Basic Principles of Antigen-Antibody Interaction

Abstract

The immune system may be viewed as the locus of a multitude of molecular interactions involving a limited number of genetically determined structures. Most of these structures act as membrane receptors (i.e., communication organs of cells) or as secreted factors. These are called antibodies (Ab), T cell receptors, or class I and II molecules coded for in the major histocompatibility complex (MHC).
