ABSTRACT Job’s tears (coix) is a widely used grain with rich and balanced nutritional value. In this study, a total of 71 metabolites, including amino acid metabolism, sugar metabolism and fatty acid metabolism, were significantly increased in the germinating coix through liquid chromatography tandem mass spectrometry (HPLC-MS/MS). Significant increase in gamma-aminobutyric (GABA) content during seed germination was detected in the metabolites detected. Transcript profiles generated through high-throughput RNA-sequencing data and 2431 differentially expressed genes (DEGs) were identified. The functional of DEGs were also significantly clustered in glucose metabolism and fatty acid metabolism. In the annotation of metabolite variation and differentially expressed genes, 23 regulatory genes and 10 significantly enriched metabolites for GABA content proliferation during coix germination were identified by association analysis. These results provided a theoretical basis for understanding the germination mechanism of coix and promoting its production and application.

ABSTRACT Objective The study was to investigate the possible mechanism of Lu'an GuaPian tea in treating heart failure (HF) via network pharmacology and molecular docking. Method The target of Lu'an GuaPian tea were screened. The GeneCards, NCBI, and DisGeNET databases were searched for HF targets. The GO and KEGG pathway analysis were used to obtain the targets and pathways. Molecular docking was used to verify the most likely targets and flavonoids. Results The Venn diagram revealed that AKT1, TNF, SRC, EGFR, ESR1, PTGS2, MMP9, and KDR were the top 8 target genes. GO and KEGG analysis suggested that Lu'an GuaPian tea could treat HF through PI3K-Akt pathway. Molecular docking predicted that compounds 1 and 7 have the highest binding affinity. Conclusion Lu'an GuaPian tea can be used to treat HF via PI3K-Akt signaling pathway, and the compound 1 and 7 were the most active lead compounds for regulating PI3K.

ABSTRACT The number of Alzheimer’s disease (AD) affected patients is increasing without any effective cure and the etiology remains to be understood. Inflammations, oxidative stress, Aβ, and tauopathy are associated factors of AD. Sodium butyrate (NaB) is an HDAC inhibitor profoundly found to be neuroprotective. We have investigated the neuroprotective effects of NaB in SH-SY5Y cells stimulated with TNF-α/Aβ in SH-SY5Y cells and LPS-induced BV-2 cells. The cell viability and NO production were also investigated by MTT and Griess reagent assay. The expressions of APP/BACE, Aβ, and tau phosphorylation and the apoptotic regulators, including P-53, and caspase-1 were analysed by western blot analysis. Our findings exerted that NaB ameliorated cell death and inhibited NO production in Aβ-induced SH-SY5Y cells and LPS in BV-2 cells. NaB notably decreased the expression of tau hyperphosphorylation in TNF-α-stimulated SH-SY5Y and LPS-induced BV-2 cells. NaB remarkably attenuated APP/BACE and Aβ expressions in TNF-α-induced SH-SY5Y cells. Cell viability was restored by NaB and downregulated apoptotic proteins p-53, caspase-1 level in aggregated Aβ-induced SH-SY5Y cells. NaB increased Nrf-2/HO-1 expressions and substantially reversed the reactive oxygen species in Aβ-induced SH-SY5Y cells. Altogether, our results suggest that NaB could be a potential therapeutic agent against AD. GRAPHICAL ABSTRACT

ABSTRACT Phillyrin is isolated from the fruit of Forsythia suspensa, and exhibits multiple pharmacological effects, including anti-tumor, anti-inflammation, and anti-oxidation activities. Here, we investigated whether phillyrin could alleviate airway hyperresponsiveness (AHR) and eosinophil infiltration in the lungs of asthmatic mice, and mitigate inflammatory responses in tracheal epithelial BEAS-2B cells. IL-4/TNF-α-stimulated BEAS-2B cells were treated with various phillyrin doses. Female BALB/c mice were sensitised and challenged with ovalbumin (OVA), and then treated with intraperitoneal injection different phillyrin doses. In IL-4/TNF-α-stimulated BEAS-2B cells, phillyrin effectively reduced proinflammatory cytokines, chemokines, and eotaxin (CCL11) levels. In the lungs of asthmatic mice, phillyrin treatment relieved AHR, airway inflammation, eosinophil infiltration, and goblet cell hyperplasia. Phillyrin also reduced serum OVA-IgE, and Th2-associated cytokine levels in splenocyte culture medium, and in bronchoalveolar lavage fluid of asthmatic mice. Our results indicate that phillyrin attenuated airway inflammation and eosinophil infiltration in asthmatic mice by suppressing Th2 cytokine production.

ABSTRACT People often simultaneously expose to acceptable/tolerable daily intake of food additives and pesticides in daily life. Exposure in adult rodents to acceptable/tolerable daily intake of food additives and pesticides chemical mixtures (AFACM) is reported to cause health damage. Our recently study reported that AFACM exposure of pregnant mice resulted in neuroinflammation and abnormal emotional behaviours in offspring. Here, we found that neutralising IFN-γ with neutralising antibodies completely blocked the influences induced by maternal AFACM exposure, including the increased IFN-γ level in serum, increased IFN-γ, interleukin-6 and tumour necrosis factor-α levels in prefrontal cortex(PFC) in offspring on postnatal day(PND)7, the abnormal emotional behaviours in offspring on PND56, and the decreased of ATPase phospholipid flippase 8A2(ATP8A2) in the PFC of offspring on PND7. In sum, maternal AFACM exposure induced the PFC neuroinflammation, abnormal emotional behaviours and decreased PFC ATP8A2 expression through increasing systemic IFN-γ in offspring.

ABSTRACT To evaluate the effect of exosomes secreted by berberine-treated bone marrow-derived mesenchymal stem cells (BMSCs) on synovial inflammation in collagen-induced arthritis (CIA) model. Exosomes were isolated from berberine-treated BMSCs (Ber-BMSC-EXs) and untreated BMSCs (BMSC-EXs). CIA rats were developed and treated with Ber-BMSC-EXs or BMSC-EXs. Clinical arthritis index was measured, activation of fibroblast-like synoviocytes (FLSs) were evaluated, and response and frequency of T helper 17 (Th17) and regulatory T (Treg) cells as well as cytokine levels in synovial fluid were determined. Ber-BMSC-EXs (with a superior effect than BMSC-EXs) significantly alleviated RA clinical score and paw inflammation, balanced Th17 and Treg cells’ responses and population, modulated levels of pro-inflammatory and anti-inflammatory cytokines in joint synovial fluid, and inhibited FLS activation in CIA rats. Ber-BMSC-EXs (with a significantly greater effect than BMSC-EXs) could significantly ameliorate synovial joint inflammation and clinical symptoms of arthritis in CIA rats, showing that berberine can reinforce anti-arthritic effects of BMSC-EXs.

ABSTRACT Paeonia lactiflora (P. lactiflora) has been recently reported to increase the production of proinflammatory mediators and activates phagocytosis in macrophages. Thus, in this study, we tried to verify the macrophage activation of Paeoniae Radix Rubra (PRR, also known as red peony root) and elucidate its mechanism of action. PRR upregulated the production of proinflammatory mediators and activated phagocytosis in RAW264.7 cells. However, these effects were reversed by inhibition of TLR2/4. In addition, the inhibition of p38, JNK, and ERK1/2 reduced the PRR-mediated production of proinflammatory mediators, and the SPL-mediated activation of p38, JNK, and ERK1/2 was blocked by the TLR4 inhibition. These findings indicate that PRR may activate macrophages through TLR4-dependent activation of p38, JNK, and ERK1/2. These indicate that PRR has immunostimulatory activity. Thus, it is believed that PRR can be used as a functional food agent that enhances the immune system.

ABSTRACT Vermicompost tea (VCT) is the effluent or leachate with a honey-brown colour collected during vermicomposting, an ecologically significant process essential to today’s organic and regenerative agriculture. Dried earthworm, a.k.a. dilong (DL, meaning “earth dragon”) in traditional Chinese herbal medicine, has long been used as a key component to treat diverse skin diseases, including eczema. In the present study, we hypothesized that VCT might have a positive influence on eczema therapy. It was found that the oral application of 50% VCT in mouse model reduced the ear allergic scores and alleviated the histological changes caused by eczema. Furthermore, the levels of Th2-associated and pro-inflammatory cytokines (namely IL-4 and IL-13 in serum) and IgE (in serum and ear tissues) were significantly reduced by VCT. Therefore, oral administration of 50% VCT exerts immunomodulatory effects on the development of eczema, suggesting its potential as a nutraceutical candidate for eczema treatment. GRAPHICAL ABSTRACT

ABSTRACT Salmonella is a major cause of food poisoning, and its infection and antimicrobial resistance vary regionally due to different sanitary standards and the use of antimicrobials. The aim of this study is to evaluate the microbiological contamination and antimicrobial resistance of Salmonella in Shanghai, providing references for supervision over food safety and clinical treatment. This study analysed the distribution of serotypes, the distribution of antimicrobial resistance in different poultry meats and serotype of Salmonella, the correlation between different antimicrobial resistance, and multiple drug resistance (MDR) of 139 strains of Salmonella from poultry meats. The results showed that the proportion of Salmonella detected in pigeons was high, which could cause severe diseases to humans. The most common resistance was observed to TET (about 60%), and resistance was even found to IPM. Resistance to two or more antimicrobials was accounted for 75.5%, indicating a wide spreading MDR.

ABSTRACT Bovine αS1-casein (αS1-CN) is the main allergen in cow's milk, and immunoglobulin E (IgE) epitopes are the material basis to trigger allergic reactions. Thus, IgE epitopes could be as key targets for precise αS1-CN detection and allergenicity assessment. Here, we designed a tandem containing nine IgE linear epitopes of αS1-CN (tαS1-CN), expressed the recombinant tαS1-CN in Escherichia coli, and prepared the rabbit polyclonal antibody against recombinant tαS1-CN (pAb-tαS1-CN). The obtained recombinant tαS1-CN had a purity of 94.43% and retained the antigenicity and potential allergenicity of IgE epitopes. The pAb-tαS1-CN could recognize the nine IgE epitopes of αS1-CN, and also showed high specificity. The ability of pAb-tαS1-CN to evaluate the potential allergenicity of milk in foods was validated by sera from cow's milk allergy patients. These findings indicate that our prepared pAb-tαS1-CN may represents a valuable tool for the evaluation of milk allergenicity in processed foods.

Thus, IgE epitopes could be as key targets for precise αS1-CN detection and allergenicity assessment. Here, we designed a tandem containing nine IgE linear epitopes of αS1-CN (tαS1-CN), expressed the recombinant tαS1-CN in Escherichia coli, and prepared the rabbit polyclonal antibody against recombinant tαS1-CN (pAb-tαS1-CN). The obtained recombinant tαS1-CN had a purity of 94.43% and retained the antigenicity and potential allergenicity of IgE epitopes. The pAb-tαS1-CN could recognize the nine IgE epitopes of αS1-CN, and also showed high specificity. The ability of pAb-tαS1-CN to evaluate the potential allergenicity of milk in foods was validated by sera from cow's milk allergy patients. These findings indicate that our prepared pAb-tαS1-CN may represents a valuable tool for the evaluation of milk allergenicity in processed foods.","PeriodicalId":12300,"journal":{"name":"Food and Agricultural Immunology","volume":" ","pages":""},"PeriodicalIF":3.0,"publicationDate":"2023-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43287676","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
