Glomerular Filters in the Kidney (IMAGE) Michigan Medicine - University of Michigan Caption These tiny structures inside the kidney, called glomerular filters, suffer damage from diabetes and grow less effective at filtering the blood. The basic research that led to the clinical trial found that a cell-signaling pathway inside these structures could be a drug target -- and an existing drug being developed for arthritis already targeted that pathway.
