The innate immunity protein IFITM3 modulates γ-secretase in Alzheimer's disease

JY Hur, GR Frost, X Wu, C Crump, SJ Pan, E Wong… - Nature, 2020 - nature.com
Innate immunity is associated with Alzheimer’s disease 1 , but the influence of immune
activation on the production of amyloid-β is unknown 2 , 3 . Here we identify interferon-induced …

The role of astrocytes in amyloid production and Alzheimer's disease

GR Frost, YM Li - Open biology, 2017 - royalsocietypublishing.org
Alzheimer's disease (AD) is marked by the presence of extracellular amyloid beta (Aβ) plaques,
intracellular neurofibrillary tangles (NFTs) and gliosis, activated glial cells, in the brain. It …

AD-linked R47H-TREM2 mutation induces disease-enhancing microglial states via AKT hyperactivation

…, M Telpoukhovskaia, TE Tracy, G Frost… - Science translational …, 2021 - science.org
The hemizygous R47H variant of triggering receptor expressed on myeloid cells 2 (TREM2),
a microglia-specific gene in the brain, increases risk for late-onset Alzheimer’s disease (AD)…

[HTML][HTML] Photodynamic therapy–induced immunosuppression in humans is prevented by reducing the rate of light delivery

GA Frost, GM Halliday, DL Damian - Journal of Investigative Dermatology, 2011 - Elsevier
Photodynamic therapy (PDT) of non-melanoma skin cancers currently carries failure rates of
10–40%. The optimal irradiation protocol is as yet unclear. Previous studies showed …

[HTML][HTML] Friend, foe or both? Immune activity in Alzheimer's disease

GR Frost, LA Jonas, YM Li - Frontiers in Aging Neuroscience, 2019 - frontiersin.org
Alzheimer’s disease (AD) is marked by the presence of amyloid beta (Aβ) plaques, neurofibrillary
tangles (NFT), neuronal death and synaptic loss, and inflammation in the brain. AD …

Optical nanosensor for intracellular and intracranial detection of amyloid-beta

M Antman-Passig, E Wong, GR Frost, C Cupo, J Shah… - ACS …, 2022 - ACS Publications
Amyloid-beta (Aβ) deposition occurs in the early stages of Alzheimer’s disease (AD), but the
early detection of Aβ is a persistent challenge. Herein, we engineered a near-infrared …

Hypoxia Inducible Factor-1α binds and activates γ-secretase for Aβ production under hypoxia and cerebral hypoperfusion

C Alexander, T Li, Y Hattori, D Chiu, GR Frost… - Molecular …, 2022 - nature.com
Hypoxic-ischemic injury has been linked with increased risk for developing Alzheimer’s
disease (AD). The underlying mechanism of this association is poorly understood. Here, we …

…, Z Guo, AK Reed, R Kodali, J Borowski, G Frost… - Neuron, 2017 - cell.com
Compelling evidence links amyloid beta (Aβ) peptide accumulation in the brains of Alzheimer's
disease (AD) patients with the emergence of learning and memory deficits, yet a clear …

[HTML][HTML] Hybrid PET/MRI enables high-spatial resolution, quantitative imaging of amyloid plaques in an Alzheimer's disease mouse model

GR Frost, V Longo, T Li, LA Jonas, M Judenhofer… - Scientific reports, 2020 - nature.com
The emergence of PET probes for amyloid plaques and neurofibrillary tangles, hallmarks of
Alzheimer disease (AD), enables monitoring of pathology in AD mouse models. However, …

[HTML][HTML] γ-Secretase modulatory proteins: the guiding hand behind the running scissors

E Wong, GR Frost, YM Li - Frontiers in Aging Neuroscience, 2020 - frontiersin.org
Described as the “proteasome of the membrane” or the “scissors in the membrane,” γ-secretase
has notoriously complicated biology, and even after decades of research, the full extent …
