Chronic kidney disease affects many people and is a growing health problem. One serious form is antibody-mediated glomerulonephritis, called AGN. In AGN, the immune system makes antibodies that attack the kidney filters and cause inflammation and injury.
A research team used a mouse model to watch the inflammatory process inside the kidney. They focused on immune cells called neutrophils and found that these cells increase a glucose transporter called Glut1. Glut1 moves glucose into cells and helps cells use energy.
The researchers then disabled Glut1 in neutrophils and saw less tissue damage. They also treated mice with a Glut1 inhibitor and found improved kidney pathology. The study was led by a university research team.
