Dr. Kennedy’s research program has been funded by the Canadian Institutes for Health Research (CIHR), the Kidney Foundation of Canada (KFOC), and the Canada Foundation for Innovation. He was a CIHR New Investigator Scholar. He has held CIHR operating grants continuously since 2001, seeking to identify factors such as prostaglandins and reactive oxygen species responsible for mediating damage to cells within the kidney’s filtration barrier – known as podocytes. Such injury results in abnormal leakage of protein into the urine. Identifying the specific factors responsible for filtration barrier injury may reveal a novel therapeutic target for the prevention of glomerular diseases. Most recently, his work defined a critical role for a novel NADPH oxidase isoform (Nox5) in diabetic kidney disease. Dr. Kennedy’s KFOC-funded research has shed light on how mutations in the alpha-actinin-4 gene lead to an inherited form of a common kidney disease - focal segmental glomerulosclerosis (FSGS). This research project employs transgenic technology to reproduce this disease state in mice so that its progression can be better studied and novel therapies developed.
