Abstract

PURPOSE: The purpose of this study was to assess, in a large sample of healthy young adults, sex differences in the binding potential of [11C]ABP688, a positron emission tomography (PET) tracer selective for the metabotropic glutamate type 5 (mGlu5) receptor.

METHODS: High resolution [11C]ABP688 PET scans were acquired in 74 healthy volunteers (25 male, 49 female, mean age 20?±?3.0). Mean binding potential (BPND?=?fND * (Bavail / KD)) values were calculated in the prefrontal cortex, striatum, and limbic regions using the simplified reference tissue model with cerebellar grey matter as the reference region.

RESULTS: [11C]ABP688 BPND was significantly higher in men compared to women in the prefrontal cortex (p?<?0.01), striatum (p?<?0.001), and hippocampus (p?<?0.05). Whole-brain BPND was 17% higher in men. BPND was not related to menstrual phase in women.

CONCLUSIONS: Binding availability of mGlu5 receptors as measured by PET [11C]ABP688 is higher in healthy men than women. This likely represents a source of variability in [11C]ABP688 studies and could have relevance for sex differences in cognitive-behavioral functions and neuropsychiatric disorders.
