Neurobiol Dis 14:10-8. 2003..Most of the Abeta in the serum of the immunized mice was bound to antibodies. We conclude that following active immunization, anti-Abeta antibodies sequester serum Abeta and may increase central nervous system to serum Abeta clearance... - Matrix metalloproteinase-9 and spontaneous hemorrhage in an animal model of cerebral amyloid angiopathyJin Moo Lee
