title: The genetics of the amyloidoses: interactions with immunity and inflammation.
abstract: Historically, the amyloidoses have been associated with inflammation and the immune response. From Virchow's original description in human pathologic inflammatory states through their identification in horses used to produce antitoxin to their frequent occurrence in the course of multiple myeloma and a somewhat abortive designation as 'gammaloid', the disorders were felt to have an inflammatory origin. These presumptive associations antedated the availability of a reliable method for tissue extraction that would allow chemical analysis of the major deposited molecules. With the identification of the multiple precursors and the realization that most were not intrinsic elements of immune/inflammatory pathways, the investigative emphasis shifted to the analysis of the biophysical events involved in aggregation and fibril formation. As more in vivo models and better tools for examination of tissues have become available, it appears as if inflammation may participate as both a response to, and an amplifier of, the effects of the fibrillar aggregates. Hence, while only a limited number of amyloid protein precursors are involved in immunity and inflammation per se, host defense, in its broadest sense, is likely to be involved in the clinically relevant amyloidoses. Further it now appears that harnessing the immune response in an appropriate fashion may be able to play a role in treatment.
