Multiplex engineering and multifunction T cells for precise and effective immunotherapies

Area of Science:

• Oncology
• Immunology
• Biotechnology

Background:

• Adoptive T cell transfer is a cornerstone of cancer immunotherapy.
• Current T cell therapies face limitations including T cell exhaustion, poor tumor infiltration, toxicity, and antigen escape.

Purpose of the Study:

• To review the potential of advanced cellular engineering technologies for improving adoptive T cell therapy.
• To discuss multiplex engineering of T cells to overcome existing therapeutic challenges.

Main Methods:

• Review of current viral and non-viral genetic engineering technologies (e.g., CRISPR-Cas9).
• Focus on engineering single T cells at multiple loci and conferring novel functions.
• Analysis of methodologies and rationales for designing advanced engineered T cells.

Main Results:

• Advanced engineering can address limitations of first-generation T cell therapeutics.
• Multiplex-engineered T cells show promise in preclinical and emerging clinical data.
• Engineering strategies can enhance T cell persistence, trafficking, and tumor targeting.

Conclusions:

• Multiplex T cell engineering significantly expands the potential of adoptive immunotherapy for cancer treatment.
• Further research is needed to optimize advanced cell engineering and fill remaining gaps for enhanced efficacy.
