This subproject is one of many research subprojects utilizing theresources provided by a Center grant funded by NIH/NCRR. The subproject andinvestigator (PI) may have received primary funding from another NIH source,and thus could be represented in other CRISP entries. The institution listed isfor the Center, which is not necessarily the institution for the investigator.This project is designed to develop a radioligand that can be used in PET neuroimaging to quantity estrogen receptor (ER) binding density in brain of monkeys. In conjunction the radiochemistry in Radiology, the ligand, 16a - 18Fluoro-17 -estradiol (18F-FES), was successfully synthesized. Autoradiographic analysis using hypothalamic and pituitary tiissue indicated that FES binding was detected in brain regions known to express ER. PET imaging of the brain and pituitart was initiated in four animals and showed the ligand binding was evident in the hypothalamus, limbic, and cortical areas. This project could lead to new technologies to assess changes in estrdaiol activity associated with neuropathology.
