A study published in Pediatric Research examines urinary exosomal microRNAs, tiny molecular regulators enclosed within nanoscale particles released by cells, and explores how these signals change after treatment. Urinary exosomal microRNAs could eventually complement existing assessments by offering a minimally invasive way to follow immune and vascular activity over time.
