We also found that downstream pre-synaptic dopamine D1 Receptor binding correlated with dopamine loss in Lewy body disease groups, and RNA damage and β-site APP cleaving enzyme 1 in the caudate of AD.
Our data reveal a mechanism of hippocampal vulnerability in AD and suggest that a combined activation of GHSR1α and DRD1 may be a promising approach for treating AD.
Here we measured by quantitative real-time PCR the mRNA levels of SST/CST, their receptors (sst1-5 and DA receptors (drd1-5) in addition to neprilysin (a SST-regulated enzyme involved in Abeta degradation) in three regions of the temporal lobe, one of the cortical regions most severely affected by AD.
