Antischkow cells are characteristic of the
**Core Concept**
Antischkow cells, also known as Alzheimer's cells or tangle-bearing cells, are a type of neuron that exhibits distinctive pathological changes in neurodegenerative disorders. These cells are characterized by the presence of paired helical filaments (PHFs) and neurofibrillary tangles (NFTs) within their cytoplasm.
**Why the Correct Answer is Right**
The correct answer is associated with Alzheimer's disease, a progressive neurodegenerative disorder that affects cognitive function and memory. Antischkow cells are a hallmark feature of Alzheimer's disease, where they are found in abundance in the hippocampus and cerebral cortex. The presence of these cells is a result of the abnormal phosphorylation of tau protein, which leads to the formation of PHFs and NFTs. This process disrupts normal cellular function and contributes to the progression of the disease.
**Why Each Wrong Option is Incorrect**
**Option A:** Not directly related to Antischkow cells, which are specific to Alzheimer's disease.
**Option B:** Lewy bodies are characteristic of Lewy body dementia, not Alzheimer's disease.
**Option C:** Pick bodies are associated with subacute sclerosing panencephalitis (SSPE), a rare condition caused by measles virus.
**Option D:** Negri bodies are characteristic of rabies virus infection.
**Clinical Pearl / High-Yield Fact**
Antischkow cells are a key diagnostic feature of Alzheimer's disease, and their presence can be used to distinguish it from other neurodegenerative disorders. It's essential to recognize these cells in histopathological examination to make an accurate diagnosis.
**Correct Answer:** C.
