人工抗原在中药注射剂过敏反应研究中的应用与进展

中药注射剂中存在一些具有潜在致敏性的小分子物质,因相对分子质量太小而缺乏免疫原性,当其与合适的载体偶联后可导致过敏反应.因此,如何将小分子半抗原与载体偶联制备具有免疫原性和反应原性的完全抗原,是中药注射剂小分子致敏物质筛选的关键.作者从中药注射剂半抗原的特点、载体的选择和使用、偶联方法、完全抗原的纯化鉴定等方面论述了人工抗原抗体制备技术的最新研究情况及其在中药注射剂致敏物质筛选中的实验研究进展,以及免疫芯片技术在中药注射剂致敏物质研究中的应用前景,旨在为中药注射剂安全性控制提供新的实验研究思路和方法.

Application and advance of artificial antigens in studies on allergic reaction of traditional Chinese medicine injections

There are some small molecules with potential allergenicity in traditional Chinese medicine injections. They are lack of immunogenicity due to their small molecular weight, but they can lead to allergic reactions when they were coupled with appropriate vectors. Therefore, how to couple small molecule semi-antigens with vectors to prepare complete antigens with immunogenicity and reactogenicity is the key for screening small molecular allergenic substances out of traditional Chinese medicine injections. In terms of semi-antigen characteristics of traditional Chinese medicine injections, vector selection and application, coupling method and complete antigen purification and identification, the author introduces the latest research situations of artificial antigen and antibody preparation technology, the advance in experimental studies on screening of allergenic substances in traditional Chinese medicine injections, as well as the application prospect of immuno-chip technology in studies on allergenic substances in traditional Chinese medicine injections, with the aim of providing new experimental thoughts and methods for safety control of traditional Chinese medicine injections.
