24 Questions
What is the role of inflammation in the normal function of the brain?
It is necessary for normal brain function
Which protein aggregates in Lewy bodies in Parkinson's disease?
Alpha-synuclein
What is the process of ubiquitination involved in?
Targeted degradation of intracellular proteins
Which type of protein aggregation disrupts other signaling cascades and sequesters proteins?
Alpha-synuclein aggregation
What may be the result of misfolded and/or aggregated proteins in neurodegenerative conditions?
Linkage to appearance of pathological hallmarks and neurotoxicity
Why is drug discovery currently facing challenges in Alzheimer's disease?
The drugs are only targeting ABP and neglecting other pathways
What is the central role of glutamate receptors in excitotoxicity?
Contribute to neuronal death
What is the role of amyloid beta plaques (ABP) and tau neurofibrillary tangles (TNTs) in Alzheimer's disease?
ABP and TNTs contribute to neurocompromise and neuronal loss
What is the significance of trophic factor withdrawal in relation to Alzheimer's disease?
Trophic factor withdrawal is believed to be an important factor in causing Alzheimer's disease
What happens when tau, a protein involved in neuronal communication, becomes phosphorylated?
It leads to neurocompromise by becoming blocked
How is the availability of proteasome related to neurodegenerative diseases?
Decreased proteasome availability leads to the aggregation of proteins
What is the association between BDNF (Brain-Derived Neurotrophic Factor) and Alzheimer's disease?
Loss of BDNF correlates with Alzheimer's disease
What is the potential consequence of trophic factor withdrawal in relation to Alzheimer's disease?
Increased neuronal cell death
How does phosphorylated tau impact neuronal communication?
Inhibits the neurocompromise process
What is the role of necrosis in Alzheimer's disease, as suggested by the text?
It is now considered more important than previously thought
What is the likely impact of decreased availability of proteasome in the context of neurodegenerative diseases?
Accumulation of aggregated proteins
What potentially happens in the mitochondria that could impact neurons and contribute to neurodegenerative conditions?
Mitochondrial dysfunction affecting neurons
What correlates with Alzheimer's disease more strongly than amyloid beta plaques, according to the text?
Phosphorylated tau
What is the process that heavily ubiquitinated proteins undergo in the cell?
Recognition by the proteasome
What is the potential consequence of stimulating the proteasome too much in the context of Alzheimer's disease?
Disruption of normal cellular processes
In neurodegenerative conditions, misfolded and/or aggregated proteins might be linked to which of the following?
Appearance of pathological hallmarks
What disrupts other signaling cascades, sequesters proteins, or causes other proteins to become misfolded in the context of aggregated proteins?
Phosphorylated tau
What is the result of excess glutamate leading to cell death?
Excitotoxicity
What type of protein aggregates in Lewy bodies in Parkinson's disease?
Alpha-synuclein
