Amyloidosis development in LLC mice.

Using electron microscopy and the protein A-gold labelling technique we studied amyloidosis in the LLC mice, an inbred strain developing amyloidosis spontaneously. We found that the reticular cells lining around the sinuses in the red pulp of the spleen were converted to amyloid. Evidence suggests that the amyloid originates in the cells themselves. The process of amyloid formation is discussed.
