Immune complexes and abnormal liver function in haemophilia. | Abnormal 125I-Clq-binding activity was found in the sera of 94% of 55 haemophiliacs. Sera from 66% of these patients inhibited macrophage uptake of labelled aggregated human IgG in a competitive radiobioassay. These results suggest that large molecular weight immune complexes are present in these sera. Analysis of the ... | 604,359 | [
