Targeting Podocyte-Endothelial Cell Crosstalk as a FSGS Therapy

NIH-funded research University of Washington · NIH-11332888

What this research studies

As someone with FSGS, you might be asked to provide kidney tissue, blood, or medical data so researchers can study real patient samples. They will use computer analyses of those samples to identify chemical signals sent from podocytes (filter cells) to glomerular endothelial cells (nearby blood-vessel cells). The team will recreate those signals in laboratory cell systems and animal models to see how pathways like cell-aging secretions (SASP) and inflammasome/CASP1 activation damage endothelial cells. Finally, they will test approaches to block the harmful signals and determine whether that prevents or reduces the cell damage linked to worsening FSGS.

Who could benefit from this research

Good fit: Adults diagnosed with focal segmental glomerulosclerosis (FSGS), especially those with biopsy-confirmed disease or ongoing proteinuria, are the most relevant candidates.

Not a fit: Children under 21, people without FSGS, or those with end-stage kidney disease already on dialysis are unlikely to benefit directly from this work.

Why it matters

Potential benefit: If successful, this work could lead to new treatments that slow or prevent kidney scarring and progression to chronic kidney disease in people with FSGS.

How similar studies have performed: Related research supports a role for endothelial injury and inflammasome pathways in kidney disease, but directly targeting podocyte-to-endothelial signaling in FSGS is a relatively new and exploratory approach.
