A primed state exists in vivo following histological regression of amyloidosis.
Using a sensitive, quantitative, and non-invasive in vivo method, based on the specific binding of serum amyloid P component to amyloid fibrils, we have directly documented the spontaneous resolution of AA amyloid deposits in mice, and the prolonged existence thereafter of a primed state of enhanced susceptibility to further amyloid deposition. These results may have important implications for understanding and management of amyloidosis in humans.
