A mouse model with podocyte-specific Vps34 loss rapidly develops proteinuria, progressive glomerulosclerosis, and mesangial IgA-dominant immune-complex deposition, linking vesicular trafficking defects to glomerular immune changes.
Key Takeaways
- Podocyte-specific Vps34 deletion caused rapid-onset proteinuria from three weeks and median survival of nine weeks.
- Affected mice showed mesangial expansion, glomerulosclerosis, widespread foot process effacement, and complement co-deposition.
- Serum IgA and IgM were elevated while IgG was reduced, coincident with upregulated antigen presentation and inflammasome genes.
