The prevalence of RA in the world ranges from 0.5 to 1.0. Proteomics analysis identified mitochondria specific and extracellular vesicle associated proteins in sorted circulating cell-free human mitochondria. Rheumatoid arthritis (RA) is one of the most common chronic autoimmune inflammatory diseases. Circulating mitochondria were able to enter rho-zero cells, and were visualized using immunoelectron microscopic imaging. Both murine and human circulating cell-free mitochondria maintained a transmembrane potential. Murine and human mitochondria-containing MPs were positive for the platelet marker CD41 and the endothelial cell marker CD144, while hematopoietic CD45 labeling was low. Transgenic mice expressing mitochondrial-GFP showed GFP positivity in plasma MPs. Murine and human platelet-depleted plasma showed a cluster of MPs positive for the mitochondrial probe MitoTracker. They appear dressed in miniature mining outfits. 1 Like the Knockers of Cornish folklore they often help miners to the richest veins of ore or other treasures by their peculiar knocking sound. To test this, circulating MPs were analyzed using flow cytometry and proteomics. Coblynau are mythical gnome -like creatures that are said to haunt the mines and quarries of Wales and areas of Welsh settlement in America. Briefly, eligible patients were 18 years of age, had adult-onset RA for 3 months as defined by the 1987 American College of Rheumatology (ACR) criteria, and showed an unsatisfactory response or intolerance to 1 csDMARD.

We hypothesize that intact, cell-free mitochondria from heterogeneous cellular sources are present in the circulation under physiological conditions. Full inclusion and exclusion criteria were reported in the primary publication. However, cellular origins of circulating extracellular mitochondria have not been characterized. Intact cell-free mitochondria have been reported in microparticles (MPs) in murine and human bodily fluids under disease conditions.
