Abstract
Deoxynivalenol (DON) is a common mycotoxin in crops that could induce intestinal inflammation, affecting the susceptibility of intestinal epithelial cells (IECs) to pathogen infection. This study aimed to investigate DON's effects on mucin and cytokine production as part of the local immune system and how it affected intestinal susceptibility to pathogen infection. Caco-2 cells were exposed to DON followed by acute enteroinvasive Escherichia coli (EIEC) infection. An increase in EIEC attachment to DON-exposed cells was observed, probably in part, mediated by secretory MUC5AC mucins and membrane-bound MUC4 and MUC17 mucins. Additionally, DON with EIEC posttreatment led to significant changes in the gene expression of several proinflammatory cytokines (IL1α, IL1β, IL6, IL8, TNFα, and MCP-1), which may be in part, mediated by NK-κB and/or MAPK signaling pathways. These data suggested DON may exert immunomodulatory effects on IECs, altering the IEC susceptibility to bacterial infection.
Practical Application
The results suggested that DON might modulate immune responses by affecting mucus and cytokine production, which may affect the susceptibility of intestinal epithelial cells to pathogen infection.
期刊介绍:
The goal of the Journal of Food Science is to offer scientists, researchers, and other food professionals the opportunity to share knowledge of scientific advancements in the myriad disciplines affecting their work, through a respected peer-reviewed publication. The Journal of Food Science serves as an international forum for vital research and developments in food science.
The range of topics covered in the journal include:
-Concise Reviews and Hypotheses in Food Science
-New Horizons in Food Research
-Integrated Food Science
-Food Chemistry
-Food Engineering, Materials Science, and Nanotechnology
-Food Microbiology and Safety
-Sensory and Consumer Sciences
-Health, Nutrition, and Food
-Toxicology and Chemical Food Safety
The Journal of Food Science publishes peer-reviewed articles that cover all aspects of food science, including safety and nutrition. Reviews should be 15 to 50 typewritten pages (including tables, figures, and references), should provide in-depth coverage of a narrowly defined topic, and should embody careful evaluation (weaknesses, strengths, explanation of discrepancies in results among similar studies) of all pertinent studies, so that insightful interpretations and conclusions can be presented. Hypothesis papers are especially appropriate in pioneering areas of research or important areas that are afflicted by scientific controversy.
