GAL and ovarian carcinoma: It was reported that autologous tumor cell membrane vaccine processed to express α-gal epitopes by incubating ovarian carcinoma membranes prepared from homogenates of freshly obtained tumors with recombinant α1,3GT could successfully induce anti-tumor vaccination via the formation of immune complexes by exploiting the natural anti-Gal Ab and its ligand the α-gal epitope [34].
