THK5351 12-19 microtubule associated protein tau Homo sapiens 72-99 31834916-11 2019 Hippocampal atrophy was associated with both beta-amyloid and THK-5351 uptake, possibly reflecting an interaction between beta-amyloid and tau deposition in the neurodegeneration process. THK5351 62-70 microtubule associated protein tau Homo sapiens 139-142 31464590-2 2019 Recent data support the hypothesis that THK5351 binds to monoamine oxidase B (MAO-B) expressed from reactive astrocytes and that flortaucipir has an affinity toward MAO-A and B; however, pathological evidence is lacking. THK5351 40-47 monoamine oxidase B Homo sapiens 57-76 31464590-2 2019 Recent data support the hypothesis that THK5351 binds to monoamine oxidase B (MAO-B) expressed from reactive astrocytes and that flortaucipir has an affinity toward MAO-A and B; however, pathological evidence is lacking. THK5351 40-47 monoamine oxidase B Homo sapiens 78-83 31464590-10 2019 CONCLUSIONS: Our findings add pathological evidence that increased THK5351 uptake in sporadic CJD patients might be caused by an off-target binding driven by its high affinity for MAO-B. THK5351 67-74 monoamine oxidase B Homo sapiens 180-185 29143870-2 2018 Recently, tau positron emission tomography tracers such as [18F] AV-1451 and [18F] THK5351 have been developed to detect tau deposition in vivo. THK5351 83-90 microtubule associated protein tau Homo sapiens 10-13 31795034-0 2019 Rasagiline, a monoamine oxidase B inhibitor, reduces in vivo [18F]THK5351 uptake in progressive supranuclear palsy. THK5351 66-73 monoamine oxidase B Homo sapiens 14-33 31795034-2 2019 However, the interpretation of [18F]THK5351 uptake has been shown to be confounded by high monoamine oxidase B (MAO-B) availability across the brain in AD. THK5351 36-43 monoamine oxidase B Homo sapiens 91-110 31795034-2 2019 However, the interpretation of [18F]THK5351 uptake has been shown to be confounded by high monoamine oxidase B (MAO-B) availability across the brain in AD. THK5351 36-43 monoamine oxidase B Homo sapiens 112-117 31795034-9 2019 CONCLUSIONS: Similar to AD, the interpretation of [18F]THK5351 uptake in PSP is likely confounded by off-target binding to MAO-B binding sites. THK5351 55-62 monoamine oxidase B Homo sapiens 123-128 29958546-6 2018 Regional [18F]THK5351 standardized uptake value ratio (SUVR) in antemortem PET was significantly correlated with monoamine oxidase-B (MAO-B) level, reactive astrocytes density, and tau pathology at postmortem examination. THK5351 14-21 monoamine oxidase B Homo sapiens 113-132 29958546-6 2018 Regional [18F]THK5351 standardized uptake value ratio (SUVR) in antemortem PET was significantly correlated with monoamine oxidase-B (MAO-B) level, reactive astrocytes density, and tau pathology at postmortem examination. THK5351 14-21 monoamine oxidase B Homo sapiens 134-139 29958546-6 2018 Regional [18F]THK5351 standardized uptake value ratio (SUVR) in antemortem PET was significantly correlated with monoamine oxidase-B (MAO-B) level, reactive astrocytes density, and tau pathology at postmortem examination.

THK5351 38-45 monoamine oxidase B Homo sapiens 178-183 29958546-8 2018 In conclusion, [18F]THK5351 PET signals reflect MAO-B expressing reactive astrocytes, which may be associated with tau accumulation in PSP. THK5351 20-27 monoamine oxidase B Homo sapiens 48-53 29958546-8 2018 In conclusion, [18F]THK5351 PET signals reflect MAO-B expressing reactive astrocytes, which may be associated with tau accumulation in PSP. THK5351 20-27 microtubule associated protein tau Homo sapiens 115-118 28864633-4 2018 Results: Regional in vivo 18F-THK5351 retention was significantly correlated with the density of tau aggregates in the neocortex and monoamine oxidase-B in the whole brain, but not correlated with that of insoluble amyloid-beta. THK5351 30-37 microtubule associated protein tau Homo sapiens 97-100 28864633-4 2018 Results: Regional in vivo 18F-THK5351 retention was significantly correlated with the density of tau aggregates in the neocortex and monoamine oxidase-B in the whole brain, but not correlated with that of insoluble amyloid-beta.
