Abstract:The gene transfer of alpha and beta chains derived from a defined TCR has been successfully applied to endow T cells with specificities directed against tumor-associated antigens. However, it is still unclear if the transfer of TCR genes into T cells that already express an endogenous TCRalpha and beta chain leads to engineered T cells expressing four different TCR complexes on their cell surface. Mixed TCR heterodimers composed of endogenous and exogenous TCR chains may acquire new specificities, which may ca… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
