RADIOLABELED ETHER DENDRIMER CONJUGATES FOR PET IMAGING AND RADIOTHERAPY
Compositions and methods for detecting, monitoring and imaging inflammatory sites or tumors in a subject have been developed. Compositions of hydroxyl-terminated dendrimers conjugated to radionuclide(s) via ether linkages are provided for both imaging and radiotherapy (tumors). Methods for the non-invasive and specific positron emission tomography (PET) imaging or magnetic resonance imaging (MRI) of dendrimer conjugated to one or more imaging agents in a subject in vivo are also provided. The methods selectively deliver dendrimer conjugated to radionuclides or MRI contrast agents to reactive microglia or reactive immune cells in tumors in the recipient. In some embodiments, the dendrimers conjugated to imaging agents also deliver targeted radiotherapy agents to a tumor, and/or deliver additional diagnostic, therapeutic or prophylactic agents to reactive microglia in the recipient. Methods of making dendrimers conjugated to imaging agents are also described..
