It has been 15 years since the first report on the isolation of anti-Gal from human serum and the demonstration that this antibody is the most prevalent antibody in humans (Galili et al. , ]. Exp. Med. 160: 1519, 1984). Subsequent interdisciplinary studies in immunology, carbohydrate biochemistry, molecular biology, and evo- lution demonstrated the highly restricted specificity of anti-Gal for the carbohy- drate epitope Gal al-3Galpl-4GIcNAc-R, (termed here the a-gal epitope), the unprecedented evolutionary pattern of distribution of a-gal and anti-Gal in mam- mals, and explained the evolution of this antigen and antibody by analysis of the a 1 ,3galactosyltransferase gene, the gene that encodes the enzyme that synthesizes the a-gal epitope. These studies have suggested that a major selection process that occurred in the course of evolution of ancestral Old World primates resulted in the inactivation of the a1 ,3galactosyltransferase gene and the subsequent appearance of anti-Gal in these primates. Other studies in immunoparasitology have demon- strated the possible physiologic significance of anti-Gal in protection against cer- tain parasitic infections.Major scientific attention was focused on a-gal and anti-Gal with the real- ization in the early nineties that the interaction between this antigen and antibody is the major obstacle to xenotransplantation. The success of immunosuppressive drugs, in the last two decades of the 20th century, in preventing allograft rejection, has raised hopes for cure in many patients in need of organ transplant. Because of limited supply of allografts, only 20% of patients receive the needed organ.

Volume 18 of the Subcellular Biochemistry series, which specializes in various aspects of the biochemistry of the intracellular parasites, was initially proposed by Jose Luis Avila and strongly supported by myself, as Series Editor of Sub cellular Biochemistry. Considerable assistance was received from Professor Frank Wunderlich (University of Dusseldorf) and more particularly from Dr. Michael Miles (London School of Hygiene and Tropical Medicine) during the compilation of the list of possible chapters. Our initial aim was to present a comprehensive survey of this broad field of study. Although some interesting topics have been lost due to authors backing out late in the production schedule of the book, the manuscripts that were submitted have provided a useful over view of the subject, with notable strength within the field of Leishmania. The 13 chapters of the book have been grouped according to subject. The first five chapters deal with Leishmania and are followed by two chapters on Try ponosoma cruzi, two on the malarial parasites, and two on the Coccidia. The fmal two chapters cover the Microsporidia and chemotherapy, respectively.
