    Variants in the MS4A cluster interact with soluble TREM2 expression on biomarkers of neuropathology

    Recent evidence suggests that Alzheimer’s disease (AD) genetic risk variants (rs1582763 and rs6591561) of the MS4A locus are genome-wide significant regulators of soluble TREM2 levels such that the minor allele o...

    TREM2 gene expression associations with Alzheimer’s disease neuropathology are region-specific: implications for cortical versus subcortical microglia

    Previous post-mortem assessments of TREM2 expression and its association with brain pathologies have been limited by sample size. This study sought to correlate region-specific TREM2 mRNA expression with diverse ...

    Large multi-ethnic genetic analyses of amyloid imaging identify new genes for Alzheimer disease

    Amyloid PET imaging has been crucial for detecting the accumulation of amyloid beta (Aβ) deposits in the brain and to study Alzheimer’s disease (AD). We performed a genome-wide association study on the largest...

    Alzheimer’s disease genetic risk and cognitive reserve in relationship to long-term cognitive trajectories among cognitively normal individuals

    Both Alzheimer’s disease (AD) genetic risk factors and indices of cognitive reserve (CR) influence risk of cognitive decline, but it remains unclear whether they interact. This study examined whether a CR inde...

    Protective genes and pathways in Alzheimer’s disease: moving towards precision interventions

    Alzheimer’s disease (AD) is a progressive, neurodegenerative disorder that is characterized by neurodegeneration, cognitive impairment, and an eventual inability to perform daily tasks. The etiology of Alzheim...

    Brain expression of the vascular endothelial growth factor gene family in cognitive aging and alzheimer’s disease

    Vascular endothelial growth factor (VEGF) is associated with the clinical manifestation of Alzheimer’s disease (AD). However, the role of the VEGF gene family in neuroprotection is complex due to the number of...

    Genome-wide meta-analysis identifies new loci and functional pathways influencing Alzheimer’s disease risk

    Alzheimer’s disease (AD) is highly heritable and recent studies have identified over 20 disease-associated genomic loci. Yet these only explain a small proportion of the genetic variance, indicating that undis...
