Summary
Helicobacter pylori outer membrane vesicles (OMVs) are key to extra-gastric diseases and chronic infections. These OMVs show promise as a vaccine candidate, but challenges remain regarding immunogenicity and safety.
Area of Science:
- Microbiology
- Immunology
- Pathogenesis
Background:
- Helicobacter pylori is linked to gastroduodenal diseases and extra-gastric conditions.
- The role of H. pylori-derived outer membrane vesicles (OMVs) in these diseases is under investigation.
- OMVs facilitate the delivery of bacterial virulence factors and contribute to pathogenesis.
Purpose of the Study:
- To review recent advances in understanding H. pylori OMVs.
- To explore the biogenesis mechanisms and biological functions of H. pylori OMVs.
- To discuss the potential of H. pylori OMVs as vaccine candidates.
Main Methods:
- Literature review of current research on H. pylori OMVs.
- Analysis of studies on OMV biogenesis and function.
- Evaluation of OMV properties relevant to vaccine development.
Main Results:
- H. pylori OMVs are involved in delivering virulence factors to induce extra-gastric diseases.
- OMVs contribute to bacterial survival and chronic gastric pathogenesis.
- H. pylori OMVs possess immunogenic properties, making them potential vaccine candidates.
Conclusions:
- H. pylori OMVs play a significant role in both gastric and extra-gastric pathogenesis.
- The unique characteristics of H. pylori OMVs present opportunities and challenges for vaccine development.
- Further research into OMV biogenesis and contents is crucial for advancing H. pylori therapeutics and vaccines.

3.4K
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...

00:59COP Coated Vesicles
7.7K
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...

01:45Vesicular Tubular Clusters
2.5K
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.

01:33Overview of Secretory Vesicles
8.5K
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...

6.9K
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...

Prokaryotes are small unicellular organisms that include the domains — Archaea and Bacteria. Bacteria include many common microorganisms, such as Salmonella and E. coli, while the Archaea include extremophiles that live in harsh environments, such as volcanic springs.
Like eukaryotic cells, all prokaryotic cells are surrounded by a plasma membrane, have genetic material in the form of single, circular DNA, a cytoplasm that fills the interior of the cell, and ribosomes that synthesize...
