TCR Library

January 16, 2024/in Partners, Synbio Libraries, Twist/by Harshita Sharma

TCR Libraries

Adoptive cell therapy (ACT) has transformed treatment options for patients with advanced or refractory cancers by redirecting the immune system to recognize and eliminate malignant cells.

Engineered TCR therapies represent a major branch of ACT, using synthetic or optimized T-cell receptors to target tumor-specific antigens. The workflow typically begins with sequencing the tumor biopsy to identify actionable mutations and the peripheral blood to map the patient’s TCR repertoire.

TCR repertoire profiling can be performed using bulk or single-cell sequencing, each offering distinct advantages:

Bulk sequencing provides broad coverage of the repertoire and captures large numbers of clonotypes, but does not preserve α–β chain pairing.
Single-cell sequencing preserves α–β receptor pairing and full receptor architecture, but at a much lower throughput than bulk methods.

But.... Why Twist for TCR Library Construction?

Twist’s combinatorial TCR library platform gives you the power to systematically reshape and expand your TCR landscape. Instead of being limited to naturally occurring α–β pairs, you can mix and match chains to uncover novel receptor combinations with therapeutic potential.

This approach pairs especially well with bulk repertoire sequencing, where α–β pairing is not preserved. Combinatorial assembly fills that gap by generating all possible pairings across defined alpha and beta chains.

Example:
A library built from 4 α-chains and 4 β-chains yields 16 unique α–β combinations — complete coverage, not a partial subset.

Performance Data You Can Rely On

TCR discovery isn’t limited by ideas — it’s limited by how fast you can screen and rebuild candidates. The real bottleneck comes from needing to evaluate large numbers of alpha–beta pairings to find the rare binders that actually matter.

Combinatorial TCR Libraries break that bottleneck.

By shuffling alpha and beta chains across all possible pairings, these libraries recreate a dramatically broader search space than what exists in the native repertoire. Instead of being restricted to the pairings captured in your sequencing data, you can now generate thousands of rationally designed combinations in a single build.

This enables teams to:

Scale screening throughput by producing many more testable TCR variants
Expand functional diversity beyond naturally occurring pairings
Capture rare or non-intuitive binders that would never appear in arrayed or bulk sequencing formats
Shorten discovery timelines by moving directly from variant design → library synthesis → high-throughput screening

For support implementing combinatorial TCR libraries into your discovery workflow, Twist Bioscience and Decode Science can provide hands-on guidance and localized expertise.

T Cell Receptor (TCR) Discovery workflow

Partner with Twist Bioscience to accelerate the identification and development of advanced cell therapies using large-scale, highly diverse T-cell receptor (TCR) libraries.

Twist provides highly uniform, NGS-verified libraries composed of precise, user-defined combinations of alpha and beta gene fragments. These libraries enable:

Comprehensive Screening: Efficiently test all desired TCR combinations to uncover high-affinity, functional receptors.
Customizable Design: Define specific alpha-beta pairings to target particular antigens or therapeutic applications.
High Uniformity: Libraries are optimized for reproducibility and coverage, ensuring consistent performance across screens.

CAR Library

In recent years, chimeric antigen receptor (CAR) T-cell therapy has emerged as a promising form of immunotherapy, offering new avenues for cancer treatment. Advances in gene transfer technology and gene editing, coupled with innovative CAR designs, have propelled the development of novel cancer therapies. However, despite these strides, several challenges remain, necessitating further research and development efforts to accelerate progress in the field.

CARs typically comprise an extracellular binding domain, a hinge region, a transmembrane domain, and one or more intracellular domains. Fine-tuning each component of the CAR is crucial for enhancing T cell specificity, antigen recognition, and overall T cell function. Studies have demonstrated that even minor modifications to the CAR can significantly impact therapeutic outcomes. Therefore, it is imperative to have a comprehensive library for thorough testing, considering the complexity of each CAR construct.

Twist has pioneered a groundbreaking technology for constructing CAR libraries, allowing seamless shuffling of variants within each domain through a scarless assembly process. The key benefits of this technology include high diversity and quality, with each combinatorial assembly accommodating up to 10,000 gene fragment combinations. NGS-verified libraries ensure that over 90% of possible variants are present within 10 times of the mean. The flexibility and customization options offered by Twist’s technology allow users to design TCR and CAR libraries with user-defined combinatorial variants across specific elements. Additionally, the platform provides flexibility in throughput, enabling the insertion of sequences up to 1.5 kb in length and designing libraries at scale with diversity across multiple elements of the sequence. Twist’s technology represents a significant advancement in the development and optimization of CAR T-cell therapies.

The process begins with synthesizing genes representing different sequence variants for each domain of the Chimeric Antigen Receptor (CAR). These domains, including the extracellular binding domain, hinge region, transmembrane domain, and intracellular domains, can consist of multiple sequence variations. Twist then combines these synthesized genes through a scarless assembly process. This unique assembly method ensures that the combination of these genes results in a highly diverse library for scaffold optimization.

The scarless assembly process enables the seamless merging of the gene variants, creating a comprehensive library that spans a wide range of potential combinations. This technology allows for the exploration of unique domain combinations, unveiling novel functionalities within the CAR scaffold.

The workflow for Chimeric Antigen Receptor (CAR) discovery and optimization involves studying how each domain of the CAR scaffold independently and synergistically influences its functionality. CAR Libraries, generated through this technology, act as a valuable tool for fine-tuning each module. This process helps uncover codependencies among the domains and provides a deeper understanding of their impact on T-cell specificity, antigen recognition, and overall T-cell function.

Researchers can partner with Twist at any stage of their discovery workflow, leveraging both in vivo and in vitro workflows for binder discovery and optimization. Additionally, the use of synthetic libraries from Twist enhances scaffold optimization and validation, providing a versatile and efficient approach to advancing CAR T-cell therapy research and development.
