Summary
A novel catanionic surfactant, ModCD14-BHD, self-assembles into unilamellar vesicles in water. This new surfactant, formed from cyclodextrin and a cationic surfactant, shows potential for biomedical applications.
Area of Science:
- Supramolecular Chemistry
- Materials Science
- Nanotechnology
Background:
- Catanionic surfactants offer unique self-assembly properties.
- Cyclodextrins are versatile host molecules with potential in drug delivery.
- Designing novel surfactants is crucial for advanced materials development.
Purpose of the Study:
- To synthesize and characterize a new catanionic surfactant, ModCD14-BHD.
- To investigate the self-assembly behavior of ModCD14-BHD in aqueous solutions.
- To explore the potential applications of the synthesized surfactant in biomedical fields.
Main Methods:
- Synthesis of ModCD14-BHD from benzyl-n-hexadecyldimethylammonium chloride (BHDC) and modified beta-cyclodextrin (Mod-β-CD14).
- Characterization of vesicle formation using dynamic light scattering (DLS), transmission electron microscopy (TEM), and scanning electron microscopy (SEM).
- Structural analysis using 1H NMR spectroscopy to understand the inclusion complex formation.
Main Results:
- ModCD14-BHD spontaneously forms unilamellar vesicles in water, unlike its individual components.
- Vesicle formation is attributed to the inclusion complex between cyclodextrin units and the surfactant's hydrocarbon chain.
- The formed vesicles possess available cavities for potential guest interactions.
Conclusions:
- A novel catanionic surfactant, ModCD14-BHD, has been successfully synthesized.
- The surfactant self-assembles into unilamellar vesicles, driven by host-guest complexation.
- ModCD14-BHD exhibits promising properties for applications in pharmaceutical and biomedical sciences.

7.3K
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...

01:32Pinching-off of Coated Vesicles
3.3K
Vesicle budding is orchestrated by distinct cytosolic proteins such as adaptor proteins, coat proteins, and GTPases. To initiate vesicle budding, membrane-bending proteins containing crescent-shaped BAR domains bind to the lipid heads in the bilayer and distort the membrane to form a protein-coated vesicle bud. Adaptors proteins such as AP2 for clathrin-coated vesicles can nucleate on the deformed membrane. Finally, coat proteins such as clathrin or COPI and COPII assemble into a coat forming...

2.6K
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.

9.7K
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...

01:33Overview of Secretory Vesicles
8.7K
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...
