Inhibiting effect of foetal renal antigen on leukocyte migration in human glomerulonephritis

In 141 cases of glomerulonephritis confirmed by renal biopsy it was demonstrated that foetal glomerular basement membrane antigen caused a migration inhibition most frequently in minimal change glomerulonephritis. Cellular hypersensitivity was less common in membranous nephropathy, membranoproliferative (I–III) glomerulonephritis, IgA nephropathy and lupus nephritis. The correlation between LMT positivity and the occurrence of renal tissue IF activity was a linear one, but in one type, minimal change glomerulonephritis, there was no such correlation. The occurrence of LMT positivity does not show any considerable difference in glomerulonephritis with and without nephrosis.
