Summary
Researchers developed remote-controlled artificial cells that communicate with bacteria using light or temperature. These artificial organelles release signals to activate protein expression in *Escherichia coli*, enabling new biomedical and biotechnology applications.
Area of Science:
- Synthetic biology
- Biotechnology
- Biomedicine
Background:
- Intercellular communication is crucial for living systems.
- Engineering artificial cells for communication is a key area in synthetic biology.
- Current methods often lack external control over signal exchange.
Purpose of the Study:
- To engineer remote-controlled artificial organelles for intercellular communication.
- To develop artificial cells that translate physical stimuli into bacterial activation.
- To enable controlled interactions between artificial and living cells.
Main Methods:
- Designed two types of vesicle-based artificial organelles.
- Utilized light and temperature as external stimuli.
- Demonstrated activation of *Escherichia coli* protein expression via released signaling molecules.
Main Results:
- Artificial cell membranes were activated by light or temperature.
- Released signaling molecules successfully induced protein expression in bacteria.
- The artificial cells acted as the primary design unit for stimuli-responsive behavior.
Conclusions:
- Developed a novel approach for remote-controlled bacterial activation using artificial cells.
- Compartmentalizing stimuli-responsive elements in artificial cells offers therapeutic and engineering potential.
- This work lays the foundation for hybrid living/nonliving systems with temporal control over population interactions.

01:26Fusion of Secretory Vesicles with the Plasma Membrane
11.2K
Proteins and neurotransmitters in secretory vesicles can be released from a cell upon vesicle docking, priming, and fusion with the plasma membrane. Vesicles are docked and primed in preparation for the quick exocytosis of their contents in response to a stimulus. The fusion process is mainly carried out by a SNAP Receptor or SNARE complex, consisting of synaptobrevin, syntaxin-1, and SNAP-25.

01:33Overview of Secretory Vesicles
8.6K
Secretory vesicles, also known as dense core vesicles (DCVs), are membrane-bound vesicles that transport secretory proteins, such as hormones or neurotransmitters. Regulated secretory vesicles transport proteins from the trans-Golgi network to the exterior of the cell. Proteins present in regulated secretory vesicles are required to be rapidly exocytosed in large amounts upon a specific stimulus.
Various proteins regulate the aggregation of molecules inside the secretory vesicles. Chromogranins...

01:30Bacterial Signaling
33.6K
Bacterial signaling can occur within bacteria (intracellular) or between bacteria (intercellular). At times, a group of bacteria behaves like a community. To achieve this, they engage in quorum sensing, the perception of higher cell density that causes changes in gene expression. Quorum sensing involves both extracellular and intracellular signaling. The signaling cascade starts with a molecule called an autoinducer (AI). Individual bacteria produce AIs that move out of the bacterial cell...

01:10Intracellular Movement of Viruses and Bacteria
2.9K
Intracellular bacteria and viruses often comprise a group of highly infectious pathogens that can cause several diseases. Bacterial pathogens include those belonging to the genus Rickettsia responsible for conditions such as rocky mountain spotted fever and the Mediterranean spotted fever; Chlamydia, a genus responsible for a sexually transmitted disease; Coxiella burnetii, an agent responsible for Q fever. Viral pathogens include vaccinia—a poxvirus, and herpes simplex virus—a...

01:38Intralumenal Vesicles and Multivesicular Bodies
3.6K
Intraluminal vesicles (ILVs) are small vesicles 50-80 nm in diameter formed during the maturation of early endosomes. A specialized endosome containing numerous ILVs is called a multivesicular body (MVB). ILVs contain internalized molecules such as antigens, nucleic acids, proteins, and metabolites. Some of these molecules are released from the MVBs inside exosomes and are transported to other cells. Other MVBs contain molecules that are retained in the ILVs and are later degraded within the...

01:43SNAREs and Membrane Fusion
11.0K
Once a transport vesicle has recognized its target organelle, the vesicular membrane needs to fuse with the target membrane to unload the cargo. Transmembrane proteins called SNAREs present on organelle membranes and their vesicles, mediate vesicle fusion.
SNAREs exist in pairs that symmetrically interact and catalyze the fusion of the lipid bilayers in vesicle and target organelle. v-SNARE in the vesicle membrane are single polypeptide chains that bind to a complementary t-SNARE, composed of 2...
