Abstract

ABSTRACT Shenling Baizhu Powder is a traditional Chinese medicine formula that has been used for thousands of years to invigorate spleen, nourish stomach and regulate immune function. The multi-herbal extracts, an improved formular from Shenling Baizhu Powder, were used in our study to investigate its immune-enhancing effects and underling mechanisms. Based on UPLC-Q-TOF-MS and SPME-GC-MS analysis, 106 chemical compounds were identified from the extracts. In vitro assays indicated that the extracts could promote cell proliferation and NO secretion of RAW264.7 cells. RNA-seq and RT-qPCR showed that RAW264.7 cells treated with extracts increased the expression of pro-inflammatory factors IL-1β, iNOS, TNF-α, and TGF-β. Western-Blot revealed that the extracts could significantly enhance ERK phosphorylation level, and slightly increased JNK and p38 phosphorylation levels. These data suggest that multi-herbal extracts have a potential of regulating immune response via the JNK/p38/ERK signalling of MAPK pathways in RAW264.7 cells. 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.
