abstract = {Adenosine A1 receptors (A1ARs) and the interacting
adenosine A2A receptors are implicated in neurological and
psychiatric disorders. Variants within the corresponding
genes ADORA1 and ADORA2A were shown associated with
pathophysiologic alterations, particularly increased
anxiety. It is unknown so far, if these variants might
modulate the A1AR distribution and availability in different
brain regions. In this pilot study, the influence of ADORA1
and ADORA2A variants on in vivo A1AR binding was assessed
with the A1AR-selective positron emission tomography (PET)
radioligand [18F]CPFPX in brains of healthy humans.
Twenty-eight normal control subjects underwent PET
procedures to calculate the binding potential BPND of
[18F]CPFPX in cerebral regions and to assess ADORA1 and
ADORA2A single nucleotide polymorphism (SNP) effects on
regional BPND data. Our results revealed SNPs of both genes
associated with [18F]CPFPX binding to the A1AR. The
strongest effects that withstood even Bonferroni correction
of multiple SNP testing were found in non-smoking subjects
(N=22) for ADORA2A SNPs rs2236624 and rs5751876 (corr.
Pall<0.05). SNP alleles previously identified at risk for
increased anxiety like the rs5751876 T-allele corresponded
to consistently higher A1AR availability in all brain
regions. Our data indicate for the first time that variation
of A1AR availability was associated with ADORA SNPs. The
finding of increased A1AR availability in regions of the
fear network, particularly in ADORA2A risk allele carriers,
strongly warrants evaluation and replication in further
studies including individuals with increased
anxiety.Neuropsychopharmacology advance online publication},
