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.To assess in vivo maternal-fetal transport of putative neurotoxins using PET imaging.We used PET-CT imaging to study maternal-fetal transport of materials in one preliminary study involving a pregnant rhesus macaque of the WNPRC breeding colony. The goal of this study was to assess the in vivo transport from the mother to the fetus of a dopamine receptor tracer. We observed rapid transport and specific uptake and retention of the tracer in the fetal striatum, which is rich with dopamine receptors. This study demonstrates the feasibility of this non-invasive technique. We plan future work pending the funding of a grant proposal submitted to the NIH.
We aim to assess fetal uptake of environmental neurotoxins in order to make science-based risk assessment of neurotoxin exposure in utero. This research used Animal Services.
