CAR-T Cell Engineering

CAR-T cell engineering is at the forefront of personalized cancer immunotherapy, reprogramming T cells to become precision-targeting tools that homing devices against malignancies. Alfa Cytology's platform provides patent engineering coverage of the full CAR-T cell development workflow from design to scalable manufacture and quality assurance.

Introduction to CAR-T Cell Engineering

CAR-T cell engineering-the integration of cutting-edge capabilities in gene editing, molecular design and manufacturing optimization that enable the development of potent, personalized therapies for patients. This novel method allows for T cells to be engineered precisely so that they can effectively target and kill cancer cells. With solutions for limited cell persistence, tumor microenvironment resistance, and scalable production, CAR-T cell engineering is positioned to make next-generation immunotherapies a reality with durable clinical outcomes.

These services encompass the entire CAR-T cell development process, ensuring that every phase-from construct design and gene editing to manufacturing and quality assurance-is executed with precision and tailored to your specific requirements.

T-Cell Isolation and Activation

T Cell Isolation

Peripheral blood mononuclear cells (PBMCs) are collected and processed to enrich for T cells using state of the art separation techniques. This ensures that a high-quality T cell population is obtained for subsequent manipulation.

T Cell Activation

Following isolation, T cells are activated using CD3ζ/CD28 beads or specific cytokine cocktails. This activation step is essential to stimulate proliferation and prime the T cells for efficient genetic modification, enhancing their responsiveness to the engineered CAR.

T Cell Transduction

A tool is needed for the delivery of the foreign gene into human cells. At present, there are two ways to accomplish gene incorporation with vectors, i.e., viral systems and non-viral systems.

Delivery system Cargo/payload Example targeting mechanism Advantages
Viral vector Lentivirus Single-stranded RNA genome Engineered envelope with scFv (anti-CD3/ CD4/CD8)
  • Quiescent cells, including naïve/stem memory T cells are transducible
  • The integrated transgene is maintained throughout T cell expansion and can therefore support long-term activity of redirected T cells
  • Vector manufacturing protocols are well established.
AAV Single-stranded DNA genome Capsid bound scFv
  • Episomal persistence without integration provides long term transgene expression while minimizing the risk of insertional mutagenesis
  • Significant clinical experience exists with AAV gene therapy vectors for other indications.
  • Vector manufacturing protocols are well established.
Non-viral nanoparticle LNP mRNA Antibody (anti-CD3, CD8, CD5)
  • Transient expression is a built-in safety feature
Polymer mRNA
DNA
Antibody (anti-CD3) linked via polyglutamic acid to polymer
  • Suitable for the delivery of both DNA and mRNA
  • DNA payload can be integrating transposon DNA or non-integrating plasmid DNA
  • Transient expression of mRNA or non-integrating DNA is a built-in safety feature
  • PBAE polymer nanoparticles are biodegradable with a short half-life (1–7 h) and are thus nontoxic
    Polymer is amenable to the addition of targeting ligands.

T Cell Expansion

Post-transduction, the CAR‑T cells are cultured in controlled bioreactor environments. The expansion process is optimized through precise control of the cytokine milieu and co‑stimulatory signals, ensuring robust proliferation and long‑term functionality while maintaining safety and quality standards.
