The B7-CD28 family molecules are probably the most intensively studied receptor-ligand systems in the field of immunology. This is evident from the explosive accumulation of literature, particularly in the last ten years. Recent years have witnessed rapid discoveries and characterization of new receptors and ligands in the family. These new pathways, although still in their infancy, have already brought much excitement to the field. However, until now, there has been no single volume to cover this entire area. This book was created to bring together state-of-the-art information and critical...

It is still hard to believe that manipulation of a single protein on the cell surface or an interaction of two or more proteins, which at times is collectively referred to as a pathway, could have such a profound effect on our immune system. At present, a number of such proteins or pathways have been identi?ed. These observations could only be interpreted in a way that, although tens of thousand of proteins are required for a perfectly healthy immune system, many of these pathways may work in either interconnected or linear fashion. Therefore, the combined understanding of each pathway, their...
