Background:
- Lactic acid bacteria (LAB) are vital in food fermentation and human health.
- Bacterial extracellular vesicles (EVs) are key mediators of microbe-host interactions.
- LAB-EV biogenesis involves cell-wall integrity mechanisms like prophage systems.
Purpose of the Study:
- To review recent advances in LAB-EV biology.
- To outline considerations for harnessing LAB-EVs in biomedicine and food science.
- To highlight the need for mechanistic evaluations and standardized production.
Main Methods:
- Review of current scientific literature on LAB-EVs.
- Analysis of LAB-EV biogenesis pathways.

01:31Lysosomes
Lysosomes are membrane-enclosed spherical sacs derived from the Golgi apparatus. The most important function of the lysosome is degrading macromolecules and biological polymers that are released during membrane trafficking events such as the secretory, endocytic, autophagic, and phagocytic pathways. The degradation is carried out by several hydrolytic enzymes active in an acidic environment of the lysosomal lumen. These acid hydrolases are involved in cellular processes such as cell signaling,...
01:38Intralumenal Vesicles and Multivesicular Bodies
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...
