Immunization against the A beta peptide reverses the pathologic and behavioral manifestations of Alzheimer's disease in murine models. Since active immunization is associated with an autoimmune meningoencephalitis in a subset of humans, passive transfer of anti-A beta immunoglobulin is being pursued as a potentially safer alternative. We have identified cases of meningoencephalitis subsequent to peripheral and intracerebral passive immunization of Tg2576 mice. The vasocentric mononuclear infiltrate localized only to brain regions affected by A beta amyloid deposits suggesting that the inflammatory reaction was A beta specific. This report indicates that current passive immunization in humans should proceed with careful regard for autoimmune complications. (c) 2005 Federation of European Biochemical Societies.
