Abstract
Alzheimer's disease is treated by attacking hyperactive microglia preferably before excessive beta amyloid is built up by administering tin-117m-DOTA annexin V. This compound in low radioactive doses selectively binds to the aged hyperactive microglia and emits a conversion electron which effectively induces apoptosis in the hyperactive microglia. A follow-up treatment of tin-annexin A1 can be administered to repair the blood brain barrier. The annexin A1 assists in the repair of the blood-brain barrier and the associated tin-117m will induce apoptosis in aged hyperactive microglia associated with the blood brain barrier.
Claims5
A method of detecting microglia having exposed phosphatidyl serine comprising administering to a patient annexin V labeled with a detectable radionuclide at a dose sufficient to bind to exposed phosphatidyl serine on the microglia in said patient's brain and noninvasively detecting said radionuclide bound to exposed phosphatidyl serine on the microglia in the brain of said patient, wherein the radionuclide is tin-117m having a specific activity between 500 Ci/g and 25,000 Ci/g at the end of bombardment.
