Exploring Biomolecular Self-Assembly with Far-Infrared Radiation

open access: yesBiomolecules, 2022
Physical engineering technology using far-infrared radiation has been gathering attention in chemical, biological, and material research fields. In particular, the high-power radiation at the terahertz region can give remarkable effects on biological ...

The amyloid precursor protein: beyond amyloid.

open access: yesMolecular neurodegeneration, 2006
The amyloid precursor protein (APP) takes a central position in Alzheimer's disease (AD) pathogenesis: APP processing generates the beta-amyloid (Abeta) peptides, which are deposited as the amyloid plaques in brains of AD individuals; Point mutations and duplications of APP are causal for a subset of early onset of familial Alzheimer's disease (FAD ...

Night‐to‐night variability in sleep and amyloid beta burden in normal aging

open access: yesAlzheimer’s & Dementia: Diagnosis, Assessment & Disease Monitoring, 2023
INTRODUCTION Alzheimer's disease is associated with sleep disturbances and accumulation of cerebral amyloid beta. The objective was to examine whether actigraphy‐detected sleep parameters might be biomarkers for early amyloid burden. METHODS Participants

Implication of tau propagation on neurodegeneration in Alzheimer’s disease

open access: yesFrontiers in Neuroscience, 2023
Propagation of tau fibrils correlate closely with neurodegeneration and memory deficits seen during the progression of Alzheimer’s disease (AD). Although it is not well-established what drives or attenuates tau spreading, new studies on human brain using

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

open access: yesFEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential

open access: yesFEBS Letters, EarlyView.
Aging reshapes the gut microbiome (↓SCFA‐producing commensals; ↑pro‐inflammatory outputs), shifting circulating metabolites (↓SCFAs; ↑LPS, ↑TMAO, ↑PAA) that act at the BBB to increase nonspecific transcytosis, alter transport, and promote astrocyte reactivity, heightening brain vulnerability.

Ectodomain shedding of the amyloid precursor protein: Cellular control mechanisms and novel modifiers [PDF]

open access: yes, 2006
Proteolytic cleavage in the ectodomain of the amyloid precursor protein (APP) is a key regulatory step in the generation of the Alzheimer's disease amyloid-beta (A beta) pepticle and occurs through two different protease activities termed alpha- and beta-

Engineering peptides into antibodies—opportunities and strategies for therapeutic innovation

open access: yesFEBS Letters, EarlyView.
Peptides and antibodies occupy complementary therapeutic niches. Peptides recognize difficult targets in a compact format, while antibodies add specificity, long half‐life, and effector functions. This review examines strategies that merge both modalities—peptide grafting into loops, terminal and Fc fusions, and bioconjugation—highlighting how ...

Patterns of amyloid accumulation in amyloid-negative cases

open access: yesNeurobiology of Aging, 2022
Introduction: Amyloid staging models showed that regional abnormality occurs before global positivity. Several studies assumed that the trajectory of amyloid spread is homogeneous, but clinical evidence suggest that it is highly heterogeneous. We tested whether different Aβ-patterns exist by applying a clustering on negative scans and investigating ...
