Fig. 1From: Exploring the potential link between MitoEVs and the immune microenvironment of periodontitis based on machine learning and bioinformatics methodsOccurrence and characterization of MitoEVs: an example of mitochondria-rich exosomes. Mitochondria-derived exosomes are formed through the accumulation of proteins, nucleic acids, and lipids synthesized by the endoplasmic reticulum, where the Golgi apparatus mediates the formation of outgrowth structures characterized by vesicles. Subsequently, these vesicles merge with the plasma membrane and are then liberated into the extracellular milieu, culminating in the formation of MitoEVsBack to article page
