1. Synthesis and evaluation of new PET radioloigands for imaging central norepinephrine transporters
Sammanfattning : The noradrenergic (NE), serotonergic (5-HT) and dopaminergic (DA) neurotransmission systems all have specific proteins responsible for the regulation of synaptic concentrations of neurotransmitter in the central nervous system (CNS) and in the periphery. Several reports have shown that the expression of these proteins, the monoamine transporters, within the CNS, may be altered in patients with certain neurodegenerative or neuropsychiatric disorders.

2. Development of radioligands for the serotonergic neurotransmission system for use in positron emission tomography
Sammanfattning : The serotonergic system is implicated in several neuropsychiatric disorders, such as depression, anxiety and schizophrenia. Several hypotheses on the pathophysiology of these disorders are based on the pharmacology of serotonergic drugs. Selective serotonin reuptake inhibitors (SSRIs) are widely used for the treatment of depression and anxiety. LÄS MER
3. Development of positron emission tomography radioligands for the dopaminergic and serotonergic neurotransmission systems
Sammanfattning : The dopaminergic and serotonergic neurotransmission systems are of central interest in relation to several neuropsychiatric disorders. The main objectives were to develop new suitable radioligands for positron emission tomography (PET) examinations of the dopamine transporter (DAT) as well as the serotonin 5-HT1A and 5-HT2A-receptors.

4. Catecholaminergic neurotransmission in heart and brain : development of tracers for positron emission tomography
Sammanfattning : The catecholamines norepinephrine and its biosynthetic precursor dopamine are two principal neurotransmitters in the human central nervous system (CNS). Moreover, norepinephrine is a major transmitter substance in the peripheral, autonomic nervous system. LÄS MER
5. Dopamine D2 receptor G protein coupling and it's regulation
Sammanfattning : Dopamine (DA) receptors belong to the superfamily of G protein coupled receptors. The D2 DA receptor is negatively coupled with adenylate cyclase via pertussis toxin sensitive (Gi/o) G proteins. LÄS MER
