Platelets Used as a Serotonin Neuron Model
In Studies of Major Depression
• Lots of serotonin-related abnormalities.
• Serotonin uptake low.
• Serotonin transporter sites are fewer.
• More 5-HT2A receptors in association with suicidal acts.
• 5-HT2A signal transduction is blunted in suicidal cases.
• Possible link to increased risk of death from myocardial
infarction in major depression.
