The present invention describes a method of administering an Aβ-binding agent or drug which has affinity for amyloid beta (Aβ) in the periphery (blood) and reducing Aβ levels in the brain without the need for the agent or drug to enter the brain itself. The Aβ-binding agents utilized in the methods of the invention are preferably non-immunomodulating agents (e.g., antigenic peptides or antibodies) and bind to Aβ in the periphery, or blood. Such compounds do not significantly cross the blood / brain barrier, and yet they lower amyloid (Aβ) levels in the brain, thereby serving as safer, therapeutic and prophylactic treatments against diseases associated with Aβ in the brain, e.g., Alzheimer's Disease and amyloid angiopathy, as well as against other AD-related amyloidoses.

Administration of human umbilical cord blood cells (HUCBC) or HUCBC-derived plasma is used to treat amyloid-based diseases, such as Alzheimer's disease, Huntington's disease, cerebral amyloid antigopathy, and type-II diabetes. Modulating inflammatory reactions by infusing HUCBC resulted in a marked reduction of amyloid plaques and immune-associated cellular damage. HUCBC infusion also significantly reduced cerebral amyloid angiopathy in mice models. These effects were associated with suppression of the CD40-CD40L interaction and a reduction in surface expressed CD-40 was observed on immune cells. Further, Aβ phagocytic activity was increased and soluble and insoluble Aβ protein levels were modulated by treatment. HUCBC-infused sera also significantly increased phagocytosis of Aβ1-42 peptide and inhibited immune cell CD40 expression and reduced cerebral amyloid angiopathy.
