Abstract

ABSTRACT Vermicompost tea (VCT) is the effluent or leachate with a honey-brown colour collected during vermicomposting, an ecologically significant process essential to today’s organic and regenerative agriculture. Dried earthworm, a.k.a. dilong (DL, meaning “earth dragon”) in traditional Chinese herbal medicine, has long been used as a key component to treat diverse skin diseases, including eczema. In the present study, we hypothesized that VCT might have a positive influence on eczema therapy. It was found that the oral application of 50% VCT in mouse model reduced the ear allergic scores and alleviated the histological changes caused by eczema. Furthermore, the levels of Th2-associated and pro-inflammatory cytokines (namely IL-4 and IL-13 in serum) and IgE (in serum and ear tissues) were significantly reduced by VCT. Therefore, oral administration of 50% VCT exerts immunomodulatory effects on the development of eczema, suggesting its potential as a nutraceutical candidate for eczema treatment. GRAPHICAL ABSTRACT

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.
