Antibodies are crucial to the fine specificity of the immune system. An effective functioning of these molecules requires interaction with immune cells. Receptors for antibodies, Fc receptors, provide this critical link between the humoral and cellular branches of the immune system. This book presents a comprehensive overview of the different Fc receptors currently recognized. The first part of the book contains state-of-the-art overviews on the biological role of FcR. The latest information on FcR heterogeneity, FcR physiology, FcR-ligand recognition, their crucial coordinating role...
