Increased phosphatidylserine-exposing microparticles and their originating cells are associated with the coagulation process in patients with IgA nephropathy.
Relatively little information is available about phosphatidylserine positive (PS(+)) microparticles (MPs) and their originating cells in IgA nephropathy (IgAN) despite well-established intraglomerular coagulation. Our objectives were to detect PS exposure on MP membranes and MP-origin cells and to evaluate its role in procoagulant activity (PCA) and fibrin formation and their association with pathological lesions in the disease. ⋯ We find that high levels of PS(+) MPs and the MP-origin cells are associated with the coagulation process in IgAN, and this may provide a previously unrecognized contribution to intraglomerular coagulation.
