Clinical and biochemical correlates of insoluble α-synuclein in dementia with Lewy bodies
α-Synuclein is a major constituent of Lewy bodies, the fibrillar aggregates that form within neurons in Parkinson’s disease and dementia with Lewy bodies (DLB). Recent biochemical data show that α-synuclein ac...

No alteration in tau exon 10 alternative splicing in tangle-bearing neurons of the Alzheimer’s disease brain
Defective splicing of tau mRNA, promoting a shift between tau isoforms with (4R tau) and without (3R tau) exon 10, is believed to be a pathological consequence of certain tau mutations causing frontotemporal d...

Association study of cholesterol-related genes in Alzheimer’s disease
Alzheimer’s disease (AD) is a genetically complex disorder, and several genes related to cholesterol metabolism have been reported to contribute to AD risk. To identify further AD susceptibility genes, we have...

Increase in the relative expression of tau with four microtubule binding repeat regions in frontotemporal lobar degeneration and progressive supranuclear palsy brains
Some cases of familial frontotemporal dementia (FTD) leading to frontotemporal lobar degeneration (FTLD) are caused by mutations in tau on chromosome 17 (FTDP-17). Certain mutations alter the ratio between four (...

Frontotemporal dementia in a large Swedish family is caused by a progranulin null mutation
Mutations in the progranulin (PGRN) gene have recently been identified in families with frontotemporal lobar degeneration and ubiquitin-positive brain inclusions linked to chromosome 17q21. We have previously des...

Open AccessPyroglutamate Abeta pathology in APP/PS1KI mice, sporadic and familial Alzheimer’s disease cases
The presence of AβpE3 (N-terminal truncated Aβ starting with pyroglutamate) in Alzheimer’s disease (AD) has received considerable attention since the discovery that this peptide represents a dominant fraction of ...

Open AccessAlzheimer’s disease pathology propagation by exosomes containing toxic amyloid-beta oligomers
The gradual deterioration of cognitive functions in Alzheimer’s disease is paralleled by a hierarchical progression of amyloid-beta and tau brain pathology. Recent findings indicate that toxic oligomers of amy...

Open AccessTransethnic meta-analysis of rare coding variants in PLCG2, ABI3, and TREM2 supports their general contribution to Alzheimer’s disease
Rare coding variants in TREM2, PLCG2, and ABI3 were recently associated with the susceptibility to Alzheimer’s disease (AD) in Caucasians. Frequencies and AD-associated effects of variants differ across ethniciti...

Open AccessBinding of α-synuclein oligomers to Cx32 facilitates protein uptake and transfer in neurons and oligodendrocytes
The intercellular transfer of alpha-synuclein (α-syn) has been implicated in the progression of Parkinson’s disease (PD) and multiple system atrophy (MSA). The cellular mechanisms underlying this process are n...

Open AccessDual-task tests discriminate between dementia, mild cognitive impairment, subjective cognitive impairment, and healthy controls – a cross-sectional cohort study
Discrimination between early-stage dementia and other cognitive impairment diagnoses is central to enable appropriate interventions. Previous studies indicate that dual-task testing may be useful in such diffe...

Article
The existence of Aβ strains and their potential for driving phenotypic heterogeneity in Alzheimer’s disease
Reminiscent of the human prion diseases, there is considerable clinical and pathological variability in Alzheimer’s disease, the most common human neurodegenerative condition. As in prion disorders, protein mi...

Article
Open AccessAstroglial tracer BU99008 detects multiple binding sites in Alzheimer’s disease brain
With reactive astrogliosis being established as one of the hallmarks of Alzheimer’s disease (AD), there is high interest in develo** novel positron emission tomography (PET) tracers to detect early astrocyte...

Open AccessAmyloid, tau, and astrocyte pathology in autosomal-dominant Alzheimer’s disease variants: AβPParc and PSEN1DE9
Autosomal-dominant Alzheimer’s disease (ADAD) may be associated with atypical amyloid beta deposits in the brain. In vivo amyloid imaging using 11C-Pittsburgh compound B (PiB) tracer has shown differences in bind...

Open AccessGenome-wide meta-analysis for Alzheimer’s disease cerebrospinal fluid biomarkers
Amyloid-beta 42 (Aβ42) and phosphorylated tau (pTau) levels in cerebrospinal fluid (CSF) reflect core features of the pathogenesis of Alzheimer’s disease (AD) more directly than clinical diagnosis. Initiated b...
