[Evolution of antibodies and ABH plasmatic transferases in transplants with ABH difference between the recipient and...

Another important aspect of these transplants is the possibility of assessing the variations in the activity of serum ABH transferases in receptors of organs with ABH typing different from theirs. The antigenicity of these enzymes has been proven, antitransferase antibodies being found in BMT with minor mismatch, A-group receptors of O-group bone-marrow, and in SOT with major mismatch, O-group receptors of B-group liver. The study of the properties of such antibodies is of great interest in the course of GVHD or HVGD, in either form of transplant, as well as in the knowledge of the biochemical and immunologic characteristics of these ABH enzymes.
