs 5.26%±1.39%), and significantly reduced expression levels of IL-17A (3.66±0.99 pg/μg νs 10.67±1.65 pg/μg), IL-23 (12.43±1.28 pg/μg νs 28.71±2.57 pg/μg) and IL-6 (51.82±5.45 pg/μg νs 92.73±10.91 pg/μg) in bronchoalveolar lavage fluid. In addition, p38 MAPK phosphorylation and AP-1 expression were decreased to 27%±9% and 51%±8%, respectively, of that in WT mice. Treatment of TLR4^mut mice with IL-17A increased the infiltration of Th17 cells into lungs and expression levels of IL-17A, IL-6, and IL-23 in bronchoalveolar lavage fluid, attenuated MDA and apoptosis, and improved emphysema accompanied with increased phosphorylation of p38 MAPK and expression of AP-1.

Conclusion:

Th17 cells, in particular the cytokine IL-17A, play a crucial role in the pathogenesis of TLR4^mut-induced spontaneous pulmonary emphysema. Both of them are potential targets for therapeutic strategies for pulmonary emphysema.

Aging effects on the diurnal patterns of gut microbial composition in male and female mice

Composition of the gut microbiota changes with aging and plays an important role in age-associated disease such as metabolic syndrome, cancer, and neurodegeneration. The gut microbiota composition oscillates through the day, and the disruption of their diurnal rhythm results in gut dysbiosis leading to metabolic and immune dysfunctions. It is well documented that circadian rhythm changes with age in several biological functions such as sleep, body temperature, and hormone secretion. However, it is not defined whether the diurnal pattern of gut microbial composition is affected by aging. To evaluate aging effects on the diurnal pattern of the gut microbiome, we evaluated the taxa profiles of cecal contents obtained from young and aged mice of both sexes at daytime and nighttime points by 16S rRNA gene sequencing. At the phylum level, the ratio of Firmicutes to Bacteroidetes and the relative abundances of Verrucomicrobia and Cyanobacteria were increased in aged male mice at night compared with that of young male mice. Meanwhile, the relative abundances of Sutterellaceae, Alloprevotella, Lachnospiraceae UCG-001, and Parasutterella increased in aged female mice at night compared with that of young female mice. The Lachnospiraceae NK4A136 group relative abundance increased in aged mice of both sexes but at opposite time points. These results showed the changes in diurnal patterns of gut microbial composition with aging, which varied depending on the sex of the host. We suggest that disturbed diurnal patterns of the gut microbiome can be a factor for the underlying mechanism of age-associated gut dysbiosis.

Comparative effect of ochratoxin A on inflammation and oxidative stress parameters in gut and kidney of piglets

Ochratoxin A (OTA) is a secondary metabolite produced by fungi of Aspergillus and Penicillium genra. OTA is mainly nephrotoxic but can also cause hepatotoxicity, mutagenicity, teratogenicity, neurotoxicity and immunotoxicity. As recent studies have highlighted the close relationship between gastrointestinal tract and kidney, as principal organs involved in absorption and respective excretion of xenobiotics, the aim of the present study was to analyze the effect of a subchronic exposure (30 days) to 0.05 mg/kg OTA on immune response and oxidative stress parameters at the level of intestine and kidney of young swine. The experiment was realised on twelve crossbred weaned piglets randomly allotted to both control group or toxin group fed 0.050 mg OTA/kg feed. Our results have shown that a subchronic intoxication with a low dose of OTA for 30 days affected the immune response and the anti-oxidant self-defense at gut and kidney level. The gene expression of both markers of signaling pathways involved in inflammation and inflammatory cytokines were affected in a much higher extent in the gut than in the kidney Of OTA intoxicated piglets.

The effect of ciprofloxacin and clarithromycin on sildenafil oral bioavailability in human volunteers

Sildenafil is the first oral therapeutic agent for the management of male erectile dysfunction. Its oral bioavailability is only 40% due to extensive presystemic elimination, mainly by CYP3A4. This study examined the effect of coadministration of ciprofloxacin or clarithromycin, which inhibit CYP3A4, on the bioavailability and pharmacokinetics of sildenafil. Twelve healthy male volunteers received sildenafil alone or after pretreatment with the inhibitors in a balanced three-way crossover design. The pharmacokinetic analysis showed that ciprofloxacin coadministration with sildenafil significantly increased the AUC from 1407 +/- 380 to 2986 +/- 917 microg h/l (90% confidence interval 119%-159%) and the Cmax from 287 +/- 67 to 623 +/- 192 microg/l (90% confidence interval 127%-152%). Similarly, clarithromycin coadministration increased sildenafil AUC from 1407 +/- 380 to 3209 +/- 762 microg h/l (90% confidence interval 127%-161%) and Cmax from 287 +/- 67 to 694 +/- 259 microg/l (90% confidence interval 132%-157%). Ciprofloxacin coadministration and clarithromycin coadministration with sildenafil did not affect the rate of sildenafil absorption significantly. These results indicate that coadministration of ciprofloxacin and clarithromycin significantly increased sildenafil bioavailability which can be attributed to the inhibitory effect of ciprofloxacin and clarithromycin on CYP3A4. Dose adjustment of sildenafil is thus necessary when administered with such drugs.     

The elicitation step of nickel allergy is promoted in mice by microbe-related substances, including some from oral bacteria

Microbial components activate the host's innate immunity via interactions with molecules including TLRs and NODs. We previously reported that in mice (i) Escherichia coli lipopolysaccharide (LPS; TLR4 agonist) promotes Ni-allergy even in T-cell-deficient mice, (ii) E. coli LPS reduces the minimum allergy-inducing concentrations of Ni at both the sensitization and elicitation steps, and (iii) various microbe-related substances promote sensitization to Ni. Here, we examined the effects of microbe-related substances at the elicitation step. Mice (except for TLR4-mutated C3H/HeJ mice) were sensitized to Ni by intraperitoneal injection of NiCl₂ + E. coli LPS. Ten days later their ear-pinnas were challenged with 1 μM NiCl₂ with or without a test substance. Although NiCl₂ alone at this concentration does not induce Ni-allergy, its combination with the following substances induced Ni-allergy in BALB/c mice: LPS preparations from oral Gram-negative bacteria (Prevotella intermedia and Porphyromonas gingivalis), a mannan preparation from a fungus (Saccharomyces cerevisiae), and synthetic NOD2 and TLR2 agonists. The effect of the mannan preparation was small in C3H/HeJ mice (sensitized with NiCl₂ + the P. intermedia preparation). The P. intermedia preparation promoted Ni-allergy in C3H/HeJ and nude mice, but not in mice deficient in either TLR2 or histidine decarboxylase. Intragingival injection of the P. intermedia preparation and later challenge with NiCl₂ alone to ear-pinnas also promoted Ni-allergy. These results indicate that (i) in Ni-allergy, a microbial milieu or innate immunity is important at the elicitation step, too, and (ii) some oral bacteria may promote Ni-allergy via TLR2-stimulant(s) production.

三叶青藤正丁醇部位对DBA/1小鼠胶原性关节炎的作用及机制

目的：观察三叶青藤正丁醇部位（nbuIR）对胶原性关节炎小鼠关节病变及血清炎症因子的抑制作用。方法：用DBA/1小鼠建立胶原性关节炎（CIA）动物模型,将造模成功小鼠随机分为模型对照组、甲氨蝶呤组、nbuIR低、中、高剂量组,另设正常对照组。灌胃给药,给药期间每周进行一次关节炎指数评分。干预结束后,ELISA法检测各组小鼠血清IL-23和IL-17水平,H-E染色观察各组小鼠踝关节组织病理学改变。结果：与模型对照组比较,nbuIR高剂量组血清IL-23和IL-17水平明显降低（P<0.01）,滑膜细胞增生与炎症细胞浸润程度明显减轻。结论：nbuIR能改善CIA小鼠局部关节肿胀,下调血清IL-23和IL-17水平,减少滑膜炎症程度,其机制可能与调节IL-23/IL-17轴有关。     

Impact of dietary ingredients on the interpretation of various fecal parameters in rats fed inulin

In the present study, the influences of diets (i.e. chow and AIN-93 diets) on the interpretation of various fecal parameters including viable microbiota, moisture, weight, and short-chain fatty acids in rats fed different amounts of inulin (0.5–2 g/kg). Eight groups of rats (n = 8/group) were fed, for 4 weeks, chow or AIN-93 diets with or without inulin supplementation. Fecal samples were analyzed for different fecal parameters. After a 2-week adaptation, apparent differences in some fecal parameters were observed between the chow and AIN-93 diet groups. Throughout the 4-week intervention period, significantly (p < 0.05) higher Lactobacillus spp. counts, fecal moisture (∼2.7-fold), and fecal weight (∼5.8-fold) were observed with chow diet over AIN-93 diet. More specifically, significant elevations in the levels of Bifidobacterium spp., Lactobacillus spp., fecal moisture, and fecal weight could be observed at low-dose (0.5 g/kg) of inulin in chow diet groups, while most of these changes could merely be seen at medium-dose (1 g/kg) in AIN-93 diet groups. These results demonstrated that the choice of experimental diets would affect the comparison of fecal parameters as well as the interpretation of effective dosage of prebiotic in intestinal health assessments.

Regulators of endothelial and epithelial barrier integrity and function in acute lung injury

Permeability edema is a life-threatening complication accompanying acute lung injury (ALI), severe pneumonia and the acute respiratory distress syndrome (ARDS), which can be associated with a reduced alveolar liquid clearance (ALC) capacity, a disruption of the alveolar epithelial barrier, and an increased capillary endothelial permeability. Bacterial and viral infections can directly promote pulmonary endothelial hyperpermeability and indirectly decrease the function and/or expression of ion transporters regulating ALC in type II alveolar epithelial cells, by means of inducing a strong inflammatory and oxidative stress response in the infected lungs. Apart from ventilation strategies, no standard treatment exists for permeability edema, making the search for novel regulators of endothelial and epithelial hyperpermeability and dysfunction important. Here, we present an overview of recently identified substances that inhibit and/or reverse endothelial barrier disruption and permeability or alveolar epithelial dysfunction: (1) zinc chelators, which were shown to attenuate the effects of oxidative stress on the pulmonary endothelium; (2) peroxisome proliferator activated receptor (PPAR) ligands, which have been shown to exert anti-inflammatory effects, by decreasing the expression of pro-inflammatory genes; (3) extracellular ATP, produced during inflammation, which induces a rapid and dose-dependent increase in transendothelial electrical resistance (TER) across pulmonary endothelial cells; (4) the lectin-like domain of TNF, which is spatially distinct from the receptor binding sites and which protects from hydrostatic and permeability edema and (5) Hsp90 inhibitors, which prevent and repair toxin-induced hyperpermeability. Unraveling the mechanism of action of these agents could contribute to the development of novel therapeutic strategies to combat permeability edema.
