complement 4 nephritic factor

12/01/2012 - "Previous patients with C4 nephritic factor had membranoproliferative glomerulonephritis. "
03/27/1990 - "C4NeF activity was measured, using the ELISA method, in patients with various glomerular diseases, and found elevated in three of 24 patients with membranoproliferative glomerulonephritis (MPGN) type I and slightly but distinctly positive in seven of 24. "

02/01/1987 - "C4 nephritic factor in a patient with chronic glomerulonephritis."
02/01/1987 - "C4 nephritic factor (C4NeF) was found in the serum of a patient with chronic glomerulonephritis, whose C3 level was quite low (less than 1% of normal). "
07/01/1981 - "A fourth mechanism described here is based on the observation that the IgG fraction of the serum of certain patients with glomerulonephritis contains a protein termed C4 nephritic factor (NFc), which prevents the intrinsic decay of C4b2a. "
01/01/1988 - "Nephritic factor of the classical complement pathway (C4NeF) is an IgG antibody which stabilizes the C3 convertase (C4b2a) and has been detected in sera from patients with systemic lupus erythematosus (SLE) and acute postinfectious glomerulonephritis. "

03/27/1990 - "No C4NeF was detected in two C3 nephritic factor-positive patients with MPGN type II and six with active systemic lupus erythematosus. "
01/01/1988 - "Nephritic factor of the classical complement pathway (C4NeF) is an IgG antibody which stabilizes the C3 convertase (C4b2a) and has been detected in sera from patients with systemic lupus erythematosus (SLE) and acute postinfectious glomerulonephritis. "
