Idiopathic paraproteinaemia. I. Studies in an animal model--the ageing C57BL/KaLwRij mouse.
A search for a suitable animal model for studies on idiopathic paraproteinaemia showed that an age-dependent increase in the appearance of homogeneous immunoglobulins in serum was common to all of the seven mouse strains investigated to date. The highest frequency was found in C57Bl/KaLwRij mice. Further investigations in this strain demonstrated that, except for some quantitative differences, most of the features of human and C57BL Mouse idiopathic paraproteinaemia were essentially the same. No clear-cut correlation was found between the idiopathic paraproteinaemia and, in the old C57B1 mice, a rather frequently occurring reticulum cell sarcoma B and amyloidosis. The mouse idiopathic paraproteinaemia can be regarded as an analogue of the human idiopathic paraproteinaemia and therefore as a suitable model for further experimental studies.
