Plasma dopamine-beta-hydroxylase in depressed patients
Biological Psychiatry
|December 1, 1982
Summary
High plasma dopamine-beta-hydroxylase (DBH) activity may indicate a vulnerability to depression. This enzyme activity was significantly higher in patients with major affective disorder compared to controls.
Area of Science:
- Neuroscience
- Biochemistry
- Psychiatry
Background:
- Plasma dopamine-beta-hydroxylase (DBH) is an enzyme involved in neurotransmitter synthesis.
- Altered DBH activity has been implicated in various psychiatric conditions.
Purpose of the Study:
- To investigate the relationship between plasma DBH activity and major affective disorder.
- To identify potential biomarkers for psychiatric vulnerability.
Main Methods:
- Plasma DBH activity was measured in 28 patients diagnosed with major affective disorder and 34 healthy controls.
- Statistical analyses were performed to compare DBH activity between groups and identify associated factors.
Main Results:
- Patients with major affective disorder exhibited significantly higher plasma DBH activity than controls.
- A higher prevalence of elevated DBH activity (>25 IU) was observed in patients.
- Referred patients showed markedly higher DBH activity compared to those recruited via advertisements.
Conclusions:
- Elevated plasma DBH activity may serve as a vulnerability factor for developing depression.
- DBH activity could be a potential biomarker for affective disorders.
- Further research is warranted to explore the causal mechanisms and clinical implications of these findings.

01:21G-protein Coupled Receptors
G-protein coupled receptors are ligand binding receptors that indirectly affect changes in the cell. The actual receptor is a single polypeptide that transverses the cell membrane seven times creating intracellular and extracellular loops. The extracellular loops create a ligand specific pocket which binds to neurotransmitters or hormones. The intracellular loops holds onto the G-protein.
01:18Depression: Overview
Depression is a prevalent mental illness marked by persistent sadness and lack of interest in previously enjoyable activities. It can take several forms, including major depression, persistent depressive disorder, and bipolar I and II disorders. Symptoms range from emotional changes like chronic worry to physical changes like sleep disturbances and suicidal thoughts. From a neurobiological perspective, depression is believed to be triggered by abnormalities in the brain's prefrontal cortex,...
01:24Parkinson's Disease: Treatment
Neurodegenerative disorders, such as Parkinson's Disease (PD), involve the gradual and irreversible destruction of neurons in particular brain areas. These disorders exhibit standard features like proteinopathies, selective vulnerability of some neurons, and an interaction of intrinsic properties, genetics, and environmental influences in neural injury.

01:24Parkinson Disease ll: Pathophysiology
Parkinson disease (PD) is a progressive neurodegenerative disorder primarily affecting movement, with additional non-motor features. Its pathophysiology involves complex interactions among genetic susceptibility, environmental exposures, and cellular dysfunction, including dopaminergic neuron loss, protein aggregation, and mitochondrial impairment.Selective NeurodegenerationA key feature is the degeneration of dopaminergic neurons in the substantia nigra pars compacta, leading to reduced...
