title: Lymphocytotoxins and mixed leucocyte culture blocking factor activity in the plasma of uraemic patients undergoing haemodialysis.
abstract: Mixed leucocyte culture blocking factor activity (MLC-BFA) in the plasma of haemodialysis patients appears as a result of recent blood transfusions and is concentrated in IgG fractions of the blocking serum. Four patients neither developed lymphocytotoxins nor MLC-BFA in spite of having received multiple blood transfusions. Such 'unresponsive' recipients had an excellent clinical course upon receiving an allograft.
