Abstract

ABSTRACT Recently, there have been reports on the immunomodulatory properties of polysaccharides (PP), oligosaccharides (PO), and mixtures of PO/PP derived from Porphyra. To explore their potential in alleviating allergic responses and enteric dysbiosis, this study delved deeper into their effects using a murine model of food allergy. Daily administration of Porphyra samples mitigated allergic diarrhea, enteritis, and allergen-specific IgE production. Moreover, Porphyra samples exerted a significant reduction in the secretion of IL-2, IL-4, IFN-γ, and IL-17A, along with an elevation in the IL-10/IL-4 ratio in splenocytes upon allergen stimulation. Similarly, expression of IL-4 and IFN-γ in the duodenum was suppressed. Notably, allergic mice displayed a distinct fecal microflora profile compared to that of normal mice. Interestingly, PP and PO treatments exhibited different effects on improving enteric dysbiosis. These findings collectively suggest the potential of PP and PO as functional food candidates for the management of allergic enteritis and dysbiosis.

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.
