Are elevated serum amyloid A levels and amyloid-enhancing factor sufficient to induce inflammation-associated amyloid deposition?

During inflammation-associated amyloidosis two coincident factors, serum amyloid A (SAA) and amyloid-enhancing factor (AEF) are apparently necessary for amyloid A (AA) deposition. It is shown by passive transfer of cytokines, which stimulate SAA production, and AEF that these are not sufficient. A further factor(s) is necessary, which stems from the acute inflammatory response. Potential candidates are serum or tissue glycosaminoglycans.
