abstract = {Adenosine, its interacting A1 and A2A receptors, and
particularly the variant rs5751876 in the A2A gene ADORA2A
have been shown to modulate anxiety, arousal, and sleep. In
a pilot positron emission tomography (PET) study in healthy
male subjects, we suggested an effect of rs5751876 on in
vivo brain A1 receptor (A1AR) availability. As female sex
and adenosinergic/dopaminergic interaction partners might
have an impact on this rs5751876 effect on A1AR
availability, we aimed to (1) further investigate the pilot
male-based findings in an independent, newly recruited
cohort including women and (2) analyze potential modulation
of this rs5751876 effect by additional
adenosinergic/dopaminergic gene variation. Healthy
volunteers (32/11 males/females) underwent phenotypic
characterization including self-reported sleep and
A1AR-specific quantitative PET. Rs5751876 and 31 gene
variants of adenosine A1,A2A,A2B, and A3 receptors,
adenosine deaminase, and dopamine D2 receptor were
genotyped. Multivariate analysis revealed an rs5751876
effect on A1AR availability (P=0.047), post hoc confirmed
in 30 of 31 brain regions (false discovery rate (FDR)
corrected P values<0.05), but statistically stronger in
anxiety-related regions (e.g., amygdala, hippocampus).
Additional effects of ADORA1 rs1874142 were identified;
under its influence rs5751876 and rs5751876 × sleep had
strengthened effects on A1AR availability (Pboth <0.02; post
hoc FDR-corrected Ps<0.05 for 29/30 regions, respectively).
Our results support the relationship between rs5751876 and
A1AR availability. Additional impact of rs1874142, together
with rs5751876 and sleep, might be involved in regulating
arousal and thus the development of mental disorders like
anxiety disorders. The interplay of further detected
suggestive ADORA2A × DRD2 interaction, however,
necessitates larger future samples more comparable to
magnetic resonance imaging (MRI)-based samples.},
