Summary
This study demonstrates cell-mimetic aggregation using polymer vesicles. Host-guest interactions between adamantane and cyclodextrin drive the formation of macroscopic vesicle aggregates and induce vesicle fusion.
Area of Science:
- Polymer chemistry and materials science
- Supramolecular chemistry
- Biomimetic materials
Background:
- Cell-sized polymer vesicles offer a platform for biomimetic studies.
- Host-guest molecular recognition is a key interaction in supramolecular assembly.
- Controlling vesicle aggregation and fusion is crucial for developing advanced materials.
Purpose of the Study:
- To achieve large-scale, cell-mimetic aggregation of polymer vesicles.
- To utilize host-guest interactions as the driving force for vesicle assembly.
- To investigate vesicle fusion during the aggregation process.
Main Methods:
- Synthesis of hyperbranched polymer vesicles (branched polymersomes, BPs) via self-assembly.
- Functionalization of BPs with adamantane (Ada-BPs) or β-cyclodextrin (CD-BPs).
- Characterization of host-guest interactions using NOESY and fluorescence methods; observation of aggregation and fusion via microscopy and assays.
Main Results:
- Macroscopic vesicle aggregates were successfully formed by mixing Ada-BPs and CD-BPs.
- Intervesicular host-guest recognition between β-cyclodextrin and adamantane confirmed as the driving force.
- Vesicle fusion events were frequently observed during aggregation, confirmed by multiple assays.
Conclusions:
- Demonstrated a scalable method for creating cell-mimetic vesicle aggregates.
- Established host-guest interactions as an effective strategy for controlling polymer vesicle assembly.
- Indicated that vesicle fusion is an integral part of this cytomimetic aggregation process.

01:45Vesicular Tubular Clusters
After budding out from the ER membrane, some COPII vesicles lose their coat and fuse with one another to form larger vesicles and interconnected tubules called vesicular tubular clusters or VTCs. These clusters constitute a compartment at the ER-Golgi interface known as ERGIC (Endoplasmic Reticulum Golgi Intermediate Compartment). The ERGIC is a mobile membrane-bound cargo transport system that sorts proteins secreted from ER and delivers them to the Golgi.

01:43SNAREs and Membrane Fusion
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...

01:26Fusion of Secretory Vesicles with the Plasma Membrane
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.

01:12Clathrin Coated Vesicles
Clathrin-coated vesicles use endocytosis to transport receptors and lysosomal hydrolases from the Golgi to the lysosome in the late secretory pathway. Clathrin-mediated endocytosis was the first described endocytic process, and Clathrin-coated vesicles remain one of the most well-studied transport vesicles. The molecular machinery that generates clathrin-coated vesicles comprises over 50 proteins that precisely coordinate vesicle formation. Cell surface receptors concentrated in indented sites...
00:59COP Coated Vesicles
Membrane-enclosed structures called vesicles transport proteins and lipids across the cell. The vesicles derive their cargo from the plasma membrane, Golgi, ER, or endosome. Coated vesicles are spherical, protein-coated carriers with a 50–100 nm diameter that mediate bidirectional transport between the ER and the Golgi. The distribution of proteins between the ER and Golgi complex is dynamic and is maintained by different coated vesicles. Their formation is driven by the assembly of different...
01:25Rab Cascades
Rab GTPases act in a regulated cascade during membrane fusion, helping the lipid bilayers mix. The Rab family of proteins are active when bound to GTP, and inactive when bound to GDP. Hence, they act as guanine nucleotide-dependent molecular switches. Rab-GTP recognizes and binds to long or short-range tethering proteins to capture the target vesicle. These tethers coordinate with SNAREs on the vesicle and the target membrane to assemble the trans SNARE complex that locks the mixing bilayers.
