Reduction in glomerular heparan sulfate correlates with complement deposition and albuminuria in active Heymann nephritis.

In a time-study of active Heymann nephritis, the expression of agrin, the main heparan sulfate proteoglycan in the glomerular basement membrane, was analyzed in relation to deposition of IgG and complement in the glomerular capillary wall and the development of albuminuria. Binding of IgG autoantibodies to the glomerular capillary wall could be detected… CONTINUE READING
