Summary
Non-vesicular extracellular nanoparticles (NVEPs), like exomeres and supermeres, are distinct from extracellular vesicles (EVs). These membraneless particles show promise as disease biomarkers and therapeutic targets.
Area of Science:
- Biochemistry
- Cell Biology
- Nanotechnology
Background:
- Extracellular vesicles and particles (EVPs) exhibit significant diversity and complexity.
- Recent research highlights non-vesicular extracellular nanoparticles (NVEPs) as potential disease biomarkers.
- NVEPs differ from extracellular vesicles (EVs) by lacking a membrane and having smaller sizes.
Purpose of the Study:
- To review the biogenesis and contents of exomeres and supermeres, two types of membraneless NVEPs.
- To compare NVEPs with other EVPs, particularly EVs.
- To discuss isolation, identification, applications, and future research directions for NVEPs.
Main Methods:
- Literature review of recent studies on NVEPs, exomeres, and supermeres.
- Comparative analysis of NVEPs and EVs based on structural and compositional characteristics.
- Discussion of current and emerging techniques for NVEP isolation and identification.
Main Results:
- NVEPs, including exomeres and supermeres, are enriched with bioactive molecules like proteins and RNAs.
- These nanoparticles possess unique features distinct from membrane-bound EVs.
- Exomeres and supermeres are implicated in intercellular communication and disease processes.
Conclusions:
- NVEPs represent a novel class of extracellular nanoparticles with significant potential.
- Further research into NVEPs could lead to advancements in disease diagnostics and therapeutics.
- Understanding NVEP biogenesis and function is crucial for clinical translation.

01:36Overview of Exosomes
2.7K
Exosomes are stable, lipid bilayer-enclosed vesicles capable of crossing biological barriers. They can carry a wide range of molecules required for intercellular communication. Once exosomes are released from the cell where they originated, they enter a recipient cell through various pathways such as fusion, receptor-mediated endocytosis, macropinocytosis, and phagocytosis.

1.9K
Cell division and enlargement are processes that require precise control. The control ensures that cell division cannot proceed unless the cell has grown to a specific size. A spherical, dividing cell requires an approximately 1.6X increase in its surface area to double its volume. The secretory pathway also has a significant role in cell membrane enlargement. Secretory vesicles that bud off from the Golgi apparatus and later fuse with the plasma membrane during exocytosis are a major source of...

The mitochondrial cristae membrane is the primary site for the oxidative phosphorylation (OXPHOS) process of energy conversion mediated through respiratory complexes I to V. These complexes have been widely studied for decades, and it has been proven that they form supramolecular structures called respiratory supercomplexes (SC). These higher-order complexes may be crucial in maintaining the biochemical structure and improving the physiological activity of the individual complexes while...

The translocon complex situated on the ER membrane is the main gateway for the protein secretory pathway. It facilitates the transport of nascent peptides into the ER lumen and their insertion into the ER membrane.
Sec61 protein conducting channel
In eukaryotes, the translocon complex comprises a core heterotrimeric translocator channel called the Sec61 complex. This channel includes three transmembrane proteins, Sec61α, Sec61β, and Sec61γ, and is the largest subunit of the...

3.3K
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...

7.0K
A proteome is the entire set of proteins that a cell type produces. We can study proteomes using the knowledge of genomes because genes code for mRNAs, and the mRNAs encode proteins. Although mRNA analysis is a step in the right direction, not all mRNAs are translated into proteins.
Proteomics is the study of proteomes' function. It involves the large-scale systematic study of the proteome to denote the protein complement expressed by a genome. Scientist Mark Wilkins coined the term...
