Structure-Guided T Cell Receptor Mutations That Alter Antigen Specificity, Cross-Reactivity, And Polyfunctional Phenotypes In Gene-Modified T Cells, Kendra Foley

Dissertations

Adoptive cell transfer of T cell receptor (TCR) gene-modified T cells targeting specific tumor antigens is currently in clinical trials for patients with advanced malignancies. Despite the clinical responses, there are still hurdles to be overcome in achieving an effective and safe therapy. One of the limitations in the success of this type of therapy is the potential for cross-reactivity and unanticipated off-target reactivity which could lead to autoimmunity. Adverse events encompassing these "off-target, off-tumor" cross-reactivities leading to autoimmunity have been seen in patients in different clinical trials. Here, we demonstrate a novel approach to improve antigen specific reactivity and …
