The analysed protein was the tropomyosin. The results confirmed the presence of the tropomyosin (3.77 ± 0.79–5.75 ± 0.01 µg/g) in control samples. This study demonstrated that the bioactive substances in the form of grape (0.61 ± 0.34–0.43 ± 0.16 µg/g), blueberry (0.58 ± 0.32–0.39 ± 0.27 µg/g), and parsley extracts (2.09 ± 1.28–0.79 ± 0.40 µg/g) reduces immunoreactivity (p < 0.05) of the tropomyosin. The elder pollen had no significant effect (p > 0.05) on immunoreactivity. ZnO and TiO2 nanoparticles also demonstrated immunoreactivity reduction (p < 0.05). The exception was silver nanoparticles, where the immunoreactivity increased with increasing concentration of grape extract (1.29 ± 0.01–5.47 ± 0.25 µg/g). The results confirmed the inhibitory effect of bioactive substances on the immunoreactivity of the used ELISA and also showed the need to consider immunoreactive substances when interpreting ELISA results.","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":"46655133","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}

To understand the molecular role of viridicatol in stabilising mast cells, transcriptomes of viridicatol-treated RBL-2H3 cells were analysed by RNA-sequencing. There were 128 differentially expressed genes in activated RBL-2H3 cells with or without viridicatol treatment. The mast cell activation-related genes were significantly reduced by treatment with viridicatol through RT-qPCR analysis. Moreover, Kyoto Encyclopedia of Genes and Genomes enrichment analysis indicated that viridicatol was important in mast cell stabilisation by affecting MAPK and JAK-STAT signalling pathways. Additionally, molecular docking and western blot analysis revealed that the phosphorylated JNK, ERK, P38, and STAT6 proteins were inhibited by viridicatol. Taken together, viridicatol has the potential to be used as a new type of anti-food allergic functional material via controlling MAPK and JAK-STAT signalling pathways of mast cells.","PeriodicalId":12300,"journal":{"name":"Food and Agricultural Immunology","volume":" ","pages":""},"PeriodicalIF":3.0,"publicationDate":"2023-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41962549","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}

The sampling was conducted between 7 April and 23 October 2019, covering the entire breeding season, in three colonies of the Terceira Island (Azores). A total of 32 nests were sampled using motion-triggered cameras.

The multi-herbal extracts, an improved formular from Shenling Baizhu Powder, were used in our study to investigate its immune-enhancing effects and underling mechanisms. Based on UPLC-Q-TOF-MS and SPME-GC-MS analysis, 106 chemical compounds were identified from the extracts. In vitro assays indicated that the extracts could promote cell proliferation and NO secretion of RAW264.7 cells. RNA-seq and RT-qPCR showed that RAW264.7 cells treated with extracts increased the expression of pro-inflammatory factors IL-1β, iNOS, TNF-α, and TGF-β. Western-Blot revealed that the extracts could significantly enhance ERK phosphorylation level, and slightly increased JNK and p38 phosphorylation levels. These data suggest that multi-herbal extracts have a potential of regulating immune response via the JNK/p38/ERK signalling of MAPK pathways in RAW264.7 cells.

Accurate and rapid diagnosis of TMV is an essential pre-requisite for proactive and tailored disease management strategies, filling the gap between more rigorous laws regarding pesticide use and maintaining crop production. Herein, we developed a time-resolved fluorescence immunoassay (TRFIA) to quantitatively detect TMV in tobacco. TMV virions were used as immunogens to develop monoclonal antibodies, which were then conjugated to Eu3+ nanospheres. The detection limit of the TRFIA platform was 0.24 ng/mL, with recovery rates in the range of 90.71–108.11% in spiked tobacco. The specificity was confirmed using ten species of tobacco-infecting phytopathogens. In-field applicability was implemented by screening for TMV in 10,000 tobacco leaf samples collected from five fields in Kunming, China. Overall, the proposed TRFIA platform is rapid, accurate, and end-user friendly, demonstrating its application in TMV onsite testing in tobacco.","PeriodicalId":12300,"journal":{"name":"Food and Agricultural Immunology","volume":" ","pages":""},"PeriodicalIF":3.0,"publicationDate":"2023-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45615408","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}
