Abstract

Antibodies of the horse were studied intensively by many notable immunologists throughout the past century until the early 1970's. After a large gap of interest in horse immunology, additional basic studies on horse immunoglobulin genes performed during the past 10 years have resulted in new insights into the equine humoral immune system. These include the characterization of the immunoglobulin lambda and kappa light chain genes, the immunoglobulin heavy chain constant (IGHC) gene regions, and initial studies regarding the heavy chain variable genes. Horses express predominately lambda light chains and seem to have a relatively restricted germline repertoire of both lambda and kappa chain variable genes. The IGHC region contains eleven constant heavy chain genes, seven of which are gamma heavy chain genes. It is suggested that all seven genes encoding IgG isotypes are expressed and have distinct functions in equine immune responses.
