68 Ga‐Labelled Tropane Analogues for the Visualization of the Dopaminergic System

2020

Abstract The development of radiometal‐labelled pharmaceuticals for neuroimaging could offer great potential due to easier handling during labelling and availability through radionuclide generator systems. Nonetheless, to date, no such tracers are available for positron emission tomography, primarily owing to the challenge of crossing the blood–brain barrier (BBB) and loss of affinity through chelator attachment. We have prepared a variety of 68Ga‐labelled phenyltropanes showing that, through a simple hydrocarbon‐linker, it is possible to introduce a chelator onto the lead structure while maintaining its high affinity for hDAT (human dopamine transporter) and simultaneously achieving adequa…

Dopamine, Noradrenaline and Serotonin Receptor Densities in the Striatum of Hemiparkinsonian Rats following Botulinum Neurotoxin-A Injection.

2017

Abstract Parkinson’s disease (PD) is characterized by a degeneration of dopaminergic neurons in the substantia nigra pars compacta (SNpc) that causes a dopamine (DA) deficit in the caudate-putamen (CPu) accompanied by compensatory changes in other neurotransmitter systems. These changes result in severe motor and non-motor symptoms. To disclose the role of various receptor binding sites for DA, noradrenaline, and serotonin in the hemiparkinsonian (hemi-PD) rat model induced by unilateral 6-hydroxydopamine (6-OHDA) injection, the densities of D1, D2/D3, α1, α2, and 5HT2A receptors were longitudinally visualized and measured in the CPu of hemi-PD rats by quantitative in vitro receptor autorad…

LPA1, LPA2, LPA4, and LPA6receptor expression during mouse brain development

2019

Background:LPA is a small bioactive phospholipid that acts as an extracellularsignaling molecule and is involved in cellular processes, including cell prolifera-tion, migration, and differentiation. LPA acts by binding and activating at least sixknown G protein–coupled receptors: LPA1–6. In recent years, LPA has beensuggested to play an important role both in normal neuronal development andunder pathological conditions in the nervous system. Results:We show the expression pattern of LPA receptors during mouse braindevelopment by using qRT-PCR, in situ hybridization, and immunocytochemistry.Only LPA1,LPA2,LPA4,and LPA6 mRNA transcripts were detected throughoutdevelopment stages from embryoni…
