Exosomes have also been shown to carry double-stranded DNA. [25] Exosomes can transfer molecules from one cell to another via membrane vesicle trafficking, thereby influencing the immune system, such as dendritic cells and B cells, and may play a functional role in mediating adaptive immune responses to pathogens and tumors.
The exosome complex (or PM/Scl complex, often just called the exosome) is a multi-protein intracellular complex capable of degrading various types of RNA (ribonucleic acid) molecules. Exosome complexes are found in both eukaryotic cells and archaea , while in bacteria a simpler complex called the degradosome carries out similar functions.
Exosome biogenesis begins with pinching off of endosomal invaginations into the multivesicular body (MVB), forming intraluminal vesicles (ILVs). If the MVB fuses with the plasma membrane, the ILVs are released as "exosomes." The first publication to use the term "exosome" for EVs presented it as a synonym for "micro-vesicle."
The stem cell secretome consists of extracellular vesicles, [1] specifically exosomes, microvesicles, membrane particles, peptides and small proteins . The paracrine activity of stem cells, i.e. the stem cell secretome, has been found to be the predominant mechanism by which stem cell-based therapies mediate their effects in degenerative, auto ...
Exosome may refer to: Exosome complex, an intracellular macromolecular protein complex involved in RNA degradation; Exosome (vesicle), an extracellular vesicle ...
Exosomes are formed by invagination within a cell to create an intracellular vesicle called an endosome, or an endocytic vesicle. In general, exosomes are formed by segregating the cargo (e.g., lipids, proteins, and nucleic acids) within the endosome. Once formed, the endosome combines with a structure known as a multivesicular body (MVB). The ...

Exome sequencing is especially effective in the study of rare Mendelian diseases, because it is an efficient way to identify the genetic variants in all of an individual's genes.
