- Lethal toxins show potential as cancer therapies but face limitations due to systemic adverse effects.
- Effector cells engineered to resist toxins can deliver them specifically to tumors, minimizing side effects.
- Resistance to toxins like Pseudomonas aeruginosa exotoxin A (PE) was achieved by modifying the diphthamide biosynthesis pathway or EEF2.
- This approach enables effector cells to produce targeted immunotoxins that kill cancer cells expressing specific antigens.
- The study provides a foundation for developing armored effector cells capable of delivering potent toxins to tumors.
- Potential applications include extending this platform to primary autologous or allogeneic therapeutic cell types.
