Abstrakt: Higher serotonin-1A (5-HT 1A ) receptor binding potential (BP F ) has been found in major depressive disorder (MDD) during and between major depressive episodes. We investigated whether higher 5-HT 1A binding is a biologic trait transmitted to healthy high risk (HR) offspring of MDD probands. Data were collected contemporaneously from: nine HR, 30 depressed not-recently medicated (NRM) MDD, 18 remitted NRM MDD, 51 healthy volunteer (HV) subjects. Subjects underwent positron emission tomography (PET) using [ 11 C]WAY100635 to quantify 5-HT 1A BP F , estimated using metabolite, free fraction-corrected arterial input function and cerebellar white matter as reference region. Multivoxel pattern analyses (MVPA) of PET data evaluated group status classification of individuals. When tested across 13 regions of interest, an effect of diagnosis is found on BP F which remains significant after correction for sex, age, injected mass and dose: HR have higher BP F than HV (84.3% higher in midbrain raphe, 40.8% higher in hippocampus, mean BP F across all 13 brain regions is 49.9% ± 11.8% higher). Voxel-level BP F maps distinguish HR vs. HV. Elevated 5-HT 1A BP F appears to be a familially transmitted trait abnormality. Future studies are needed to replicate this finding in a larger cohort and demonstrate the link to the familial transmission of mood disorders.
