abstract = {Over the last decades adenosine receptor ligands, agonists
as well as antagonists, have been developed. The
requirements for compounds suitable for non-invasivein vivo
imaging of adenosine receptors (radiopharmaceuticals,
radiotracers) with positron emission tomography (PET) are in
several aspects different from thosefor therapeutic drugs.
This difference will be elucidated for radiotracers involved
in human neurotransmission research.In humans theA1
adenosine receptor (A1AR) shows themost abundant
distribution and highest concentrations in brain cortical
and subcortical areas, whereas theA2Aadenosine receptor
(A2AAR) can be found in selected regions like striatum,
nucleus accumbens, olfactory tubercle. A2B adenosine
receptors (A2BAR) and A3 adenosinereceptors (A3ARs) are
expressed in low levels in the brain.Most of the imaging
probes therefore target the A1AR and A2AAR. The talk will
give an overview of currentlyused imaging probes and
applications. The neuroreceptor imaging technique has been
used for example to investigate physiological mechanisms of
the sleep wakeregulation or pathophysiological conditions
like cerebral ischemia, ethanol intoxication, epilepsy or
Alzheimer’s disease in humans and animal models.
Pharmacokineticanalysis of PET experiments allow
additionally to investigate drug action in the human brain,
like for example the impact of caffeine on A1AR
availability.},
