Healthy human kidneys filter more than 30 gallons of blood each day on average, efficiently removing extra fluid and harmful toxins from the body. If injured, the kidneys have a remarkable capacity for repair. And, yet, in more than one in seven U.S. adults, including disproportionately people with diabetes and hypertension, the daily wear and tear on these vital organs has passed a “tipping point” toward irreparable damage and the onset of chronic kidney disease (CKD) [1].
Defining this tipping point has been a major challenge for a variety of technical reasons. But in a study just published in the journal Science Translational Medicine, researchers have discovered a molecular switch involved in controlling the transition from normal tissue repair to incomplete, or permanent, damage [2]. The NIH-supported researchers also suggest a possible drug candidate to control this switch and slow the progression of CKD.
