Differences of Uric Acid Transporters Carrying Extracellular Vesicles in the Urine from Uric Acid and Calcium Stone Formers and Non-Stone Formers

Abstract: Background: Low urine pH and volume are established risk factors for uric acid (UA) stone disease (UASD). Renal tubular epithelial cells exposed to an acidic pH and/or UA crystals can shed extracellular vesicles (EVs) into the tubular fluid, and these EVs may be a pathogenic biomarker of UASD. Methods: Urinary EVs bearing UA transporters (SLC2A9, SLC17A3, SLC22A12, SLC5A8, ABCG2, and ZNF365) were quantified in urine from UA stone formers (UASFs), calcium stone formers (CSFs), and age-/sex-matched non-stone for… Show more

“…In contrast, microvesicles are characterized by the presence of biomarkers like CD40, CD62, and integrin. The unique profiles of these biomarkers in exosomes and microvesicles facilitate their respective roles in intercellular communication, diagnostics, and therapeutic applications [ 16 , 17 ].…”

“…The culmination of this process occurs when MVBs merge with the PM, releasing ILVs as exosomes into the extracellular environment [ 5 , 23 , 24 ]. The orchestration of this intricate process leverages multiple proteins, including the endosomal sorting complexes required for transport (ESCRT), vacuolar ATPase, and Vps4, which are instrumental in segregating ubiquitinated proteins and directing them into ILVs [ 25 , 26 ]. Microvesicles are larger vesicles with dimensions typically spanning 100–1000 nm.…”
