Human IgE-FcεRI chip assay to screen natural products for antipruritic activity
A biochip assay provides high-throughput and multiplexed analysis of biological samples, chemicals, and natural products. Pruritus is itchiness due to several causes, such as allergy, dry skin, pregnancy, liver disease, kidney disease, and thyroid disease. Treatment of pruritus is associated with reduced immunoglobulin (IgE) and FcεRI levels in sera. Treatment of pruritus include corticosteroid creams or ointment. However, they have side effects, so we need a safer treatment using natural products. Here, we developed an assay using protein chip technology to identify natural products with antipruritic activity that inhibit IgE-FcεRI binding. Of the 28 tested natural product extracts, Corni Fructus extract inhibited human IgE-FcεRI binding and also showed anti-histamine effects in MC/9 mast cells. These results suggest that this protein biochip assay system can be used to identify promising natural product extracts for the treatment of pruritus.
期刊介绍：
Sensing and Bio-Sensing Research is an open access journal dedicated to the research, design, development, and application of bio-sensing and sensing technologies. The editors will accept research papers, reviews, field trials, and validation studies that are of significant relevance. These submissions should describe new concepts, enhance understanding of the field, or offer insights into the practical application, manufacturing, and commercialization of bio-sensing and sensing technologies.
The journal covers a wide range of topics, including sensing principles and mechanisms, new materials development for transducers and recognition components, fabrication technology, and various types of sensors such as optical, electrochemical, mass-sensitive, gas, biosensors, and more. It also includes environmental, process control, and biomedical applications, signal processing, chemometrics, optoelectronic, mechanical, thermal, and magnetic sensors, as well as interface electronics. Additionally, it covers sensor systems and applications, µTAS (Micro Total Analysis Systems), development of solid-state devices for transducing physical signals, and analytical devices incorporating biological materials.
