W/c part of an Alzheimers patient's brain does entaglement occur?
|
neocortex and hippocampus
|
|
What occurs w/in the cell body of neurons?
|
neurofibrillary tangles
|
|
What occurs at the end of the neutrites

senile plaques form - these are dense extra cellular aggregates
|
|
What is the consequence of tangles?
|
neuron cells are lost
|
|
What is found in the blood vessels of the brain?
|
amyloid bodies
|
|
What is the principal component of the senile plaques and amyloid bodies?
|
beta amyloid protein
|
|
What is the precursor of beta amyloid protein that gets cleavaged prior to producing b.a.b.
|
APP - Amyloid precursor protein
|
|
What enzyme is responsible for the APP cleavage?
|
secretase
|
|
What is observed when the last 100 residues of truncated APP gene was used?
|
no senile plaque formation but neurodegeneration occured
|
|

|
1) Phenylalanine (more hydrophobic) instead of Valine at site 717
2) Asparagine and Leucine instead of Lysine and Methionine |
