Eddie James, PhD
Research Assistant Member, Tetramer Core Manager
Dr. James received his bachelor’s degree in Chemical Engineering from the University of Colorado. He subsequently attended Washington State University, receiving his PhD in Biochemical Engineering in 2001. After completing an internship at Zymogenetics, he joined the Benaroya Research Institute at Virginia Mason as manager of the tetramer core.
Areas of Research
The focus of the Tetramer Core Laboratory is to produce and develop MHC class II tetramer reagents to facilitate the study of T cells both within and outside BRI. T cells are difficult to detect and isolate using traditional methods, but can be labeled and detected directly using tetramers. Therefore, tetramers provide an effective and exciting approach for studying T cell responses. Because tetramers have only limited commercial availability, we produce these proteins “in house” using insect cell cultures and distribute them on a zero profit basis. We are continually expanding our repertoire of tetramers, applying them to study new diseases and larger segments of the population.
Dr. James is also involved in several collaborative research projects, applying tetramers to identify the chemical patters recognized by T cells in desirable protective immune responses directed against viruses (such as tetanus and HPV) and in undesirable destructive immune responses directed against self or therapeutic proteins (including GAD, insulin, and Factor VIII). Understanding the basics of immune recognition and the specifics of both immune protection and immune destruction will lead to better diagnostic tools and better therapies.
