abstract = {To facilitate preclinical testing of T-cell receptors
(TCRs) derived from tumor-reactive T-cell clones it is
necessary to develop convenient and rapid cloning strategies
for the generation of TCR expression constructs. Herein, we
describe a pDONR™221 vector backbone allowing to generate
Gateway™ compatible entry clones encoding optimized
bicistronic αβTCR constructs. It harbors P2A-linked TCR
constant regions and head-to-head-oriented recognition sites
of the Type IIS restriction enzymes BsmBI and BsaI for
seamless cloning of the TCRα and TCRβ V(D)J regions,
respectively. Additional well-established TCR optimizations
were incorporated to enhance TCR functionality. This
included replacing of the human αβTCR constant regions
with their codon-optimized murine counterparts for
chimerization, addition of a second interchain disulfide
bond and arrangement of the TCR chains in the order
β-P2A-α. We exemplified the utility of our vector backbone
by cloning and functional testing of three melanoma-reactive
TCRs in primary human T cells.},
