Beyond Monoamines: The Role of the Nociceptin/Orphanin FQ Receptor in Major Depression
Study Details
Study Description
Brief Summary
This study looks at the role of the Nociceptin/Orphanin FQ receptor system in the brain of individuals with current or past major depressive disorder (MDD). It also examines how individuals with a history of depression make certain decisions and which brain regions are involved in such decisions. Information collected through MRI, PET, biospecimens (i.e., blood, saliva) and behavioral tasks will be used to predict depressive symptoms in the future.

Detailed Description
The overarching goals of this research are to investigate: (1) the activity of the Nociceptin/Orphanin FQ receptor system among individuals with current or remitted MDD; (2) neural foundations of approach/avoidance behaviors in current or remitted MDDs; (3) stress-induced inflammation in individuals with remitted MDD; (4) neural markers that predict future disease course.
This will be achieved through an innovative method of using functional magnetic resonance imaging (fMRI) during an approach/avoidance decision-making task, in addition to a resting positron emission tomography (PET) scan.
Study Design
Arms and Interventions
Arm | Intervention/Treatment |
---|---|
MDD subjects Subjects diagnosed with Major Depression Disorder |
Device: Aversive stimuli
Electrotactile stimulation will be used as the aversive stimulus. The aversive stimulus is delivered in the form of a mild half-second stimulation to the ankle, calibrated to a subjective threshold that is uncomfortable but not painful. This stimulation is delivered by Digitimer DS8R Constant Current Stimulator (Digitimer North America, LLC. Ft. Lauderdale, FL). Its previous model DS71 has been safely implemented in studies with previously MGH-approved IRB's (Milad et al., 2013).
Drug: PET radiotracer
A Nociceptin/Orphanin FQ ("N/OFQ") peptide tracer ([11C] NOP-1A) will be used as the PET radiotracer. Approximately 10 mCi of this tracer will be delivered intravenously as a slow bolus over 60 seconds with beginning of the PET imaging acquisition. Approximately 60 ml of blood will be drawn from an artery throughout the dynamic PET acquisition in order to measure the blood N/OFQ levels.
