Glomerulonephritis: immunopathogenesis and immunotherapy

Area of Science:

• Nephrology
• Immunology
• Pathology

Background:

• Glomerulonephritis (GN) encompasses diverse immune-mediated kidney diseases.
• Current classification by histopathology doesn't reflect underlying mechanisms or guide therapy effectively.

Purpose of the Study:

• To propose a novel classification of GN based on immunopathogenesis.
• To align GN categorization with distinct pathological mechanisms for improved therapeutic targeting.

Main Methods:

• Reviewing the immunopathogenesis of various GN types.
• Proposing a five-category classification: infection-related, autoimmune, alloimmune, autoinflammatory, and monoclonal gammopathy-related GN.

Main Results:

• The proposed classification links specific immunopathogenic pathways to targeted therapies.
• Examples include infection control for infection-related GN and B cell therapy for monoclonal gammopathies.

Conclusions:

• An immunopathogenesis-based classification offers a more precise framework for understanding and managing GN.
• This approach can enhance research focus, clinical management, and medical education in nephrology.
