1. Dopamine D2 and D3 receptors. Studies on transduction mechanisms and on the role of a D3 gene polymorphism
Sammanfattning : The neurotransmitter dopamine has been implicated in the pathophysiology of, e.g., Parkinson s disease and schizophrenia, and dopamine receptor-active compounds are commonly employed therapeutically in these and other disorders. LÄS MER
2. Ethanol-induced modulation of dopamine transmission and synaptic activity in striatal subregions - focus on inhibitory receptors
Sammanfattning : Background: Alcoholism is a chronic brain disease, affecting neurocircuitries involved in reward and learning. The rewarding effects of alcohol (ethanol) are believed to result from increased dopamine levels in the nucleus accumbens (nAc) via the mesolimbic system. LÄS MER
3. Nuclear medicine methods in idiopathic Parkinsonism : pre- and postsynaptic dopamine SPECT
Sammanfattning : Background: Single photon emission computed tomography (SPECT) with dopamine transporter (DAT) and dopamine D2 receptor (D2R) ligands can visualise the integrity of the nigrostriatal dopamine system. Parkinson’s disease (PD) and the atypical parkinsonian diseases (APD), progressive supranuclear palsy (PSP) and multiple system atrophy (MSA), have similar symptoms and dopamine depletion, but differ in pharmacological response and prognosis.

4. Striatal pathways in dyskinesia and dystonia
Sammanfattning : Purposeful and well-coordinated movements depend on the control exerted by dopamine (DA) on the basal ganglia (BG) network. Accordingly, dysfunctions or lesions of the dopaminergic system in the BG can result in an overall poverty and slowness of movement, cardinal features of Parkinson´s disease (PD), or in dyskinesias, exaggerated and involuntary movements resulting from L-DOPA pharmacotherapy.

5. Pharmacological and genetic manipulation of adipose cell differentiation and metabolism
Sammanfattning : Adipose tissue dysfunction has a pivotal role in the development of obesity and related metabolic complications, such as insulin resistance, cardiovascular disease, and diabetes. The overall aim was to study the consequences of adipose exposure to pharmacological agents, as well as dysregulations in the expression of genes, potentially involved in adipose tissue dysfunction and related metabolic impairments.
