CRISPR technology is revolutionizing immunotherapy by enabling precise genetic engineering of immune cells. Using custom sgRNAs, researchers can enhance CAR-T and TCR therapies, improving efficacy, safety, and patient outcomes.

CRISPR in Immune Cell Engineering

CRISPR-mediated gene editing allows:

● Knocking out inhibitory receptors: Such as PD-1 or CTLA-4 to boost T-cell activity.

● Optimizing antigen recognition: Enhancing CAR or TCR specificity toward tumor cells.

● Improving persistence: Modifying metabolic or survival pathways in engineered cells.

These modifications can enhance the therapeutic potential of immune cells in cancer treatment, infectious diseases, and autoimmune disorders.

Applications in Research

● CAR-T therapy development: sgRNAs guide the knockout of immune checkpoints to improve tumor clearance.

●  TCR engineering: Precise edits enhance receptor affinity and minimize off-target recognition.

● Safety optimization: Targeted sgRNAs reduce the risk of cytokine release syndrome or graft-versus-host disease.

Technical Challenges

Efficient delivery of sgRNAs into primary immune cells, minimizing off-target effects, and ensuring stable expression are critical considerations. Custom design of sgRNAs is essential to maximize editing efficiency while maintaining cell viability.
