Abstract
An artificial T cell adaptor molecule (ATAM) was generated to improve persistence of T cell receptor (TCR) gene-transduced T (TCR-T) cells compared to such persistence in a preceding study. ATAMs are gene-modified CD3ζ with the intracellular domain of 4-1BB inserted in the middle of CD3ζ. NY-ESO-1 TCR-T cells transduced with an ATAM with two separated virus vectors demonstrated superior proliferation upon antigen stimulation. To further develop clinically applicable ATAM-transduced TCR-T cells, we attempted to make a single virus vector to transduce the TCR and ATAM simultaneously. Because we failed to observe improved proliferation capacity upon stimulation after one virus vector (1vv) transduction, we compared TCR-T cells transduced with 1vv and two virus vector (2vv) methods to elucidate the reason. In Jurkat reporter cells, an ATAM transduced by the 2vv method demonstrated a higher intensity than by the 1vv method, and the ATAM intensity was associated with increased nuclear factor κB (NF-κB) signals upon stimulation. In ATAM-transduced primary T cells, a transduced ATAM by the 2vv method showed higher intensity and better proliferation. ATAM-transduced TCR-T cells demonstrated improved proliferation only when the ATAM was transduced at a higher intensity. To create a simpler transduction method, we need to develop a strategy to make a higher ATAM expression to prove the efficacy of ATAM transduction in TCR-T therapy.
