Question

Which 4 renal diseases involve IgG, C3?

Answer 1

Four renal diseases that involve IgG and C3 are glomerulonephritis, rheumatoid arthritis, systemic lupus erythematosus, and Goodpasture's syndrome.

Step-by-step explanation:

Four renal diseases that involve IgG and C3 are:

1. Glomerulonephritis: This is the inflammation of the glomeruli in the kidneys and can be caused by immune complexes involving IgG and C3.
2. Rheumatoid arthritis: Although primarily an autoimmune disease affecting the joints, it can also cause kidney involvement where immune complexes form.
3. Systemic lupus erythematosus: This is an autoimmune disease that can affect multiple organs, including the kidneys, where immune complexes containing IgG and C3 can deposit.
4. Goodpasture's syndrome: This is a rare autoimmune disease where antibodies against the glomerular basement membrane, which contain IgG and C3, cause kidney damage.
