Amyloid Fibrils

Amyloid Fibrils

Amyloid fibrils are aggregates of misfolded proteins. Under most circumstances, misfolded proteins are either refolded by chaperone proteins or degraded by the proteasome. However, in the case of a mutation or a disease, these proteins can accumulate to form large clusters and often further assemble to form elongated fibers, called fibrils.
Amyloid deposits were observed as early as 1639 in the liver and the spleen. In 1854, Rudolph Virchow performed iodine staining,...

Neural Regulation

Neural Regulation

Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.

Alzheimer's Disease: Overview

Alzheimer's Disease: Overview

Alzheimer's Disease (AD) is a continually advancing neurodegenerative disorder, distinguished by escalating memory loss, cognitive dysfunction, and dementia. The disease unfolds in three stages: preclinical, mild cognitive impairment (MCI), and dementia. Its onset is insidious, and the progression gradual, with the cause not well explained by other disorders.
The clinical diagnosis of AD hinges on the presence of memory and other cognitive impairments. Biomarkers, such as changes in Aβ...

Area of Science:

Neuroscience
Alzheimer's Disease Research
Neural Network Dynamics

Background:

Alzheimer's disease (AD) is characterized by severe cognitive decline.
Amyloid beta-protein (Aβ) accumulation is a key factor in AD pathogenesis.
Cognitive functions depend on interconnected neuronal networks.

Purpose of the Study:

To understand the neural mechanisms of Aβ-induced brain dysfunction in AD.
To investigate how Aβ affects neuronal properties and network dynamics.
To explore potential therapeutic strategies for AD.

Main Methods:

Studying Aβ effects on neural network dynamics in vitro and in vivo.
Utilizing transgenic AD models with Aβ overproduction.
Analyzing electroencephalographic (EEG) activity alterations.

Main Results:

Aβ application can induce EEG slowing and diminished network oscillations.
These EEG changes mimic those observed in AD patients.
Experimental models allow for mechanistic studies of Aβ-induced dysfunction.

Conclusions:

Aβ significantly impacts neural network dynamics, leading to cognitive deficits in AD.
Investigating Aβ-induced neural dysfunction provides fundamental insights into AD.
This research may pave the way for novel AD treatments.
