Human cyclophilin 40 unravels neurotoxic amyloids.

PLoS Biology, 2017
The accumulation of amyloidogenic proteins is a pathological hallmark of neurodegenerative disorders. The aberrant accumulation of the microtubule associating protein tau (MAPT, tau) into toxic oligomers and amyloid deposits is a primary pathology in ...

Amyloid Beta and Tau Cooperate to Cause Reversible Behavioral and Transcriptional Deficits in a Model of Alzheimer’s Disease

Cell Reports, 2019
Summary: A key knowledge gap blocking development of effective therapeutics for Alzheimer’s disease (AD) is the lack of understanding of how amyloid beta (Aβ) peptide and pathological forms of the tau protein cooperate in causing disease phenotypes ...

Binding of Hsp90 to Tau Promotes a Conformational Change and Aggregation of Tau Protein

Journal of Alzheimer's Disease, 2009
Tau pathology, associated with Alzheimer's disease, is characterized by the presence of phosphorylated and aggregated tau. Phosphorylation of tau takes place mainly in the vicinity of the tubulin-binding region of the molecule and its self aggregation is also mediated via this tubulin-binding region.

QBP1 Peptide as a Potential Anti‐Amyloidogenic Therapy for Type 2 Diabetes: An In Vitro Study

Advanced Science, EarlyView.
The anti‐amyloidogenic peptide QBP1 effectively halts human islet amyloid polypeptide (hIAPP) aggregation, preventing the formation of toxic β‐structured intermediates. Through a combination of biophysical assays, molecular dynamics, and cell‐based studies, QBP1 is shown to preserve β‐cell viability and metabolic homeostasis, positioning it as a ...

Sensitivity analysis of a mathematical model of Alzheimer's disease progression unveils important causal pathways

Frontiers in Neuroinformatics
IntroductionMathematical models serve as essential tools to investigate brain aging, the onset of Alzheimer's disease (AD) and its progression. By studying the representation of the complex dynamics of brain aging processes, such as amyloid beta (Aβ ...

Expression of Tau Protein and Tau mRNA in gastric carcinoma

Asian Journal of Medical Sciences, 2015
Aims and Objectives: To provide theoretical basis for the gastric carcinoma pathogenesis and the clinical targeted therapy.  Materials and Methods: We detected the expression of Tau protein and Tau mRNA in 60 cases of gastric carcinoma tissues (observation group) and 10 cases of normal gastric tissues (control group). Immunohistochemisty was adopted to

Gut Microbiota Regulates Systemic Inflammatory Response and Compensatory Anti‐Inflammatory Response Syndromes by Targeting PF4+ Macrophages in Acute Pancreatitis

Advanced Science, EarlyView.
ABSTRACT Acute pancreatitis (AP) begins with pancreatic local inflammation, leading to the onset of systemic inflammatory response syndrome (SIRS), followed by compensatory anti‐inflammatory response syndrome (CARS), which causes immune paralysis and higher mortality rate.

Paternal Circadian Disruption Impairs Offspring Cognition via Sperm microRNAs

Advanced Science, EarlyView.
Paternal circadian disruption remodels the sperm small RNA payload, elevating miR‐92a‐3p/miR‐25‐3p levels and perturbing early embryonic gene regulatory programs. Microinjection experiments and single‐embryo transcriptomics reveal sex‐specific developmental vulnerabilities, ultimately impairing offspring hippocampal synaptic plasticity and cognition ...
