| Research Abstract |
Using leading-edge te chnologies, this study examined new roles of neuronal histamine which have not been fully dissolved. This study was performed on the experiments of molecular and cellular levels and whole animals, and we attempted the results were directly connected to tra nslational human PET studies. Main findings of this study are as follows : 1)The role of C-terminal on H3 receptors-mediated signal transduction were clarified ; 2)The transport of histamine in the CNS was mediated through a newly-identified non-specific t ransporter, PMAT (plasma membrane monoamine transporter)in astrocytes. 3)The existence and roles of H3 receptors in pancreatic islet cells were discovered for the first time. 4)The roles of histamine receptors on whole animals' behavioral levels were ex amined using histamine receptors knockout mice. 5)Brain pharmacokinetics of antihistamines was revealed using molecular PET imaging on the term of H1 receptor occupancy.
