Hydrolysed collagen has long been used as a functional ingredient, showing multiple physiological activities, including enhancement of immune functions. However, how collagen peptides may affect the immune system still needs further research. This study investigates bone collagen peptides (BCP) immunomodulatory activity on human monocytic THP-1 and human Jurkat T lymphocyte cell lines, using cytokine mRNA expressions as biomarkers. In vitro, gastrointestinal digestion and Caco-2 cell absorption allow obtaining digested and absorbed BCP fractions, respectively, which are tested on immune cells. Results show: (1) Immunostimulatory effect on M0 macrophages, but not on M1 macrophages (lipopolysaccharide (LPS)-activated), (2) Significant T lymphocyte proliferation after incubation with absorbed BCP fraction. (3) Significant increase of anti-inflammatory IL-10 cytokine biomarker. These results suggest that BCP could act as an immunonutrient, modulating the immune response and inflammatory processes.

This study was designed to determine the content of the main chemical components and elucidate the antioxidant and anti-inflammatory capacity of G. procumbens flowers extracts (GPFE). GPFE was rich in flavonoids and phenolics and exhibited great reducing power as well as strong scavenging ability of ABTS+ and DPPH radicals. The pro-inflammatory factors including IL-6, IL-1β, NO, TNF-α, PGE2 and their mRNA transcriptions were strongly inhibited with the treatment of GPFE in LPS-stimulated RAW264.7 macrophages. Meanwhile, GPFE could attenuate the inflammation via suppressing the nuclear translocation of NF-κB p65 and downregulating the MAPK signalling pathways. Furthermore, isochlorogenic acid B, isochlorogenic acid A and isochlorogenic acid C isolated from GPFE all had a high content and showed potent anti-inflammatory activities. Our findings suggest that GPFE could be used as a natural anti-inflammatory agent.","PeriodicalId":12300,"journal":{"name":"Food and Agricultural Immunology","volume":"2 4","pages":""},"PeriodicalIF":3.0,"publicationDate":"2022-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138504068","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}

EL tissue cultures can overcome the shortage of material; however, the anti-inflammatory property of such cultures has not been investigated. Herein, we evaluated the anti-inflammatory effects of root and callus cultures of EL and of a related species, Eurycoma harmandiana Pierre (EH), on lipopolysaccharide-activated RAW 264.7 cells. Eurycomalactone and 9-methoxycanthin-6-one were the predominant compounds in EL calli. Eurycomanone content was 0.283 mg/g in EL root culture and 0.348 mg/g in intact roots. The extracts of the root and callus cultures significantly inhibited nitric oxide production, and inhibited the expression of iNOS, IL-6, and COX-2 genes. Overall, the tissue cultures of EH and EL produced eurycomanone, chaparinone, eurycomalactone, 9-hydroxycanthin-6-one, canthin-6-one, and 9-methoxycanthin-6-one, which exhibited anti-inflammatory effects. These tissue cultures may be a valuable and sustainable source of active ingredients effective against inflammatory conditions.","PeriodicalId":12300,"journal":{"name":"Food and Agricultural Immunology","volume":"33 1","pages":"530 - 545"},"PeriodicalIF":3.0,"publicationDate":"2022-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45310638","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}

It has previously exhibited antioxidant, anti-pathogenic, and anti-inflammatory activities. Our study aimed to investigate the anti-melanogenic effect of Cypress Tree Bark extract (CBE). We evaluated cellular tyrosinase activity and melanin content in alpha-melanocyte-stimulating hormone (α-MSH) induced B16F10 murine melanoma cells. We analyzed microphthalmia-associated transcription factor (MITF), tyrosinase-related protein (TRP1 and TRP2), and cAMP response element-binding protein (CREB) activation via phosphorylation of AKT and ERK using western blot analysis. Tyrosinase, MITF, TRP1, and TRP2 mRNA expression were examined via real-time polymerase chain reaction. CBE restored melanin content and tyrosinase activity remarkably in α-MSH stimulated melanoma cells. It exhibited an anti-melanogenic effect through suppressing MITF, TRP1, TRP2, tyrosinase mRNA and protein expression in α-MSH-induced B16F10 cells. Furthermore, CBE has significantly inhibited CREB activation by suppressing AKT and extracellular signal-regulated kinase phosphorylation. Our data strongly suggest that CBE has potential effects against melanogenesis.
