Promiscuous Behavior of HPV16E6 Specific T Cell Receptor Beta Chains Hampers Functional Expression in TCR Transgenic T Cells, Which Can Be Restored in Part by Genetic Modification
Abstract
Background: T cell receptor gene transfer is a promising strategy to treat patients suffering from HPV induced malignancies. Therefore we isolated the TCRαβ open reading frames of an HPV16E6 specific CTL clone and generated TCR transgenic T cells. In general low level expression of the transgenic TCR in recipient human T cells is observed as well as the formation of mixed TCRs dimers. Here we addressed both issues employing three different expression platforms.
