CCD vs AD Poster Flashcards
(23 cards)
What is tau protein?
stabilizes neuronal microtubules under normal physiological conditions
what is hyperphosphorylated protein?
occurs when a biochemical with multiple phosphorylation sites is fully saturated
why is hyperphosphorylated protein bad
causes tau to lose its original microtubule stabilization activity - neuronal damage
what is microglia?
primary immune cells of the central nervous system
What is an astrocyte?
subtype of glial cells that make up the majority of cells in the human central nervous system (CNS)
What are glial?
Any of the cells that hold nerve cells in place and help them work the way they should
what is a neurofibrillary tangle
abnormal accumulations of a protein called tau that collect inside neurons.
why are neurofibrillary tangles bad
block the neuron’s transport system, which harms the synaptic communication between neurons
What is rostral?
towards head
What is caudal?
towards tail
What is Immunohistochemistry?
lab technique that uses antibodies to detect antigens in a tissue sample
What is an antigen?
Any substance that causes the body to make an immune response against that substance.
What is IBa1?
Ionized calcium binding adaptor molecule 1, pan-microglial marker whose expression increases with microglial activation
What does increased microglia mean?
overactive microglia can contribute to the death of healthy neurons, which may cause the disease to progress more rapidly
S100B
S-100 calcium-binding protein,
T231
Detects Tau when phosphorylated
Bete-amyloid
necessary for hippocampal synaptic plasticity and memory, abnormal levels clump together to form plaques that disrupt cell function
what is synaptic function
transmit nerve impulses between two nerve cells (neurons) or between a neuron and muscle cell
CCD symtoms
doesn’t recognize familiar people, gets confused, turns away from petting, diffrent tail wagging, barks for no reason at night, stops greeting you, messes in the house
canine cognitive dyfunction patients average age
8-9
AD symtoms?
memory loss, language difficulties, and challenges in performing daily activities
what enrichment changes can help with ccd
exercise, new and interactive toys, and learning new tasks
Why the hippocampus?
involved in memory, learning, and emotion.
