| 摘要 |
Oxidative rearrangement and cleavage of hydroxy aromatic rings of quercitin moiety of Timothy grass pollen antigen or antigenic fragments gives rise to a modified antigen having no antigenic properties but retaining capability of activating T-cells for regulation of immune response. The invention includes the modified antigens, the method of oxidative cleavage, immunotherapeutic methods for alleviating allergic responses to the Timothy grass pollen antigens and immunotherapeutic compositions therefor.
