The complement system contributes to kidney damage in IgA nephropathy (IgAN). This review explores complement activation mechanisms and therapeutic inhibition strategies for IgAN progression.
Area of Science:
- Immunology
- Nephrology
- Pathophysiology
Background:
- The complement system is vital for innate immunity but can cause kidney damage when overactivated.
- Immunoglobulin A nephropathy (IgAN) is the most common primary glomerulonephritis, with increasing evidence linking complement pathways to its pathogenesis.
- Complement activation occurs in kidney tissue in IgAN patients, potentially driving glomerular damage and disease progression.
Conclusions:
- Understanding complement activation mechanisms is crucial for elucidating IgAN progression.
- Complement inhibition represents a promising therapeutic avenue for IgAN.
- Further research is needed to fully elucidate the role of complement in IgAN and optimize treatment strategies.
