abstract = {The accumulation of tau is a hallmark of several
neurodegenerative diseases and is associatedwith neuronal
hypoactivity and presynaptic dysfunction. Oral
administration of the adenosineA1 receptor antagonist
rolofylline (KW-3902) has previously been shown to reverse
spatial memorydeficits and to normalize the basic synaptic
transmission in a mouse line expressing
full-lengthpro-aggregant tau (TauDK) at low levels, with
late onset of disease. However, the efficacy of
treatmentremained to be explored for cases of more
aggressive tauopathy. Using a combination of
behavioralassays, imaging with several PET-tracers, and
analysis of brain tissue, we compared the curativereversal
of tau pathology by blocking adenosine A1 receptors in three
mouse models expressingdifferent types and levels of tau and
tau mutants. We show through positron emission
tomographyusing the tracer [18F]CPFPX (a selective A1
receptor ligand) that intravenous injection of
rolofyllineeffectively blocks A1 receptors in the brain.
Moreover, when administered to TauDK mice, rolofyllinecan
reverse tau pathology and synaptic decay. The beneficial
effects are also observed in a line withmore aggressive tau
pathology, expressing the amyloidogenic repeat domain of tau
(TauRDDK) withhigher aggregation propensity. Both models
develop a progressive tau pathology with
missorting,phosphorylation, accumulation of tau, loss of
synapses, and cognitive decline. TauRDDK causespronounced
neurofibrillary tangle assembly concomitant with neuronal
death, whereas TauDK accumulatesonly to tau pretangles
without overt neuronal loss. A third model tested, the
rTg4510line, has a high expression of mutant TauP301L and
hence a very aggressive phenotype starting at~3 months of
age. This line failed to reverse pathology upon rolofylline
treatment, consistent with ahigher accumulation of
tau-specific PET tracers and inflammation. In conclusion,
blocking adenosineA1 receptors by rolofylline can reverse
pathology if the pathological potential of tau remains below
athreshold value that depends on concentration and
aggregation propensity.},
