Osaka researchers catch an autoimmune kidney disease at its very first step — and stop it

In ANCA-associated glomerulonephritis, the immune system attacks the kidneys' tiny filters, often before anyone knows something is wrong. Researchers led by Masayuki Nishide and Atsushi Kumanogoh at the University of Osaka have now mapped how the damage begins: injured kidney cells call in neutrophils — front-line immune cells — which gather into harmful clusters and spread the inflammation. In a mouse model, published in the Journal of Experimental Medicine, modified antibodies that calmed the neutrophils' activation curbed the kidney injury. It is early, animal-stage work, but it points to treating the disease at its first step instead of after severe damage is done.
