摘要

免疫营养或通过食物和补充剂调节免疫能力已经获得了显著的重要性。水解胶原蛋白长期以来被用作功能性成分，具有多种生理活性，包括增强免疫功能。然而，胶原蛋白肽如何影响免疫系统仍需进一步研究。本研究以细胞因子mRNA表达为生物标志物，研究骨胶原肽(bone collagen peptides, BCP)对人单核THP-1和Jurkat T淋巴细胞系的免疫调节活性。体外，胃肠道消化和Caco-2细胞吸收可分别获得消化和吸收的BCP组分，并在免疫细胞上进行测试。结果表明:(1)对M0巨噬细胞有免疫刺激作用，而对M1巨噬细胞无免疫刺激作用(脂多糖激活);(2)吸收BCP部位孵育后T淋巴细胞增殖显著。(3)抗炎IL-10细胞因子生物标志物显著升高。这些结果表明BCP可能作为一种免疫营养素，调节免疫反应和炎症过程。缩写:ATCC:美式培养集BCP:骨胶原肽DMSO:二甲基亚砜FBS:胎牛血清ECM:细胞外基质GRAS:公认安全的;IFN:干扰素IL:白细胞介素LPS:脂多糖SEM:平均标准误差TEER:经上皮电阻

Immunomodulatory role of edible bone collagen peptides on macrophage and lymphocyte cell cultures

ABSTRACT Immunonutrition or modulation of immune capacity through food and supplements has been gaining significant importance. 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. Abbreviations: ATCC: American Type Culture Collection BCP: bone collagen peptide DMSO: dimethyl sulphoxide FBS: fetal bovine serum ECM: extracellular matrix GRAS: Generally recognized as safe; IFN: interferon IL: interleukin, LPS: lipopolysaccharide SEM: standard error of the mean TEER: transepithelial electrical resistance

期刊介绍： Food and Agricultural Immunology is an international open access journal publishing original immunological research with applications in food, agricultural, environmental and veterinary science. Submissions describing the use of immunological techniques and methods are particularly welcomed. The journal aims to expand our understanding of the interactions at the interface of food and immune systems including studies on: -Development of diagnostic systems – all types of ligand-based assays, e.g. antibody, aptamer -Application of ligand-based assays for the detection or identification of molecules of interest in food science, agricultural research, veterinary investigations and clinical systems relating to food allergy or sensitivity to agricultural chemicals -Effects of food on the immune system -Studies on allergy and allergic reactions -Investigations into food allergies -Development of allergen-free food systems -Development of novel assay formats -Applications of assay systems to the monitoring of food items in relation to safety and labelling -Food quality issues, e.g. speciation, adulteration and contamination -Comparisons between different analytical techniques The journal publishes research and review articles and is essential reading for food scientists, immunologists and all those concerned with the interaction between food and immune systems.
