Alzheimer type II astrocyte
Alzheimer Type II Astrocyte
Alzheimer Type II Astrocyte (pronunciation: alz-hy-mer type two as-tro-site) is a specific type of astrocyte that is typically found in certain neurological disorders, most notably hepatic encephalopathy and Wilson's disease. The term is named after the German psychiatrist and neurologist Alois Alzheimer, who first described these cells.
Etymology
The term "Alzheimer Type II Astrocyte" is derived from the name of Alois Alzheimer, who first identified these cells, and the Greek word "astrocyte", which means "star cell". The "Type II" designation is used to differentiate these cells from other types of astrocytes.
Description
Alzheimer Type II Astrocytes are characterized by their large, pale nuclei, which are often twice the size of normal astrocyte nuclei. These cells are typically found in the cerebral cortex and basal ganglia of individuals with hepatic encephalopathy or Wilson's disease.
