Engineering genetic circuit interactions within and between synthetic minimal cells.

Area of Science:

• Synthetic biology
• Bioengineering
• Biochemistry

Background:

• Genetic circuits and reaction cascades are crucial for synthetic biology, biochemistry, and bioengineering.
• Maximizing modularity, scalability, and flexibility in genetic circuit design remains an open challenge.
• Liposome encapsulation offers a method for isolating chemical reactions in well-defined environments.

Purpose of the Study:

• To adapt liposome encapsulation for modular and controlled compartmentalization of genetic circuits and cascades.
• To engineer synthetic minimal cells (synells) capable of hosting complex genetic cascades.
• To demonstrate external signal control and inter-liposomal communication without crosstalk.

Main Methods:

• Utilizing liposome encapsulation to create synthetic minimal cells (synells).
• Engineering synells to contain multi-part genetic cascades.
• Demonstrating controlled fusion of liposomes containing different cascades.
• Investigating control via external signals and inter-liposomal communication.

Main Results:

• Successfully engineered synells containing multi-part genetic cascades.
• Demonstrated precise control of genetic cascades by external signals.
• Achieved communication between liposomes without crosstalk.
• Showcased controlled fusion of liposomes to combine incompatible reaction products.

Conclusions:

• Liposome encapsulation enables modular creation of synthetic biology cascades.
• Synells offer enhanced control, scalability, and flexibility for genetic circuits.
• This approach is a significant step towards the programmability of synthetic biology systems.
